mpls point of local repair (PLR) and merge point(MP),MPLS Recovery

Fast Reroute Protection Types Both One-to-One and Facility Backup can protect different network elements. And these can be achieved by two ways: – Node Protection : Protect against the failure of the next downstream router. The upstream router before the failure node establishes a protection tunnel that goes around the failed next downstream router. This […]

mpls point of local repair (PLR) and merge point(MP),MPLS Recovery

MPLS Local Protection (Fast Reroute) The goal of the protection is minimizing the down time. To do this, protection must be done near to the failure. Local protection does this. By doing this types of protection, it avoids using entire path protection. Local protection reroutes the traffic rapidly around the failure, so this mechanism is […]

Strict Path, primary path, secondary path,MPLS Recovery

Path Diversity in Secondary Paths As we say in the following articles, while using Secondary LSP-Paths, sharing links between Primary and Secondary LSP-Paths must be avoided. We can say this term “Path Diversity”. There are some methods to achieve Path Diversity. These methods are: – Using Full Strict hop LSP-Paths – Admin Groups – Shared […]

mpls end-to-end protection primary path and secondary path,MPLS Recovery

Protection Types There are some different types traffic protections. In general we can divide these types into two groups. End-to-end Protection and Local Protection. End-to-end Protection is using Secundary LSP-Paths as a backup, beside Primary LSP-Path. Local Protection is the mostly used MPLS recovery mechanism, MPLS FRR (Fast Reroute). End-to-End Protection (Secondary Paths) In this […]

MPLS Protection and Restoration, MPLS Recovery As you know, we can prioritize some of the traffic with MPLS-TE because of their nature. The high priority can be given to the voice and video traffic. Because they are fragile traffic types. During a failure normally these real time traffics send first and then the others. Like […]
