Abstract—This paper presents a dynamic service level agreement negotiation mechanism considering intra/inter-domain communications over shared mesh optical networks. The intra-domain negotiation mechanism propagates the link-availability as service level agreement parameters while inter-domain mechanism advertises a proposed service level agreement based traffic engineering constraint called maximum path availability. The paper shows how service level agreement negotiation protocols along with the proposedtraffic engineering metric improvethe performance of priority-aware algorithms.
