Embodiment approach 1

[0064] A response rule is configured on the SDN forwarding device, and after receiving the detection message, a response message to the detection message is generated according to the response rule configured on the SDN forwarding device. There are many ways to configure the response rule on the SDN forwarding device. For example, the response rule can be configured through the command provided by the SDN forwarding device. For another example, the response rule can also be configured through the network management system. For another example, it can also Configure the response rule through the SDN controller. These three examples can be used individually or in combination.

[0065] In this preferred implementation, the response rule can take effect after being configured on the SDN forwarding device. At this time, the SDN forwarding device can generate a response message according to the effective response rule after receiving the detection message. The response rule may not...

Embodiment approach 2

[0067] In this preferred implementation, the response rule may not be configured on the SDN forwarding device, and the SDN forwarding device may send the detection message to the SDN controller; the SDN control sends the response rule to the SDN forwarding device after receiving the detection message; The SDN forwarding device receives the response rule sent by the SDN controller; the SDN forwarding device generates the response message according to the response rule.

[0068] Preferably, the response rule is carried in the flow table template sent by the SDN controller to the SDN forwarding device.

[0069]In the above embodiments and preferred implementation manners, the SDN forwarding device may directly send the response message from the port that received the detection message. As a more optimal implementation manner, the SDN forwarding device may also obtain the sending rule from the SDN controller, and then send the response message according to the obtained sending rul...

Embodiment 1

[0113] Configure autonomous response rules on the SDN forwarding device and take effect immediately. Taking ICMP Internet Packet Explorer (Packet Internet Groper, PING for short) detection packets as an example, ICMP Trace Route (Trace Route, Tracert for short) packets are processed in a similar manner. Figure 7 is a schematic topology diagram of the first embodiment according to the embodiment of the present invention, such as Figure 7 As shown, the SDN controller communicates with the forwarding device, and the forwarding device A1 can communicate with the non-SDN device B1 and the management host. Figure 8 is a flow chart of the first embodiment according to the embodiment of the present invention, such as Figure 8 As shown, the process includes the following steps:

[0114] Step S802, log in to the SDN forwarding device through the management host, and configure an autonomous response rule X on the SDN forwarding device A1 through a command line (command-line interfa...

Abstract

The invention discloses a message processing method, an SDN forwarding device and an SDN controller. The message processing method comprises the steps that the software definition network SDN forwarding device receives a detection message; the SDN forwarding device generates a response message of the detection message; the SDN forwarding device sends the response message. By means of the message processing method, the problem that the SDN forwarding device in the related art cannot automatically respond to the detection message is solved, and response to the detection message of the SDN forwarding device is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message processing method, an SDN forwarding device and an SDN controller. Background technique [0002] The TCP / IP-style Internet, because of the division of labor and organization principle of "simple processing by network / network equipment, and complex processing to the host side / side" at the beginning of its design, has formed the current status of the Internet architecture: the host side The application layer protocol can be modified and deployed very conveniently and flexibly, so the application layer software has been developed by leaps and bounds, and the functions of the application layer have been greatly enriched; in sharp contrast to it is the network layer, although the design of the network layer protocol Simple, but the scalability is not strong and it is not easy to modify, resulting in: On the one hand, many fatal loopholes exposed at the Internet network lev...
