Description
Technical field
The present invention relates to peer-peer protocol (PPP) technology in the communication system, relate in particular to a kind of point-to-point asynchronous negotiating method and device.
Background technology
Ppp protocol is a kind of important protocol of link layer, supports the negotiation of multiple network layer control protocol.On distributed apparatus, ppp link generally is present on the interface board.When distributed apparatus is held consultation by ppp link and other network equipment, if in negotiations process, need to apply for available resources, and these available resources are by unified management on the master control borad, as Internet protocol (IP) address pool management in authentication and authorization charging (AAA) module, so, interface board just must be by communication between plate to master control borad application available resources.Usually, interface board mainly is divided into following two kinds to the mode of master control borad application available resources: the method for synchronization and asynchronous system.
The method of synchronization is meant, after interface board is received the message of negotiation request of sending the opposite end, if find and then to send the available resources request to master control borad to master control borad application available resources by resolving, and just can carry out subsequent treatment after must waiting until the master control borad echo reply.That is to say that before the master control borad echo reply, interface board must be in wait state always, and can not carry out other any processing.But,, therefore, in the process that interface board is waited for, will inevitably block the processing of follow-up other message, thereby cause the reduction of device processes performance because there is certain time delay in communication itself between plate.
Asynchronous system is meant that interface board need not to wait for, continues to finish the respective handling of this negotiation packet after sending the available resources request to master control borad, by the time behind the master control borad echo reply again the mode by asynchronous readjustment trigger negotiation again.Like this, just can avoid, reduce the device processes Effect on Performance owing to follow-up other message is blocked in this negotiation.But, because interface board does not obtain available resources after sending the available resources request, therefore, interface board must complete successfully sending the negotiations process of being carried out asynchronous request back, have only the master control borad echo reply of waiting until and opposite end to initiate message of negotiation request again and trigger negotiation again, just can complete successfully this negotiations process.
That is to say that existing this asynchronous negotiation mode need be carried out the secondary negotiation, has prolonged negotiations process, has increased the time of handling through consultation.And this asynchronous negotiation mode can't satisfy some peculiar demands of applications.Such as linking for dial-up, if after the failure of address negotiation for the first time, the opposite end does not have to initiate again newer calling, so, this dial-up will can't be set up forever.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is described in further detail the present invention.
Describe as seen by background technology, though existing point-to-point asynchronous negotiating method can not cause obstruction to follow-up other message,, complete successfully this asynchronous negotiation, then need to carry out secondary and handle through consultation, prolonged the time of handling through consultation.
In order to overcome the problems referred to above, the invention provides a kind of point-to-point asynchronous negotiating method.Referring to shown in Figure 1, this method mainly may further comprise the steps:
Step 101: receive the message of negotiation request that the ppp link opposite end sends over.
Step 102: the message of negotiation request of receiving is resolved, judge whether to carry out asynchronous process, if desired, then execution in step 103; Otherwise, handle according to the existing protocol flow process.
Step 103: send asynchronous request, and preserve the message of negotiation request of receiving.
Having preserved after described needs carry out the message of negotiation request of asynchronous process, can continue to handle follow-up other message, asynchronous negotiations process this time finishes and need not by the time.
Step 104: after receiving asynchronous request response, the message of negotiation request of preserving is carried out dissection process again.
As seen, in Fig. 1, receive need carry out the message of negotiation request of asynchronous process after, preserve the message of negotiation request of being received, like this, receive asynchronous request response by the time after, just can directly handle the message of negotiation request of preserving, and need not to wait for that the opposite end initiates message of negotiation request again and carry out secondary and consult, thus shortened negotiations process, reduced the asynchronous time of handling through consultation.And, after having preserved message of negotiation request, can continue to handle follow-up other message, and need not to wait for, thereby avoid this to consult to block the situation generation of follow-up other message, improved the device processes performance.
