Problems solved by technology

When the number of FECs is large, the number of LDP messages published by the LSR is large, which increases the CPU and memory space usage of the LSR, resulting in a decrease in the system performance of the LSR.

Abstract

The embodiment of the invention discloses a message sending and receiving method and device based on label distribution protocol, and relates to communication technological field. The message sending method includes starting up a timer; merging the label distribution protocol messages sent to same direction; and sending the merged message at the fixed time. The invention can make the occupy rate of CPU of LSR and the memory space equal, thereby increasing LSR system performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message sending and receiving technology based on a label distribution protocol. Background technique [0002] At present, Multi-Protocol Label Switching (MPLS for short), as a classified forwarding technology, groups packets with the same forwarding processing method into one class, which is called forward equivalent class (FEC for short). . There are two label distribution methods used in the MPLS: one is Downstream Unsolicited (DU for short); the other is Downstream On Demand (DoD for short). The main difference between the two methods is whether the release of the label mapping is an upstream request or a downstream active release of a label distribution protocol (Label Distribution Protocol, LDP for short) distribution message. Wherein, said upstream and downstream refer to on a Label Switched Path LSP (Label Switched Path, referred to as LSP), along the direction ...
