New Carrier Ethernet technology from Nokia Siemens Networks

Nokia Siemens Networks presented its network solutions and switches for Carrier Ethernet technology that support Provider Backbone Bridging Traffic Engineering (PBB-TE) at NXTcomm 2007 in Chicago this week. The Institute of Electrical and Electronics Engineers (IEEE) is currently ratifying this standard.

Provider Backbone Bridging Traffic Engineering (PBB-TE) is the new connection-oriented technology for Carrier Ethernet networks. As carriers increasingly look to offer end-to-end Ethernet services, PBB-TE offers a new way for them to optimize their packet transport, meaning they can use their networks more efficiently and cost effectively. PBB-TE lets service providers reap the full benefits of Carrier Ethernet — carrier-grade reliability, manageability, security and scalability — in their large telecommunications networks.

“Cutting costs is right at the top of our customers’ to-do lists. Thanks to our Ethernet products with PBB-TE, we will be able to offer a low-cost alternative that is fully carrier-grade,” said Bernd Schumacher, head of IP/Transport, Nokia Siemens Networks.

Nokia Siemens Networks has cooperated with British Telecom to develop and deploy PBB-TE products for the carrier’s new 21st Century Network.
