A fast rerouting scheme for OSPF/IS-IS networks

Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat. No.04EX969), 2005
Most current backbone networks use link-state protocol, OSPF or IS-IS, as their intra-domain routing protocol. Link-state protocols perform global routing table update to route around the failures. It usually takes seconds. As real-time applications like VoIP emerge in recent years, there is a requirement for a fast rerouting mechanism to route around ...

IP fast reroute with failure inferencing

Proceedings of the 2007 SIGCOMM workshop on Internet network management, 2007
Five nines availability is being expected from IP networks due to the growing popularity of IP telephony and the increasing usage of the Internet for mission-critical applications. This necessitates enhancing the resiliency of IP networks against transient failures that are observed to happen relatively frequently even in well-managed networks. Towards

A Fast Reroute Scheme for IP Multicast

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
We propose a fast reroute scheme for the single link failure protection of IP multicast network. A multicast network connects nodes as a spanning tree, which is vulnerable to link failures. Our scheme uses ring topologies to ensure a backup path always exists to any single link failure and only a few nodes in the neighborhood of the failed link have to

Evolution of IP Fast-Reroute Strategies

2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM), 2018
Due 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.

Evaluation of IP Fast Reroute Proposals

2007 2nd International Conference on Communication Systems Software and Middleware, 2007
With the increasing demand for low-latency applications in the Internet, the slow convergence of the existing routing protocols is a growing concern. A number of IP fast reroute mechanisms have been developed by the IETF to address the issue. The goal of the IPFRR mechanisms is to activate alternate routing paths which avoid micro loops under node or ...

Review of Fast ReRoute solutions

2020 18th International Conference on Emerging eLearning Technologies and Applications (ICETA), 2020
The Fast ReRoute (FRR) is an area that addresses issues of network recovery in the event of crucial devices or line failures in the network. During the event of a failure in the ISP network, the process of network convergence starts. This process may last unpredictable time and traffic affected by the failure may be inevitably lost. FRR mechanisms work

FBR: Dynamic Memory-Aware Fast Rerouting

2022 IEEE 11th International Conference on Cloud Networking (CloudNet), 2022
Modern internet communication networks, such as MPLS networks, provide fast rerouting mechanisms in the data plane in order to quickly react to link failures and hence become more dependable. However, fast rerouting requires additional memory for the conditional failover rules--a scarce and expensive resource. We initiate the study of memory-aware fast

A Fast Reroute Mechanism for RIP Protocol

2009 Pacific-Asia Conference on Circuits, Communications and Systems, 2009
Aiming at the RIP (Routing Information Protocol) can’t dealing with network failures effectively, causing significant forwarding discontinuity after a failure. The drawback with this protocol is that it need to trade off routing stability and forwarding continuity.

Optimizing the QoS Performance of Fast Rerouting

2009 Ninth International Conference on Hybrid Intelligent Systems, 2009
A fast rerouting scheme is proposed to guarantee the QoS performance of rerouted path when handling link and node failures. The new scheme is based on deflection routing mechanism and improves on two aspects: first, it can promptly handle single node failure as well as single link failure, second, QoS metric is taken into accounted when calculating ...

IP fast rerouting for multi-link failures

IEEE INFOCOM 2014 - IEEE Conference on Computer Communications, 2014
IP fast reroute methods are used to recover packets in the data plane upon link failures. Previous work provided methods that guarantee failure recovery from at most two-link failures. We develop an IP fast reroute method that employs rooted arc-disjoint spanning trees to guarantee recovery from up to $(k-1)$ link failures in a $k$ -edge ...
