Description
Technical field
The present invention relates to the matching process and the equipment of the COS in the network, the coupling that particularly relates to the COS by the point-to-point protocol on the Ethernet provides the matching process and the equipment of service for the user.
Background technology
Point-to-point protocol on the Ethernet (PPPoE) belongs to link layer protocol, its major function is the connection that point-to-point is provided on Ethernet, set up the PPP session, and the method for encapsulation PPP information bag, having realized setting up the function of PPP(Point-to-Point Protocol) session to a plurality of purposes on shared ethernet, is the complementarity agreement that ppp protocol is used in wider scope.The PPPoE agreement provides a kind of ability of utilizing bridging device to insert the far-end access concentrator for main frame, under this model, each main frame can be with its ppp protocol stack, what offer the user is a common user interface, this make access control, charging and other service all be at single the user's rather than at site or main frame.Will set up point-to-point connection on Ethernet, each PPP session must be known the Ethernet hardware address of opposite end, must set up unique Session ID.PPPoE solves this two problems by the discovery stage:
PPPOE is divided into two stages, and first stage is the discovery stage, is used for obtaining the Ethernet hardware address of opposite end and is the SessionID (session identification) of host assignment PPPOE, and second stage is the PPP session stage.The payload in discovery stage (Payload) is each TAG (option) of PPPoE.The PPP session stage is encapsulated in the PPP message in the ethernet frame as the payload of PPPoE and transmits.
The stage of wherein finding can be divided into four steps:
The first step: main frame is broadcasted a PADI (PPPoE find stage initialization) bag in this Ethernet, and the service type information of main frame being wanted to obtain in this bag is included in name and is called in the attribute of Service-Name (COS).The value of this attribute must be a character string with the UTF-8 of nonblank character end.When its length field is 0, show that any service can be received by main frame.
Second step: all access concentrators in the Ethernet are after receiving this initialization bag, the requested service wherein and the service that oneself can provide are compared, wherein main frame provides the access concentrator of this service to beam back PADO (PPPoE finds that the service in stage provides message) bag for this reason, can not provide the concentrator of this service can not send out the PADO bag.
The 3rd step: main frame may be received the PADO bag of a plurality of concentrators, main frame is by the content of PADO, from the service available access concentrator of beaming back the PADO bag, select one according to certain condition, and beam back a conversation request bag PADR (PPPoE find stage request message) (non-broadcasting) to it, in this bag once more with the information of conceivable service be included in the Service-Name attribute.
The 4th step: chosen access concentrator just begins to prepare to enter the PPP session stage after receiving conversation request bag PADR.It can produce this section pppoe session of a session identification with unique sign it and main frame.And this specific session identification is included in session confirms to send back to main frame among the bag PADS (PPPoE finds the session confirmation message in stage), if there be not wrong the generation, just enter into the PPP session stage, and if main frame is receiving there is not the wrong PPP session stage that takes place also to enter into after bag is confirmed in session.
In the prior art, PPPoE user passes through the Service-Name attribute the needed Service Notification access concentrator of user with needed service in PADI and PADR message, access concentrator is after the request of receiving, compare with the own service that can provide, if can provide such service just the user to be responded, otherwise do not respond user's access request.Especially, if user's Service-Name is empty, then unconditionally responds the user and insert request; If user's Service-Name is not empty, then inquire about all Service-Name that dispose on the access device, if the inquiry failure, then refusal is responded.
There is following unreasonable part in the prior art, can not satisfies the needs of practical application fully:
1. insert to the access concentrator request with the Service-Name attribute of null value as if the user, prior art can the unconditional user of response be asked, and allows the user to insert.Because the number that access concentrator allows to insert is limited, if a large amount of users inserts with the Service-Name attribute of null value, then certainly will cause among the follow-up user, can't access device even have the Service-Name attribute (user that clear and definite service request is promptly arranged) of non-NULL, can not satisfy for there being clear and definite COS requesting users that the application demand of access service is provided.
