Distinguished Lecture Title: Converged Services and a New Generation of Networking

Tutorial Title: Services over IP: Implementation Options and Challenges

Dr. Bhumip Khasnabish (SM-IEEE and Distinguished Lecturer of the IEEE Communications Society) of ZTE USA Inc. delivered a Distinguished Lecture entitled “Converged Services and a New Generation of Networking” to members of the IEEE Communications (and often jointly with Signal Processing Society, and Circuits an Systems Society ) Society’s Mumbai, Pune, Hyderabad, IIT-Kharagpur, and Kolkata, chapters/sections in India. The lecture was divided into four parts. Dr. Khasnabish first discussed the evolution of voice service to the use of voice over the Internet protocol (VoIP), and showed how the use of VoIP over any wired and wireless device is commoditizing the voice communications service. Examples like Skype, GoogleVoice, MagicJack, etc. were discussed with an attempt to show how the device is becoming the service essentially utilizing low-cost or free access and transport for the voice communication session. This was followed by a discussion on IPTV and streaming media services, development of their standards, and the interoperability issues. Dr. Khasnabish also provided the latest updates on and a comparison of the emerging smart TV and NG TV development including the recently announced Google TV echo-system/service. The third part focused on emerging communication services including TeleMedicare and TelePresence/TruePresence and NGN architectures. Several emerging architectures and devices along with the hot topics like privacy and security, more granular traffic and service policy management, lack of standards and interoperability, and hurdles of new technology introduction were also discussed. In the fourth part, Dr. Khasnabish talked about (a) research topics in converged services and NGN areas, (b) a new generation of revenue models, and (c) the evolution of the regulations for communications and entertainment services, and how these rules are influenced by politicians and lobbyists instead of by the consumers (or their advocates). The lecture was followed by both formal and informal questions and answers, and discussion sessions.

Dr. Bhumip Khasnabish also delivered a tutorial entitled “Services over IP: Implementation Options and Challenges” in Mumbai, Pune, and Hyderabad chapters/sections. This three-part tutorial explained the current popular implementations of (a) voice over the Internet protocol (IP) or VoIP, (b) streaming media, on-demand video, and broadcast or live TV service over IP, and (c) messaging and other over the top (OTT) communications services including gaming, and file sharing. The activities of the major Standards organizations to resolve the interoperability and service quality issues were then reviewed. It was also demonstrated how the demand for converged services is driving the convergence of devices. The networks are increasingly becoming aware of the services, and the major service providers and equipment/solution suppliers are also supporting this new paradigm. The service providers’ challenges of 3Ps — protection from overload and unauthorized usage, prevention of failure and outage, and performance management — were then elaborated. The tutorial was interactive, and the attendees were allowed to interrupt the presentation if/when further clarifications were desired.

Report on IEEE Tutorial on ‘Services over IP: Implementation options and challenges,’ and

IEEE DL on ‘Converged Services and a New Generation of Networking’

by Dr. Bhumip Khasnabish, ZTE, USA

Report prepared by Dr. Avinash Joshi, Director, TechMahindra, Pune

IEEE Mumbai (Bombay) Section and Pune Subsection express sincere thanks Dr. Bhumip Khasnabish for

presenting excellent Tutorial sessions and Distinguished Lectures (DLs) in both Mumbai and Pune.

The educators (Faculty members) and the graduate students were highly satisfied with the lectures and

interactions with Dr. Khasnabish. Here are a few of the comments that the organizers of the events

received after the lecture and open discussion session: “Veteran leader and having excellent

understanding of the industry movement,” … “Energetic speaker, and answered all of the queries in

details,” … “We could have asked more questions but time was limited ... let's do this kind of session with

this speaker again next time.”

The professionals from the Telecommunications, wireless, and multimedia — including TV and video

distribution — Industries were benefitted from the guidance and sharing of Telecom industry pointers,

which are very critical for system developer and integration service providers alike. The practicing

engineers felt privileged for being in attendance because they got an opportunity to spend time with a

world class domain expert and leader. They also concluded that it was a superb event.

Further details about the questions and answers, type of audience, and concerns of both technical and

non‐technical persons are as presented in the following six sections.

