[0003] The OpenFlow protocol stipulates that flow table matching is a serial rule, that is, matching is performed according to the priority of the OpenFlow flow table. After the packet is matched to the corresponding OpenFlow flow table, the corresponding action in the OpenFlow flow table is executed on the packet. However, the matching of packets in the current OpenFlow switch adopts the principle of parallel matching, that is, it is possible for a packet to match multiple OpenFlow flow tables, but since the OpenFlow flow table includes the OpenFlow service flow entry and the OpenFlow default flow table item, the matching field in the OpenFlow default flow entry is any, and the action is drop. Therefore, any packet can match the OpenFlow default flow entry, and the packet can match the OpenFlow default flow entry and the OpenFlow service at the same time. When flow entry, because the priority of the drop action is higher than that of other actions, the packet will be discarded, which may cause all the packets to be discarded, that is, the original expected to be forwarded to a certain egress. The message is also discarded, resulting in incorrect processing of the message and affecting the correct transmission of the message

The embodiment of the present application provides a message processing method, device and electronic equipment, the method including: receiving the OpenFlow message to be processed; judging whether there is an OpenFlow service flow table matching the OpenFlow message to be processed in the OpenFlow flow table Item and the OpenFlow default flow entry, when there is an OpenFlow service flow entry and an OpenFlow default flow entry matching the OpenFlow message to be processed, the OpenFlow message to be processed executes the business action in the OpenFlow service flow entry. In this solution, the service execution action in the OpenFlow service flow entry is executed for the OpenFlow message to be processed, thereby ensuring that the OpenFlow message can be processed correctly, and avoiding the problem of error handling in which all OpenFlow messages are discarded in the prior art .
Description
technical field [0001] The present application relates to the technical field of communications, and in particular, to a message processing method, device, and electronic equipment. Background technique [0002] The SDN (Software Defined Network, Software Defined Network) architecture has the characteristics of separation of control plane and forwarding plane, open programmable interface, centralized network control and automatic application control of network services, and is more and more respected by the industry. Among them, OpenFlow is a kind of standardized southbound interface in the SDN network architecture. In the OpenFlow protocol, the SDN controller communicates with the communication device (such as a switch) through a standard message interface. The protocol defines that the OpenFlow flow entry includes a matching field (there can be multiple matching fields) and an action (action) field. SDN The controller sends the OpenFlow flow table to the switch through th...
