Method and system for providing fault recovery using composite transport groups |
摘要 |
An approach is provided for performing fault recovery using composite transport groups (CTGs). A first logical channel is established within a composite transport group, wherein the first logical channel is established over a first link associated with a first service provider to a customer premise equipment (CPE) node configured to transport packets. A second logical channel is established within the composite transport group, wherein the second logical channel is established over a second link associated with a second service provider to an optical node. Packets are received over the first logical channel. Packets are received over the second logical channel if the first logical channel experiences a fault condition, wherein switching to the second logical channel is transparent to the CPE node. |

1. A method comprising:
establishing a composite transport group, including a first channel and a second channel, between a first autonomous system and a second autonomous system, the first autonomous system and the second autonomous system being different from each other; detecting a failure condition of the first channel between the first autonomous system and a first node within the second autonomous system; and rerouting, by the second autonomous system, traffic between the first and second autonomous systems along the second channel between the first autonomous system and a second node within the second autonomous system, wherein the rerouting is transparently performed relative to the first autonomous system. |
