This package implements a PLAN interface to ANON, the Active Network Overlay Network . Using this software, the SLRP master communicates routing information to the ANON hub, indicating that it should receive packets all packets from other networks destined for hosts in its network. In this capacity, the SLRP master is an ANON leaf.
The only PLAN function made available by ANON is defaultRoute. This function shadows the SLRP defaultRoute function only on the master node. It has the same semantics as the SLRP defaultRoute function except that in the case that SLRP defaultRoute would have raised the exception NoRouteEntry, ANON defaultRoute returns the address of the ANON hub. This has the hazard that if a PLAN program specifies the hub to be its evalDest, the program will die when it reaches the hub, since it does not have a PLAN evaluation environment: it is only a transport vehicle.
