Abstract
The utility model discloses an detection method for detecting the abnormal network nodes. The method arranges the link status zone bit in the communication program; as the communication program starts up, the examination thread is established to examine each link in the link information table, so as to check for the network nodes which are correspondent to the link. If the link status zone bit thereof is under running state and the difference between the present time and the link's message sending time is no less than the pre-set value, the link's correspondent network nodes are judged as abnormal. So, the link shall be closed and informed to the upper level; or, the next link shall be examined. The utility model can conduct the judgment before receiving the other side's heart-beat messages or recv function return or send function return, so as to greatly shorten the testing time used for detecting the abnormal conditions of the network nodes. Also, the call loss is reduced.

Along with the development of intelligent network, more and more higher to the reliability requirement of two net biplane intelligent network communication, when network link broke down, requirement can detect network node abnormality as early as possible, so that take corresponding measure safeguards system reliability.
The unusual method of detection of at present two net biplane intelligent network communication programs has three kinds: 1, communication thread is not received the other side's heartbeat message in the designated time.2, system call recv returns failure.3, system call send returns failure.First method detects needs 25s unusually at least, and during this period of time, upper layer application thinks that link is normal, still sends message, causes producing call loss.Four-way handshake messages when second method and the third method depend on transmission control protocol (TCP) end, when waiting for that close message is responded in the opposite end, this machine TCP is in the TIME_WAIT state, the duration of this state is 2 times the longest merogenesis life cycle (MSL), be generally between 1 fen kind to 4 minute, during this period of time, recv and send can not return failure, thereby can cause producing call loss yet.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of detection method of network node abnormality, shortens detection time, reduces call loss.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of detection method of network node abnormality, this method comprises: every link in setting-up time length scan chain circuit information table, if the transmission thread of detected link is in running status, and the difference that current time and link send the thread transmission message time is not less than preset value, determines the network node abnormality of current detection link correspondence; Otherwise, detect next bar link.
Comprise step before this method: create when communication program starts and detect thread, the link in the link information table is detected by detecting thread.
Comprise step before this method: the Link State flag bit of expression Link State is set, obtains the state of detected link when detecting link by the access link state flag bit in communication program.
Described Link State flag bit represents that link is in running status or blocked state.
When the transmission thread of link began to send message, it was running status that the Link State flag bit is set.
When the transmission thread of link successfully sent message, it was blocked state that the Link State flag bit is set.
Described setting-up time length is 10ms, and described preset value is 100ms.
Comprise step after the network node abnormality of described definite current detection link correspondence: close link, link is set, and whether available flag position IsConnected is unavailable FALSE, and the notice upper layer application.
Described is poll scanning every setting-up time length scan chain circuit information table.
When the current detection link is the last item link detected in the link information table, the epicycle end of scan.
The detection method of network node abnormality provided by the invention, when communication program starts, create one and detect thread, by detecting the mode of thread every link in the link information table is detected with poll, thereby judge whether the pairing network node of detected link is unusual, and need not wait for and receive the other side's heartbeat message, or the recv function returns, or the send function is judged after returning again, whether the network node that can detect every link correspondence in the link information table in 2～10s is unusual, shorten the detection time of network node abnormality greatly, and reduced call loss.

Embodiment
The detection method of network node abnormality of the present invention, when communication program starts, create one and detect thread, by detecting the mode of thread every link in the link information table is detected, thereby judge whether the pairing network node of detected link is unusual with poll.Below be described in further detail by specific embodiment and accompanying drawing detection method network node abnormality of the present invention.
Communication program is created one and is detected thread when starting, and with network on the communication program of other node set up link.Fig. 2 is the system architecture diagram of the two net biplane intelligent networks of the present invention, and as shown in Figure 2, communication program is under the application program, and application has been shielded the communication details.Detect thread and be positioned at communication program, send the state of thread by TCP link information table poll.
Can create the transmission thread when setting up link and be used to send message.The Link State flag bit of expression Link State is set in communication program, when the transmission thread begins to call send transmission message, the Link State flag bit is set is operation (RUN) state, show that sending thread is in running status, and record sends the time of message, successfully send message when sending thread dispatching send, when soon message sends, the Link State flag bit is set for blocking (BLOCK) state.
Detect thread every the mode run-down link information table of 10ms with poll, whether the network node of checking every link correspondence is unusual, Fig. 3 detects the flow chart of the each scan chain circuit information table of thread for the present invention, as shown in Figure 3, detecting the each scan chain circuit information table of thread specifically may further comprise the steps:
Step 31: start detection thread.
Step 32: whether the transmission thread that detects current link is in running status, and whether promptly detect the Link State flag bit is running status.If, execution in step 33; Otherwise promptly the network node of current detection link correspondence does not send message, continue to detect next bar link, returns step 32, when the current detection link is the last item link detected in the link information table, and the epicycle end of scan.
Step 33: judge whether current time and the difference that sends the thread transmission message time are not less than preset value.If the network node abnormality of judgement current detection link correspondence is closed link, link is set, and whether available flag position (IsConnected) is unavailable (FALSE), and the notice upper layer application, so that upper layer application is taked corresponding measure safeguards system reliability; Otherwise, continue to detect next bar link, return step 32, when the current detection link is the last item link detected in the link information table, the epicycle end of scan.For intelligent net system, the time that once sends message is much smaller than 100ms, is 100ms so select preset value at this, if the current time with send difference that thread sends the message time greater than 100ms, then think the network node abnormality of current detection link correspondence.
