Abstract

The invention provides a flow rule conflict detection method and system based on an alias rule tree. The method comprises the following steps: detecting flow table items to be inserted, wherein the flow table items are corresponding to data flows sent by a data packet; constructing the alias rule tree, and identifying conflicts caused by flow table item insertion according to the alias rule tree; according to the alias rule tree, matching data flow matching information in the flow table items based on a preset logic; analyzing flow rules of the flow table items, and judging whether the flow rules are suitable for combination; if so, analyzing combination conflict and finishing combination of the flow rules; and if not, updating network state read by an application program.

Description

technical field [0001] The invention relates to a flow rule conflict detection method, in particular to a flow rule conflict detection method and system based on an alias protocol tree. Background technique [0002] With the explosive growth of Internet scale and traffic, the traditional network architecture with IP as the core has a bottleneck in the innovative development of new network protocols and the evolution of network technology. Software defined networking (SDN for short) decouples the traditional closed network system into a data plane, a control plane, and an application plane, and realizes logically centralized control and management of the network. The outstanding features of SDN are openness and programmability, which can accelerate the deployment and implementation of network innovation protocols, and have been applied in the fields of network virtualization, data center network, wireless local area network and cloud computing. [0003] The flow rule specifi...
