1. Why NGN?

Technological necessity of NGN

Does the Internet continue to evolve?

Best-effort QoS: New applications are hard to developCommercial quality real-time communications are difficult to provide

TV conference, streaming, …

Security/Reliability: Not carrier-gradeChildren/elders can’t apply patches everyday

Mobility: the next bonanza will be in mobile gadgetsCurrent (ordinary) IP assumes fixed network

Discussions at Linux Symposium (2006)

The Internet created various applications thanks to the freedom of end-users.Does it apply to IPTV, Web 2.0, or FMC?

7

Limitation from IP’s principle

• Routing table are updated in local manner; no network-wide, no equipment-wide sync scalable and cheap, but no QoS guarantee becomes possible

• No state in routers; minimize memory access expandable and faster, but traffic engineering becomes unavailable

• Very limited functions in networks interoperable ‘Internet Protocol’, but no security, no QoS-awareness

Principle of IP

The problems tightly linked with IP principle and merits

8

IP Design Philosophy: Main Goals

• Effective multiplexed utilization of existing networks– Packet switching, not circuit switching

• Continued communication despite network failures– Routers don’t store state about ongoing transfers– End-hosts provide key communication services

• Support for multiple types of communication service– Multiple transport protocols (e.g., TCP and UDP)

• Accommodation of variety of different networks– Simple, best-effort packet delivery service– Packets may be lost, corrupted, or delivered out of order

• Distributed management of network resources– Multiple institutions managing the network– Intradomain and interdomain routing protocols

Grosshauser (2002)

9

Characteristics of the Internet

• The Internet is– Decentralized (loose confederation of peers)– Self-configuring (no global registry of topology)– Stateless (limited information in the routers)– Connectionless (no fixed connection between

hosts)

• These attributes contribute– To the success of the Internet– To the rapid growth of the Internet– …and the difficulty of controlling the Internet :<

Grosshauser (2002)

10

Operator Philosophy: Tension with IP

• Accountability of network resources– But, routers don't maintain state about transfer– But, measurement isn’t part of the infrastructure

• Reliability/predictability of services– But, IP doesn’t provide performance guarantees– But, equipment is not very reliable (no ‘five-9s’)

Downtime: IP networks: 471min/year, POTS: <5min/year

• Fine-grained control over the network– But, routers don’t do fine-grain resource allocation– But, network self-configures after failures

• End-to-end control over communication– But, end hosts adapt to congestion– But, traffic may traverse multiple domains

Grosshauser (2002)

11

But operators cannot rely on PSTN services any more

In most developed countries,

2000 or around was the peak of telephone traffic

12

We must make Operator-friendly IP networks

• NTT: trial starts by the end of fiscal 2006• KDDI: Fixed network becomes all-IP by fiscal 2007• BT: by 2008• Korea: long-distance is by 2007, local by 2010

IP traffic > telephone trafficFiscal 2004: 34.1Gbps

(in Japan: converted 533k Erlang using 64kbps/call)

> -5%/year

May 2006: 524Gbps(Public Internet in Japan)

> 20%/year

Timeline

IP must be the base of future networks

13

NGN: best mix of packet and circuit

• "Service Stratum" for per-session control of packet transmission• Data is transmitted with IP packet for interoperability• All necessary functions are in the network (fat network approach)

– Operators can maintain every aspect of functions increase reliability– All the terminals can do is just to call network’s functions increase security– Control interface is open promotes development of applications

2. Standardization process

15

De jure standards v. De facto standards

• Open and fair process• Results are shared among

all participants (usu. without charge)

• Reflects broader opinions

De jure standards

• Operated by highly motivated volunteers

• Faster standardization• Currently very popular

NGN functional architecture (Y.2012)

• Transport stratum for managed IP packet transfer, and Service stratum for session control and for additional services, are clearly separated.(Does not align with OSI model; e.g., transport stratum includes session)

• Transport stratum: composed of Transport Function for IP packet transmission, NACF for user attachment (authentication, IP address assignment, etc.), and RACF for QoS

From ITU-T Y.2012 (06/07)

• Service stratum: composed of SCF for IMS and PSTN/ISDN emulation, and support functions for developing applications

• Terminal: for 3G terminals: IPv6, for traditional fixed-network terminals: IPv4

• 3rd Party applications for Open Mobile Alliance (OMA) works on Application Network Interface (ANI)

IMS (IP Multimedia Subsystem) overview

• Provides various SIP-based services– Provides session control, charging, security functions

• Increase end-user’s experience by unifying registration, authentication and charging

– Provides interfaces to control transport functions• QoS, media gateway, alignment of charging on transport functions

and service functions

– Provides interfaces not only to operators, but 3rd party application vendors

• Clearly defined SIP from operator’s point of view– IETF SIP is not enough for network operators

e.g., IETF SIP does not define the start and the end of charging

• ITU-T NGN refers 3GPP Release 7 IMS

IMS for NGN (Y.2021)

• CSCF (Call Session Control Function): SIP server, the core of this architecture. P-CSCF (Proxy CSCF) is a sip server that communicate with user terminals

• Various functions are defined as the gateway to other networks

30

Per-session Resource and Admission Control Functions (Y.2111)

• End-user (terminal) requests SCF a session establishment

• RACF manages the current network resources, and grant/reject the request to achieve QoS guarantee

– Relative QoS (e.g., diffserv’s CoS) is acceptable– Various message flow and protocols are defined, operators will choose

• ETSI NGN Release 1 defines RACF for access network onlyITU-T defines core network RACF as well

Structure of NGN Study/Standardization in Japan

Next Generation IP Network Promotion Forum• Combines strength of operators, vendors, academies, domestic fora and application vendors to promote all-IP networks • Established in December 2005, 211 members (March 2006)• Promotes interoperability tests, demonstration experiment, information exchange as well as standardization based on R&D• Technological focus: QoS and function, dependability (security and safety), interoperability and interconnectivity

TTC (Telecommunication Technology Committee)• Develops NGN-related technical standards as a committee to establish telecommunication related standards and protocols• Created NGN architecture WG and NGN upstream SWG in April 2005• Collaborates and contributes to ITU-T and various foreign fora such as 3GPP and 3GPP2 MIC

Practices proving test, if necessary.

•

• Promotes R&D and the standardization of its results by establishing basic strategies and promotion methods, and by practicing proving tests. R&D focuses not only on NGN R1&R2, but beyond R2.

• Promotes deployment and information exchange of next generation IP networks. Publicize appropriate information through publications, symposiums and market promotions. Surveys domestic and international R&D trends.
