System and method for achieving management of serial server

Abstract

The invention provides a system and a method for achieving management of a serial server. The system comprises a first subnet, a second subnet, a serial server and a first monitoring server, wherein the serial server and the first monitoring server are arranged under the first subnet. After the serial server jumps to the second subnet from the first subnet, the serial server appoints the first monitoring server in the first subnet to be an attribution server. After the serial server jumps from the first subnet to the second subnet, the first monitoring server manages the serial server according to an appointed webmaster of the serial server. The system can still enable the monitoring server to effectively manage the serial server when relative positions of the serial server and the monitoring sever change and can still keep high disaster tolerance when any party of the serial server and the monitoring server is delayed, thereby improving reliability and safety of the network.

Description

technical field [0001] The invention relates to a technology for realizing management of network equipment in the field of serial port communication, in particular to a system and method for realizing management of a serial port server. Background technique [0002] The serial port server is connected to the network to realize serial port services, such as virtual serial port services. Therefore, it is usually necessary to manage the serial server through the monitoring server. At present, the most common management strategy is to discover the ownership management strategy, that is, the monitoring server is the active party to send a broadcast message in a specific format to the broadcast address in the subnet, and the serial port server that receives the broadcast message sends back the registration authentication to the monitoring server. message, so as to realize the management of the serial port server by the monitoring server, and the serial port server performs serial...

AI Technical Summary

Problems solved by technology

[0004] (1) If the serial port server has a subnet location transition, then the serial port server will be taken over by other monitoring servers of another subnet; in this case, if the user needs the serial port server to still provide the serial port business, it will not be possible due to changes in the monitoring server that manages the serial port server

[0005] (2) If the monitoring server in the subnet is down (such as downtime, or shutdown, or disconnected from the network due to other reasons), and the serial port server managed by the monitoring server does not have other monitoring servers in the subnet to found, the serial port server will be in a free state, and the services it provides will be paralyzed, causing irreparable losses, that is, the network has poor disaster tolerance.

[0006] It can be seen that in the existing network system for managing serial servers, a single discovery and ownership management will make it impossible to continue to provide the original serial services to users after the subnet location transition of the serial server occurs, or when the When it goes down, the disaster tolerance of the network is reduced
