• “Networking” SDX – connectivity / routing– Layer 3 (IP) – e.g., connect AS’s– Layer 2 (Ethernet) – e.g., multi-domain circuits– SDN – connect SDN islands

• “Cloud service” SDX – with compute/storage– Connect SDI islands– Compute / storage / network / instruments– GENI as an early instance

What does a Virtualized Meet-Me Point look like?

Physical Meet-Me Point (Colo)

• Bring your own equipment• Cages keep us physically separate

Software Defined Exchanges (SDXs)

SDI SDX

Shared ResourceProvider A

Shared ResourceProvider B

Shared ResourceProvider C

A “meet me” point for services,e.g., BGP in one slice, Ethernet circuitsIn another, CDNs in a 3rd, etc.

Key research areas: federations, authN/Z,policy logics, cross-domain visibility, etc.

For me, next sequel started with Nick Feamster’s talk at the NITRD SDN workshop (NSF, Dec 2013)

Some questions for the panelists

• What is the approach that you have taken, or want to take, for building an SDX?

Given that no one agrees on exactly what an SDX is, it is important to understand each other's definitions

• What is the function of your SDX ?• What is the architecture and design of your SDX ?• What are the envisioned applications that it enables ?• What APIs are adopted in your SDX ?

Some broader questions

• What new capabilities can we create with SDXs ?(content distribution, security, instrumentation, peering control, . . .)

• What key research issues arise with SDX’s ?

• What are the timelines for SDX’s (prototyping, operations, inter-operation) ?

• How can we best combine a period of “thousand flowers” innovation with the need to interoperate between SDX’s ?
