Problems solved by technology
However, the listening port number of the current reverse Telnet is determined by the software of the router, so when the software version of the router is determined, the listening port number of the reverse Telnet cannot be modified, so the current reverse Telnet cannot meet the requirements Requirements for planning to assign device port numbers
[0008] 2. The current reverse Telnet cannot flexibly realize the backup of terminal device control
In this way, when the connection of the management channel is abnormal, the terminal device cannot be managed through the port number on the Telnet client
[0009] At present, although a terminal device can be accessed through different reverse Telnet port numbers, a terminal device needs to correspond to multiple different port numbers in use, which not only wastes a lot of port number resources, but also makes it difficult to use and maintain bring a lot of inconvenience

Embodiment Construction
[0033] First of all, it needs to be explained that in the present invention, for each synchronous and asynchronous serial port, the monitoring port number and the monitoring socket (socket) number of the serial port will be recorded. When the router starts, use Telnet technology to carry out conventional initialization of the monitoring port number of each synchronous and asynchronous serial port, and establish corresponding monitoring sockets according to the monitoring port number.
[0034] The listening port number refers to the reverse Telnet listening port number int_listen_port of the synchronous and asynchronous serial port, which indicates the current listening port number of a synchronous and asynchronous serial port. to modify. This is one of the characteristics of the present invention.
[0035]The monitoring socket number refers to the socket number int_socket_id of the reverse Telnet monitoring process of the synchronous and asynchronous serial port, which record...

The invention provides a method of building reverse Telnet-based terminal management channel backup in router, and its characteristic: it includes: as the reverse Telnet client end requests to build management channel to terminal equipment, in the router, configuring the corresponding relation between reverse Telnet monitoring port number of the terminal equipment and asynchronous-synchronous serial port of the router; and according to the above serial port, building management channel between the reverse Telnet client end and the terminal equipment. The method can realize united planning for port numbers of terminal equipment needed to be managed, and set port number according to concrete need, and can realize supporting other softwares. In addition, it can realize backup function for terminal equipment management by building many management channels to the terminal equipment by fixed port number.
Description
field of invention [0001] The invention relates to the management of the communication network, in particular to a method for backing up the management channel of the network by using reverse Telnet (remote login). Background technique [0002] Now many terminal devices need to be managed in a central network. In order to save engineering costs and improve the speed of data collection, it is necessary to use the existing network resources and bandwidth as much as possible. [0003] In this regard, use the reverse Telnet method to connect the synchronous and asynchronous serial port of the router to the terminal device, and connect the management center device to the router through the WAN, so that the management center device can pass "Telnet router address + synchronous and asynchronous serial port number "The way to establish a connection with the terminal equipment to realize the management of the terminal equipment (for example, in the network management center, the alar...
