Abstract
The growth of demand for transport networks is driven predominantly by the need to provide dedicated pipes for the transport of IP-layer (router-to-router) links. At present, links of IP-layer networks at OC-12 rate (650 Mb/sec) or below route over SONET rings or chains. Links at OC-48 (2.5 Gb/sec) or greater route directly over DWDM systems. Restoration of IP traffic from failures of network components, such as router fabrics/controllers, router cards, DWDM components, or fiber-spans (spans for short), is provided by rerouting the flows through the routers, i.e., within the IP layer. However, with the advent of Optical Cross-Connects (OXCs), with either electrical or optical fabrics, the opportunity exists to provision and restore IP-layer links via the OXC layer (e.g., see Doverspike1).