(A) Questions and answers

How should resource management be done in Radio Access Networks?

Interlayer information on resource usage must be exchanged allowing higher layers to manage and

provision of resources to ensure QoS. Dynamic use of low/high bit‐rate codecs is also essential as

appropriate to type of device and service. Device/service profiles will also determine use of appropriate

radio resources for specific usage and service contexts.

Can toolkit approaches be simulated in various networks for IPTV services?

Yes. For example, MSF (www.msforum.org) developed access tile based approach to include a variety of

access paradigms in the network. The same approach can be used in simulators and simulation case

studies. Almost every network and enhancement in use today can be simulated via various tools

(MATLAB/Simulink and OPNET are a few examples). It is in fact imperative to be able to predict the

behavior of any proposed network enhancement before deploying it in the field.



How should organizations like BSNL evolve their service?

A toolkit based approach is necessary as network depends on services offered and their uptake.

Convergence of land‐based and Radio networks is another factor which needs to be taken into account

when evolving the network. Transcoding for content streams to appropriate formats is necessary in this

context. Resource management can be done dynamically by adopting correct low/high bit‐rate codecs

depending on network conditions. Use of queues and packet priorities is necessary along with routers

which honor them and is just another aspect of a toolkit based approach. Another dimension is

edge/smart caching and is essential to resource conservation as indicated by the experiences of content

delivery networks.

Should network management strategies be dynamic? What are the options?

Yes, definitely the dynamic mechanism is better. Constant monitoring and incorporation of the feedback

along with a toolkit approach which aggregates several optimization approaches is necessary to manage

different aspects of the network. A “one size” fits all approach does not apply, networks are very

dynamic and the exercise is necessary for appropriate provisioning and evolution. Cloud‐based systems

are prime examples of scenarios where resources are defined, dynamically added, removed and

scheduled for implementing services.

Why has IPTV uptake been low? What does the future hold?

This may be due to limited bandwidth in the past along with the high cost of IPTV services development

which would get passed to customers. Adoption of P2P principles is improving scalability along with 4G

radio techniques which can afford increased bandwidth at much lower access network development

costs. This makes IPTV much more attractive for mobile operators. The 3GPP is trying to bring in

IMS/IPTV strongly. Organizations like MSF and OpenIPTVForum are providing standardization effort.

Standardization adoption has been slow among vendors with limited participation for inter‐operation

demonstrational events. It is possible that vendors see that their role and niche are reduced with

standardization, but an increase in demand could address these concerns. Widespread acceptance

however does depend on these the success of standardization efforts. Ultimately demand will drive IPTV

and IMS service development by the operators.

What about security in clouds?

This is an open issue. Security is better integrated into applications and systems, tightly in order to

reduce the possibilities that the hackers can afford. However security is an ever evolving game, security

models have to evolve as new threats present themselves to applications and services. Numerous data

protection and authorization strategies exist but will evolve in the near term to fit cloud and various

other business models.

Are there any research issues related to cloud Computing?

Cloud Computing is very vast topic. If it is Internet based, we can share resources, software and

information. Client side and server side mechanism should be more efficient to make cloud computing



more reliable. Issues involve in server side and client side networks are major topic to be investigated, in

addition to the security, scalability, and seamless network extension.

How do we quantify the Quality of Experience?

Quality of Experience is measured in the application and service layer after the QoS parameters are

defined or vice versa. When the service/product is launched, the statistical information of various

service usages is considered. There may be single or multiple factors. So based on the response of the

subscriber with various factors after launching the service, the QoE parameters calculated. For example,

perceptual audio quality would be a part of voice QoE, and for IPTV, the channel change experience,

video clarity and continuity experience, etc. would be parts of video QoE.

Why there is a delay in IPTV response as compared to conventional live TV?

Presently, the availability of the bandwidth sometimes may delay the live telecast. In addition to that

the overheads, the processing (joining and leaving multicast groups) the IPTV channels and content

introduce additional delays. In the next generation versions of IPTV standards and with policy based

bandwidth management including the availability of higher bandwidth such delays should be reduced.

