Fig. 1 is please referred to, in turning the communication system of BRAS frameworks of control separation, terminal device 300 connects with Forwarding plane 100 It connects, Forwarding plane 100 and external network 400 or other-end equipment 300 can be passed through.
Simultaneously, Forwarding plane 100 can also pass through VXLAN (Virtual Extensible LAN, void to external network 400 Quasi- extension LAN) virtual channel communicated with control plane 200, terminal device 300 is sent with negotiation communication agreement Relevant message is sent to the control plane 200, or receives communication configuration information or forwarding table that control plane 200 issues .
Wherein, control plane 200 can by one or more based on X 86 processor (or based on data-handling capacity it is close Other types processor) communication equipment composition.Control plane 200 is connect with Forwarding plane 100, for receiving Forwarding plane 100 send with the relevant message of protocol negotiation, and to Forwarding plane 100 issue forwarding configuration or forwarding-table item.
Forwarding plane 100 can be based on network processing unit (Network Processor, abbreviation NP) by one or more Communication equipment forms.Forwarding plane 100 is connect with terminal device 300 and external public network respectively, for according under control plane 200 The forwarding of hair configures being forwarded to terminal device 300.
The prior art turns in the BRAS frameworks of control separation, and control plane 200 needs to be directed to when carrying out BRAS user managements Whether the terminal device 300 each reached the standard grade carries out the interaction of keep-alive (keepalive) message, kept with detection terminal equipment 300 Online.In keep Alive Packet interactive process, control plane 200 periodically sends keep-alive probe messages to terminal device 300, eventually End equipment 300 responds keep-alive response message after receiving keep-alive probe messages.If control plane 200 does not have within a certain period of time It receives terminal device 300 and is directed to the keep-alive response message that keep-alive probe messages are responded, then it is assumed that terminal device 300 is offline.
Since control plane 200 may be connect with multiple and different Forwarding plane 100, with each Forwarding plane of access 100 terminal device 300 increases, and control plane 200 needs the protection Message processing amount carried out also correspondingly to increase.A large amount of keep-alives The processing of message can occupy 200 a large amount of process resources of control plane, and huge pressure is brought to control plane 200.
Therefore the present embodiment proposes in a kind of communication system shown in Fig. 1, and control plane 200 is replaced by Forwarding plane 100 The scheme that keep Alive Packet interaction is carried out with terminal device 300, to mitigate the processing pressure of control plane 200.Below to this implementation The scheme that example provides is described in detail.
Fig. 2 is please referred to, Fig. 2 is a kind of flow of keep Alive Packet exchange method applied to Forwarding plane 100 shown in FIG. 1 Figure, below will be to the method includes each steps to be described in detail.
Step S110 carries out keep Alive Packet interaction by the Forwarding plane 100 and the terminal device 300.
In the present embodiment, control plane 200 is replaced to carry out keep Alive Packet with terminal device 300 by Forwarding plane 100 The pressure of keep Alive Packet processing can be shared each Forwarding plane 100 by interaction.In this way, can effectively mitigate control plane 200 processing pressure.
In a kind of specific implementation mode of the present embodiment, can control plane fixedly be replaced by the Forwarding plane 100 200 carry out the interaction of all keep Alive Packets, need not carry out additional negotiation.
In the present embodiment another kind specific implementation mode, according to different concrete application scenes, one may be only needed The interaction for dividing Forwarding plane 100 that control plane 200 is replaced to carry out keep Alive Packet.Or at the end for accessing a Forwarding plane 100 In end equipment 300, it is only necessary to be carried out instead of control plane 200 by Forwarding plane 100 for the terminal device 300 of a portion The interaction of keep Alive Packet, for example, can be directed to access 100 part special interface of Forwarding plane terminal device 300, be set as by Forwarding plane 100 replaces the interaction of the progress keep Alive Packet of control plane 200.
It is also possible to be the mistake for carrying out keep Alive Packet interaction by the control plane 200 and the terminal device 300 originally Cheng Zhong, such as according to the loading condition of control plane 200, needs to be taken over by Forwarding plane 100 according to the triggering of some concrete conditions Control plane 200 carries out the work of keep Alive Packet interaction with terminal device 300.
In these scenes, Fig. 3 is please referred to, the friendship of keep Alive Packet is if desired carried out by Forwarding plane 100 and terminal device 300 Mutually, then the Forwarding plane 100 first carries out step S210 before executing step S110.
Step S210 notifies the control plane 200 not carry out keep Alive Packet with the terminal device 300 and interact or stop working as The preceding keep Alive Packet interaction between the terminal device 300.
In the present embodiment, it just can replace controlling by the Forwarding plane 100 from being reached the standard grade the terminal device 300 Plane 200 carries out keep Alive Packet interaction.Can also be to carry out keep-alive report in the control plane 200 and the terminal device 300 In literary interactive process, the control plane 200 is taken over by Forwarding plane 100 and carries out protection message interaction with terminal device 300.
In the present embodiment, it for reaching the standard grade from the terminal device 300, just replaces controlling by the Forwarding plane 100 Plane 200 carry out keep Alive Packet interaction situation, the Forwarding plane 100 can the terminal device 300 ask reach the standard grade when, The control plane 200 is notified for the terminal device 300, and keep Alive Packet interaction is carried out by the Forwarding plane 100.
For example, in one embodiment, the Forwarding plane 100 can carry out special message with control plane 200 Interaction, to negotiate which side and terminal device 300 to carry out keep Alive Packet interaction by.
In another embodiment, due to determining that keep Alive Packet interaction executive agent belongs to one of communication protocol negotiation Point, the Forwarding plane 100 can pass through LCP (Link in the stage for negotiating to establish communication link with terminal device 300 Control Protocol, Link Control Protocol) Forwarding plane 100 described in message notifying.
