Nortel Networks Corp., which today reported a loss for the first quarter of $167 million, has released details of a new technology called Provider Backbone Transport (PBT), which it says will allow service providers to deliver the communication and entertainment services of the future.
According to Nortel, PBT transforms Ethernet technology traditionally restricted to small-scale, local networks into a more reliable, scaleable and deterministic technology making it suitable as the basis for fixed and mobile carrier networks to deliver live video and broadcast, multimedia, broadband data and voice services.
“Ethernet is a pervasive information transport technology due to its simplicity and cost-effectiveness,” said Philippe Morin, president of the company’s Metro Ethernet networks division.
A first version of PBT is already available in the Nortel Metro Ethernet Routing Switch (MERS) 8600, with development also underway to integrate the technology into the Nortel Optical Multiservice Edge (OME) 6500 and other Ethernet-ready platforms.
Stan Hubbard, senior analyst with the research firm Heavy Reading, said PBT has the potential to be a disruptive technology: “Its promise of enabling more manageable and scalable Ethernet that is cost-effective for metro network deployments makes it an attractive complement for service providers with existing MPLS core networks.”
