Abstract

The invention provides an information synchronization method in a distributed architecture, a forwarding unit and a control unit, which are used for solving the technical problems of link oscillationand the like caused by the fact that the forwarding unit cannot synchronously execute information issued by a main control unit. According to the invention, a synchronization confirmation mechanism isintroduced between the forwarding units, the actual effective time difference of the information issued by the control unit on each forwarding unit is controlled within an acceptable range, link oscillation is avoided, and the service stability is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information synchronization method, a forwarding unit and a control unit in a distributed architecture. Background technique [0002] In the distributed architecture, the main control board completes the service control plane processing, such as route calculation, and sends related entry information to the forwarding line card. Some table entry information is global and needs to be downloaded to multiple forwarding line cards of the device. For example, to issue a route: destination address X mask Y outbound interface Z, the main control board needs to issue such an entry to all forwarding line cards. Another example is to create a bidirectional forwarding detection (BFD) session on the aggregation port. The aggregation port has three member ports, which are located on different forwarding line cards. Send the BFD session information. [0003] The model of the above table i...
