Description

Acquisition methods and the system of DSL maximum traffic data rate

Technical field

The present invention relates to the communication technology, acquisition methods and the system of especially a kind of DSL (DSL) maximum traffic data rate.

Background technology

Along with the development of the business demands such as high speed internet application, HD video, the lifting of Access Network speed is extremely urgent.The Mainstream Broadband access technology that current public user is used is still ADSL (Asymmetric Digital Subscriber Line) (the Asymmetrical Digital Subscriber Loop based on copper cable, ADSL) with second generation ADSL standard expansion (ADSL2plus, ADSL2+), support that surpass/very-high-bit-rate digital subscriber loop (Very high speed Digital Subscriber Line, the VDSL2) technology of higher rate is also progressively ripe.Along with the development of light entering and copper back, the optical fiber based on the access of EPON (Passive Optical Network, PON) light is to X(fiber to the x, FTTX) progressively expansion of application, especially fiber entering household (FTTH) has become trend.And for being difficult to fiber entering household transformation or being limited by the region of improvement cost pressure, by optical cable laying, to the node that approaches user, indoor lead-in still utilizes the access of original copper cable DSL (DSL) technology, also can promote rapidly speed.But, because copper cable access technology is limited by access distance and line to crosstalking, how can know rapidly the maximum traffic data rate that user section DSL circuit actual deployment can steady in a long-term provide in using, become the problem that operator is concerned about very much.

Realizing in process of the present invention, inventor finds that prior art at least exists following problem:

It is Digital Subscriber Line Access Multiplexer (the Digital Subscriber Line Access Multiplexer gathering based on local side that current conventional DSL speed is estimated mode, or PON multitenant unit (Multi Dwelling Unit DSLAM), MDU) " maximum achievable rate " parameter providing, mainly be shown towards ADSL and ADSL2+(following table: ADSL/ADSL2+), do not consider the situations such as the online rate of subscriber's line, and do not consider the Deta bearer expense feature of various DSL technology, lack monitoring for quality and the long-time stability of circuit simultaneously, what therefore draw estimates the speed accessible maximum link building rate of this circuit under present case often, actual in the time that scale is opened in high line activation rate situation, multi-user's circuit is reached the standard grade simultaneously and can be caused the cross talk effects between DSL line pair to strengthen, especially between 25 pairs of lines in base unit copper cable pair, for high speed VDSL2 of new generation, cross talk effects is more obvious, add environmental interference, stable traffic data rate also can significantly decline thereupon.As shown in Figure 1, for the existing conventional DSL evaluation scheme configuration diagram that tests the speed, wherein, DSL parameter acquisition platform is responsible for gathering DSL operational factor, mainly comprise current link building rate, maximum achievable rate etc., be then uploaded to DSL speed Prediction System and carry out speed assessment.

In addition, conventional DSL speed is estimated mode and is not often considered the carrying expense of different DSL technology, the speed of therefore estimating be difficult to reflection wired right practical stability traffic data rate.For example, general DSL speed is estimated the maximum achievable rate parameter that mode only provides according to equipment, is the speed based on physical layer.Because ADSL/ADSL2/ADSL2+ adopts asynchronous transfer mode (Asynchronous Transfer Mode, ATM) bearing mode, its protocol overhead is about 10%-15% left and right, and VDSL2 generally adopts point-to-multipoint (Point To Multipoint, PTM) bearing mode, its protocol overhead is in 3%-5% left and right.Therefore reality need to be considered the expense of this part in the time of carrying user service data, on the basis of estimating speed, deducts the speed of expense again, leaves certain surplus.

Comprehensive above-mentioned situation, the traffic data rate that existing DSL speed Prediction System is opened usually above practical stability stablizing the discreet value of traffic data rate, as assessed for VDSL2, error is larger, bring illusion to the granting of front-end business department service, often cause the unstable of speed-raising, cause user's complaint, also increase the pressure of maintenance department simultaneously.
