Embodiment Construction

[0019] The preferred embodiments are described in detail below in conjunction with the drawings.

[0020] A multi-homing networking method for dispatching stations, such as figure 1 Shown, including:

[0021] Step 1. Combine the access boards of multiple switches into a ring-shaped access network, and the dispatcher will access the network;

[0022] Step 2. Set each dispatching station to use three time slots in the access network. No matter which switch the dispatching station belongs to, the access timeslots used by the dispatching station remain unchanged to ensure that the dispatching station obtains the same dispatching station configuration information;

[0023] Step 3. Each dispatching station belongs to the nearest switch first, and the affiliated switch maintains handshake and state management with the dispatching station;

[0024] Step 4. When the load of the switch to which the dispatching station belongs exceeds the threshold, the dispatching station is dynamically adjusted ...

Abstract

The invention belongs to the technical field of network communication and in particular relates to a multi-homing networking method of dispatch stations, and a network structure; a plurality of switches and a plurality of dispatch stations are included, wherein the switches are connected to one another by means of two interfaces to form a loop network; each dispatch station is connected with the interface of a switch; each dispatch station is set to regularly use three time slots in the accessed network; each dispatch station belongs to the nearest switch preferably; when the load of the attractive switch of the dispatch station exceeds a threshold value or fails, the attribute of the dispatch station is dynamically adjusted to the nearest switch except the switch which has the load of exceeding the threshold value or fails; after the fault recovery of the original attributive switch, the dispatch station belongs to the switch again. The network reliability is strengthened and the networking cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of network communication, and particularly relates to a multi-homing networking method and network structure of a dispatching station. Background technique [0002] In the dispatching system, the dispatching console and the switch generally adopt a point-to-point connection. If the communication security of the system is considered, each dispatching station has at most two interfaces connected to a switch respectively to realize 1+1 backup of physical connection. The advantage of this networking is that one physical channel of the dispatching station is interrupted and another channel can be provided. The disadvantage is that after both channels are interrupted, the dispatching station cannot communicate. Summary of the invention [0003] In view of the above problems, the present invention proposes a multi-homing networking method for dispatching stations, including: [0004] Step 1. Combine the access boards of...
