Local protection reroutes the traffic rapidly around the failure, so this mechanism is called “Fast Reroute (FRR)”. In local protection the aim is not using another path

RFC 4090 RSVP-TE Fast Reroute May 2005 When a failure occurs along the protected LSP, the PLR redirects traffic onto the local detour. For instance, if the link [R2->R3] fails in Example 1, R2 will switch traffic received from R1 onto the protected LSP along link [R2->R7], using the label received when R2 created the detour.

RIS 2016-06-01 Fast Reroute Extensions to RSVP-TE for LSP Tunnels (RFC 4090, May 2005) TI LFA Fast ReRoute can now protect from link, node, or SRLG failure to increase network availability significantly. Fast Reroute was also tested on the Cisco site which was subsequently disconnected by means of a serial link between routers P2 and P3. Every single second was sent an ICMP message from PC2 to PC1. Because only two ICMP messages were lost, the convergence time of Fast Reroute was just 2 seconds, which can be seen in Figure 11.

LFAs and rLFAs are simple and require no addi-tional forwarding entries but cannot protect against all single link failures. Feature vSphere 6.5 vSphere 6.7 vSphere 7; Kubernetes, VMware Tanzu Runtime and Hybrid Infrastructure Services • (VMware Cloud Foundation) vMotion (storage, cross-vSwitch, cross-vCenter, long-distance, cross-cloud hot and cold) Fast reroute (FRR) mechanisms are widely used in IP and MPLS networks by computing the recovery path before a failure occurs. Sub-second service restoration is a key requirement for MPLS and native IP-based network service providers.

Due to the time limit, we have not transplanted the design to the NetFPGA’s standard TCAM based output port 2019-11-12 •IP Fast Reroute refers to the set of technologies aiming to provide fast rerouting capability using pure IP forwarding and routing paradigm •Similar service as delivered by MPLS when MPLS-TE-FRR is deployed •Both “families” of FRR technologies (IP and MPLS) need to address the Microloop issue Not covered on this presentation Fast reroute is a MPLS (Multiprotocol Label Switching) and IP resiliency technology to provide fast traffic recovery upon link or router failures for mission critical services. Upon any single link or node failures, it could be able to recover impacted traffic flows in the level of 50 ms.