(B) Type of Audience

The audience consisted of students, faculty members, and professionals. The approximate distribution

of the audience is as follows: More than one hundred (100) Computer science and Engineering students,

twenty (20) faculty members from various institutions, and many Telecom and Information Technology

professionals from national and multi‐national organizations.

(C) How the policy makers can utilize the materials from the discussions and attendees' concerns in making new rules and regulations.

The discussion revealed valuable insights relating in the following areas.

ISP strategies and Monetization Policies

The US experience shows a tussle between various lobbies over modern IP based services. Internet/IP‐

based service providers host services accessed by users through their provider networks (ISPs). These

service providers advocate an “open network” policy, where consumers should have a choice in

accessing services on the information highway unfettered by the whims of ISPs. On the other hand, ISPs

would be happy to profit from the resulting data transfer loads on their networks. The legalities here

conflict with freedom of expression and consumer rights and have so far proved inconclusive. However,

ISPs in China have shown that bundling services innovatively with data plans helps monetize these loads

effectively. Chinese ISPs have tied up with internet services to provide personalized value adds with

which they bundle data plans, attractive to consumers. Evidently, pairing one essentially un‐monetizable

service with some other easily monetizable service is the way forward in improving value for both the



consumer and the ISP. This has also allowed those ISPs to circumvent tough legal issues by merely

directing traffic appropriately through provisioned network elements and profiling anonymous customer

service usage statistics. The wisdom gained here could save significant churn, public funds and private

investment if used in shaping government policies. Large state‐funded ISPs like BSNL in India could gain

by planning their network and service evolution strategies accordingly.

Net Neutrality Debates

Freedom of expression and consumer rights related legislations in most countries allow subscribers to

use services of their choice on the internet. The burden of the resulting network usage falls on ISPs. For

example, P2P users account for more than 60% of data traffic but only approximately 5% of the

subscriber revenues. The key question is whether ISP should differentiate between “their own” and

“other” traffic moving through their networks. Experiences show that P2P users cannot be blocked or

throttled without serious legal backlash. Technologies like P4P eliminate 70‐80% of long distance P2P

traffic, which has been a bleeding concern for ISPs. The remainder of the problem stems from aggressive

monetization policies which some ISPs wish to pursue. As experience shows, technology again comes to

the rescue ‐ customer service usage trends can allow ISPs to stay in the game through implementation

of innovative service bundling and billing policies.

Healthcare

The use of Telemedicine over the Internet has not spread widely yet, partly due to the limited focus of

the healthcare industry on custom Body Area Networks (BANs). Critical issues include lack of

standardization, seamless security and interoperability with the Internet at large. Standardization efforts

in other industries have reduced operational costs to service providers and ultimately to consumers.

Governments have a critical role to play in pursuing policies that would make patient data, healthcare

expertise and knowledge remotely accessible. This would improve the level of healthcare worldwide

without increasing the costs to patients as well as to the insurance industry.

IPv6

Internet Service Providers (ISPs) are realizing the values of an all‐IP network. The drawback here is the

limitation of the IPv4 address space in use today. Migration of internet devices and network elements to

the IPv6 addressing scheme can help realize the full potential of all‐IP networks. Several first‐world

countries now show trends where mobile devices outnumber populations by far. This points to a

burgeoning market for machine‐to‐machine (M2M) applications ranging from telemedicine to supply‐

chain management. Urgent IPv6 implementation is thus advisable for modern network infrastructures.

Government policy can play a pivotal role in enabling wide‐spread deployment of IPv6 devices and

networks.

Directions in Education and Research

A list of top research topics shows upcoming technological trends. These are technologies being evolved

at educational and commercial research laboratories worldwide, which will find their way into network



operations all over the world. Educational and research policies can well benefit from a knowledge of

these trends by investing the public funds appropriately for innovation.

Also significant is a need for policy makers, managers and implementers who are comfortable with these

emerging technologies. This is a key ingredient in designing policy and network operations which

complement each other.

Clouds are an important direction in research and institutions in India should actively pursue research on

cloud‐based systems. This experience would eventually find its way into industry leading to

industrial/commercial cloud‐based service in India with the expertise to build, sustain and evolve them.

Important applications of clouds include efficient service /energy management and creation of low‐cost

computing (communications) resources for service providers which will ultimately benefit the economy.

