12.8 MPLS traffic balancing
ESR routers have a multi-core architecture. One of the first links in processing incoming traffic is the load
balancer daemon (lbd), which performs two main functions:
Distributes the load evenly among all router CPUs.
Detects abnormal situations with high load on some CPUs, and redistributes processing from these
CPUs to less loaded ones.
