Problems solved by technology

However, in the process of communication between the two sites, if there is a link failure, path congestion, etc., the site that fails to send the message needs to wait until the timeout has not received the response message before it knows that the message has not been sent successfully, and then triggers re-election. If the site that fails to send the message is site 2, then site 1 needs to reselect the path before site 2 can continue to send the message, which causes serious service delay

Embodiment 1

[0072] Figure 5 It is a schematic flowchart of a service flow processing method provided in this application. like Figure 5 As shown, the method may include the following steps:

[0073] Step 501: the second device sends a first packet to the first device. The first message includes a master scheduling identifier, which is used to identify that the second device has the right to select a path.

[0074] Step 502: The first device receives the first packet from the second device, and determines a first path adopted by the transmission of the first packet.

[0075] Step 503: The first device sends a second packet to the second device using the first path, the second packet includes a follow-up identifier, and the follow-up identifier is used to identify that the first device adopts a transmission selected by another device other than the first device route to send packets.

[0076] In this embodiment of the application, the second device, as the master scheduler, has the r...

Embodiment 2

[0117] Figure 8 It is a schematic flowchart of another service flow processing method provided in this application. like Figure 6 As shown, the method may include the following steps:

[0118] Step 801: the second device sends a first packet to the first device. The first message includes a follow-up identifier, and the follow-up identifier is used to identify that the second device uses the transmission path selected by another device other than the second device to send the message.

[0119] Step 802: The first device receives a first message from the second device.

[0120] Step 803: The first device determines the first path for sending the second packet according to the routing policy.

[0121] Step 804: The first device sends a second packet to the second device by using the first path, the second packet includes a master dispatcher identifier, and the master dispatcher identifier is used to identify that the first device has the right to select a path.

Abstract

The application discloses a message transmission method and device. The method includes: the first device receives a first message from the second device, the first message includes a master scheduling identifier, and the master dispatching identifier is used to identify that the second device has the right to select a path; the first device determines that the first message The first path adopted by the transmission; the first device uses the first path to send a second message to the second device, the second message includes a follow-up identifier, and the follow-up identifier is used to identify that the first device adopts a second message other than the first device A transmission path selected by the device to send the message. When the second device communicates with the first device, the first device as the follower uses the transmission path selected by the second device as the master scheduler to send the message, so that the first device and the second device use the same transmission path to send the message Messages, in this way, can be implemented in complex SD-WAN route selection scenarios, and can also ensure the consistency of the path of the message transmitted back and forth between the communication parties while ensuring the quality of service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message transmission method and device. Background technique [0002] Software-Defined Wide Area Network (SD-WAN) is a new technology resulting from the application of Software-Defined Network (SDN) technology in Wide Area Network (WAN). The WAN is mainly used to connect several branches and data centers included in the enterprise network. SD-WAN supports a variety of connection methods, such as multi-protocol label switching (multi-protocol label switching, MPLS) network connection, Internet (Internet) connection, and MPLS and Internet hybrid connection (also known as hybrid-link). In SD-WAN, a client as a communication subject is connected to a site as an access device. The station is used to forward bearer service flow packets for clients connected to the station. In the process of forwarding packets, the site needs to select a transmission path for the ser...
