摘要:
A method for protection of data traffic transmitted over 2-fiber shared protection ring on STM-1/OC-3 interface is provided. Also, the method involves carrying extra traffic in a ring topology for STM-1/OC-3 interface. This is achieved by fixing the granularity to one of ‘VC12/VC11/VC3/VC12-VC3/VC11-VC3’ for the STM-1 interface and to one of ‘VT2/VT1.5/STS-1’ for the OC-3 interface upfront when the protection is configured on the network element.
