Problems solved by technology

[0006] For example, in some large data packet transmission scenarios, such as user packet burst transmission, or a large number of users switch to a new forwarder at the same time, the forwarder may receive a large number of user packets belonging to the same flow at the same time , resulting in a large number of concurrent message reporting messages
These message reporting messages not only consume the computing resources of forwarders and controllers, but also occupy signaling transmission resources, such as causing the failure of flow rule installation message transmission, which in turn will lead to more message reporting messages, making the control of the entire system Interface is overloaded

[0067] figure 2 A schematic diagram showing a sequence of a packet processing method in a control-forwarding decoupling architecture according to an embodiment of the present invention.

[0068] This embodiment takes the OpenFlow protocol as an example. The OF forwarder obtains the message reporting control information by receiving the configuration message from the OF controller, and caches the unreported message belonging to the same flow to the same flow as the reported message of the flow. cache with the same ID in the cache. Wherein, the unreported message refers to the message for which the corresponding message report message has not been sent, and the reported message refers to the message for which the corresponding message report message has been sent. Such as figure 2 As shown, the basic flow of the message processing method includes:

[0069] 1. When the OF forwarder establishes a connection with the OF controller, the OF controller sends the message reporting...

[0082] This embodiment takes the OpenFlow protocol as an example. The OF transponder obtains the message reporting control information by reading the local configuration information, and caches the unreported messages belonging to the same flow to the cache area associated with the reported messages of the flow. in the cache area. Such as image 3 As shown, the basic flow of the message processing method includes:

[0083] 1. Before the OF forwarder executes the reporting of the message to the OF controller, it obtains the message reporting control information from the local configuration information.

[0084] Wherein, the message reporting control information may include information such as a reporting control indication and a control threshold. In a possible implementation manner, ...

[0093] Figure 4 A schematic diagram showing a sequence of a packet processing method in a control-forwarding decoupling architecture according to another embodiment of the present invention.

[0094] In this embodiment, the OpenFlow protocol is taken as an example. The OF transponder obtains the message reporting control information by reading the local configuration information and receiving the configuration message from the OF controller, and buffers unreported messages belonging to the same flow to the same flow. The cache area of ​​the reported message has the same ID in the buffer area. Such as Figure 4 As shown, the basic flow of the message processing method includes:

[0095] 1. The OF transponder acquires the first packet reporting control information from local configuration information when it is started.

[0096] Wherein, the control information reported by the first packet may include information such as a report control indication, a first control threshold...

Abstract

The embodiment of the present invention discloses a message processing method, a forwarder, a message processing device, and a message processing system applicable to a control and forwarding decoupling architecture including a forwarder and a controller, including: the forwarder acquires control instructions including reporting and The packet reporting control information of the control threshold; and the forwarder stops sending the packet reporting message related to a flow when the control parameter reaches or exceeds the control threshold according to the reporting control instruction. By controlling the sending of message reporting messages belonging to the same flow according to the message reporting control information, unnecessary message reporting can be effectively reduced, thereby effectively improving the efficiency of flow rule requests, reducing the load on the control forwarding interface, and reducing the control resource occupation of switches and transponders, and improve the stability of system operation.

Description

technical field [0001] The invention relates to network communication, in particular to a message processing method, a transponder, a message processing device, and a message processing system under a control-forwarding decoupling architecture. Background technique [0002] In the current telecommunication network, there are many complex network devices, such as routers, gateways, switches, firewalls and various servers. These devices support various network protocols respectively, so as to realize the interconnection and intercommunication between network elements. Each device is composed of an internal message forwarding module and various protocol control modules. This distributed control module deployment method makes the deployment and management of the network very complicated. In order to modify or upgrade a certain control parameter, the network operator must perform separate operations on each device. [0003] In order to solve the deployment flexibility and manag...
