Expand description

A routing algorithm to provide candidate routes when the Router requires. It may store/use information in the RoutingInfo. A Routing does not receive information about the state of buffers or similar. Such a mechanism should be given as a VirtualChannelPolicy.

Required methods

Compute the list of allowed exits.

Initialize the routing info of the packet. Called when the first phit of the packet leaves the server and enters a router.

Updates the routing info of the packet. Called when the first phit of the packet leaves a router and enters another router. Values are of the router being entered into.

Prepares the routing to be utilized. Perhaps by precomputing routing tables.

To be called by the router when one of the candidates is requested.

To optionally write routing statistics into the simulation output.

Clears all collected statistics
