Overview

Local Congestion Mitigation (LCM) is a network optimization technique that detects congestion on a configurable schedule and provides localized traffic diversion recommendations within a domain. It aims to alleviate congestion by rerouting minimal traffic from congested interfaces to alternate paths with sufficient bandwidth, while preserving the original routing paths as much as possible.

Local congestion mitigation

This section describes Local Congestion Mitigation (LCM), a technique for detecting and addressing network congestion on a scheduled basis by providing localized traffic diversion recommendations within a domain.

LCM - device and network requirements

This section outlines the device and network requirements necessary for Local Congestion Mitigation (LCM) to effectively detect, evaluate, and mitigate congestion in your network.

Important considerations when using LCM

This section outlines key recommendations and requirements for configuring and operating LCM.

LCM calculation workflow

This section describes an LCM workflow example, detailing the process from congestion detection to tactical tunnel deployment. It outlines each stage and the calculations involved in optimizing network traffic.

Monitor LCM operations

This section describes LCM dashboards and their roles in monitoring LCM operations.

Temporarily exclude an interface from LCM

This section explains LCM interface exclusions, which allow interfaces to be temporarily removed from LCM mitigation actions.

Mitigate congestion automatically

Use this procedure to enable automated mode for devices that are fully gRPC MSL compliant in the domain.

Example: Mitigate congestion on local interfaces

This section provides an illustrated example of how LCM detects and mitigates interface congestion using TTE SR policies.
