Chapter 25. Dynamic Packet Transport/Spatial Reuse Protocol
Objectives
Describe the background of DPT/SRP.
Explain the DPT/SRP architecture.
Understand bandwidth reuse.
Describe the DPT/SRP packet format.
This chapter introduces Dynamic Packet Transport (DPT) and Spatial Reuse Protocol (SRP). It examines the DPT architecture and SRP's features, including bandwidth optimization, packet priority, the fairness algorithm, and topology discovery. The packet formats of both control and data planes are explained. Finally, this chapter looks at how DPT supports multicast traffic.
Cisco developed DPT technology, based on the MAC-layer SRP, to provide a bandwidth-efficient ring technology optimized for packet transport. It provides scalability of nodes, plug-and-play ...
