Abstract
The invention discloses a method and system for detecting line quality problems of a broadband access network. The detection method includes the following steps that on-line data packs of broadband users are captured on links of a kernel layer or a convergence layer of an IP metropolitan area network through collection equipment; TCP data streams of each broadband user are tracked, the TCP pack total number A and the TCP repeated pack number B of each user are calculated, the TCP repeated pack rate Nr which is equal to the result that A is divided by B is calculated, and then the corresponding relationship between IP addresses of the broadband users and the Nr is recorded; the TCP repeated pack rate Nr of each broadband user is checked, if Nr is larger than Tr, the IP address of the corresponding user is recorded in an abnormal line user database, and otherwise, the IP address of the corresponding user is recorded in a normal line user database; Tr is a set threshold of the TCP repeated pack rate; the IP addresses of all users of the abnormal line user database are output. According to the method and system, the TCP repeated pack rate of each broadband user is calculated, and accordingly the broadband user whose broadband access line has quality problems is found.
Description
Technical field
The invention belongs to network communications technology field, relate to a kind of line quality detection method, relate in particular to a kind of detection method of broadband access network line quality problem; Meanwhile, the present invention also discloses a kind of detection system of broadband access network line quality problem.
Background technology
In recent years, along with the fast development of the Internet and application thereof, broadband user's quantity is rapid growth trend, and various Broadband Access Network Technologies (as xDSL, FTTx, LAN, Cable Modem, EoC) also emerge in an endless stream.Because broadband user's number of, lines is huge, and various broadband access technology characteristics are different, the network operation work of Zhe Gei telecom operators proposes very large challenge, and telecom operators often need to spend the various complaints that a large amount of manpower and materials are processed broadband user.
On the other hand, along with the propelling of the integration of three networks, telecommunications and radio and TV operator are also increasingly sharpened in the competition of broadband access market.In order to enhance the competitiveness, operator not only needs fast processing broadband user's various complaints, the more important thing is the subscriber's line that can initiatively find to exist potential quality problems, and timely troubleshooting, by preventive maintenance mode, reduces customer complaint rate.
Traditional broadband access network maintenance mode is generally: engineering maintenance personnel portable hand-held test instrumentation (as adsl line instrument, light power meter etc.) carries out Circuit Quality Test and malfunction elimination to user scene.This maintaining method is more effective for broadband services commissioning and specific user's fault complaint handling, but be not suitable for all subscriber's lines to carry out Daily Round Check test, its main cause is that number of broadband customers is huge, this maintenance mode must send attendant to test to scene, and operator often cannot bear so huge personnel and drop into.Therefore, operator needs urgently to find and a kind ofly without a large amount of human inputs, but can initiatively filter out the method for the subscriber's line that has potential quality problems, then send targetedly attendant to user scene, use test instrument is carried out malfunction elimination test to these subscriber's lines.
Broadband user mainly uses the online application based on Web at present, and this Web application all adopts HTTP/TCP protocol stack.Because Transmission Control Protocol has error recovery mechanisms, when broadband access network circuit exists quality problems and produces packet loss, terminal equipment will ask Web server to retransmit lost packet.
Fig. 1 be one because broadband access network line impairment causes Network Packet Loss, and by TCP retransmission mechanism, carried out the example of loss recovery.From this example, we can see in IP kernel heart net side and not occur any IP packet loss, but because Access Network circuit question causes 2 IP packet losses, thereby cause that TCP retransmits, and therefore can detect 2 TCP duplicate packages at core net test point.In certain hour section, if there is the TCP bag of two or more same sequence number and content in same TCP stream, the TCP bag occurring below can be TCP duplicate packages by statistics.
In view of this, nowadays in the urgent need to designing a kind of method that detects broadband access network line quality problem, to overcome the above-mentioned defect of existing system.
