IP Fast Reroute Using Relaxed MRC
نویسندگان
چکیده
We demonstrate IP fast reroute using a recently proposed method called Relaxed Multiple Routing Configurations. The demo comprises a small network of Linux routers, where the effect of network failures can be observed on real-time applications with and without IP fast reroute in effect.

A Comparison between Two Post-Failure Load Distribution Techniques with Multiple Routing Configurations
When a link fails in an IP network, the network re-converges to redirect the traffic away from the failed link. IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post f...
متن کاملIP Fast Reroute in Networks with Shared Risk Links
IP fast reroute is a mechanism that is used to reroute packets around a failed link as soon as the link fails. Most of the IP fast reroute mechanisms, that have been proposed so far, focus on single or dual link failures but can not handle Shared Risk Link Group (SRLG) failures when several links fail at the same time because of some common underlying component failure. Furthermore, most of cur...
متن کاملIP Fast ReRoute: Lightweight Not-Via
In order for IP to become a fulledged carrier-grade transport technology, a native IP failure-recovery scheme is necessary that can correct failures in the order of milliseconds. IP Fast ReRoute (IPFRR) intends to ll this gap, providing fast, local and proactive handling of failures right in the IP layer. Building on experiences and extensive measurement results collected with a prototype imple...
متن کاملInternet Engineering Task Force (ietf) Benchmarking Terminology for Protection Performance
This document provides common terminology and metrics for benchmarking the performance of sub-IP layer protection mechanisms. The performance benchmarks are measured at the IP layer; protection may be provided at the sub-IP layer. The benchmarks and terminology can be applied in methodology documents for different sub-IP layer protection mechanisms such as Automatic Protection Switching (APS), ...
متن کاملLoop-free alternates and not-via addresses: A proper combination for IP fast reroute?
The IETF currently discusses fast reroute mechanisms for IP networks (IP FRR). IP FRR accelerates the recovery in case of network element failures and avoids micro-loops during re-convergence. Several mechanisms are proposed. Loop-free alternates (LFAs) are simple but cannot cover all single link and node failures. Not-via addresses can protect against these failures but are more complex, in pa...
