[Los Angeles, US,15 March , 2011] Huawei, a leader in providing next-generation telecommunications network solutions for operators around the world, today released the OBTN (Optical Burst Transport Network) prototype which utilizes burst technology to realize optical layer packet switching. The successful development of this prototype highly accelerates the evolution towards an all-optical switching network.
OBTN is an all-optical switching technology led by Huawei. It enables convergence of Layer 0 (optical layer), Layer 1 (electrical physical layer) and Layer 2 (link layer), reducing the total OAM of a network. Compared with previous packet add/drop schemes, OBTN is compatible with current WDM wavelength-switching networks and is able to offer both sub-wavelength and wavelength granularity aggregation. By attaching optical control labels to each optical packet, sub-wavelength add/drop is realized based on all-optical processing.
“The OBTN prototype is a significant milestone in the progress towards the all optical network. Huawei views strategic investment in advanced transport technologies as a key foundation to solve its customers’ challenges as networks scale in bandwidth and transition to packet centric topologies,” said Changtian Cai, President of Huawei Transport Network.
