Title
Statistical Sharing of Primary and Back-Up Capacity in Survivable Elastic Optical Networks.
Abstract
In this paper, we address the issue of survivability in statistically shared elastic optical networks. Statistical sharing in elastic optical networks is motivated by the recent revolution of software defined optics, where variable data rates, e.g., base rates and peak rates, are supported for a single connection in the network. Our goal is to minimize the blocking of the arriving connection requests, while at the same time maximizing the chance that existing connection requests are able to switch from base rate to peak rate. Furthermore, the base rate of the connection requests should be survivable to any single link failure. In this paper, we introduce an admission control policy and a spectrum management technique that specifies how the spectrum is partitioned and shared for base rate connections, peak rate connections, and back-up capacity. We then propose several survivability schemes in order to provide dedicated protection to the base rate of the connection requests. We evaluate our proposed schemes through simulations, seeking to find an optimum tradeoff between the base rate and the peak rate blocking.
