In wide band access user, PPP (Point-to-point Prototal, peer-peer protocol) and portal protocol be two kinds of main access waies, ppp protocol specifically is divided into PPPOE (PPP over Ethernet) and two kinds of access waies of PPPOA (PPP over ATM).

PPP is a kind of agreement of point-to-point, has obtained immense success in narrowband dialing is used.As the extension that narrowband dialing is used, the PPPoE agreement has realized the carrying of ppp protocol on Ethernet, realizes that the point-to-point on the Ethernet connects; Equally, the PPPOA agreement has realized the carrying of ppp protocol on ATM.The user can pass through the ppp protocol accessing to wide band network at present.

When the method for assessment broad band network quality of the present invention is used to assess broadband network PPP access customer call quality, because the PPP access way is divided into two kinds of PPPOE and PPPOA, and user's access procedure difference under the dual mode, therefore need set in advance network index, gather the network index information of corresponding network layer according to described network index automatically; Then described network index information is converted into corresponding network index according to pre-defined rule; Insert user's call quality then according to described network index assessment.

PPPOE is the connection of the point-to-point set up on Ethernet, and PPPOE finishes this function by the Discovery agreement, and the Discovery link setup stage comprises 4 steps:

PADI (The PPPOE Active Discovery Initiation): initialization procedure, send broadcasting by client, purpose is to find to provide the far-end server (being AC) of service.

PADO (The PPPOE Active Discovery Offer): the service response process is provided, and server receives PADI bag back and sends out service response PADO to client, and purpose is to tell client to provide service for it.

PADR (The PPPOE Active Discovery Request): service request procedure, client proposes service request to the server of selecting, and purpose is Session id of requirement server-assignment.

PADS (The PPPOE Active Discovery Session-Confirmation): the session setting up procedure, Session id of server-assignment gives client.

After sending the PADS message on the BAS, show the success of PPPOE negotiation phase, begun to enter the ppp negotiation stage.

The ppp negotiation stage mainly contains three parts and forms: LCP (Link Control Protocol, LCP layer negotiation phase, authentication phase and NCP (Network Control Protocols, network layer protocol layer) negotiation phase.Wherein, LCP is mainly used in foundation, removes and monitoring PPP information link.Network layer protocol is mainly used in the form and the type of negotiation institute's data packets for transmission on this data link.Authentication phase is provided for the indentification protocol of network security aspect, mainly is PAP agreement (PasswordAuthentication Protocol, password authentication protocol) and CHAP agreement (Challenge-HandshakeAuthentication Protocol).

Fig. 2 shows PPPOE mode access procedure, and the network index information that need gather when inserting in this kind mode, described network index information comprises PPP user's surf the Net network index information in stage of the network index information of negotiations process and PPP user of surfing the Net, the surf the Net network index information of negotiation phase of described PPP user specifically comprises: PPP user's number of times that makes a call, PPP user is connected to the BAS Broadband Access Server number of times, PPP authentification of user number of success, PPP user's number of success of surfing the Net, PPPOE consults the frequency of failure, LCP consults the frequency of failure, PPP user authentication failure number of times, PPP user's charging failure number of times, the surf the Net network index information in stage of PPP user comprises the abnormal off-line number of times, PPP user's number of times that normally rolls off the production line.Surf the Net the stage with surf the Net negotiation phase and PPP user of dotted line difference PPP user among the figure.The PPP customer call stage frequency of failure is PPP user's normal call frequency of failure and PPP user's abnormal call frequency of failure sum.

Wherein, PPP user makes a call and receives PADI message number of times on number of times=BAS;

PPP user is connected to the last PPPOE of BAS Broadband Access Server number of times=BAS and consults number of success;

The last chap authentication number of success of the last pap authentication number of success+BAS of PPP authentification of user number of success=BAS;

The PPP user's last PPP user of number of success=BAS number of success of chargeing of surfing the Net;

The PPP user offline number of times of PPP user's abnormal off-line number of times=initiate by BAS;

Normally roll off the production line number of times=of PPP user by PPP Client-initiated user offline number of times.

In addition, also need to collect following network index information: charge time, the PPP user authentication request of asking the accounting server echo reply of current PPP number of users, PPP user logined duration to time, PPP user's online hours, the PPP user of certificate server echo reply.

