Encoding of wavelength converter systems

摘要

An apparatus comprising a path computation element (PCE) configured to perform a path computation using a wavelength converter (WC) pool information based on a dynamic WC pool model, wherein the dynamic WC pool model comprises information regarding WC pool usage state represented using a WC pool usage state vector, and wherein the information regarding WC pool usage state is communicated to the PCE using a WC usage state Type-Length-Value (TLV) that indicates an available WC in a WC pool, a used WC in the WC pool, or both. Also disclosed is a network component comprising at least one processor configured to implement a method comprising receiving a WC usage state TLV comprising information regarding WC pool usage state, establishing a WC pool usage state vector using the information in the WC usage state TLV, and calculating a WC pool connectivity matrix based on the WC usage state vector.

1. An apparatus comprising:
a path computation element (PCE) configured to:
receive a type length value (TLV) that describes properties, structure, and characteristics of a resource pool of a wavelength switched optical network (WSON) node; andperform a routing a and wavelength assignment (RWA) process via the WSON node, wherein the TLV comprises an action field, a reserved field, a length field, and a plurality of resource identifier fields.
