Problems solved by technology

[0041] Possible problems: Since this method requires the active and standby to start in the same initial state and receive the same input, it is only suitable for the active and standby to start at the same time, and code updates, online upgrades, and card updates are not allowed in the middle hot swap
[0055] This protocol extension method must be used on the data network device and its peer nodes at the same time. If the peer node does not support Graceful, it cannot be used
Therefore, it is impossible to achieve high availability in various complex network environments only by using protocol extension.

Abstract

The invention uses the combination of the software and the hardware to improve the speed and accuracy of the fault detection; in the approach for main equipment protection or recovery, it uses a self-adaptive main equipment protection and recovery approach. Wherein, when equipment runs at a non-route signaling mode, it uses a partly synchronous method, and when it runs at a route signaling mode, it firstly decides if all neighboring nodes have the protocol expanding functionality; if yes, using the protocol expanding approach to make main equipment protection; otherwise, using the state fully synchronizing approach.

Description

technical field [0001] The present invention relates to data network equipment, in particular to a management control method and control device for realizing high availability (HA, High Availability) on data network equipment, and the data network equipment with such a control device. Background technique [0002] High availability in practice [0003] With the rapid development of the Internet (Internet), the network has poured into every corner of social life, people's life is increasingly inseparable from the network, and there are more and more key applications of the Internet. Therefore, the stability of the network And reliability requirements are getting higher and higher. Every minute of downtime (down) of data network equipment will bring great losses to operators and enterprises. According to a report by Sterling Research, a one-hour down opportunity cost a New York City stock exchange $6.5 million, and an ATM lost $15,000. Therefore, high availability has becom...