In order to support the asynchronous negotiating method among the present invention, need carry out asynchronous expansion to existing P PP state machine.Such as, in RFC 1661, on the ppp state machine basis of definition, increase RCRW+, RCRW-, RARR and these several incidents (events) of WTO; Simultaneously, increase wat, iars, rrc and these several actions (actions) of unw.Wherein, the definition of the events of increase and actions ginseng is shown in Table 1.
| Events | ?actions |
| RCRW+＝Receive-Configure-Request-Wait with?a?new?async?request | ?wat＝Waitting |
| RCRW-＝Receive-Configure-Request-Wait without?a?new?async?request | ?iars＝Increase-Async-Request-Sequence |
| RARR＝Receive-Async-Request-Response | ?rrc＝Recall-Receive-Configure-Request |
| WTO＝Waitting-Timeout | ?unw＝Unwaitting |
Table 1
Respectively the incident of above-mentioned increase and the definition of action are described below.
Wherein, RCRW+ represents to receive and need carry out the message of negotiation request of asynchronous process, and has sent asynchronous request; RCRW-represents to receive the message of negotiation request that need carry out asynchronous process, and does not send asynchronous request; RARR represents to receive effective asynchronous request response; WTO represents packet buffer protection timer expiry; Wat represents asynchronous etc. pending, and promptly the current message of negotiation request of buffer memory starts packet buffer protection timer, and with the set of asynchronous process flag bit; Iars represents that asynchronous request sequence number increases progressively; Rrc represents that the message of negotiation request with buffer memory is reentered into state machine and carries out dissection process; Unw represents to cancel asynchronous etc. pending, promptly discharges the message of negotiation request of current cache, deletion packet buffer protection timer, and the asynchronous process flag bit resetted.
For the purpose of clear more, below the asynchronous process of handling through consultation that adopts ppp state machine expanded definition is elaborated.Referring to shown in Figure 2, the asynchronous process of handling through consultation in the present embodiment mainly may further comprise the steps:
Step 201: receive message of negotiation request, the message of negotiation request of receiving is put into state machine handle.
Step 202: resolve the message of negotiation request of receiving, judge whether to carry out asynchronous process, if desired, then execution in step 203; Otherwise, produce the RCR+/RCR-incident, carry out respective handling according to the definition of standing state machine.
Step 203: judging whether needs to send asynchronous request, and if desired, then execution in step 204; Otherwise, execution in step 205.
Step 204: send asynchronous request, produce the RCRW+ incident.After state machine is received the RCRW+ incident, carry out iars asynchronous request sequence number is added one, and carry out wat and carry out asynchronous etc. pendingly, promptly the message of negotiation request received of buffer memory starts packet buffer protection timer, and with the set of asynchronous process flag bit.Then, execution in step 206.
Step 205: produce the RCRW-incident, asynchronous request sequence number remains unchanged, and continues to wait for.
Such as, on distributed apparatus, when interface board was received the message of negotiation request of the request distributing IP address that the opposite end sends over first, interface board then sent the asynchronous request of an application IP address resource to master control borad, and produce a RCRW+ incident, carry out asynchronous etc. pending.Afterwards, when interface board was received the IP address assignment request that the opposite end sends over once more, if previous request is not also finished, and the packet buffer timer do not have overtimely yet, then produces a RCRW-incident, need not send a new asynchronous request again.
In addition; if interface board is after the asynchronous request of sending an application IP address resource to master control borad; receive the message of negotiation request that the opposite end sends over again; and find to need to apply for new resource by resolving, so, interface board then sends the asynchronous request of a new application resource to master control borad; and discharge the message of negotiation request of original buffer memory; preserve the message of negotiation request of this time receiving, and asynchronous request sequence number is added one, restart packet buffer protection timer.
Wherein, interface board is by checking whether the asynchronous process flag bit had sent identical asynchronous request before judging, if then determine not need to send asynchronous request again; Otherwise, determine to need to send asynchronous request.
Step 206: receive asynchronous request response.
Step 207: judge whether the asynchronous request response of receiving is effective, if effectively, then execution in step 208; Otherwise, execution in step 209.
Wherein, describedly judge whether asynchronous request response effectively comprises: judge whether the pairing asynchronous request sequence number of asynchronous request response is consistent with the asynchronous request sequence number of current preservation, if the sequence number unanimity determines that then asynchronous request response is effective; Otherwise, determine that asynchronous request response is invalid.
Step 208: produce the RARR incident, carry out action rrc, the message of negotiation request of buffer memory is reentered into state machine carries out dissection process, delete packet buffer protection timer simultaneously, and the asynchronous process flag bit is resetted.Then, jump out this flow process.
