no. 1 example

[0036] see figure 1 , the embodiment of the present application provides a message forwarding system 10 , the message forwarding system 10 includes: a communication network 11 , a first IP network segment 12 , a second IP network segment 13 and a controller 14 .

[0037] The communication network 11 is used to connect the first IP network segment 12 and the second IP network segment 13, so as to realize the cross-network segment forwarding of messages, that is, the first IP network segment 12 sends data to the second IP network segment through the communication network 11 13, where the first IP network segment 12 can be a wide area network, and the second IP network segment 13 can be a service network. In order to realize the forwarding effect, at least one tunnel is set up in the communication network 11, and each tunnel can connect the first IP network segment 12 and the second IP network segment 13 respectively, and each tunnel can be an L2TP tunnel (Layer 2 Tunneling Proto...

[0042] see figure 1 , the embodiment of the present application provides a message forwarding method, the message forwarding method is applied to a node device in a communication network, and the message forwarding method includes: step S100, step S200 and step S300.

[0043] Step S100: Obtain the tunnel message to be forwarded.

[0044] Step S200: According to the outer layer destination IP address of the tunnel message to be forwarded, it is determined that the tunnel message to be forwarded needs to be decapsulated.

[0045] Step S300: Obtain the inner layer destination IP address in the tunnel message to be forwarded for routing and forwarding.

[0046] The flow of the message forwarding method will be described in detail below.

[0047] Step S100: Obtain the tunnel message to be forwarded.

[0048] The node device in the communication network can obtain the message to be forwarded through its own WAN interface, but when obtaining the message to be forwarded, the node d...

[0070] see image 3 , the embodiment of the present application provides a message forwarding device 100, the message forwarding device 100 is applied to each node device in the communication network, the message forwarding device 100 includes:

[0071] The packet obtaining module 110 is configured to obtain tunnel packets to be forwarded.

[0072] The decapsulation module 120 is configured to determine that the tunnel message to be forwarded needs to be decapsulated according to the outer destination IP address of the tunnel message to be forwarded.

[0073] The first forwarding module 130 is configured to obtain the inner layer destination IP address in the tunnel message to be forwarded for routing and forwarding.

[0074] The second forwarding module 140 is configured to perform routing and forwarding according to the outer destination IP address of the tunnel message to be forwarded when it is determined that the tunnel message to be forwarded does not need to be decapsu...

Abstract

Embodiments of the present application provide a packet forwarding method, device, and storage medium, and relate to the technical field of communications. The method includes: obtaining the tunnel message to be forwarded; determining that the tunnel message to be forwarded needs to be decapsulated according to the outer destination IP address of the tunnel message to be forwarded; obtaining the inner destination IP address in the tunnel message to be forwarded for routing and forwarding . It realizes that the tunnel packet to be forwarded can be directly forwarded to its destination device without the participation of other node devices in forwarding the node device, thereby avoiding the repeated forwarding of other node devices becoming a network performance bottleneck, and making full use of the available links to carry out Forwarding improves link utilization.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a forwarding path detection method, device, and storage medium. Background technique [0002] After the device is deployed in the WAN, in order to ensure the reliability of the device processing services, multiple WAN lines are often used to perform link backup and traffic sharing for the services on the device. But at the same time, it also brings corresponding problems. For example, setting up multiple WAN lines, especially dedicated line lines, brings high costs and low utilization. [0003] In order to solve the high cost of multiple WAN lines and the low utilization rate, the industry has unanimously promoted the use of SD-WAN technology (Software-Defined Wide Area Networking, Software-Defined Wide Area Network) in recent years. SD-WAN is the concept of separation of control and forwarding with the help of SDN (Software Defined Network, software-defin...
