# SRP Overview

The Spatial Reuse Protocol (SRP) was developed by Cisco for use with ring-based media. It derives its name from the spatial reuse properties of the packet handling procedure. SRP is the underlying technology used in the Cisco Dynamic Packet Transport (DPT) family of products. DPT is a new generation, transport technology—optimized for packet-based optical transport. This optical transport technology combines the bandwidth-efficient and service-rich capabilities of IP routing with the bandwidth-rich, self-healing capabilities of fiber rings to deliver fundamental cost and functionality advantages over existing solutions.
