The document discusses the concept of open networking and software-defined networking (SDN), emphasizing the need for network operators to manage their infrastructures flexibly and efficiently through open interfaces. It highlights the importance of avoiding vendor lock-in and fostering innovation through published and accessible interfaces and APIs. Additionally, an announcement for a new educational open-source tool called ONF SampleTap, aimed at helping users experiment with OpenFlow app development, is made.

• “Open” networking & SDN
• Relation to the rest of the “Open” world
• An announcement from ONF

What network operators are telling us
3
We want to manage our network(s) in one way
 Common tools for fixed, WL, optical
 Totally flexible infrastructure
We want to create our own services, quickly
 Open interfaces to an abstracted network
 For us and for our customers
We can’t afford vendor lock-in
 Open interfaces to networking equipment
 Optimized HW, remote SW we control

Open interfaces in SDN

Right places to foster innovation above and below
• Apps  Control Plane
• NBIs (de facto)
• Control Plane  Data Plane
• OpenFlow (de jure)
• Client  Switching Silicon
• HAL/SDK API (?)
• “Open” = published, available, &:
• Not controlled by a single party
Open Networking: Peer-peer protocols replaced by interfaces & APIs

Open Networking in a nutshell

Separate control & data planes
• De jure standard protocol between
Network abstraction to applications
• De facto standard APIs between
Nothing controlled by a single party
• Community-based
