A study group in the ITU is working on a very similar problem that we are in regards to user control of lightpaths. They see the primary market between carriers, where for example, a CLEC may want to extend its network by acquiring a layer 1 VPN from another carrier. In the Y.1312 architecture the network elements are partitioned so that the CLEC can incorporate the VPN within their network and create daughter VPNs as well as incorporate routing, topology and alarm and control information from the carrier such that VPN is a seamless extension of the CLEC’s network.
The Y.1312 is a very high level architectural document but I think you will find it incorporates many of the ideas we have been talking about within CA*net 4 network. The CA*net 4 implementation allows regional networks and high end researcher to build national or international IP routed networks that are an extension of their campus or regional network. For example, the community of high energy physics researchers could build an “ad hoc” IP routed network that is dedicated to their specific application needs and is deployed in parallel with more traditional hierarchical IP networks. The net effect is an increase in the BGP mesh such that the high energy physics sites have direct BGP single hop peering as well as a normal multi-hop IP route through their normal network connections.
With Y.1312 condominium wavelength networks like the National LambdaRail and CA*net 4 can be partitioned into many application or discipline specific IP routed networks. The Y.1312 document is available from the ITU at: www.itu.int/itudoc/itu-t/aap/sg13aap/recaap/y1312