The present invention assesses the network index information spinner of PPP access user's call quality and will gather from broadband server BAS the current broadband network system and Radius server.Because in the consumer wideband access procedure, each network equipment in the broadband network system will be stored the diverse network indication information in the access procedure, therefore when the user passes through the required network index information of system acquisition, can collect corresponding network index information by snmp protocol or syslog agreement or by the ftp agreement, concrete grammar is, on the network equipment that needs are gathered, realize a respective protocol corresponding server end, realize the respective protocol clients corresponding on the information acquisition module, the user end to server end sends request of data, carry in this request and require the network index information return, server end to receive after this request that the network index information with correspondence is back to client.Then, the equipment of being responsible for network index information is converted into network index is network index with the network index information of the gathering predetermined computation rule according to the required network index of assessment current network quality with described network index information translation.

For PPPOA user, owing to only there is the PPP stage, there is not the Discovery link setup stage, corresponding with it, when assessing this kind PPP access customer call quality, the network index of needs assessment comprises: LCP consults success rate, PPP user's success rate of surfing the Net, PPP consumer wideband access server call completing rate, PPP authentification of user success rate, PPP user's success rate of chargeing, PPP user on average logins duration, the average online hours of PPP user, the unusual drop rate of PPP user, PPP authentification of user affairs success rate, PPP authentification of user average response duration, PPP user's affairs success rate of chargeing, PPP user's average response duration that charges.

For PPPOE user, owing to have the PPPOE stage, so the network index of needs assessment also comprises current PPP online user number and PPPOE call successful rate.

At least one value in above-mentioned network index occurs unusual, thinks that then present network quality is unusual.

For network index is conformed to more with network environment, the present invention also sets credit rating for each network index, assesses according to credit rating.The establishing method of credit rating is set according to the network environment of locality, and the numerical value of varying environment lower network grade can be different.The network index of finding to calculate when the information analysis module thinks that then network quality is unusual not in the scope of described network index credit rating regulation, can the informing network administrative staff handle this moment.

In addition, for a catenet system, the network equipment may be a lot, usually need network is carried out differentiated control, in the network classification management, higher level's collecting device obtains network index information from this undernet equipment from subordinate's collecting device of this compass of competency, carries out the index conversion again after then the network index information of gathering being gathered.Thus, avoid all direct collection network indication informations from the network equipment of every grade of collecting device, reduce the system data flow, save resource.

Described PPP online user number is an online online PPP number of users of current time.As the preferred embodiments of the present invention, the current PPP number of users on PPP online user number=BAS Broadband Access Server, the higher limit of the credit rating of this network index is the PPP maximum number of user * 90% that BAS Broadband Access Server is supported; Lower limit is the mean value * 80% of current PPP online user number.

The PPPOE call successful rate is in the designated statistics duration, and PPP user is connected to the make a call ratio of number of times of BAS Broadband Access Server number of times and PPP user.It is to consult successfully in the PPP user PPPOE stage that PPP user is connected to the BAS Broadband Access Server number of times, and BAS Broadband Access Server sends the number of times of PADS message; PPP customer call number of times is that BAS Broadband Access Server receives that the user sends the number of times of PADI message.

Equally, PPPOE call successful rate=PPP user is connected to BAS Broadband Access Server number of times/PPP user number of times * 100% that makes a call in the present embodiment, and the higher limit of the credit rating of this network index is 100%, and lower limit is 95%.

It is in the statistics duration of appointment that LCP consults success rate, and LCP negotiation number of success and PPP user are connected to the ratio of BAS Broadband Access Server number of times.Obtain by following manner: LCP consults success rate=LCP negotiation number of success/PPP user and is connected to BAS Broadband Access Server number of times * 100%, the higher limit of this network index: 100%, and lower limit: 95%.

PPP user surfs the Net success rate in the designated statistics duration, PPP user's make a call ratio of number of times of number of success and PPP user of surfing the Net.PPP user's number of success of surfing the Net is that user profile (account number and password) correctly authenticates by certificate server, charges and also passes through smoothly in the authentication back, and PPP user is the number of times of accesses network normally; PPP customer call number of times is that BAS Broadband Access Server receives that the user sends the number of times of PADI message.

