Problem:

Method:

  1. VDC + VDC allocation + VDC extend

  2. type-0 + type-1 + best-effort service
    • type-0 bandwidth guarantee
    • type-1 ingress/egress last and/or first hop guarantee
  3. port-switch + source-routing + (static switch)

Design:

  1. VDC manager -> build a signaling channel (STP)生成树,邻居相互通知各自的层数 etc.

Evaluation:

Conclusion:
