Kernel Recipes 2015: Multi-campus Layer 2 Network Fabric: what?, why? How?
2 likes1,255 views
The document discusses a multi-campus Layer 2 network fabric using TRILL (Transparent Interconnection of Lots of Links) for large-scale multi-tenancy and seamless VM mobility. It addresses challenges like nickname collisions and redundancy in gateway management while outlining the evolution and future development of TRILL in conjunction with Open vSwitch. Key insights include topology management and the aim to reduce latency through programmable network cards.

- 20. HAVING MANY GATEWAYS? choose the closest RBridge? What if it fails? What if the return path is different?
- 21. PSEUDO GATEWAY Uniform way to go outside the campus Manage redundancy themselves
