METHOD AND APPARATUS FOR CONGESTION SIGNALLING FOR MPLS NETWORKS

摘要

Methods and apparatuses for congestion signaling for MPLS networks have been disclosed. A method for use by a transit node on a LSP within an MPLS network comprises: generating a congestion notification in response to a congestion occurring during transmission of packets; and transmitting the congestion notification to an egress node on the LSP. Further, a method for use by an egress node on a LSP within an MPLS network comprises: obtaining a congestion notification, wherein the congestion occurs during transmission of packets; and handling the congestion notification. Thus, a congestion signaling mechanism in MPLS networks are introduced.
