Problems solved by technology

Among them, the physical link delay is determined based on the transmission distance between the message sending device and the message receiving device. The transmission distance between the message sending device and the message receiving device cannot be changed, so it is difficult to reduce Small physical link delay to reduce message transmission delay

Embodiment Construction

[0040] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0041] The message processing method provided by this application can be applied to figure 1 The MPLS network architecture shown, figure 1 The nodes of the shown MPLS network can be logically divided into label edge routers (Label Switching Edge Router, LER) and label switching routers (Label Switching Router, LSR). Among them, the LER at the entrance can provide the mapping between the equivalent forwarding class (Forwarding Equivalence Class, FEC) and the label, the LER at the exit provides the function of removing the label, and the LSR is the core switch of the MPLS network, which provides label switching (Label Swapping) and label distribution functions, such as encapsulating MPLS labels for packets.

[0042] The connection between nodes in the MPLS network is called a label switching path (Label Switching Path, LSP). Each ...

Abstract

The invention discloses a message processing method, device and system, which realize decrease of a transmission time delay of each hop of physical device on a label switching path so as to reduce a message transmission time delay. In the message processing method, a first label switching router (LSR) receives a first multi-protocol label switching (MPLS) message; the first LSR carries out fragmentation processing on the first MPLS message to obtain a first MPLS fragmented message; and the first LSR sends the first MPLS fragmented message to a second LSR, wherein the first MPLS fragmented message comprises an MPLS label stack and a first MPLS fragmented message header, the MPLS label stack comprises a first label set and a second label set, and the first MPLS fragmented message header is encapsulated between the first label set and the second label set; a stack top label is a synonymous label, and a bit, in the synonymous label, representing a stack bottom identifier is set to be 1; and the first MPLS fragmented message header comprises a fragmented message sequence identifier.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a message processing method, device and system. Background technique [0002] How to reduce the packet transmission delay has been a research subject in the industry. [0003] At present, a multi-protocol label switching (Multi-Protocol Label Switching, MPLS) network is a system for fast data packet switching and routing. For a message transmitted through the MPLS network, a label switching router (LSR) will encapsulate an MPLS label for the message according to the forwarding processing method of the message, and then forward the message in the MPLS network. In the packet forwarding in the MPLS network, the packets with the same forwarding processing mode are classified into one class, which is called a forwarding equivalence class (Forwarding Equivalence Class, FEC). Groups with the same FEC will be treated exactly the same in the MPLS network. [0004] H...
