Cloud & WAN – Challenges •  Lack of suitable abstractions

•  Non existent interfaces

•  Non dynamic and relatively rigid

•  Organizational boundaries

•  Inter-provider issues

WAN Extensions

•  Open Cloud Network Interface (OCNI) –  Networking Extensions to OCCI –  HTTP RESTful –  L3VPN, L2VPN, Openflow

•  Distributed Control Protocol (DCP) –  Configuration negotiation –  Link ,VLAN, Routing

protocol etc..

Conclusion

•  Operator network is a tremendous asset •  Operator network necessity for the Cloud

Network can be 1st Class cloud citizen

Reliable  On-­‐demand  

Simple  Interfaces   Sellable  Secure
