Abstract
The existing active routing Protocols assume that the active network topology is static or pre-configured. However a dynamic mechanism to route an active Packet according to the network condition is required due to the dynamic characteristic of the active network. As active routing protocols, SLRP and TCOM500 PLAN project have been proposed, but since both of them are based on the assumption of the static topology we can not say that they are dynamic routing protocols in their entirety. Therefore, in this paper, we propose a new active network routing protocol, called AOSPF (Active Open Shortest Path First), which is compatible with the existing IP routing protocol. AOSPF is an extension of OSPF by adding a new LSA (Link State Advertisement) to allow the active network routing. The newly introduced LSA is used to specify whether the corresponding router is an active router or not. and one bit in the OPTION field of an LSA packet is used as the active router indication bit. This way of extending OSPF is similar to the scheme used in the extension of OSPF for multicast, i.e., MOSPF. In this paper, we will present the operation of AOSPF and the way how an active packet is forwarded based on the active network topology information constructed by AOSPF.
