Abstract
A method and apparatus of allowing client roaming between gateways of a wireless mesh network is disclosed. The gateways are connected through a layer 3 network to an aggregation router. The method includes a first gateway sending a first route update to the aggregation router when a client joins a first cluster of the first gateway, the first gateway aging the route, and a second gateway sending a second route update to the aggregation router when the client roams to a second cluster of the second gateway.

A method of a wireless mesh network gateway aging a client route, the wireless mesh network gateway being connected to an aggregation router, comprising:
- the mesh network gateway assigning a cost function corresponding with a client route an initial value when the mesh network gateway installs the client route;
- the mesh network gateway aging the client route by incrementing the cost function over time;
- the mesh network gateway updating the aggregation router with the cost function every time the cost function changes value.
A method of allowing client roaming between gateways of a wireless mesh network, the gateways being connected to an aggregation router across a layer three network through tunnels, the method comprising:
- a first gateway sending a first route update of a first route to the aggregation router when a client joins a first cluster of the first gateway;
- the first gateway aging the first route;
- a second gateway sending a second route update to the aggregation router when the client roams to a second cluster of the second gateway.
A computer program operable on a processing unit of a mesh network gateway, the gateway connected to an aggregation router through a layer three network, the computer program executing a method comprising:
- assigning a cost function corresponding with a BGP client route an initial value when the mesh network gateway installs a client route;
- aging the BGP client route by incrementing the cost function over time;
- updating the aggregation router with the cost function every time the cost function changes value.
