Abstract

This paper presents multi-layer IP optical traffic engineering experimental results using our developed IP optical Traffic Engineering (TE) Server, which performs traffic control in corporation with IP routes and optical cross-connects (OXCs) in Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. Multi-layer TE can optimize network resource utilization considering all layers, rather than performing optimization independently for each layer. IP routers and OXCs are managed and operated by the IP optical TE server considering the network resources of both layers. The IP optical TE server computes path routers across different layers and controls them upon request from users and operators. The IP optical TE server dynamically reconfigures an IP network topology that consists of several optical paths in response to traffic demand fluctuations and network failures. The IP optical TE server dynamically reconfigures an IP network topology that consists of several optical paths in response to traffic demand fluctuations and network failures. We successfully performed experiments multi-layer TE.