Specifically, terminal device 300 first can send LCP messages to negotiate when request is reached the standard grade to the Forwarding plane 100 Establish communication link.The Forwarding plane 100 can be reported after the LCP messages that receiving terminal apparatus 300 is sent in the LCP It is inserted into a keep Alive Packet control field in text, and sets the keep Alive Packet control field to the first preset value.Then, will The LCP messages are sent to the control plane 200, so that the control plane 200 is according to the keep Alive Packet control field In the first preset value selection not with the terminal device 300 carry out keep Alive Packet interaction.
Alternatively, the Forwarding plane 100 can be reported after the LCP messages that receiving terminal apparatus 300 is sent in the LCP It is inserted into a keep Alive Packet control field in text, and sets the keep Alive Packet control field to the second preset value.Then, will The link control message is sent to the control plane 200, so that the control plane 200 is controlled according to the keep Alive Packet The second preset value selection in field does not carry out keep Alive Packet interaction with the terminal device 300.Wherein, first preset value 1 is could be provided as, second preset value could be provided as 0.
The situation of keep Alive Packet interaction is carried out by the Forwarding plane 100 and the terminal device 300 for needs, it is described Forwarding plane 100 also executes step S120.
Step S120, whether the keep Alive Packet between detection Forwarding plane 100 and the terminal device 300 interacts interrupts, If detecting, the keep Alive Packet between Forwarding plane 100 and the terminal device 300 interacts interruption, notifies the control plane 200 terminal devices 300 are offline.
The interaction of keep Alive Packet is periodically to send keep-alive probe messages by a wherein side, and another party is directed to the keep-alive Probe messages reply keep-alive response message, communicate so that two sides mutually confirm and maintain to communicate to connect.
In a kind of specific implementation mode of the present embodiment, periodically set from the Forwarding plane 100 to the terminal Standby 300 send keep-alive probe messages, and receive the terminal device 300 and be directed to the keep-alive response that the keep-alive probe messages are replied Message.
The Forwarding plane 100 detect do not receive the terminal device 300 transmission keep-alive response message it is lasting when It is long.If the duration reaches the first preset duration, during judgement is interacted with the keep Alive Packet between the terminal device 300 It is disconnected, notify the terminal device 300 of the control plane 200 offline.
For example, in the present embodiment, keep Alive Packet interaction cycle can be 60 seconds, first preset duration can be 3 A keep Alive Packet interaction cycle.If the Forwarding plane 100, which detects lasting 3 × 60 seconds, does not receive the terminal device 300 The keep-alive response message of reply, then it is assumed that the keep Alive Packet between the terminal device 300 interacts interruption, the terminal device 300 Offline, the Forwarding plane 100 sends notice to the control plane 200 and informs that terminal device 300 is offline.
In another specific implementation mode of the present embodiment, from the terminal device 300 periodically to the forwarding Plane 100 sends keep-alive probe messages.The Forwarding plane 100 receives the keep-alive that the terminal device 300 is periodically sent Probe messages, and for the keep-alive probe messages keep-alive response message is replied to the terminal device 300.
The Forwarding plane 100 detect do not receive the terminal device 300 transmission keep-alive probe messages it is lasting when It is long.If the duration reaches the first preset duration, during judgement is interacted with the keep Alive Packet between the terminal device 300 It is disconnected, notify the terminal device 300 of the control plane 200 offline.
If for example, the Forwarding plane 100 detects that not receiving the terminal device 300 within lasting 3 × 60 seconds actively sends out The keep-alive probe messages sent, then it is assumed that the keep Alive Packet between the terminal device 300 interacts interruption, and the terminal device 300 is Offline, the Forwarding plane 100 sends notice to the control plane 200 and informs that terminal device 300 is offline.
In the present embodiment, if carrying out keep Alive Packet interaction, control by the control plane 200 and terminal device 300 If plane 200 detects that terminal device 300 is offline, the 300 corresponding forwarding table of terminal device in the control plane 200 is deleted , and notify the Forwarding plane 100.For example, the control plane 200 can send one to the Forwarding plane 100 PADT messages make the Forwarding plane 100 discharge the communication session between the terminal device 300.
If keep Alive Packet interaction is carried out by the Forwarding plane 100 and user terminal, if the Forwarding plane 100 detects Terminal device 300 is offline, then deletes 300 corresponding forwarding-table item of the terminal device on the Forwarding plane 100, and described in notice The terminal device 300 of control plane 200 is offline, so that control plane 200 deletes the 300 corresponding forwarding table of terminal device .
Further, due between the Forwarding plane 100 and the control plane 200 probably due to will appear communicate it is different Often, for example, because there is packet loss in link obstructions.This 300 offline notice of terminal device that the Forwarding plane 100 can be caused to send can It can not reach the control plane 200.For example, because of link obstructions between the Forwarding plane 100 and the control plane 200 Packet loss occur, then offline notice is lost.Therefore in the present embodiment, the control plane 200 also by a kind of additional mechanism come Judge whether terminal device 300 is offline.
In general, the flow that the Forwarding plane 100 can obtain each terminal device 300 according to certain training in rotation period uses feelings Condition, and send traffic report message and report control plane 200.In the present embodiment, if the control plane 200 is default second The Forwarding plane 100 is not received in duration and is directed to 300 transmitted traffic report message of the terminal device, then it is assumed that the terminal Equipment 300 is offline, deletes the 300 corresponding forwarding-table item of terminal device.Wherein, second preset duration is more than described first Preset duration.
In this way, even if when communication between the Forwarding plane 100 and the control plane 200 occurs abnormal, the control It is offline that plane 200 processed can also perceive terminal device 300.
