“…(2) Since for real network topologies there is usually more than one way to span the nodes with shortest paths, a set of all the possible shortestpath trees is built for a given source node. (3) All the trees in the set are consecutively considered as the distribution tree for a given source node, and a shortest path tree is chosen as distribution tree if, and only if, the number of wavelengths in the most loaded link of the network is lower than using any other tree in the set.…”

Abstract:A new proposal for an optical packet-routed network based on a distributed router architecture in a WDM network is described. Buffering, scheduling and wavelength assignment functions are carried out in routers located at the edge of the network. The destination address is encoded by a given wavelength and allows wavelength-routing in optical core routers. This approach avoids processing and additional buffering delays in core routers. A low packet loss rate and a low latency are critical parameters to guarantee QoS for a particular class of packets and must be carefully considered when IP traffic is directly transmitted over a photonic network. This network architecture requires new hardware elements and these are discussed including a low-crosstalk, large port-count free-space grating router. INTRODUCTIONWith the projected annual increase of 60% in data traffic [1], solutions are required to combine the advantages of the network packet layer with the high-bandwidth optical transmission in the physical layer. To date the proposed solutions concentrate on current protocols and transmission standards namely ATM and SOH, such as in proposals of IP-over-ATM [2] and packet-over-SOH transmission [3]. Whilst these simplify the protocol stack, limitations in scaling to a large number of routers remain. The advantage of connection-oriented protocols such as ATM is their provision

“…Such an architecture would enable the integration of a high speed Internet service along with native ATM applications while minimizing changes to the widely deployed IP-based applications. A number of proposals for IP/ATM integration have been suggested in the literature, while new schemes continue to appear [13,15,16]. The current proposals include classical IP over ATM [8], LAN emulation [5-61, IP-switching [7], Tag switching, [lO], CSR (Cell Switch Router) [ll], connectionless servers [14], ABR [12], and connectionless virtual networks [l-41. Our approach, referred to as an overlayed connectionless virtual-network [l-41, employs permanent VCs (VPs)…”
