Protection with Multi-Segments (PROMISE) in Networks with Shared Risk Link Groups (SRLG)∗

چکیده
Shared Risk Link Group (SRLG) has been widely recognized as an important concept in survivable optical networks. The issues of avoiding “traps” (to be defined later) in path determination and maximizing bandwidth sharing, are more challenging in providing shared SRLG protection than in providing shared path protection without considering SRLGs. In this paper, we proposed a novel survivability approach called PROtection using MultIple SEgments (PROMISE) to provide efficient SRLG protection, which can achieve a higher bandwidth efficiency and lower blocking probability at quick speed compared to previous schemes.

A Cost Effective Approach for WDM Network Protection under Critical Duct Constraints
-In this paper, protection strategies of WDM networks are viewed from a cost perspective. The goal is to minimize the network cost while ensuring the network survivability. In WDM networks, multi fibers are kept in a duct and that duct can be treated as a link SRLG (shared risk link group). With the increase in size and number of shared risk link groups, capacity efficiency of shared-path prote...
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 کاملAchieving Diversity in Optical Networks Using Shared Risk Groups
Diverse working and protection paths are used in telecommunication networks to increase survivability and availability in case of faults. In selecting these diverse paths, it is important that the two paths do not share any links that share the same risk. This is done by assigning each link to a Shared Risk Link Group (SRLG). In this paper, we extend this concept to nodes and domains. Diverse p...
متن کاملSpare capacity planning using survivable alternate routing for long-haul WDM networks
Spare capacity planning is to find the minimum amount of spare capacity to be allocated throughout a network so that the network can survive from network component failures. In this paper, the spare capacity planning problem is investigated for long haul wavelength division multiplexing (WDM) networks. A three-step method is developed for solving the problem. First, heuristic approaches are use...
متن کاملGroup shared protection for spare capacity reconfiguration in optical networks
This paper introduces GSP, a group shared protection scheme, for wavelength division multiplexing (WDM) mesh networks with dynamically arrived connection requests. Based on the (M:N) control architecture, GSP has n mutually independent protection groups (PGs), each of which containing N shared risk link groups (SRLG) disjoint working paths protected by M protection paths. Due to the SRLG-disjoi...