(D) Technical concerns of modern networks and services

Toolkit based approaches to network resource management

Networks are multi‐layered due to the large set of convergent features they offer to the subscribers.

While layering helps design and standardization, in many cases it hinders efficient operation and

management of the network. Experience shows management of resources in each layer has to be

consistent across all layers to get the most benefit out of a given network. Moreover, the same strategy

for network resource management does not work across all segments of networks. Networks are also

becoming more dynamic which means that strategies need to change dynamically. All of these can be

achieved through appropriate cross‐layer resource information sharing and using a toolkit based

approach for advising on optimal usage of resources. Such toolkits are being widely employed in overlay

networks for Computational Clouds and Content Distribution. As seen from current trends, such toolkits

are finding their way into Radio Access Networks as well as for converging core and transmission

networks. For example, Fraunhofer FOKUS provides test and development environment for a number

(http://www.fokus.fraunhofer.de/en/fokus_testbeds/index.html) emerging applications, services and

network management paradigms.

Simulation

Simulation strategies for every type of network or network enhancement are available or can be

developed using for example MATLAB/Simulink or OPNET, and can be used to evaluate toolkit based or

other approaches to network optimization. Numerous standards bodies also advocate various tools

which can be used by researchers all over the world.

Clouds

Clouds (http://trac.tools.ietf.org/area/app/trac/wiki/Clouds) are becoming typical settings to deploy

complex services to very large subscriber bases along with supporting toolkits. Currently, they are the

best paradigm to define and manage resources. Clouds are an important direction in research and

institutions in India should actively participate in this research area. The experience would eventually



find its way into industry leading to industrial/commercial service clouds in India with the expertise to

build, sustain and evolve them.

IPTV

Though IPTV has not been adopted widely, various enablers and corresponding business cases are

emerging. The combination of P4P and PSPP are becoming scalable enablers of IPTV delivery to

subscriber bases with hundreds of millions of users. Wireless Broadband reduces the cost of last mile

delivery of IPTV by as much as 70%. Cloud computing techniques allow efficient distribution and on‐

demand reformatting of media streams. This has revived the possibility of widespread IPTV usage

among mobile users. VoIP, Voice and Video conferencing along with user generated content are other

attractive off‐shoots of these technology developments and may see many innovative hybrid service

offerings being developed in this area.

(E) lifestyles/living‐standards of people

One can directly see benefits in areas of healthcare, distance learning, energy conservation,

infrastructure investment and entrepreneurship as a result of these technological developments.

From smart‐grids to telemedicine, better networks stand to benefit the consumers. Smart‐grids will not

only save consumers’ energy bills, these will also save national energy exchangers substantial amount of

money. Telemedicine can improve the level of healthcare by making experts’ knowledge available

universally. Distance education and access to information as well as entertainment will improve

awareness and opportunity even in remote parts of the world. All of these will contribute positively to

improving the lifestyle and living standards.

(F) ComEn businesses in the country (and in the world, overall)

Cheap, shared computing resources will allow entrepreneurs to expose their services at a lower cost to

world‐wide audiences, reducing the need for investments in physical infrastructure. Networked

applications which allow remote interaction and information sharing will allow businesses to operate at

a lower cost by delivering their expertise on demand to anywhere in the world.

Report on

IEEE Tutorial on ‘Services over IP: Implementation options and challenges’


Report prepared by Dr. Deergha Rao Korrai, Professor, Osmania University, Hyderabad

The tutorial is held on 13 July 2010 at Research and Training Unit for Navigational Electronics (NERTU) auditorium,

University College of Engineering, Osmania University, Hyderabad, India from 9AM to 1PM.

The local hospitality such as Air ticket from Hyderabad to Kolkata, lunch, accommodation, and travel in Hyderabad

has been arranged by the communications and Signal Processing societies’ joint chapter of the IEEE Hyderabad

section in association with TCS, Hyderabad.

The audiences for the tutorial are 55 including students, Research scholars, participants from industry, and faculty

from colleges.

