ABSTRACT
Generalized multiprotocol label switching,
also referred to as multiprotocol lambda switching,
supports not only devices that perform pack-et
switching, but also those that perform
switching in the time, wavelength, and space
domains. The development of GMPLS requires
modifications to current signaling and routing
protocols. It has also triggered the development
of new protocols such as the Link Management
Protocol. In this article, we present the traffic
engineering enhancements to the Open Shortest
Path First Internet routing protocol [1] and IS-IS
Intradomain Routing Protocol ([2, 3]), two
popular routing protocols, to support GMPLS.
We present the concepts of generalized inter-faces,
label-switched path hierarchy, and link
bundling intended to improve GMPLS scalability.
We also discuss the link management protocol
which can be used to make the underlying
links more manageable.