2. at user's Service-Name non-NULL, but do not have on the access concentrator under the situation of corresponding Service-Name, prior art can be refused the user is responded, this moment is not if dispose full Service-Name attribute on the access concentrator, be when having empty Service-Name attribute on the access device, the user also can't insert, and causes the access capability of equipment not make full use of.
3. in the prior art, the Service-Name that disposes on the access concentrator be its COS that can provide, but the service that the Service-Name that is disposed is on the access device to refuse to provide can not be provided, promptly can't realize the application demand that the user who asks some COS is refused to insert.

Embodiment
The scheme of the matching process of the COS of the point-to-point protocol on the Ethernet of the present invention expands the matching process of Service-Name in the PPPoE agreement, can dispose three kinds of situations and realize different demands respectively.Because user institute requested service type leaves in the Service-Name attribute as character string, after having determined that matched rule is accurate coupling or fuzzy matching, the coupling of the Service-Name that disposes is equal to the coupling of character string fully on user's Service-Name and the access device, when specific implementation, can determine the method for string matching as required, for example, have only and when the character string that is disposed on user and the access device is identical, just think coupling, or when a character string comprises another character string, think coupling.
According to the matching process of the COS of the point-to-point protocol on the Ethernet of the present invention, matching way can be divided into accurate matching way and fuzzy matching mode.
The basic procedure of matching process of the COS of the point-to-point protocol on the Ethernet of the present invention is described below in conjunction with Fig. 1.Access device receives conversation request bag PADR (PPPoE finds the request message in stage), in this bag, comprise the information of conceivable service.At first judge the matching way that is provided with on the access device, if the input of this matching way and equipment manager that matching way is set is inconsistent, then refusal is responded user's request.If the input of this matching way and equipment manager that matching way is set is consistent, judge further then whether the COS of carrying in the message that the user sends is empty.The method of described judgement matching way is that the character string of the matching way that will equipment manager be provided with on the character string that matching way is set and the access device of input compares definite.The described user of judgement with COS whether be empty result for not the time, refusal is responded user's request.If the result who judges is for being that promptly user's COS is a sky, then responds user's request.
Fig. 2 is the flow chart of the matching process of the present invention embodiment adopting accurate matching way.Access device receives conversation request bag PADR, in this bag, comprise the information of conceivable service.At step S1, judge the matching way that is provided with on the access device, the character string of the matching way that is provided with on the character string that matching way is set that is about to the equipment manager input and the access device compares and determines whether to be accurate matching way, if the result of judgement is for being then to enter step S2; If the result who judges thinks promptly that for not set matching way is the fuzzy matching mode, process enters step S4, the request of refusing user's.At step S2, judge whether the COS of carrying in the message of user's transmission is empty.If the result who judges is for being that promptly user's COS is a sky, then enters step S3.At step S3, judge whether N COS on the access device disposes completely, N is the maximum number of the configurable COS of access device.If, promptly do not have the COS that does not have configuration for not, then enter step S4, refusal is responded user's request.If, promptly wherein have the COS that does not have configuration for being, then enter step S6, respond.If promptly the user with COS be empty, when being set to accurately mate, equipment must exist the COS that not have to dispose just can respond the user.If the result that step S2 judges is for denying, if promptly user's COS is not empty, then enter step S5, compare with the COS that disposes on the matching unit, determine whether to exist the COS of coupling fully, if there is no the COS of mating fully, then enter step S4, refusal is responded user's request, otherwise enters step S6, responds.
Fig. 3 is the flow chart of the matching process of the present invention embodiment adopting the fuzzy matching mode.Access device receives conversation request bag PADR, in this bag, comprise the information of conceivable service.At step S11, judge the matching way that is provided with on the access device, the character string of the matching way that is provided with on the character string that matching way is set of equipment manager input soon and the access device compares and determines whether to be the fuzzy matching mode, if the result who judges is for being then to enter step S12; If the result who judges thinks promptly that for not set matching way is accurate matching way, process enters step S14, and refusal is responded user's request.At step S12, judge whether the COS of carrying in the message of user's transmission is empty.If the result who judges is for being, promptly user's COS be a sky, and then process enters step S16, and whether the COS that need not to dispose on the consideration equipment mates fully, unconditionally responds the user and inserts request.If the result who judges is for denying, the COS that is the user is not for empty, then enter step S13, not whether configuration is full for N the COS that the comparison query access device is disposed, if all configuration is full for user's COS, if configuration is not full, then enter step S15, further judge whether to exist the COS of coupling fully, the if there is no COS of mating fully at step S15, then enter step S14, refusal is responded user's request; If there is the COS of coupling fully, then enter step S16, respond user's request.
