Abstract
In one example, a first Provider Edge (PE) node is configured to communicate with a second PE node through a packet-switched network and with a third PE node through the packet-switched network. The first PE node communicates with a fourth PE node via the second PE node. The fourth PE node is configured to communicate with the second PE node over a working path through a time-division multiplexing transport network. The first PE node exchanges, with the fourth PE node, protection information. Based on exchanging the protection information, the first PE node communicates with the fourth PE node via the third PE node. The fourth PE node is further configured to communicate with the third PE node over a protection path through the time-division multiplexing transport network.
