Abstract
Official abstract text for this publication.
A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for in-band protection switch signaling in a communication system, the communication system arranged as a point-to-multipoint tree, the point-to-multipoint tree including a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link, the method comprising: transferring data through a current link of the point-to-multipoint tree, the current link being one of the working link and the protection lin…
