Embodiment one
The present embodiment provides a kind of distribution method of VLAN resource under SDN framework, be applied to including client, forwarding end and
The communication network of server-side；The distribution method includes:
Receive the service order information for being derived from the client；
According to the service order information, it is configured to the virtual configuration unit of traffic assignments；
Receive the operating status of the client of forwarding end forwarding；
If the client is presence, the first data stream list is issued to the forwarding end, and allow message to be certified
Pass through, to authenticate the client；It is to be certified by rear, apply for VLAN resource, and issue the second data stream list to the forwarding
End；
If the client is off-line state, the VLAN resource is deleted, to nullify the business ordered.
The distribution method of VLAN resource under SDN framework provided by the present embodiment is retouched in detail below with reference to diagram
It states.The distribution method of VLAN resource is applied to communication network 1 as shown in Figure 1, the communication network 1 application under the SDN framework
Under the scene of SDN (Software Define Network software defined network), including client (CPE) 11, forwarding end 12,
Gateway 13 and server-side 14.In the present embodiment, with GPON (Gigabit Passive Optical Network: gigabit without
Source optical-fiber network) for system.The forwarding end 12 includes the ONT Optical Network Terminal (ONT121) with the client 11 communication connection
121 and with the ONT Optical Network Terminal 121 communication connection optical line terminal (OLT122) 122.In this present embodiment, the service
End 14 is the controller (SDN-C) of software defined network, which can be cloud, or entity services
Device.Configured with the virtual configuration unit for traffic assignments, including virtual optical line terminal 141 in the server-side 14
(vOLT) and in 3A network protocol chassis (AAA) 142 and broadband network Network Management Equipment business function all virtualizes 143
(vBNG).The 3A network protocol chassis is for authenticating the client.
In the present embodiment, when client orders a certain business, VLAN resource is dynamically distributed, can be offline in CPE terminal
In the case of distribute
When client nullifies a certain business, dynamic deletes VLAN resource, can delete in the case where CPE terminal is offline.
In the life cycle of customer service survival, CPE terminal is offline, does not influence VLAN resource online.
Fig. 2A is please referred to, flow diagram of the distribution method of VLAN resource under SDN framework in an embodiment is shown as.
As shown in Figure 2 A, under the SDN framework VLAN resource distribution method specifically includes the following steps:
S21 receives the service order information for being derived from the client.
For example, ordering a VIP business on IPTV.
S22 is configured to the virtual configuration unit of traffic assignments according to the service order information.
In the present embodiment, the virtual configuration unit includes virtual optical line terminal 141 (vOLT) and 3A network protocol
Business function all virtualizes 143 (vBNG) in frame (AAA) 142 and broadband network Network Management Equipment.
For example, AAA is the username and password of IPTV, vBNG is the set-top box of IPTV.
S23 receives the operating status of the client of forwarding end forwarding.
In the present embodiment, the operating status of the client includes online (UP) or offline (DOWN) of client.With
The online state of family network interface (UNI) is to interrupt (Admin Down) from controlled state to be transformed into controlled state connection (Admin
UP).The off-line state of User Network Interface (UNI) is to connect (Admin UP) from controlled state to be transformed into controlled state interruption
(Admin Down)。
It in the present embodiment, can also be using other OAM (Operation Administration Maintenance behaviour
Make management service) methods of connectivity checks judges the online, offline of client.
S24 issues the first data stream list to the forwarding end, and allow to be certified if the client is presence
Message passes through, to authenticate the client；It is to be certified to apply for VLAN resource by rear, and the second data stream list is issued to described
Forward end.
Fig. 2 B is please referred to, the flow diagram of S24 is shown as.As shown in Figure 2 B, the S24 specifically includes the following steps:
S241, online to the client, the online state (UP) of the User Network Interface of the ONT Optical Network Terminal reports
Extremely the optical line terminal (OLT), and the data message for issuing port (untag) of the ONT Optical Network Terminal (ONT) is beaten and is lacked
Label is saved, the COS value for representing the grade of service is distributed.Wherein, the online state of User Network Interface is from controlled state
It is disconnected to be transformed into controlled state connection.
In the present embodiment, the default label is default VLAN 0, and the default VLAN 0 is used for when not providing business,
Communication is provided for the client.
For example, default VLAN 0 is a common channel.
S242, vOLT issue OLT of first data stream list into the forwarding end, and message to be certified is allowed to pass through, OLT
Message to be certified is sent to 3A network protocol chassis (AAA), to authenticate the client.
In the present embodiment, first data stream list is that the controller (SDN-C) of the software defined network converts industry
Address table required for data packet of being engaged in.
In the present embodiment, described that message to be certified is allowed to include: 802.1x (EAPoL) mode, DHCP by way of
User's line identification means, PPP over Ethernet only allow the message in PPPoE discovery and session stage to pass through or fix
IP mode.
S243, to be certified by rear, business function all virtualization (vBNG) applications into broadband network Network Management Equipment
VLAN resource, vOLT issue the OLT of the second data stream list to the forwarding end by issuing port (untag).
In the present embodiment, VLAN resource is S+C VLAN resource, and wherein S is the money for identifying the optical line terminal
Source and C are the resources for identifying client.
In the present embodiment, second data stream list is that S+C VLAN resource issues flow table.
In the present embodiment, the OLT is turned VLAN by the communication protocol (i.e. OMCI) of the information interaction with ONT
It changes rule and is issued to ONT.User in uplink ethernet frame is voluntarily stamped VLAN Tag conversion for OLT by the VLAN transformation rule
For unique network side VLAN Tag；And opposite operation is executed in the downstream direction.
So far, vOLT controls ONT&OLT and completes the VLAN connection of client to vBNG.
In the present embodiment, business survives the phase, can control the rental period of S+C
Under normal circumstances, the phase is survived in business, S+C VLAN does not discharge, and tube terminal is not offline or online
But the rental period can also be controlled by vOLT, may exist two ways: configuring the permanent rental period, then CPE is online primary, i.e.,
S+C VLAN resource can be obtained for a long time, do not discharged.Alternatively, the rental period of one section of duration of configuration, then be less than in terminal offline time and rent
Phase does not discharge S+C VLAN resource, and offline time is greater than the rental period, discharges S+C resource, waits next terminal is online to redistribute again.
S25 deletes the VLAN resource if the client is off-line state, to nullify the business ordered.
Specifically, 3A network protocol chassis (AAA) deletes client, and notice vOLT deletes S+C VLAN resource.
The distribution method of VLAN resource is directed to the corresponding VLAN of business of user's application under SDN framework provided in this embodiment
It distributes no longer by the way of static configuration, but by the way of dynamically distributing.VLAN resource pool is configured in SDN controller,
The service disconnection or use that the dynamic allocation of VLAN resource are applied as user are carried out according to user's business that perhaps user applies
When business is no longer applied at family, VLAN resource discharges automatically, for the use of the business of other users or user.
