Routing scenarios

This page contains a collection of routing scenarios which all routing protocol changes have to go through to estimate its impact.

Best route

Asymmetric link

The nodes A, B and C are connected via asymmetric links - every node has a good transmit connection to one neighbor and a good receiving connection from the other. The protocol has to detect that the best neighbor towards any destination is the one it rarely gets routing information from.

Asymmetric path

Node A and B are connected via multiple paths with different characteristics: a short asymmetric path and a long path without packet loss. The protocol should choose the long path for traffic traveling from A to B and the short path in the opposite direction.

Convergence speed

A and B have 2 possible paths to communicate with each other. One of the nodes that is part of the currently used path dies or one of the links breaks down and the protocol needs to detect the unavailability of the path to switch as fast as possible to the other one.

Mobility

While A is moving through the mesh the route between A and B shall recover as fast as possible.
