Chapter 5 The Network Layer: Control Plane

5.1 Introduction

Per-router versus SDN control plane.

Two possible approaches for forwarding and flow tables are computed, maintained and installed:

•    Per-router control (每路由器控制).

•    A routing algorithm runs in each and every router; both a forwarding and a routing function are contained within each router.

•    Logically centralized control (逻辑集中式控制).

•    A logically centralized controller computes and distributes the forwarding tables to be used by each and every router.
