ABSTRACT:
This application proposes a solution that makes access to the Optical Link State (OLS) information more efficient for use by upper level applications. Applications are independent of underlying routing protocols. This solution applies to all Link State based IGP protocols with the extension to optical networks, including OSPF and IS-IS.
