摘要
A method and device are used for realizing primary-backup protective of low order cross apparatus of SDH low order virtual container deploy based on switching network. The method includes distributing multicast ID as the destination address of code flow of high order virtual container, wherein the high order virtual container includes SDH low order virtual container to be deployed and the multicast ID is directed respectively to the port connected to the two or more than two low order cross apparatuses in switching network; closing the connected channel between the switching network and said backup low order cross apparatus; and opening the connected channel between the switching network and one of the backup low order cross apparatus when the primary low order cross apparatus fails. The method can efficiently perform primary-backup rearrangement when SDH low order virtual container is deployed based on switching network.
