Abstract

The present application provides a method and device for updating data. The method is applied to forwarding equipment, including: receiving configuration data sent by the server; sending mode based on the configuration data, and configuration data and current version stored in the cache information, to update the configuration data in the forwarding device; wherein, the cache is used to store the configuration data and the current version information of the stored configuration data. Through the technical solution of this application, the problems in the prior art are solved, and the idempotency and correctness of the configuration data in the incremental delivery mode can be ensured, and the stability and consistency of the configuration data in the full delivery mode can be guaranteed, ensuring that no Packet loss, continuous flow.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method and device for updating data. Background technique [0002] In the prior art, a forwarding device in a data network carries user traffic at any time. If a forwarding entry of the forwarding device is lost at a certain moment, user data flow will be cut off. However, in the virtual network, the demand for user-defined networks is large, which leads to the management and control system frequently issuing various entries, resulting in a high probability of entry loss, which in turn leads to traffic interruption. In this case, the configuration data is usually delivered in incremental delivery mode, and more frequent delivery may cause some other abnormalities. For example, the entry in the configuration data delivered by the management and control In this case, the incremental delivery mode cannot solve the above problems. If the full delivery mode i...
