Initial expectations for Open Networking

Programmability“In the datacenters, we don’t login to each of the virtual machines to configure them. Everything is automated. We want to do the same thing for the network.”- Urs Hoelzle, Google (ONS 2012)

Open and fast innovation“If you want a new function, we have to convince the vendors to implement. Even if we were able to do it, we have to wait for a long time “ - Igor Gashinsky, Yahoo (ONS 2011)

Challenges for Carrier-grade NFV/SDN

Controller

Switch ClusterHigh end router

Replacing a “Big Box” to a “Cluster of small modules” provides significant benefits, but also gives you many challenges

Orchestration of various components

• Skills to assemble numerous multi-vendor components

-> Key to solve: Simple architecture and a smart orchestrator

Carrier-grade NFV Platform

• Major vendors’ monopoly over key technologies for carrier requirements

-> Key to solve: Provide carrier-grade functionsas a common platform that can be widely used

Carrier-grade SDN architecture

• Use commodity switches for carrier WAN• Achieve high scalability and reliability-> Key to solve: A new design of SDN architecture
