Authorization and Accounting authentication, authorization, accountings), RADIUS (Remote Authentication
Dial In User Service, remote customer dialing authentication system) etc..
In the embodiment of the present disclosure, CP connects a UP1, other UP such as UP2 by an open flows (openflow)
Then it is connected by open flows with UP1, with the backup of the session information (session) for realizing BRAS user between different UP.
Specifically, the main and standby relation of each Forwarding plane can be pre-configured with CP, such as UP1 is main Forwarding plane, UP2 is standby turns
Send out plane.Also, CP is configured to only to send session information to the UP1 being connected by open flows with the CP.From the UP1 to this
Other UP such as UP2 that UP1 is connected by open flows forward session information.With including but is not limited to the IP of user in session information
The user profile such as location, MAC Address, user name, customer flow statistical information, AAA information.The Forwarding plane of session information is received,
Hardware forwarding table item can be locally created according to received session information, realize the work(such as message forwarding, speed limit, traffic statistics
Energy.
The disclosure is introduced in control plane, the implementation method of Forwarding plane below by way of specific embodiment.
Fig. 2 shows the schematic diagram for turning the backup method of Forwarding plane in control separation according to the embodiment of the disclosure one.Such as Fig. 2
Shown, this method can apply to turn the first Forwarding plane in the system of control separation, and the system also includes and the first forwarding
The control plane and the second Forwarding plane, this method of plane commu connection can include：
Step 101, reception come from the session information of control plane；
Step 102, to the second Forwarding plane the session information is forwarded, so as to receive the second forwarding of the session information
Plane is according to backup Forwarding plane of the session information using itself as the first Forwarding plane.
In the present embodiment, corresponding each second Forwarding plane of the first Forwarding plane can be set in the control plane
It is set to the hot standby relation group of an IP user.Multiple IP address can be included in the hot standby relation group of IP user, wherein, first
IP address is the IP address of main Forwarding plane, and other IP address in addition to first IP address are for the IP of Forwarding plane
Location.Also, following configure is carried out in the control plane：The control plane is only flat to the first forwarding corresponding to first IP address
Face sends the session information, does not send session information to the second Forwarding plane corresponding to other IP address.
In the present embodiment, the Forwarding plane of session information can will be received from control plane as the first Forwarding plane,
The Forwarding plane of session information is received as the second Forwarding plane from Forwarding plane.
In one implementation, step 102 includes：By the backup path between second Forwarding plane,
The session information is forwarded to second Forwarding plane, the backup path is first Forwarding plane and described second turn
Send out the open flows connection between plane.
The detailed process of backup method is introduced using several examples below.
In one example, control plane is connected with the first Forwarding plane by open flows, the first Forwarding plane and each the
Two Forwarding plane are connected by open flows.In the control plane, by the configuration of the first Forwarding plane for main Forwarding plane, by each second
Forwarding plane is configured to standby Forwarding plane.Then, control plane can send the session letter of BRAS user to the first Forwarding plane
Breath.After first Forwarding plane receives the session information, can local according to the session information establish corresponding to hardware forwarding table
Etc..Also, the main Forwarding plane mark such as special identifier or field can be locally located in the first Forwarding plane, to represent
Itself it is main Forwarding plane.
In another example, the first Forwarding plane can also be each to being connected with first Forwarding plane by open flows
Second Forwarding plane forwards the session information., can be in local according to the session information after the second Forwarding plane session information

Open flows connection is crossed, the session can also be forwarded to the second Forwarding plane for not yet receiving the session information being connected with itself
Information.The second Forwarding plane of the session information is received, can the hardware forwarding according to corresponding to being established the session information in local
List item etc..Also, the second Forwarding plane can be identified in local by the standby Forwarding plane such as special identifier or field, carry out table
Show it itself is standby Forwarding plane.
It can be seen from above example, for each Forwarding plane, if some Forwarding plane receives a session information,
And it was found that the source of the session information is control plane, then the Forwarding plane can be set itself as main Forwarding plane.
If some Forwarding plane receives a session information, and it was found that the source of the session information is another Forwarding plane, that
Itself can be arranged to standby Forwarding plane by the Forwarding plane.
After realizing that forwarding separates with control, MANO (Management and Orchestration, manages composer)
The activestandby state of each Forwarding plane can be controlled according to link circuit condition.For example, under normal circumstances, main UP is UP1, standby UP is
UP2.Connectivity port state between UP1 and Layer 2 switch is arranged to up (reaching the standard grade) by MANO, by Layer 2 switch and UP2 it
Between connectivity port state be arranged to down (offline).If the UP1 as main UP breaks down, MANO hands over UP1 and two layer
Connectivity port state between changing planes is adjusted to down (offline), and the connectivity port state between Layer 2 switch and UP2 is adjusted
Whole is up (reaching the standard grade).
In the disclosure, after the reception of the first Forwarding plane comes from the session information of control plane, as relaying to second turn
Send out plane forwarding session information.After second Forwarding plane receives the session information, can according to the session information using itself as
The backup Forwarding plane of first Forwarding plane.So, because control plane reduces to the session information that Forwarding plane issues, have
Beneficial to the pressure for mitigating control plane, ensure the normal connection between control plane and Forwarding plane, reduce to CP performance bottles
The requirement of neck.
