Description
Technical field
The present invention relates to the communication technology, especially a kind of DSL（DSL）The acquisition of maximum traffic data rate
Method and system.
Background technology
Apply with high speed internet, the development of the business demand such as HD video, the lifting of access network speed is extremely urgent.
The Mainstream Broadband access technology that current public user is used still is the ADSL based on copper cable
（Asymmetrical Digital Subscriber Loop, ADSL）With second generation ADSL standard extensions（ADSL2plus,
ADSL2+）, support super/very-high-bit-rate digital subscriber loop of higher rate（Very high speed Digital
Subscriber Line, VDSL2）Technology is also progressively ripe.With the development of light entering and copper back, based on EPON
（Passive Optical Network, PON）The optical fiber of soft exchange is to X（Fiber to the x, FTTX）Using progressively expanding
Greatly, especially fiber entering household（FTTH）Turn into trend.And for being difficult to fiber entering household transformation or being limited by improvement cost pressure
The region of power, by optical cable laying to the node close to user, indoor lead-in still utilizes original copper cable DSL（DSL）
Technology is accessed, and speed can also be lifted rapidly.But, because copper cable access technology is limited by access distance and line to crosstalk,
How the maximum traffic data rate that can be provided steadily in the long term in the DSL line actual deployment use of user section is provided rapidly,
As operator's very concern.
During the present invention is realized, inventor has found that prior art at least has problems with：
It is the Digital Subscriber Line Access Multiplexer gathered based on local side that conventional DSL speed, which estimates mode, at present（Digital
Subscriber Line Access Multiplexer, DSLAM）Or PON multitenant units（Multi Dwelling Unit,
MDU）" maximum achievable rate " parameter provided, is mainly directed towards ADSL and ADSL2+（Hereinafter referred to as：ADSL/ADSL2+）,
Not situations such as not considering the online rate of subscribers' line, and the Deta bearer expense feature of various DSL technologies is not considered, simultaneously for line
The quality and long-time stability on road lack monitoring, thus draw estimate speed be often under present case the circuit it is accessible
In the case of maximum link building rate, actual line activation rate high when scale is opened, multi-user's circuit is reached the standard grade simultaneously can cause between DSL lines pair
Cross talk effects increase, between 25 pairs of lines pair especially in base unit copper cable, for the high speed VDSL2 of a new generation, crosstalk shadow
Sound is become apparent, and adds environmental disturbances, and stable traffic data rate can be also remarkably decreased therewith.As shown in figure 1, being existing normal
DSL tests the speed evaluation scheme configuration diagram, wherein, DSL parameter acquisition platforms are responsible for gathering DSL operational factors, main bag
Current link building rate, maximum achievable rate etc. are included, DSL speed Prediction System is then uploaded to and carries out rate evaluation.
In addition, conventional DSL speed estimates mode and does not often consider the carrying expense of different DSL technologies, therefore estimate
Speed be difficult to reflection wired pair of practical stability traffic data rate.For example, general DSL speed estimates mode according only to setting
The standby maximum achievable rate parameter provided, is the speed based on physical layer.Because ADSL/ADSL2/ADSL2+ is passed using asynchronous
Defeated pattern（Asynchronous Transfer Mode, ATM）Bearing mode, its protocol overhead about in 10%-15% or so, and
VDSL2 typically uses point-to-multipoint（Point To Multipoint, PTM）Bearing mode, its protocol overhead is in 3%-5% or so.
Therefore it is actual to need to consider the expense of this part when carrying user service data, i.e., subtracted out again on the basis of speed is estimated
The speed of pin, leaves certain surplus.
Summary situation, existing DSL speed Prediction System is to stablizing the discreet value of traffic data rate usually above real
The stable traffic data rate opened in border, error is bigger if being assessed for VDSL2, is brought to front-end business department service granting
Illusion, often results in the unstable of speed-raising, triggers the complaint of user, while also increasing the pressure of maintenance department.
