As optical networking deployments increase, multi-domain provisioning and survivability are becoming major concerns. A key challenge in multi-domain survivability is the scalability problem. To address this concern, various solutions have already been proposed based upon topology aggregation schemes. However, these mechanisms do not scale well with increasing domain counts and further investigation...
As optical network deployments increase, multidomain survivability is becoming major concern. To address this issue, in this paper we propose a novel graph partitioning technique for improved protection scalability in such networks. To demonstrate the efficiency of our method, we also extend the p-cycle concept to expanded multi-domain settings. Overall simulation results show the efficiency of our...
Survivability becomes an important issue in optical networks due to the huge bandwidth offered by optical technology. Many works have studied network survivability. The majority of these works are typically destined to single-domain. In this work we address the survivability in multidomain optical networks. This paper provides a classification of the existing protection solutions proposed for multi-domain...
The major challenge of p-cycle network design resides in finding an optimal set of p-cycles protecting the network for a given working capacity. Existing solutions (exact and heuristic approaches), for solving the problem, find the set of p-cycles protecting the network through two steps: one step for generating candidate p-cycles and a second step for selecting the efficient ones. In this paper,...
