FEBRUARY 5, 2008 -- TelefÃ³nica I+D, the research and development arm of the TelefÃ³nica Group, says it has successfully completed tests on the performance and reliability of Nortel's (search for Nortel) Provider Backbone Bridges (search for PBB) and Provider Backbone Transport (search for PBT) carrier Ethernet equipment.
The tests, using PBB and PBT to support video and other high-bandwidth mobile data services, were conducted at the TelefÃ³nica I+D laboratory in Madrid, Spain.
Nortel says itsÂ PBB and PBTÂ technology is using industry-standard Ethernet to drive a radical change in the economics of carrier networks by adding carrier-grade reliability and ease of service management to the simplicity and cost-effectiveness of Ethernet. The equipment tested by TelefÃ³nica I+D is aimed at enabling service providers to address the growth of high-bandwidth video and data applications in their metro networks by making Ethernet an option for any service they wish to offer. These include next-generation services such as triple and quadruple play, wireless video and data, and Ethernet business connectivity.
"Innovation is TelefÃ³nica I+D's reason for being," notes Enrique Algaba, vice president of TelefÃ³nica I+D. "Industry consolidation and the growing demand from business and consumers for more true broadband services means we have to be adept at looking for solutions that are innovative and cost-effective. Nortel's Ethernet-based PBT and PBB innovations have enabled us to test how service providers can use these technologies to maximize network efficiencies and deliver more true broadband services such as VoIP, video, and TV," he says.
The tests were conducted as part of a European Information and Communication Technology (ICT) program under the EUREKA (pan-European network for market-oriented and industrial research and development) framework, whereby TelefÃ³nica I+DÂ evaluates different networking technologies for enhancing service offerings and reducing customer costs.
"With PBB and PBT, Ethernet can now meet the market demand for carrier applications such as the triple play of high-speed Internet access, television, and VoIP over a single broadband connection as well as wireless backhaul and Ethernet connectivity services, offering carriers a cost-effective, simple option to more complex and costly transport technology such as MPLS," explains Fernando Valdivielso Delgado, vice president, TelefÃ³nica global account, Nortel. "The successful tests conducted by TelefÃ³nica I+D are another step in the continuing worldwide development and adoption of carrier-grade Ethernet to help capitalize on the era of hyper-connectivity where everything that can be connected to the network, will be."
The tests at TelefÃ³nica I+D included the enabling of deterministic point-to-point Ethernet transport tunnels with SONET/SDH-like management characteristics to show how Nortel's PBB and PBT technology could be used to support wireless backhaul. Nortel says the test was based on the itsÂ Metro Ethernet Routing Switch 8600,Â which leverages the latest carrier Ethernet innovations, including PBB and PBT. PBT is currently progressing through industry standardization within the IEEE 802.1, where it is known as IEEE 802.1Qay (Provider Backbone Bridge-Traffic Engineering).
Nortel'sÂ Metro Ethernet ManagerÂ was also utilized to provide end-to-end service and PBT trunk provisioning, as well as enhanced fault management and troubleshooting capabilities for the network.
