A Service-Transparent and Self-Organized Optical Network Architecture

In this paper, a new service oriented networking paradigm is presented, where network nodes (peers) are self- organized into individual service entities. The key idea relies on the overlay approach, where there exists a virtual service plane, fragmented into self-organized and self-managed entities called islands of service transparency. The islands are formed in an upstream, ad-hoc mode from the non-networking resources (i.e VoD, grid server, etc) towards all ingress routers of the network, using link state advertisements and multi-cost path selection algorithms (i.e residual bandwidth, server capacity, storage, etc). Organization and re-organization of nodes around non-network resources is transparent to end-users, and thus any request within a specific service island is transparently routed to the island´s resource for execution. A service proxy is commissioned to resolve service addresses and service attributes to QoS metrics. In this paper, we present the main notations and metrics of the proposed architecture as well as node behavior and potential GMPLS extensions for implementation issues.
