Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] figure 2 It is a flowchart of a message transmission method provided by an embodiment of the present invention. Such as figure 2 As shown, the message transmission method provided by this embodiment includes the following steps:

[0032] Step 201: The BIER entry node encapsulates the characteristic traffic identifier of the scheduled traffic and the planned path information into the BIER message;

[0033] Step 202: The BIER entry node transmits the BIER message according to the planned path information.

[0034] Specifically, for the scheduled traffic of the network, after the BIER ingress node collects the information of all the egress nodes, it encapsulates the...

Abstract

The invention discloses a message transmission method and device, comprising: a BIER entry node encapsulates the characteristic flow identifier and planning path information of predetermined flow into the BIER message; the BIER entry node transmits the BIER message according to the planning path information . The message transmission method and device of the BIER network disclosed by the invention are used to solve the problem that the flow cannot be forwarded through the planned path in the existing BIER technology.

Description

technical field [0001] The present invention relates to the communication field, in particular to a message transmission method and device. Background technique [0002] With the rapid development of software-defined network (SDN, Software Defined Network) technology and network function virtualization (NFV, Network Function Virtualization) in recent years, the controllability of network deployment has become stronger and the control complexity has also increased. come higher. Especially for intermediate networks such as core networks and aggregation networks, in order to adapt to different services and meet different deployment requirements, the control methods are becoming more and more complicated. Especially for multicast applications such as multicast virtual private network (MVPN, Multicast Virtual Private Network) and interactive network television (IPTV), the number of intermediate network node states required increases exponentially. In order to reduce the control...
