Abstract :
Internet operators and ISP providers have traditionally designed network resources following an over-planning policy, on attempts to maintain a desired grade of service and network availability, regardless of network failures. This work presents a comparative study of two resilience mechanisms in the design of optical networks either based on optical burst switching (OBS) or optical circuit switching (OCS): the M:N protection scheme with dedicated backup channels. It is further analysed and discussed the benefits and disadvantages of such mechanism based on an analytical model
