Abstract
The invention discloses a system and a method for controlling uninterrupted routing during switching of a main disk and a spare disk of a plane, which relate to the technical field of communication, and the method comprises the following steps: when the master disk operates the socket, the related information of the socket is stored in a first socket agent module, and then the stored socket information is synchronized to a second socket agent module; after receiving the socket information, the second socket agent module stores the socket information and calls a TCP/IP module interface of the standby disk to acquire a corresponding socket; when the main disk and the standby disk are switched, the second socket agent module traverses the socket information stored locally and replaces the standby disk protocol module to provide the keep-alive messages of the protocols corresponding to the sockets; after the switching between the main disk and the standby disk is completed, the socket proxy module stops replacing the standby disk protocol module to provide the keep-alive messages.

Description
Technical Field
The invention relates to the technical field of communication, in particular to a system and a method for controlling uninterrupted routing during switching of a main control plane and a spare control plane.
Background
For telecommunication level routers, the Non-Stop Routing (NSR) is one of the core technologies for achieving more than 5 and 9 reliabilities, and the NSR is a threshold-level requirement related to the reliability of a high-end router. Compared with a Non-Stop Forwarding (NSF) technology without high availability or standardization, the NSR can limit network faults inside nodes, and ensures that a data plane does not have flow interruption under the condition that a control plane fails, so that the reliability is higher; compared with the NSF technology, the method has lower requirements on deployment environment and does not need the cooperation of neighbor nodes.
Generally, in order to implement uninterrupted routing, after a failure or failure occurs in a primary disk of a control plane, the primary disk needs to be switched to a standby disk immediately, that is, the standby disk is promoted to be a logical primary disk, and after the promotion process is started, a relevant protocol module supporting the NSR technology needs to send a protocol keep-alive message immediately to ensure that a protocol is not disconnected with a neighboring device node. Depending on the control plane protocol stack used, the time required for the ramp-up from the standby disk to the successful sending of the keep-alive messages may be on the order of seconds or even minutes.
Particularly, in a routing device in an application scenario where a spare disk program is in an inactive or partially active state, that is, a spare disk module only has a data synchronization function with a main disk module, and when a state machine of a protocol module is not normally migrated, time consumed in the upgrade process may reach ten minutes or more, and the spare disk protocol module does not have message creation and outgoing capabilities within this time period, and cannot send a keep-alive message. Because the keep-alive time of the keep-alive message in the common protocol module is generally within 1 minute, and when the keep-alive time is exceeded, the protocol state between the data plane and the neighbor device node is changed into DOWN, so that the data plane route is withdrawn, and the serious consequence of flow interruption is caused.
