Abstract:
1. A method for managing and transmitting fine granularity services, comprising: adding a time slot of a new fine granularity service to an existing Label Switched Path (LSP) which controls a fine granularity service with the same granularity as that of the new fine granularity service to be established, upon determining that the new fine granularity service shares the same source node and destination node with the existing LSP; establishing a cross-connection for the time slot at every node along the existing LSP; and transmitting the new fine granularity service with the new time slot and the established cross-connection, wherein the process of determining that the new fine granularity service shares the same source node and destination node with the existing LSP comprises: reading the addresses of the source node and the destination node of the new fine granularity service from a request for establishing the new fine granularity service; and determining whether the source node and the destination node of the new service are identical with the source node and the destination node of the existing LSP according to the addresses of the source node and the destination node read from the request; and wherein the process of adding the time slot of the new fine granularity service to an existing LSP comprises: sending an LSP bandwidth update message, which contains the time slot to be occupied by the new fine granularity service, to all nodes along the existing LSP; and setting up, by each node along the existing LSP, a lower order cross-connection corresponding to the new fine granularity service according to the time slot contained in the LSP bandwidth update message.
