Abstract

The embodiment of the invention discloses an elegant restart method, equipment and system, relates to the field of data communication, and realizes uninterrupted forwarding of service flow. The methodcomprises the following steps: after an MLAG process of home terminal network equipment is restarted, loading MLAG configuration, and recording an initial port state of an LAG port of the home terminal network equipment into a temporary table; sending a negotiation message to opposite-end network equipment in the MLAG domain so as to reestablish a pairing relationship with the opposite-end network equipment; enabling the home terminal network equipment to start a timer, interact a synchronization message with the opposite terminal network equipment, calculate the current port state of the LAGport, and update the current port state to the temporary table; and if the timer is overtime, enabling the home terminal network equipment to compare the table item corresponding to the LAG port in the temporary table with the table item corresponding to the LAG port in the external setting database of the home terminal network equipment so as to determine whether to update the hardware forwarding plane of the home terminal network equipment and the external setting database.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a method, device and system for graceful restart. Background technique [0002] Multi-Chassis Link Aggregation Group (MLAG) technology is a cross-device link aggregation technology that virtualizes two physical devices into one device at the aggregation level to achieve cross-device link aggregation. This provides device-level redundant protection and traffic load. In the network topology of MLAG technology, one MLAG domain contains two paired network devices. In this network topology, if the MLAG process on any of the two paired network devices in the MLAG domain restarts, how to implement MLAG During process restart, the uninterrupted forwarding of service traffic passing through the network device is an urgent problem to be solved. Contents of the invention [0003] The present invention provides an elegant restart method, equipment and system, which are used ...
