Fast Reroute in Hybrid Segment Routing Network
2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC), 2020We consider a hybrid segment routing (SR) network consisting of both IP routers and SR routers. We focus on exploiting the source routing capability of SR to enhance the performance of IP fast reroute. In particular, an IP router detects a local link failure, it can immediately reroute the affected packets by tunneling them to a SR router.

A framework for fast IP rerouting
International Conference on Information Communication and Embedded Systems (ICICES2014), 2014As the Internet takes an increasingly central role in day to day communications infrastructure, the slow convergence of routing protocols after a network failure becomes a growing problem. To assure fast recovery from link and node failures in IP networks, it presents a new recovery scheme called Multiple Routing Configurations (MRC).

Evolution of IP Fast-Reroute Strategies
2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM), 2018Due to increasing requirements related to quality of service and network dependability, several IP Fast-Reroute mechanisms have been designed to limit the consequences of one or more simultaneous failures in routed computer and communication networks.

After the failure of a network node or a link, a period of impaired connectivity is experienced until the network reconverges. During this period, specific destinations are not reachable, causing issues specifically with critical and time-sensitive services such as Voice over IP.

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.

Effectiveness of Link Cost Optimization for IP Rerouting and IP Fast Reroute
2010In this paper, we bring together resilience analysis and routing optimization for IP-based intra-domain networks. When link, node, or multiple failures occur, traffic is rerouted which increases the link load on backup paths and possibly causes congestion. Resilience analysis detects the risk of overload situations a priori based on a large set of most

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
