Abstract
The present invention provides a kind of exterior method and device for sealing in port of vectored system identification, and to solve the problems, such as that the prior art can not be identified to sealing in port outside vectored system, this method includes：Determine to be currently at the first port of link setup state in the set of vectors of DISLAM；The every other crosstalk coefficient in the port of link setup state to first port is calculated, obtains the corresponding crosstalk coefficient combination of first port；According to crosstalk coefficient combine in all crosstalk coefficients determine to seal in the outside port of set of vectors, the program is sealed in port to the set of vectors according to the crosstalk coefficient feature recognition of port link setup, so as to ensure that the error sampling message data that the port in the set of vectors produces in G.993.5 training process is all that the port inside vectored system is sampled, so can be more accurate when using error sampling message estimating crosstalk coefficient, the far end crosstalk noise that digital subscriber line access multiplex port is subject to preferably is offset.
Description
Technical field
The present invention relates to fixed network communication technical field, and end is sealed in more particularly to a kind of identification of vectored system is exterior
The method and device of mouth.
Background technology
FEXT (Far-End Crosstalk, far-end cross talk) is always xDSL (Digital Subscriber Line, number
Word subscribers' line) field problem, but increasingly mature with vectoring (vector quantization) technology, far-end cross talk is to xDSL
The puzzlement brought will greatly be mitigated and even be disappeared nearly.Vectoring technologies are by one or several from principle
On DSLAM (Digital Subscriber Line Access Multiplexer, digital subscriber line access multiplex)
All of the port is considered as a system, so the problem of far-end cross talk becomes an internal system.The Vectoring technologies of xDSL
When 2010 just the G.993.5 agreement of ITU-T has been issued by ITU-T standard.According to description G.993.5,
As long as pass through ES (Error Sample, error between each port inside circuit initial phase, DSLAM collection systems
Sampling) message, and VCE (Vectoring Control Entity, vector quantization controlled entity) is reported to, VCE utilizes ES
Message estimating crosstalk coefficient, matrix operation is carried out eventually through VP (vectoring processor, vector processor) chip,
By the crosstalk counteracting of internal system.In practical application scene, probably due to the mistake of wiring, some least a portion of ports may
Come from vectoring its exteriors, as shown in Fig. 1 in Figure of description, DSLAM1 and DSLAM2 are respectively two
Vectoring systems, the external Bundle2 of DSLAM1 external Bundle1, DSLAM2.Since routing is likely to occur on distributing frame
Mistake, some ports for Bundle1 occur have been connected to Bundle2, and some ports of Bundle2 are integrated into Bundle1, this
The outside port of vectoring systems is may be considered that by the port of wrong routing a bit.Due to the requirement of vectoring technologies,
The port for doing crosstalk counteracting must be the port in system, otherwise cause vectoring systems deviation occur to ES estimations, ES's
Deviation causes crosstalk coefficient deviation occur, the final accuracy for influencing internal system port far-end cross talk counteracting.

num.If port_id is less than max_port_num, follow-up process is continued to execute into S104；If port_id is more than
Max_port_num, illustrates that webmaster has been collected into all link setup states that are currently at that DSLAM is calculated and (has also referred to as been in
Showtime states) port crosstalk coefficient, crosstalk coefficient characterization is other all of the port as crosstalk sources to currently locating
Influenced in link setup status port, and webmaster adds up the corresponding crosstalk coefficient in port, the processing stream based on port
Journey terminates, it is necessary to enter flow S110 processing.
S104：Webmaster issues snmp (Simple Network Management Protocol, simple network management association
View) message obtains the link setup state of DISLAM ports and the transmission mode of xDSL circuits, and webmaster obtains port after the completion of the flow
Number build even chain state and line transmission pattern for the port of port_id.
S106：Whether algorithm engine is showtime states to the port and whether transmission mode is G.993.5 to sentence
It is fixed.
S107：Webmaster issues snmp message to DISLAM acquisition crosstalk coefficients.
After DISLAM receives message, the string for the port down direction that every other port to port number is port_id is calculated
Disturb coefficient real number and imaginary part.DISLAM calculates the modulus value of plural number according to real number and imaginary part, and value characterization is that other ports are made
For influence in showtime port of the crosstalk sources to currently to be obtained.By modulus value according to each end after the completion of DISLAM calculating
The data field that the form of two bytes of mouth is filled into message successively is reported to webmaster.Webmaster once obtains no more than 384*2
A byte.
S108：After algorithm engine receives the data of DISLAM responses, fext_coef+port_id* is saved the data in
The memory field of 384*2.
S109：Algorithm engine adds up the crosstalk coefficient of port_id ports received most 384 ports, note
The value is SUMport_id.Into S105.
S105：Port_id is increased by 1 by algorithm engine, into S103.Until all of the port poll finishes.
S110：Algorithm engine obtains the sum of most 384 crosstalk coefficients, is denoted as SUM0, SUM1 ... SUMmax_ respectively
Port_num. algorithm engine obtains the number of the vectoring ports in showtime at the same time, is denoted as showtime_port_
num。
S111：SUM0, SUM1 ... SUMmax_port_num are obtained into a subordinate ordered array according to sequence from small to large
SUM。
S112：Algorithm engine given threshold K%, the value are preferably 20%, inside the subordinate ordered array SUM first it is non-zero
Value starts, and according to sequentially screening from small to large, takes (showtime_port_num*K%) number destination interface.By these ends
Mouth is as outside port of the string as arrived the system.
S113：Webmaster includes the port out of screening in user's gui interface.
S1134：Flow terminates.