Further, due to being connected between control plane and main Forwarding plane by open flows, pass through between Forwarding plane
Open flows are connected, therefore the scheme that the backup of Forwarding plane is completed by IRF is substituted by the disclosure, and each Forwarding plane is being patrolled
Collect upper independent.In main fault of forwarding plane, whole Forwarding plane system will not be paralysed, and standby Forwarding plane can be played preferably
Backup acts on, and substitutes main Forwarding plane and carries out flow forwarding.
Fig. 3 shows the schematic diagram for turning the backup method of Forwarding plane in control separation according to the embodiment of the disclosure one.Such as Fig. 3
Shown, this method can turn the second Forwarding plane in the system of control separation, and the system also includes leading to the second Forwarding plane
Believe that the first Forwarding plane of connection, and the control plane with the communication connection of the first Forwarding plane, this method can include：
Step 201, reception come from the session information of the first Forwarding plane；
Step 202, according to backup Forwarding plane of the session information using itself as the first Forwarding plane.
In one implementation, step 202 includes：According to hardware forwarding table item corresponding to session information generation.
In one implementation, the system includes at least two second Forwarding plane, and methods described also includes：
Step 203, the second Forwarding plane for receiving session information not yet receive the of the session information at least one
Two Forwarding plane forward the session information.
In one implementation, step 201 includes：By first Forwarding plane and second Forwarding plane it
Between backup path, receive the session information from first Forwarding plane, the backup path is that the described first forwarding is flat
Open flows connection between face and second Forwarding plane.
In one implementation, step 203 includes：Receive the second Forwarding plane of session information by itself with not yet

Fig. 4 and Fig. 5 shows the applied field for turning the backup method of Forwarding plane in control separation according to the embodiment of the disclosure one
The schematic diagram of scape.In Fig. 4, the solid arrow between UP1 and UP2 represents backup path.In Figure 5, the list between CP and UP1
To the unidirectional dotted arrow between dotted arrow, and UP1 and UP2, the direction that session information (session) issues is represented.Such as
Shown in Fig. 4 and Fig. 5, in the case of CP limited capacities, CP connects a UP by an open flows (openflow), you can complete
Into session information (session) backup of the BRAS user between different UP.The disclosure can substitute the feelings that IRF is used between UP
Condition.UP backup is completed by IRF, each active and standby UP is a UP in logic.Forwarding plane in control separation is turned using the disclosure
Backup method carry out UP backup, each UP is independent.
As shown in Figure 4 and Figure 5, the backup method for turning Forwarding plane in control separation of the disclosure includes following characteristics：
1st, in normal turn of control isolating environment, for single UP1, CP can normally establish the ring of BRAS user authentication
Border.
2nd, UP main and standby relation is configured on CP.The main and standby relation is visible to user.Increase example on CP upper line interface
Such as following configuration, expression issues session to UP1 and UP2 respectively.
Such as：ip subscriber hot-backup-group 1.1.1.1 2.2.2.2.
3rd, configured in CP so that CP is when reality issues session to UP, just for first address, also
It is that UP1 address 1.1.1.1 issues session.Also, CP does not issue session to UP2 address 2.2.2.2.
To sum up, have the characteristics that in this example：1) CP only issues a session and reaches UP1；2) CP is not to UP2
Issue session；3) after UP1 receives the session of user, the hardware forwarding table item according to corresponding to being set session.
4th, when UP1 completes the processing of the 3rd step above, UP1 also needs to play a part of control information relaying.I.e.：UP1 is needed
By the session of the user sent under CP, the backup path between UP1 and UP2 is continued through, is synchronized on UP2.
Wherein, it is TCP connections between UP1 and CP, is TCP connections between UP1 and UP2, can be forwarded with direct repeating system.
Also, the connection of a peer-to-peer in the form of TCP connections, can be established between UP1 and UP2 in advance.So,
User's session information can be mutually in step between UP1 and UP2.When to transmit session between UP1 and UP2, just at any time
This backup path can be enabled.
5th, UP1 is received after CP issues session, can be set oneself as main UP.UP2 receives the session of UP1 forwardings
Afterwards, oneself can be arranged to standby UP.So UP1 and UP2 just establish main and standby relation.
, can be whole by follow-up flow forward-path by MANO control during as being broken down for main UP UP1
It is switched to standby UP i.e. UP2.So, the switching of active and standby UP role is just completed.For example, MANO is by UP1 and Layer 2 switch example
As the connectivity port state between LSW is adjusted to down (offline), the connectivity port state between LSW and UP2 is adjusted to up
(reaching the standard grade).
6th, by above-mentioned mode, CP issues a session information to UP1, logical by the existing backup of UP1 and UP2
Road, complete the relaying transmission of user's session information.
7th, if more UP backup requirements.So, the session information of user can be to continue between follow-up UP
Hand on, accomplish 1：N backup.But the requirement to CP does not have any difference.
In the disclosure, CP issues a session information to UP1, by the existing backup paths of UP1 and UP2, completes to use
The relaying transmission of family session information, therefore, CP issue to UP1 and UP2 hot standby information, are the completions by UP1.
Because CP reduces to the session that UP is issued, CP pressure can be mitigated, reduce TCP disconnectings between CP and UP
Situation, reduces the requirement to CP performance bottleneck, and CP gets a promotion as control core, its stability.
Further, the scheme that the backup of Forwarding plane is completed by IRF is substituted by the disclosure, due to CP and main UP
Between connected by openflow, connected between main UP and standby UP by openflow, therefore each UP is logically independent.In master
During UP failures, standby UP can preferably play backup effect.
