Paper Abstract

A distributed lambda-IX consisting of generalized multi-protocol label switching (GMPLS)-controlled photonic cross connects (PXCs) and GMPLS-controlled Layer-2 switches (L2SWs) is proposed, which enhances the conventional L2-IX features by interacting between GMPLS control plane and L2SW functionalities. The proposed IX enables lambda based connections to be automatically created via PXCs between L2SWs in the IX accommodating an Internet service provider's (ISP's) border routers, which indicates that the high reliable interconnection with low latency can be provided for ISPs, thanks to the PXC technologies and GMPLS functionalities. Furthermore, by interacting with L2SW functionalities such as traffic monitoring and link aggregation, the proposed IX can provide the enhanced functionalities of a dynamic bandwidth modification according to traffic on a real time basis and a fast fault restoration of less than 50 milliseconds.
