“…In addition, many other signaling protocols have also been proposed in the literature [16][17][18][19][20][21][22][23][24][25] . Some of these protocols such as Fast Reservation Protocol (FRP) 25 , fast reservation schemes 18 19 , YESSIR 16 , UNITE 20 and PCC 21 have been designed to achieve low call setup delays by improving the signaling protocols themselves.…”

Signaling protocols in switches are primarily implemented in software for two important reasons. First, signaling protocols are quite complex with many messages, parameters and procedures. Second, signaling protocols are updated frequently requiring a certain amount of flexibility for upgrading field implementations. While these are two good reasons for implementing signaling protocols in software, there is an associated performance penalty. Even with state-ofthe-art processors, software implementations of signaling protocol are rarely capable of handling over 1000 calls/sec. Correspondingly, call setup delays per switch are in the order of milliseconds. Towards improving performance we implemented a signaling protocol in reconfigurable FPGA hardware. Our implementation demonstrates the feasibility of 100x-1000x speedup vis-à-vis software implementations on state-of-the-art processors. The impact of this work can be quite far-reaching by allowing connection-oriented networks to support a variety of new applications, even those with short call holding times.
