Abstract

The invention discloses a strategy definition method for line access multiplexer of digital user comprising steps: positioning hierarchy of DSLAM in network; establishing strategy rule under the hierarchy according to the strategy description method; defining the strategy rule in DLSAM; when service or application enters the DLSAM, combining the defined strategy rule to service strategy at DSLAM hierarchy. Abstraction for strategy description and definition of DSLAM hierarchy can customize strategy for new service and application without changing DSLAM edition, thereby strategy definition can be quickly performed, which satisfies quick deployment for new service and application.

Description

Policy definition method in the digital subscriber line access multiplex

Technical field

The present invention relates to a kind of communication technology, specifically, relate to the policy definition method in a kind of digital subscriber line access multiplex.

Background technology

The broadband user has arrived the stage of high speed development at present, and number of users increases rapidly, and the speed to introduce of various new business in the network and application is also more and more faster simultaneously.The strategy that miscellaneous service and application requirements are done at this level of digital subscriber line access multiplex (DSLAM) also becomes increasingly complex, and this strategy is used for professional and uses desired various forms of parameter configuration.The function that DSLAM must possess quick strategy customization could satisfy quick deployment requirements professional and that use.

The policy definition method of DSLAM realization at present is to carry out stand-alone development according to concrete business and application, releases these business of support and applied version then.Policy definition lags behind business like this, and needs the regular hour perfect, finally causes DSLAM to support the hysteresis that these are professional and applied version is released.

Summary of the invention

Technical problem solved by the invention provides the policy definition method in a kind of digital subscriber line access multiplex, can customize the strategy that is fit to various new business and application fast.

Technical scheme is as follows:

Policy definition method in a kind of digital subscriber line access multiplex, step comprises:

(1) level of location DSLAM in network;

(2) according to the policing rule of tactful describing method formulation under described level;

(3) the described policing rule of definition in described DLSAM;

(4), the policing rule of described definition is combined into business game at the DSLAM level as professional or use when entering described DLSAM.

Further, in the step (3), the policing rule of described definition is kept in the policy library of policy definition system.

Further, in the step (4), the policing rule of policy definition module by having defined in the policing action interface interchange policy library; Described policy definition module is combined into business game with described policing rule, and by the policing action interface described business game is kept in the described policy library, and described business game is used to adapt to described business or the application that enters.

Adopt the present invention, strategy description and definition to the DSLAM level are carried out abstract, can under the situation that does not change the DSLAM version, customize out the strategy that is fit to new business and application, thus can carry out policy definition fast, to satisfy the quick deployment of new business and application.

Description of drawings

Fig. 1 is the structural representation of the Policy model among the DSLAM of the present invention;

Fig. 2 is the flow chart of the policy definition method among the DSLAM of the present invention;

Fig. 3 is the structural representation of the policy definition system among the DSLAM of the present invention.

Embodiment

General policing rule is described and is comprised three parts, i.e. incident (causing the network event of strategy), condition (causing the condition of policy action), action (action of strategy execution).DSLAM mainly is in Access Layer in network, be used to finish the function of two layers of forwarding, so the incident of this level mainly is exactly various Layer 2 datas streams, and the policing rule that defines in DSLAM mainly comprises condition and action two parts.Single condition and action are abstract to Layer 2 data Flow Policy condition and action, but these conditions and action can be combined to form complicated policing rule.

With reference to shown in Figure 1, a Policy model of this preferred embodiment is done detailed description.

The policing rule of one group of association forms a strategy group, and this strategy group can be finished simple business and application.A plurality of strategies are combined to form a strategy set, and this strategy set can be finished a complicated business and application.A plurality of strategy sets constitute a business game, are used to satisfy miscellaneous service and application need.

With reference to shown in Figure 2, the policy definition method among the DSLAM is done detailed description.

Step S201: the level of location DSLAM in network.

Step S202: the policing rule of formulating this level according to tactful describing method.

Step S203: this policing rule of definition in DLSAM.

Step S204: to new business be applied in the DSLAM level and carry out policing rule combination, be combined into the business game that adapts to new business and application according to the policing rule of definition.

Adopt said process can carry out policy definition fast, to satisfy quick deployment to new business and application.

With reference to shown in Figure 3, the course of work of tactful define system among the DSLAM is done detailed description.

Policy library among the DSLAM is exactly the database of conversation strategy and policing rule, and the policing action interface is used for connection strategy definition module and policy library.

Analyzed professional and be applied in the strategy that the DSLAM level needs and carry out abstract after, just can in DSLAM, define concrete policing rule, perhaps on existing policing rule, make up, form the business game that satisfies professional and application need, and this business game is kept in this policy library by the policing action interface.As new business or new the application when entering DSLAM, the business game of policy definition module by having defined in the policing action interface interchange policy library is to adapt to new business or new the application.

Because these policing rules are combinations of simple abstract rule, as long as DSLAM supports the simplest abstraction rule, the business game after just can supporting to make up, thus support concrete business and application requirements.Do not need to carry out targetedly the exploitation again of version, thereby arrive the quick definition strategy and dispose professional purpose.

Access control list (ACL) and service quality (QoS) are two kinds of strategies often using on DSLAM.ACL is simple relatively, generally is to control at two-layer protocol and data flow at this one deck of DSLAM, and the condition of the policing rule that ACL uses is exactly that head to two-layer protocol and data mates, and the action of policing rule is exactly to allow and abandon.And QoS is the relatively more complicated strategy of a class, contain the policing rule of data being handled again through behind the traffic classification, and traffic classification is the policy condition of this class qos policy, can use ACL to define, and this has just embodied the good durability of policy definition method.
