Abstract:
1. A method for providing an internal topology of a node within a network, comprising: determining asymmetric connections between receiver transmitter pairs (RTPs) in a network node; the RTPs each comprising intra RTP connections between internal RTP components, the intra RTP connections having a higher speed than the asymmetric connections between the RTPs, wherein the internal RTP components comprise an optical receiver and an optical transmitter for interfacing with a wavelength division multiplex (WDM) system; determining an intranode connectivity between the RTPs based on the asymmetric connections; distributing a model of the node indicative of the intranode connectivity to a disparate node in a network with the node; and using the model at the disparate node in determining a routing path through the network.
