Fig. 2 is the method flow schematic diagram of the described a kind of dsl device dynamic strategy control of the embodiment of the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments content of the present invention is elaborated.
The method that the purpose of this invention is to provide a kind of dsl device dynamic strategy control; By this method, can realize the dynamic function such as distribution of DSL access interface rate dynamic configuration, two layers of dynamic OAM, multicast control table.
Shown in Fig. 1 and 2, the object of the present invention is achieved like this: a kind of roughly method of dsl device dynamic strategy control, carry out networking according to Fig. 1 mode; Support control protocol to realize between BRAS (Broadband RemoteAccess Server, Broadband Remote Access Server) equipment and the dsl device by expansion GSMPv3 agreement, and as the communication protocol between BRAS equipment and the dsl device; The server end that described BRAS equipment issues as control strategy, and according to the different application scene, this server end is issued to dsl device with control strategy, this dsl device implementation strategy is also returned the control result.
As shown in Figure 2, the method for the embodiment of the invention specifically comprises the following steps:
Because adopted above technical scheme, the present invention can realize dynamically adjusting the method for dsl device configuration.
Control protocol between BRAS equipment recited above and the dsl device is that (Internet Engineering Task Force IETF) realizes by expanding GSMPv3 (GlobalSwitch Management Protocol v3) agreement the Internet engineering work group.Wherein the main points of agreement are, must realize at IP layer or TCP/UDP layer, and so no matter between DSL and the BRAS Ethernet or ATM (asynchronous transfer mode, asynchronous transfer mode), can move this agreement.
Embodiment of the invention step 203 has four use scenes with top control framework correspondence:
(1) dynamically finds access topology when BRAS equipment, the QoS closely in the Access Network is provided control;
When the dsl device circuit initially got up or be synchronized to different speed again, dsl device produces and transmits a GSMP PORT UP EVENT message gave BRAS, comprises the specific parameter of DSL circuit in the message; When the circuit lossing signal of dsl device, dsl device produces a GSMP PORT DOWN message and also sends BRAS equipment to.
For the grade of service of expectation is provided, before user's login and access service, BRAS equipment need be recognized the initial attribute of the circuit of dsl device.
Particularly, when application scenarios that the dsl device port increases or reduces, this dsl device transmits a message that comprises the essential information of current dsl device by its report/execution functional module and gives BRAS equipment, described BRAS equipment is responded an acknowledge message and according to the negotiation result that receives message and step 202, the dsl device port speed is controlled.
(2) BRAS equipment is simplified the management of OSS system to business to the user and the business datum of dsl device transmission from OSS (Operational Support Systems, telecom business support system) system (as the Radius server).
When BRAS equipment receives the line topological information report message of new dsl device or follow-up user conversation foundation (PPP or DHCP) incident, this BRAS equipment can pass through GSMP (Global Standards Management Process, global standards management method) Port Management message and come the transmitting line configuration information to give dsl device.Described BRAS equipment can obtain such line configuring data from strategic server.
When user's business changes (as the change of strategic server triggering), BRAS equipment can upgrade line configuring.
When (3) optimizing Layer 2 Multicast replication mode on the AN (network node), this application scenarios can be controlled and manage to BRAS equipment.
(4) BRAS equipment is controlled, the power of test of access link as required; The remote loopback that this BRAS equipment can use the port administrative messag to come the requirement access node to carry out on the local loop is tested, and the result of loopback test can pass to BRAS equipment by the Port Management response message asynchronously by access node.
Employing the present invention can realize the dynamic-configuration adjustment in the dsl device running, thereby can support dynamic multicast control, emerging service functions such as dynamic bandwidth adjustment.
The above only is an illustrated embodiment of the present invention, should know that this can have many modification, this modification is not considered to break away from the spirit and scope of illustrated embodiment of the present invention, and the conspicuous modification of all such those of ordinary skills is within the scope of the appended claims involved.
