I like the idea of workstation-based route processors over
forwarding/routing engines because it decouples the complex route
processing s/w environment from the forwarding function.
The economics of complex route processing don't match the economics of big
honking routers and workstations are a better development environment.
The reason to talk about it here is that if we are to move forward in this
direction we need a simple exchange protocol between route server and
forwarding engine to make this happen.
