Abstract

The two complementary approaches for Wavelength division multiplexing (WDM) upgrading Resilient packet ring (RPR), which is designed to provide fast recovery from a single link or node failure through protection mechanisms that ensure high availability and reliability, are discussed. The first approach deploys WDM on the fiber ring and does not require any additional fiber infrastructure. The second approach expands the RPR network by an additional single-hop star WDM subnetwork, which requires additional fibers. WDM rings provide an increased capacity by deploying multiple wavelengths on each fiber. The advance direction for WDM upgrading single-channel RPR networks are hybrid WDM upgrades that deploy WDM on both the peripheral and star subnetwork. Operating a few additional wavelength channels on the peripheral fiber ring will enable the efficient transport of the multicast and broadcast traffic on the ring.
