10.7. Optical Intradomain Routing

Different standards bodies, such as the IETF, the OIF and the ITU-T, are working on enhancing intradomain routing protocols such as OSPF and IS-IS, for routing and topology discovery in networks that consist of optical or other circuit switches. In this section, we discuss the work in progress in different standards bodies, using OSPF as an example.

Over the last several years, the OSPF routing protocol [Moy98] has been widely deployed throughout the Internet. As discussed in the last chapter, OSPF is a link state routing protocol. OSPF specifies a class of messages called LSAs that allow nodes in the network to update each other about their local links. Five different types of LSAs are defined in OSPF, as described ...