Described message of negotiation request with buffer memory is reentered into state machine carries out dissection process and is meant, returns execution in step 202, and produces different RCR incidents (RCR+/RCR-/RCRW+/RCRW-) according to the difference of analysis result.
Step 209: discharge the resource of being distributed in the asynchronous request response.
In addition, if behind packet buffer protection timer expiry, do not receive asynchronous request response yet; then produce the WTO incident, directly carry out cancellation and wait for operation unw, discharge the message of negotiation request of buffer memory; the deletion packet buffer is protected timer, and the asynchronous process flag bit is resetted.
Fig. 3 shows the state transition diagram that adopts ppp state machine expanded definition.Wherein, abscissa is represented state (state), and ordinate presentation of events (events), the intersection point of horizontal ordinate are represented state machine after receiving certain incident under certain state, needs action of carrying out and the state that needs conversion.Concrete definition about each state and events can repeat no more here with reference to RFC 1661 agreements.
Italicized item shown in Figure 3 is the part of making change in the embodiment of the invention.Mainly increased these several incidents of RCRW+, RCRW-, RARR and WTO among Fig. 3, and increased processing these several incidents.
As seen from Figure 3, if state machine is replied (Ack-Rcvd)/send (Ack-Sent)/(Opened) state of consulting successfully of replying to receive the RCRW+ incident consulting to stop (Stopped)/send request (Req-Sent)/receive, then can carry out iars and wat and operate; If state machine receives the RCRW-incident at the Stopped/Req-Sent/Ack-Rcvd/Ack-Sent/Opened state, then only carry out the wat operation, do not carry out the iars operation.
And state machine only can be moved to this two states of Req-Sent/Ack-Rcvd after receiving the RCRW+/RCRW-incident, only just can carry out asynchronous wait under this two states.When state machine during, need to carry out pending unw such as cancellation from Req-Sent/Ack-Rcvd state transition to other states except that this two states.
If state machine promptly receives the RARR incident at the Req-Sent/Ack-Rcvd state in the process of asynchronous wait, then carry out rrc, the message of negotiation request of buffer memory is reentered into state machine carries out dissection process.If state machine receives the effective negotiation request (RCR+) of receiving/receive invalid negotiation request (RCR-)/receive to stop request (RTR)/WTO incident at the Req-Sent/Ack-Rcvd state, then carry out pending unw such as cancellation.
In addition, owing to carry out the unw processing when state Req-Sent/Ack-Rcvd is moved to other states, deleted packet buffer protection timer, therefore, other states outside Req-Sent/Ack-Rcvd can not receive the WTO incident.
Machine definition of the ppp state of expansion shown in the employing table 1 and state transition diagram shown in Figure 3 are realized point-to-point asynchronous negotiations process, can reduce the point-to-point asynchronous time of handling through consultation, improve the ppp negotiation treatment effeciency, and, can also guarantee that the device processes performance is unaffected.
In addition, on ppp state machine extension mechanism provided by the present invention basis, can also do further expanding according to other application demand.
Correspondingly, the present invention also provides a kind of point-to-point asynchronous consulting device.Referring to shown in Figure 4, this device mainly comprises: message process unit and message are preserved the unit.Wherein,
Message process unit, be used for receive need carry out the message of negotiation request of asynchronous process after, send asynchronous request, and the message of negotiation request of receiving is kept at message preserves in the unit; And, after receiving asynchronous request response, message is preserved the message of negotiation request of preserving in the unit carries out dissection process again.
Referring to shown in Figure 5, this device can further comprise: packet buffer protection timer;
Described message process unit is further used for, and starts packet buffer protection timer when preserving message of negotiation request, if do not receive asynchronous request response yet behind this timer expiry, then discharges message and preserves the message of negotiation request of being preserved in the unit.
Wherein, described message process unit can be further used for, and whether has sent identical asynchronous request before judging after receiving the message of negotiation request that need carry out asynchronous process, if, and described packet buffer protection timer is not overtime, then continues to wait for asynchronous request response; Otherwise, send asynchronous request, and the message of negotiation request of receiving be kept in the message preservation unit.
And, can be further used for, judge after receiving asynchronous request response whether this asynchronous request response is effective, if effectively, then message is preserved the message of negotiation request of preserving in the unit and carry out dissection process again; Otherwise, discharge the resource of being distributed in this asynchronous request response.
