The document introduces Project Clearwater, a cloud-based IMS (IP Multimedia Subsystem) solution that leverages open-source software for scalability and innovation in telecom services. It highlights the shift from traditional proprietary systems to flexible, cost-effective architectures that support rapid deployment and adaptation in a competitive market. The project aims to create a robust ecosystem for IMS technology, incorporating collaboration with various partners to enhance deployment and interoperation.

- 1. THE BRAINS OF THE NEW GLOBAL NETWORK BRIDGING IMS INTO THE 21ST CENTURY WITH OPEN SOURCE SOFTWARE Piers Finlayson 28 April 2014 Metaswitch Networks | Proprietary and confidential | © 2014 | 1
- 2. 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
- 3. 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
- 4. 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"
- 5. 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
- 6. 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
- 7. 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
- 8. 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
- 9. PROJECT CLEARWATER – IMS IN THE CLOUD The Cloud Open Source Open Standard APIs + + = Massively scalable, very low cost, IMS-based mass-market VoIP services platform designed from the ground up to leverage the Cloud Business Model Innovation + www.projectclearwater.org
- 10. CLEARWATER – DESIGN OBJECTIVES § Massive scalability § Highly robust and resilient § Built-in basic calling services § Compliance with IMS specs § Standalone capability § Business model innovation
- 11. 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

- 13. 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
- 14. 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
- 15. BENEFITS OF ECOSYSTEM http://www.projectclearwater.org/ecosystem/ § Interop testing has already been performed with all partner products § More partners expected over coming weeks
- 16. § 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 WEBRTC VIDEOBRIDGE – CLEARWATER AND JITSI Metaswitch Networks | Proprietary and confidential | © 2014 | 16
