AGENDA

§  Time for a change – Introducing Project Clearwater

§  Why the cloud?

§  Designing for the cloud

§  Clearwater function and architecture

§  Clearwater use cases

§  Project Clearwater Ecosystem

§  Case study

TIME FOR A CHANGE

§  IMS is "business as usual" for Tier 1 telco vendors §  Complex and costly §  Long release cycles §  Closed and proprietary implementation §  Typically on proprietary hardware

§  This model enables OTT providers to run rings around telcos §  In-house software expertise §  Continual innovation §  Rapid release cycles §  Creative use of Cloud technology and open source software

NETWORK FUNCTIONS VIRTUALIZATION

13 operators leading Industry Specification Group on NFV under auspices of ETSI

“The new network will be built on high volume industry-standard servers, storage elements, ethernet switches and IT systems running software apps from

independent developers”

Operators embracing the concept of the "Software Telco"

ROUTES TO NETWORK FUNCTIONS VIRTUALIZATION

Proprietary Hardware

Standard Hardware

Virtualized Environment

Implement all hardware-specific

functions in software

Design for standard hardware

Design for the Cloud

Adapt software to virtualized environment

Project Clearwater

WHAT DOES IT MEAN TO DESIGN FOR THE CLOUD?

§  Using the same architectures as before is missing the point

§  “Stand on the shoulders of giants” §  Telcos used to have the highest scale systems §  Not so any more: Google, Amazon, Facebook etc etc

SCALABILITY OF TOP INTERNET PROVIDERS

§  Google §  Served 2 trillion searches in 2012, 200 million an hour

§  Facebook §  As of June 2013, users spent ~1 billion minutes an hour

§  Netflix §  Streaming over 2 billion hours of video per month, 165 million minutes

an hour

§  Youtube §  6 billion hours a month, 500 million minutes an hour

§  Amazon §  In 2012 EC2 estimated to consist of 100,000-1M physical servers

WHAT DOES IT MEAN TO DESIGN FOR THE CLOUD?

§  Using the same architectures as before is missing the point

§  “Stand on the shoulders of giants” §  Telcos used to have the highest scale systems §  Not so any more: Google, Amazon, Facebook etc etc

§  New ways to create massively scalable systems §  Very well proven §  Culture is very open

§ experiences with design patterns (blogs, conference talks, ...) § open source components

§  New philosophical approaches §  APIs, APIs, APIs – it’s all about the ecosystem §  Move fast – re-use rather then re-invent §  Experiment – iterate and evaluate

CLEARWATER – DESIGN OBJECTIVES

§  Massive scalability

§  Highly robust and resilient

§  Built-in basic calling services

§  Compliance with IMS specs

§  Standalone capability

§  Business model innovation

CLEARWATER – OBJECTIVES MET

§  Massive scalability §  Tested at 10M subs, 20M BHCA: cost < €0.02 per sub per yr (EC2) §  Elastic scalability demonstrated

§  Highly robust and resilient §  Web-scale architecture, stateless SIP processing nodes §  N+M pools, geo-redundancy demonstrated

§  Built-in basic calling services §  Basic MMTel services included

§  Compliance with IMS specs §  Tested with HSS, TASs, MGCF, AGCF, P-CSCF

§  Standalone capability §  Built in mini-HSS used in lab trials and PoCs

§  Business model innovation §  Released as Open Source

CLEARWATER APPLICATION EXAMPLES

§  Free-standing consumer voice and video comms

§  Hosted business voice

§  VoLTE

§  Developer API Ecosystem

§  PacketCable 1.x migration to 2.x

§  Class 5 switch replacement

§  RCS – Messaging

§  WebRTC

PROJECT CLEARWATER ECOSYSTEM

The Project Clearwater Ecosystem brings together

partners with products and expertise in §  IMS technology

§  NFV infrastructure §  Systems Integration

to fast track deployments of the leading virtualized IMS solution

BENEFITS OF ECOSYSTEM

http://www.projectclearwater.org/ecosystem/

§  Interop testing has already been performed with all partner products

§  More partners expected over coming weeks

§  WebRTC is peer-to-peer technology

§  Peer-to-peer videoconferencing leads to vast amounts of bandwidth required/consumed

§  Video mixing requires significant compute resouces

§  Jitsi videobridge is a Selective Forwarding Unit, acting as a lightweight videoconferencing server §  Minimal processing, based in the cloud §  Reduces upstream bandwidth requirements from each client to single

video stream

§  Project Clearwater gateways IMS endpoints into Jitsi videobridge conferences
