Abstract

The invention provides a data processing method and device, a medium and a computer program product, and the method comprises the steps: a first controller receives role response information sent by a first switch, and updates a locally stored first database according to the role response information. The first controller adds first summary information including a first survival time of a first database to a first content summary information list, and broadcasts the first summary information to other controllers. And a second controller of which the time for receiving the first summary information is earlier than the first survival time in other controllers sends a first database updating request to the first controller, and the first controller sends updating data of the first database to the second controller, so that the second controller updates a locally stored second database. According to the method, the summary information containing the survival time is created, the situation that all the controllers receive the summary information is avoided, the database synchronization pressure is dispersed to all the controllers, and the database synchronization pressure of the first controller is reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a data processing method, device, medium and computer program product. Background technique [0002] In a software-defined network (Software Defined Network, referred to as SDN), its core technology Openflow (Openflow) separates data from control. In the control layer, including logic centralization and programmable controller, it can grasp the global network information, which is convenient for users to manage and configure the network and deploy new protocols. At the data layer, including switches that forward data, matching packets can be processed quickly. The controller issues unified standard rules to the switch through the standard interface, and the switch performs corresponding actions according to the rules. [0003] In order to increase the penetration rate of SDN networks, it is necessary to ensure the data consistency of SDN controllers....
