Abstract

A more flexible routing of better performance can be achieved in multilayer networks when the controllers of different network layers are "peering" instead of "overlaying", i.e., instead of the simple overlay model the peer interconnection or the vertically integrated model is used, and Label Switched Paths are searched in a Wavelength Graph that represents the network state very accurately. However, routing in "Peer network" does not only require large databases for storing the Wavelength Graph and complex path-search algorithms, it also increases the load of control channels, as more link state changes must be advertised. Much of the link state information is, however, redundant as the state changes are not independent. In this paper we propose a method for topology information advertisement and maintenance to significantly reduce the amount of control messages without deteriorating the quality of routing.
