Summary :

This paper proposes and performs the primary feasibility evaluation on Flow Attribute Notification Protocol (FANP), which is a protocol between neighbor CSR (Cell Switch Router) nodes for the management of cut-through packet forwarding, in order to apply label switching paradigm. In cut-through packet forwarding with label switching, a router doesn't have to perform conventional IP packet processing for the received packets. FANP indicates the mapping information between a data-link connection and a packet flow to the neighbor node. FANP defines two key procedures, i. e. , one is the VCID Notification Procedure, and the other is the Flow-ID Notification Procedure. The VCID Notification Procedure lets the label switching paradigm over the label swapped data-link, such as ATM link, though the other label switch architecture can not work over the label swapped data-link. The primary evaluation of FANP has been performed using the prototype system and with the actual packet statistics. The result shows that, with a corporate backbone level, the label switch router system with FANP would work well.
