An Analytical Approach to Shared Backup Path Provisioning in GMPLS Networks
As GMPLS and its supporting set of protocols develop into a viable control plane for optical networks, an important function that they will need to support will be the restoration and protection function that has been a major feature of legacy optical networks. Several models have been proposed for protection with GMPLS using shared backup paths. This previous work has not investigated the effe...
متن کاملShared Backup Path Protection (SBPP) in Elastic Optical Transport Networks
We consider the share backup path protection (SBPP) and 1+1 protection techniques for CO-OFDM-based elastic optical networks. We develop mixed integer linear programming (MILP) models to minimize required protection capacity and used link spectrum in the network. OCIS codes: (060.4250) Networks; (060.4257) Networks, network survivability
متن کاملUsing Shared Risk Link Groups to enhance backup path computation
To cope quickly with all types of failure risks (link, node and Shared Risk Link Group (SRLG)), each router detecting a failure on an outgoing interface activates locally all the backup paths protecting the primary paths which traverse the failed interface. With the observation that upon a SRLG failure, some active backup paths are inoperative and do not really participate to the recovery (sinc...
متن کاملOptimal Routing with Single Backup Path Protection
Today’s information society relies increasingly on advanced communication networks. This has lead to massive investments in increased communication network capacity. In order to utilize these investments the network operators perform traffic engineering, i.e., route communication in order to maximize the utilization of the capital invested in the communication network. Here we will consider tra...
متن کاملA heuristic algorithm for shared segment protection in mesh WDM networks with limited backup path/segments length
This paper investigates the problem of dynamic survivable lightpath provisioning against single-link failure in optical mesh networks employingwavelength-divisionmultiplexing (WDM).We focus on the special problem of provisioning lightpath requests according to their differentiated protection-switching time, since lightpath may have different protection-switching time requirements. We assume tha...
