Of the two,Virtualization is the more fundamental advance

– Implementing network functionality on COTS (i.e. Intel)

– Improved abstraction and functional modularity

– Improved economics– Improved agility

NFV (Network Function Virtualization)

– Separating network control and data planes

– Enables centralized NFV control of distributed, programmable network elements

– Improved manageability

SDN (Software-Defined Networking)

Secure QoS Tunnel

Why is Sonus interested in NFV?

Interworking Application Signaling Domains

Securing Application Domains

Enabling Application Control of Network Services

– When you need to communicate between applications

– Large-scale security and DOS protection

– When you need more than “best efforts”

• Industry’s First Example of Carrier-Grade NFV SBC• Common Codebase & Feature Set with HW-based SBC

Technology Implications

It’s no longer just about specialized hardware– Virtualize (NFV)

It’s no longer about unmanageable networks– Decompose (SDN)

It’s no longer just about Voice– Diversify (Video and Web Interworking & Policy)

It’s no longer just about Voice– Ubiquify (Service delivery over IP)

– over SIP trunks– over 3G/4G enablement

Is Open Source the Key to NFV Success?

• Open Source stops single vendor silos• As an SBC vendor, we only provide part of the NFV

solution• Well supported Open Source project can complete the

network– Management API’s (REST)– Router, firewall and other modules– Virtual switches – QoS, traffic shaping steering

• Plug into SDN

CAN TELCOS BUILD ON OPEN SOURCE?

Open source success: Hundreds / thousands of carriers build on Asterisk, FreeSWITCH, Kamailio, on COTS.

Scalable and Resilient: Yes - with innovations in the area of five 9’s where there are fewer models to replicate.

ON THE SHOULDERS OF GIANTS

Reference Amazon Web Services as gold standard development environment.

Follow ‘best practice’ architecture for scalable web applications. All components to be stateless except those which are

explicitly and minimally data stores All interfaces must be open ‘service interfaces’ No shared data stores or memory between components No backdoors or cross component assumptions, all

interfaces must be fully implemented and policed No reinventing the wheel - reuse existing technology

wherever possible

Leverage Agile iterative and incremental development software development techniques

All components to be minimal in size and scope rather than maximal

Everything to be architected (not necessarily implemented) to scale to 100M subs

WEB METHODS | WEB SCALE- Google: 2 trillion searches in 2012, 200M/hr- Facebook: 2012: Users online ~1 billion mins/hr- Netflix: Streams 5B hrs per qtr, 140M mins/hr- YouTube: Serves 6B hrs a month, 500M mins/hr- Amazon: EC2 estimated at 100,000-1M servers

INNOVATION REVOLUTION: AT WEB SCALE AND INTERNET VELOCITY

1. Collaborative efforts

2. Build on each others achievements

3. Give back to the community

WEB METHODS EQUALS WEB SCALE

Massively scalable SIP call control implementation Delivering IMS Core components (and more)

Designed from the ground for the Cloud

Modeled on web design patterns for scalability, reliability and security Components kept largely stateless and storing Long-lived state stored in clustered data stores Currently testing at 50M + BHCA Trusted/untrusted zones w/security groups / FW rules

Highly portable - already demonstrated on VMware, OpenStack, Windows Azure Development system in Amazon EC2 Cloud Projected running costs < $0.02 per subscriber / year

Released as open source in May 2013

First VNF adopted by the CloudNFV PoC consortium
