Over the last few years, Internet Protocol (IP) networks have made significant progress, allowing to provide voice over IP (VoIP) and other real-time services. The quality of provided real-time services depends on quality parameters of the network (QoS). One of the leading QoS parameters is the survivability of network itself.

Enhancing TCP performance in IP fast reroute
2012 IEEE International Conference on Communications (ICC), 2012IP fast reroute (IPFRR) mechanisms are efficient in providing protection against link or router failure by invoking locally determined backup paths. But in the presence of a transient network failure, the path oscillates between backup and original paths, causing frequent packet out-of-order arrivals at a TCP receiver.

A Lightweight IP Fast Reroute Algorithm with Tunneling
2010 IEEE International Conference on Communications, 2010IP Fast ReRoute (IPFRR) has received increasing attention as a means to effectively shorten traffic disruption under failures. A major approach for IPFRR is to pre-calculate backup paths for nodes and links. Such approach is, however, hard to deploy due to the tremendous computational overhead. Thus, a lightweight IPFRR scheme is desired to effectively

An evaluation of IP-based fast reroute techniques
Proceedings of the 2005 ACM conference on Emerging network experiment and technology - CoNEXT'05, 2005Today, IP-based networks are used to carry all types of traffic, from the traditional best-effort Internet access to traffic with much more stringent requirements such as realtime voice or video services and Virtual Private Networks. Some of those services have strong requirements in terms of restoration time in case of failure. When a link or a router

SD-FAST: A Packet Rerouting Architecture in SDN
2019 15th International Conference on Network and Service Management (CNSM), 2019Communication link failure is common in any network. In Software Defined Network (SDN), protection-based recovery scheme reduces the failure recovery delay by installing alternative routes at the data plane switches. We can deploy Fast Failure Group (FFG) of OpenFlow protocol if a switch has an alternative path towards the destination; otherwise, the ...

On the complexity of computing shortest fast reroute paths
International Congress on Ultra Modern Telecommunications and Control Systems, 2010In order to keep services running despite link or node failure in MPLS networks, RSVP-TE fast reroute (FRR) schemes use precomputed backup label-switched path tunnels for local repair of LSP tunnels. In the event of failure, the redirection of traffic occurs onto backup LSP tunnels that have the same quality of service constraints than original paths ...
