Disruptive all-optical switching and ultra-long reach WDM transmission technologies enable all-optical networks without OEO conversion along paths that can span thousands of kilometers. Coupled with advances in automatic discovery, distributed routing and signaling mechanisms, the next generation all-optical intelligent networks (AOIN) has been one of the most promising technology innovations. Based on the particular PXC structure, this paper addresses in detail the process of AND in AOIN, which includes three major periods. As far as the simulation is concerned, a GMPLS-based software platform built by us can demonstrate the AOIN performance, and a meaningful result is derived when comparing the speeds of AND under different monitoring schemes.
In this paper, according to the ITU-T recommendation G.8080, we present a novel architecture of RC based on the extended GMPLS, which consists of interface component, OSPF-TE component, route computation component and routing information database. The RC is emulated in the ASON simulation software developed by us, where the OSPF is extended as the routing protocol and GMPLS RSVP-TE is adopted as signalling protocol. In the simulation, the RWA scheme, the fixed shortest path routing way and first fit wavelength algorithm, is used. The simulation results of RC have been presented in terms of flooding time (FT), flooding overhead (FO) and route computing time. The FT and FO just have a very little change under different traffic load, which indicates that re-flooding is rare and the RC works efficiently.
