Abstract
The invention provides a method for automatically having access to the network. The method includes the steps that a server terminal starts a UDP to conduct broadcasting and sends a UDP information packet; a client terminal receives the UDP information packet and obtains the IP address of a server from the UDP information packet; according to the IP address of the server, TCP network connecting is built. By means of the method for automatically having access to the network, positive registering, reconnection after offline and intelligent heartbeats are achieved.
Description
Technical field
The present invention relates to internetwork connection mode, refer to especially a kind of method of automatic interconnection network.
Background technology
At present computer is connected when IP address is set generally employing automatic acquisition IP technology or two kinds of assigned ip addresses mode is set with the Internet.Generally client can select automatic acquisition IP address, after an equipment access local area network (LAN) is complete, no matter be that service end or client all must be by inquiries, determine IP each other, and connect IP by arranging, realize a service end and connect multiple clients, these generally will arrange one by one in client.So inefficiency, arranges trouble.
Ethernet communication mode mainly contains two kinds of TCP and UDP mode, and what nowadays the Internet was mainly applied is TCP technology, once its advantage is to establish to connect just very stablely, must manually arrange but connect IP.The Principle of Communication of UDP based on one-to-many, it sends an instruction to multiple intrasystem all devices, but not all equipment can receive instruction exactly, and equipment successful receiving rate can not reach very, cause some equipment to fail to be connected with the normal data of system made
Summary of the invention
The present invention proposes a kind of initiatively registration, disconnection reconnecting, the method for the automatic interconnection network of intelligent heartbeat.
Technical scheme of the present invention is achieved in that
A method for automatic interconnection network, comprising:
Server end starts UDP broadcasts, and sends UDP packets of information;
Client UDP packets of information, the IP address that therefrom obtains server;
According to the IP address of server, set up TCP network and connect.
The present invention initiatively sends broadcast frame address by server end, client is registered connection to rear active, because udp protocol can be one-to-many communication, therefore can realize the rapidity that information sends, after connecting, use the network of TCP more stable.Connected mode of the present invention is more initiatively with convenient.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the flow chart of the method for a kind of automatic interconnection network of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
A method for automatic interconnection network, comprising:
Server end starts UDP broadcasts, and sends UDP packets of information; (step 1)
Client UDP packets of information, the IP address that therefrom obtains server; (step 2)
According to the IP address of server, set up TCP network and connect.(step 3)
Preferably, starting UDP at execution server end broadcasts, the step that sends UDP packets of information also comprises step before: in client access network, also completing circuit loads, local IP obtains, be that udhcpc is until server is received data, and sending response in UDP mode, server end starts UDP broadcasts, and sends UDP packets of information; The response that client is sent to server end, completes log-on message configuration automatically according to the IP address of its appointment, has registered rear equipment and is available this specific assigned address and set up stable data with server in the mode of TCP and be connected.
Preferably, carry out according to the IP address of server, set up TCP network connect step after, also comprise server according to predetermined time interval send heartbeat to client, client is made corresponding response; In the time that the time that client is responded exceedes Preset Time, server end is closed TCP thread or is destroyed TCP thread.Due to
Between server and client between communication period, client may be extracted suddenly or be accessed in hot-swappable mode, also may be due to equipment or network failure and cannot with system communication, cause interruption, server can not be reacted and the transmission information that does as usual within the utmost point short time under normal circumstances, data cannot incoming terminal equipment in this case, and server can not be taked countermeasure to equipment immediately.Tradition communication mechanism is almost manually to intervene in broken string situation, re-creates connection, if could not find in time and reconnect server and client will cannot normally be worked in off-state.In order to tackle above-mentioned situation, disconnection reconnecting and intelligent heartbeat mechanism are adopted set up stable connection between server end and client after.After system has been dynamically connected certainly, just produce heartbeat, be to send a heartbeat packet to target several seconds, if equipment nonreply in 2 seconds, expression is connected with server and client are unsuccessful, now server and client all can automatically disconnect between existing connection, client sends log-on message in UDP mode again, sets up TCP mode 1 be connected 1 by auto registration process and server.Once connect, it is normal that heartbeat just recovers, as long as client is received heartbeat always, will each heartbeat be produced and be replied, server receives replys, and server is just in stable connection status, and attendant can understand from the existence of heartbeat the real-time status of client.
Preferably, predetermined time is spaced apart 3-5s.
Preferably, Preset Time is 2s.
The method of automatic interconnection network provided by the invention, can auto registration, disconnection reconnecting, intelligent heartbeat mechanism, allows the whole-process automatic registration of system, connection, detection, without manual intervention, has fully improved stability and the operation ease of system.After equipment inserts, connection procedure is full-automatic, and moment detection mixes use, heartbeat packet with protection, Auto-reconnect, TCP with UDP; Make speed faster, system is more stable.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (5)
1. a method for automatic interconnection network, is characterized in that, comprising:
