Provisioning And Management Of Interdomain Connections In Optical Networks: A Service Oriented Architecture-based Approach

Provisioning of interdomain connections has been a constant challenge for providers. Clients (e.g. access networks) are asking for services that span across multiple different domains and each domain has its local constraints (policies) that must be analyzed before accepting an end-to-end (e2e) connection. In this paper we present a Service Oriented Architecture-based approach by which basic services are modeled and composed to create more complex services. Such approach considers the establishment of e2e interdomain connections in optical networks. The architecture we present here consists of a virtual topology service, an end-to-end connection service and an end-to-end negotiation service. All of them were implemented using the Web services technology. © 2006 IEEE.Carvalho, C., Verdi, F.L., Madeira, E., Magalhães, M., Policy-based Fault Management for Integrating IP over Optical Networks.
