Abstract
The method for diagnosing network fault nodes (NFN) includes following steps: first, based on testing flow routine utilized by engineers to develop automatic testing software to simulate entire procedure from detecting network paths to searching NFN; then, based on each network device node to use selected protocol (TCP,UDP) to accomplish automatic test; based on network connectivity to accomplish diagnosing fault nodes automatically except only address of target network needs to be filled in for entire testing procedure. The method uses ICMP protocol with quick speed for tracking routes first, and then backs up routes tracked by UDP so as to guarantee probability to find complete route. Moreover, being flexible and effective to detect connectivity of nodes, the method can help to diagnose network fault effectively in practical work.
Description
Technical field
The present invention relates to a kind of network technology, relate to a kind of network fault node diagnosis method specifically.
Background technology
At present, along with complicated network environment, the test of network connectivty and diagnostic work are also numerous and diverse day by day.Network engineers often need to use multiple testing equipment and multiple means of testing that network topology structure is guessed, and in view of the above possible fault point are tested one by one, the difficult point of determining to become the network-in-dialing property testing of fault point.
Network engineers often need be by general ping, instruments such as transrouter determine to arrive the network path of destination address, but because the network equipment is for security consideration, often forbid the agreement that this order relied on---ICMP, caused the engineer can't know complete path node information; Simultaneously, aspect the continuity testing of node, the engineer often needs to adopt UDP, TCP, and various protocols such as HTTP are tested, the final localization of faults position of ability, this often needs the testing tool or the testing software of specialty again.In a word, to the diagnostic procedure of network failure node, lack a kind of effective automatic means of testing.
Summary of the invention
Purpose of the present invention just is according to above-mentioned network failure problem, thus the network fault node diagnosis method that provides a kind of diagnosis of finishing malfunctioning node automatically to test automatically.
Purpose of the present invention can realize by following measure:
The inventive method is as follows:
(1) surveys the purpose network connectivty according to selected agreement
Use transmission control protocol TCP or User Datagram Protoco (UDP) UDP, send transmission control protocol TCP handshaking information or User Datagram Protoco (UDP) UDP message to destination address and destination interface, and wait for that target device replys, by judging return information or overtimely judging whether network can be communicated with;
(2) if network can not be communicated with, at first internet usage control information agreement ICMP carries out route tracking; Find that network can not be communicated with, then the route that arrives destination address is followed the trail of in the route tracking order of internet usage control information agreement ICMP, if all devices is not all forbidden ICMP ICMP on the network, can find complete route;
(3) if internet usage control information agreement ICMP can find complete route, then carry out failure diagnosis
According to the complete routing iinformation that finds, from from the nearest device node of destination address, the connectedness of testing each node to source device node successively.If have a plurality of continuous or discontinuous nodes all can not be communicated with, think that then nearest node has problem; If all nodes can be communicated with, think that then destination device is a malfunctioning node;
(4) if internet usage control information agreement ICMP can not find complete route, then use User Datagram Protoco (UDP) UDP to carry out route tracking:
Internet usage control information agreement ICMP can't find complete routing iinformation, then uses the user datagram udp protocol instead and carries out route tracking operation, can find complete route as this step 1;
(5) find routing iinformation, then carry out failure diagnosis
After using User Datagram Protoco (UDP) UDP to find the routing iinformation of finishing, then can carry out the diagnosis of malfunctioning node, method is the same.
In the method for the present invention: when internet usage control information agreement ICMP searches route, also can find under the situation of complete route, use User Datagram Protoco (UDP) UDP to search route once more, and contrast the result who searches for twice, choose one of them and carry out failure diagnosis.
The present invention is owing to adopt said method, and this method is the detection network malfunctioning node automatically, and in the tracking route operating speed ICMP agreement faster at first, simultaneously the route tracking of UDP is backed up the most, guaranteed to find the probability of finishing route; Simultaneously the method for probe node connectedness is effective flexibly, effective auxiliary network Fault Diagnosis in real work.