The method according to this invention outside setting accurate coupling or fuzzy matching mode, can increase the setting matching principle, and the matching principle of setting has forward matching principle and reverse matching principle.Under equal conditions, the result of these two kinds of matching principles is just in time opposite.Under the situation of reverse matching principle, if the COS of customer requirements is configured on access device, then refusal is responded user's access request.And under the situation of forward matching principle,, then respond this user's access request on access device if the COS of customer requirements has been configured, allow this user to insert.
The user can be provided with the combination of different matching principles and different matching way as required, therefore can make up multiple matching process.
Specify the matching process of an alternative embodiment of the invention below in conjunction with Fig. 4.Fig. 4 is the flow process that the present invention adopts the matching process of forward matching principle and accurate matching way combination.
Access device receives conversation request bag PADR, in this bag, comprise the information of conceivable service, at step S0, judge whether the matching principle that is provided with on the access device is the forward matching principle.If the result who judges, thinks promptly that the matching principle that is provided with on the equipment is reverse matching principle for not being, process enters step S4, the request of refusing user's; If the result who judges is for being then to enter step S1.
At step S1, further judge the matching way that is provided with on the access device, the character string of the matching way that is provided with on the character string that matching way is set of equipment manager input soon and the access device compares and determines whether to be accurate matching way, if the result who judges is for being then to enter step S2; If the result who judges thinks promptly that for not set matching way is the fuzzy matching mode, process enters step S4, the request of refusing user's.
At step S2, judge whether the COS of carrying in the message of user's transmission is empty.If the result who judges is for being then to enter step S3.If the result who judges then enters step S5 for not.
At step S5, judge whether access device exists the COS of coupling fully, if having, then with equipment on the COS that disposes mate, if the match is successful, then respond user's request, allow the user to insert, if coupling is unsuccessful, then refusal is responded user's request.Do not have the COS of coupling fully if judged result is an access device, then enter step S4, refusal is responded user's request.
At step S3, judge whether access device disposes the affair type that is at the expiration of a mourning period, if then the match is successful, enter step S6, respond user's request, allow the user to insert; If not, think that then it fails to match, enter step S4, the request of refusing user's.
Embodiment below in conjunction with Fig. 5 specifies the flow process that the present invention adopts the matching process of reverse matching principle and accurate matching way combination.
When setting on the equipment is reverse matching principle and accurate coupling combination,, judge whether the matching principle that is provided with on the access device is reverse matching principle at step S10.If the result who judges, thinks promptly that the matching principle that is provided with on the equipment is the forward matching principle for not being, process enters step S14, the request of refusing user's; If the result who judges is for being then to enter step S11.
At step S11, further judge the matching way that is provided with on the access device, the character string of the matching way that is provided with on the character string that matching way is set of equipment manager input soon and the access device compares and determines whether to be accurate matching way, if the result who judges is for being then to enter step S12; If the result who judges thinks promptly that for not set matching way is the fuzzy matching mode, process enters step S14, the request of refusing user's.
At step S12, judge whether the COS of carrying in the message of user's transmission is empty.If the result who judges is for being then to enter step S13.If the result who judges then enters step S15 for not, judge whether access device exists the COS of coupling fully, if exist, then with equipment on the COS that disposes mate, the match is successful, then enters step S14, refusal response user's request; If do not exist, then enter step S16, respond user's request.
At step S13, judge whether access device disposes the affair type that is at the expiration of a mourning period, if, then entering step S14, refusal is responded user's request, otherwise enters step S16, responds user's request, allows the user to insert.
