Co-spanning tree restoration mechanism for metro Ethernet switched networks

Co-spanning tree restoration mechanism for metro Ethernet switched networks Ethernet, a popular technology in IT industry, with high transmission rate, simple maintenance, and compatibility with different types of links was invented for local and small-scale computer networks. However, current spanning tree-based Ethernet protocols do not meet the requirements for metro Ethernet networks in terms of network resilience. One of the most important weaknesses is slow re-convergence time in the event of a link failure when a new spanning tree must be reconstructed to ensure the survivability of networks. In this paper, we propose a co-spanning tree restoration (CSTR) mechanism for metro Ethernet switched networks to handle the link failures. Upon failure of a link on the network, a distributed failure restoration protocol will be activated to reconstruct the damaged spanning tree using a $$co\text {-}tree$$ c o - t r e e link. We explain the details of the protocol, including advertisement tables and fundamental reconfiguration processes. In addition, we propose a simple and effective solution for a double link failure and develop an optional feature to control unnecessary topology changes. The simulated results of CSTR on different network topologies show its features of efficiency and quick recovery. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

Ethernet, a popular technology in IT industry, with high transmission rate, simple maintenance, and compatibility with different types of links was invented for local and small-scale computer networks. However, current spanning tree-based Ethernet protocols do not meet the requirements for metro Ethernet networks in terms of network resilience. One of the most important weaknesses is slow re-convergence time in the event of a link failure when a new spanning tree must be reconstructed to ensure the survivability of networks. In this paper, we propose a co-spanning tree restoration (CSTR) mechanism for metro Ethernet switched networks to handle the link failures. Upon failure of a link on the network, a distributed failure restoration protocol will be activated to reconstruct the damaged spanning tree using a $$co\text {-}tree$$ c o - t r e e link. We explain the details of the protocol, including advertisement tables and fundamental reconfiguration processes. In addition, we propose a simple and effective solution for a double link failure and develop an optional feature to control unnecessary topology changes. The simulated results of CSTR on different network topologies show its features of efficiency and quick recovery.