PPP user success rate=PPP user number of success/PPP customer call number of times * 100% that surfs the Net that surfs the Net, the higher limit of the credit rating of this network index is 100%, lower limit is 95%.

PPP consumer wideband access server call completing rate is in the designated statistics duration, and surf the Net number of success and PPP user of PPP user is connected to the BAS Broadband Access Server number of times and deducts the initiatively ratio of the number of times of on-hook of PPP user authentication failure and PPP user's charging failure and PPP user.PPP user's number of success of surfing the Net is that PPP user profile (account number and password) correctly authenticates by certificate server, charges and also passes through smoothly in the authentication back, and PPP user is the number of times of accesses network normally; It is to consult successfully in the PPP user PPPOE stage that PPP user is connected to the BAS Broadband Access Server number of times, and BAS Broadband Access Server sends the number of times of PADS message; PPP user authentication failure number of times is because usemame/password mistake or certificate server do not have the number of times of response; PPP user's charging failure number of times is for because customer charge exhausts or accounting server does not have the number of times of response; PPP user initiatively on-hook number of times is the number of times of user's active on-hook before successfully surfing the Net.

This network index obtains by following formula: PPP consumer wideband access server call completing rate=PPP user number of success/(PPP user be connected to BAS Broadband Access Server number of times-PPP user authentication failure number of times-PPP user's charging failure number of times-PPP user normally roll off the production line number of times) * 100% that surfs the Net.The higher limit of this network index is 100%, and lower limit is 95%.

PPP authentification of user success rate is meant in the statistics duration of appointment, and PPP authentification of user number of success and PPP authentification of user number of success add the ratio of PPP user authentication failure number of times.PPP authentification of user number of success is the number of times of PPP user profile (account number and password) by the correct authentication of certificate server; PPP user authentication failure number of times is because usemame/password mistake or certificate server do not have the number of times of response.Obtain according to the following equation: PPP authentification of user success rate=PPP authentification of user number of success/(PPP authentification of user number of success+PPP user authentication failure number of times) * 100%.The higher limit of credit rating is 100%, and lower limit is 95%.

PPP user's success rate of chargeing is meant in the statistics duration of appointment, and PPP user's number of success and PPP user number of success of surfing the Net of surfing the Net adds the ratio of PPP user's charging failure number of times.PPP user's number of success of surfing the Net is that PPP user profile (account number and password) correctly authenticates by certificate server, charges and also passes through smoothly in the authentication back, and PPP user can normally receive and dispatch the number of times of IP bag; PPP user's charging failure number of times is for because customer charge exhausts or accounting server does not have the number of times of response.

Computational methods: PPP authentification of user success rate=PPP user number of success/(PPP user surf the Net number of success+PPP user's charging failure number of times) * 100% that surfs the Net; The credit rating higher limit is 100%, and lower limit is 95%.

PPP user on average logins duration and is meant from PPP user and is connected to BAS Broadband Access Server to PPP user's successful average duration of surfing the Net.

Computational methods: PPP user on average logins duration=PPP user and logins duration sum/PPP user number of success of surfing the Net

PPP user logins duration=PPP user and receives that the charging response message moment-BAS Broadband Access Server sends the moment of PADS to PPP user

The higher limit of the credit rating of this index is 10 seconds.

The average online hours of PPP user are in the statistics duration of appointment, from surf the Net the successfully average duration of PPP user offline of PPP user;

Computational methods: the average online hours of PPP user=PPP online hours sum/PPP user number of success of surfing the Net.

The PPP user's online hours=PPP user offline moment-PPP user surfs the Net constantly;

Lower limit is the mean value * 80% of the average online hours of PPP user.

The unusual drop rate of PPP user is in the statistics duration of appointment, the surf the Net ratio of number of success of the unusual number of dropped calls of PPP user and PPP user.The unusual number of dropped calls of PPP user be PPP user in last network process by artificial factor or equipment fault (service can't be provided) in addition reason cause the improper number of times that goes offline; PPP user's number of success of surfing the Net is the number of times that PPP user's successful access network connects.
