White Paper: Two Paths to Service Class Packet Optical

By Anshu Shrivastava, TMCnet Contributor

The infrastructures of wireline telcos and cable MSOs are evolving and are becoming increasingly IP centric.
However, while shifting to IP protocols, service providers are realizing that SONET-based architectures obstruct the growth of high-capacity Ethernet trunking -- GbE, 10GbE and more. The problem can be solved by creating feeder and distribution infrastructures based either upon next generation optical systems or routers and switches.
The new white paper from intelligent infrastructure provider ECI Telecom says that the combination of its elements in Optics and Carrier Ethernet provides service providers an advantage when it comes to deployment of Ethernet/IP-centric services, and also it enables smooth and easy transition from TDMcentric architectures. The company creates the Converged Service Class Packet Optical solution by the establishment of the 1Net framework, which offers ability to adapt an infrastructure to evolving service needs.
Currently, the service providers are taking two paths to the new infrastructure. One of the paths focuses on resolving high bandwidth connectivity using ROADM (News - Alert)-based optical networks, while the other focuses on packet efficiency by the creation of a network based upon direct interconnection of routers and switches.
The ideal path is the one that allows a service provider to begin with one of the paths and then evolve to a converged service class packet optical feeder and distribution infrastructure. When ROADM optical solution and Carrier Ethernet Switch Router are combined, they provide a Service Class Packet Optical architecture providing seamless convergence of SONET, Optics and Carrier Ethernet.
Click here to view the white paper “Two Paths to Service Class Packet Optical.” The white paper discusses the attributes of ROADM Optical Element and Carrier Ethernet Switch Router. It also talks about the combined efficient IP and Ethernet functionality. Also, it summarizes what are the benefits of ECI’s 1Net Framework; ECI’s XDM Next Generation Optical Platform; and ECI’s SR9700 CESR.
