This article presents information about optical network. The optical networking equipment market has yet to recover, and it is fair to wonder whether this collapse revealed a fundamental limitation of the technology or if this technology can mount a compelling comeback by integrating key features of MPLS networking that have emerged as the de facto standard for packet services creation, management and transport. Traditional, legacy services will be transported through these packet-switched networks as "pseudowires," emulated Layer 1 and 2 services delivered and carried by an JP/MPLS network. With these tenets in mind, network architects are considering whether these features of new networks should be implemented only on routers and switches, the classic packet handlers, or whether the optical network should move beyond pure plumbing and play a role as well. Are optical network engineers just trying to get back in the limelight, or is there real merit to a wedding of optical networking and MPLS? This is where things get more complicated, and more interesting. INSET: From Data--Aware SONET To Packet--Aware Transport.
