Embodiment Construction

[0067] The application will be described in further detail below in conjunction with the accompanying drawings.

[0068] The embodiments of the present application provide a message forwarding method and device, which are used to solve the problem in the prior art that the TTL value of each IP message is processed many times in an SDN network, resulting in a large consumption of system resources. Wherein, the method and the device described in this application are based on the same inventive concept, and since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0069] In the technical solution of the embodiment of the present application, the controller determines the forwarding path between the source device and the destination device, the forwarding path includes N forwarding devices, and N is a positive integer greater than or equal to 2; ...

Abstract

The invention relates to a message forwarding method and a device, which are used for solving the problem that the TTL value of an IP message is processed more times in an SDN network in the prior art, and more system resources are consumed. The controller determines that the forwarding path between the source device and the destination device includes N forwarding devices, determines that the number of times to be forwarded of the IP message to be forwarded sent from the source device to the destination device is N, and determines a first forwarding strategy of the first forwarding device according to the number of times N to be forwarded, so that the first forwarding device performs N reduction processing on the TTL value in the IP message corresponding to the IP address of the destination device, and then forwards the processed IP message. And the controller determines a second forwarding policy of at least one second forwarding device to cause each second forwarding device to forward an IP message corresponding to an IP address of the destination device. In this way, the processing times of the TTL value can be reduced, and the consumption of system resources can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device. Background technique [0002] Software-defined networking (SDN) is a communication network that separates the control layer from the forwarding layer. The SDN network includes an SDN controller and multiple forwarding devices. The SDN controller is used to control and manage the multiple forwarding devices, and generate each forwarding device according to the Internet Protocol (Internet Protocol, IP) addresses of the hosts connected to the multiple forwarding devices and the topology of the multiple forwarding devices. The forwarding policy of the device is used to instruct the forwarding device to forward the IP packet including the destination IP address corresponding to the forwarding policy. Each forwarding device is configured to determine a corresponding forwarding policy according to the destination IP address ...
