Performance Evaluation of a Bufferless OBS/OPS Network With 1+1 Path Protection
2015 (English)In: IEEE Photonics Technology Letters, ISSN 1041-1135, E-ISSN 1941-0174, Vol. 27, no 20, 2115-2118 p.Article in journal (Refereed) Published
In optical burst/packet switched (OBS/OPS) networks, bursts/packets may be dropped because of equipment failures. A widely used mechanism to protect a connection from a single-trunk-failure event is 1 + 1 path protection. We consider a bufferless OBS/OPS network with two types of users: 1) premium (that receive 1 + 1 protection service) and 2) regular (that do not receive such a service). We propose a fast and accurate approximation to evaluate the performance of such OBS/OPS network. The accuracy and scalability of the approximation and the effect of the proportion of the premium users in the network are discussed.