Attendees posed some questions which were well answered by the speaker. The issues raised by the participants

are related to Mouth‐to‐ear delay calculation or estimation, GPS integration, location services, current status and

future infrastructure deployment, Speed of IPTV – status of current compression technology, cooperating Multi‐

modal devices, net enabled Health services, Security issues like DRM, Skype service, and emerging trends. Dr.

Khasnabish emphasized the need of interoperability, standardisation and protocol integration.

In feedback, the participants have expressed satisfaction with the event organization, suggested to continue this

kind of tutorials in future, and asked to increase the time for questions and answers.

The policy makers have to consider the concerns of Privacy, Intellectual property (IP) rights, Cyber crime and

security. Securing telecom networks against illegal interception is important, but equally important is enabling

facility for lawful interception and monitoring of the networks. Introduction of new technologies, services or

capabilities put citizens at risk. The need is that the Regulator, the service providers and the security agencies to

take a collective look at the existing scenario and build the requirement for having monitoring capability before

launching a service.

The majority of people do not yet enjoy the benefits of the digital age ‐ low cost communications and online

services that could support some of their real needs. Services over IP can help individuals, by engaging them in the

information society, to improve their quality of life, stay healthier, and live independently by enhancing their

mobility. The emerging concept of Ambient Intelligence offers great potential, with the possibility for the whole

environment to have embedded intelligence that helps solving everyday life's needs. Internet based Solutions

address daily and independent living such as: Social communication, daily shopping, travel, services and public

safety. Telemedicine opens up new opportunities for providing medical care to the home and there are many new

developments in Internet‐based home care, including ways of monitoring wellbeing and providing a secure home

environment, Communication for disaster warning and management is usually based on satellite system. Mobile

cellular or cable networks are not built to meet such emergencies. Next generation mobile networks must

incorporate satellite based emergency communications system for instantaneous communication in rural and

isolated areas at the time of emergencies.



Improving Business with better communications using IP networks

Business communications have become more complex. Indian businesses are demanding ways of simplifying

communications for their mobile and distributed workforce and their knowledge workers to improve

communication flows, enhance collaboration, and improve productivity. Knowledge workers from India operate in

today's global environment and frequently travel away from their offices or workgroups.

Unified communications integrates e‐mail, instant messaging, and calendaring applications with communications

devices and applications‐telephony‐wired and wireless. By using the network as a platform to enhance

comparative advantage by accelerating decision time and reducing transaction time with the security, resilience,

and scalability of the network, it enables users in any workspace to connect anywhere, anytime, and anyplace,

using any media, device or operating system.

Today when the Indian economy is growing in leaps and bounds, the number of knowledge workers is steadily

rising; unified communications is being viewed as the new paradigm for employee communication that improves

the flow of information and allows employees to reach each other. The Indian telecommunications market is

growing at a rapid pace spearheaded by the mobile industry. The mobile industry is adding more than six million

subscribers every month, making this to be one of the fastest growing markets in the world today. In such

conditions, a comprehensive IP communications system of voice, video, data, and mobility products and

applications can help organizations communicate more effectively, more securely, and in a more personal way.

The Future of IP Television Business

The entertainment industry is undergoing a dramatic transformation. The insertion of IP into the vertical video

industry has allowed for new encoding and transport mechanisms. This technology that delivers television and

value‐added video services using Internet Protocol is called IPTV. IPTV is expected to be the real killer application in

the Telco’s' broadband services portfolio. IPTV is interactive because of availability of return path ‐ therefore, it is

capable of providing Video on Demand (VOD), time shifted television, gaming and many other innovative

applications. Not only is the video delivery through cable and satellite being challenged, IP has enabled streaming

video over Internet. User generated content (UGC) is a reality today with portals like YouTube serving 100 million

videos per day.

In recent years, with increasing competition and price declines, telecom providers are turning towards IPTV

services as a way to support broadband penetration and increase their revenues. Currently there are 10M+

subscribers worldwide with approximately half of them in Europe and the total number of IPTV subscribers is

expected to increase to 65M over the next three years. In India, all major SPs have announced plans for IPTV

deployments. However, rollouts have been hampered by regulatory issues, content availability and the need to

upgrade access networks. The market is expected to gain pace in the future as India is big on entertainment;

consumers are willing to pay more for value added services. Finally, educational services could be enabled using

this IPTV technology.
