The boundaries between packet and circuit networks have long disappeared, with many traditional circuit-switched applications such as voice and video now being carried over packet-switched IP/MPLS or Ethernet networks. However, this transition has happened so fast that many OAM functions supported by circuit-switched networks such as SONET/SDH are still(More)
This article examines the technical challenges involved in the delivery of GMPLS, and in particular the challenges in managing these networks. This article focuses first on requirements gathered from customers who are deploying GMPLS in their networks, or will be doing so in the near future. The motivations for these requirements are often based on a(More)
This article describes the first multi-area multiprotocol label switching and generalized MPLS interoperability trial over a reconfigurable optical add/drop multiplexer and optical cross-connect network. The interoperability trial demonstrated the routing of label switched paths over a multi-area GMPLS controlled ROADM/OXC network and the control of(More)
A multi-area MPLS/GMPLS interoperability trial was successfully conducted using various types of network elements from 14 vendors for the first time. The results show that the interior gateway routing protocol based multi-area routing architecture is a promising solution to achieve nationwide deployment of GMPLS networks within a carrier domain.
