Description
Technical field
The invention belongs to a kind of method and realization system thereof of access communication service network, especially a kind of implementation method and system that is used to increase cabled digital subscribers feeder transmission bandwidth.
Background technology
The most frequently used broadband access technology is ADSL (ADSL) technology at present.State-of-the-art ADSL technology is standardized enhancing second generation ADSL technology (ADSL2+) in 2003, and this technology can provide descending maximum per second 24.4 megabits, the transfer of data broadband of up maximum per second 3.5 megabits in 5 kilometer range.
Why being called the ADSL, is because this technology has been used frequency multiplexing technique, on a telephone wire, transmits and receive data simultaneously.Like Fig. 9, shown in Figure 10, can find out that from spectrogram " ADSL Modem " up (transmission) link has used lower frequency range, and bandwidth is narrower; Descending (reception) link has used higher frequency range, and broader bandwidth, and is as shown in Figure 9." Digital Subscriber Line AM access module " is then opposite, and descending (transmission) link has used higher frequency range, and broader bandwidth; Up (reception) link has used lower frequency range, and bandwidth is narrower, and is shown in figure 10.
Current ADSL broadband access system comprises: connect " user computer " and " ADSL Modem " " ethernet line ", " ADSL Modem ", be connected " ADSL Modem " and " Digital Subscriber Line AM access module " " telephone wire ", belong to local side apparatus " Digital Subscriber Line AM access module ", be connected " Digital Subscriber Line AM access module " and higher level's " broadband service facility " " ethernet line ".As shown in Figure 1.
Wherein nucleus equipment is " the Digital Subscriber Line AM access module " that is configured in " ADSL Modem " of user's premises and belongs to local side.
" ADSL Modem " mainly is made up of " analog module ", " digital signal processing module " and " local interface module " three modules." analog module " can also further be subdivided into " circuit driver module " and " analog front-end module " two sub-module." digital signal processing module " can also further be subdivided into " Discrete Multitone is handled (DMT) module " and " Wide Area Network interface (WAN) module " two sub-module.On down direction; " analog module " accomplished the reception of telephone wire analog signals and filtering, variable gain amplification, process discrete sampling and quantification; Analog signal conversion is become digital sampled signal, give " digital signal processing module " and handle, accomplish the demodulation of Discrete Multitone signal at " digital signal processing module "; Wide area network signal (the normally ATM form) deblocking that demodulation is come out is dressed up original data signal; Submit to network " local interface module ", be encapsulated into suitable local network data signals transmitted (being generally Ethernet) form once more, offer computer and use at network " local interface module "; On up direction, (normally ethernet format) signal that network " local interface module " is sent computer here receives, and delivers to " digital signal processing module "; The valid data taking-up is packaged into wide area network (normally ATM) signal format; Carry out the Discrete Multitone modulation then, the signal after the modulation is given " analog module ", and digital signal is converted into analog waveform signal; Through after the filter amplifying processing, be driven on the telephone wire and export.Many companies provide the complete chip set solution of above-mentioned each module.

In order to obtain bigger transmission bandwidth, can the utilized bandwidth polymerization technique.The bandwidth polymerization is called channel binding or link aggregation technology again, is exactly with two or more multi-link bandwidth, offers independent one and connects use.
In the computer that adopts Windows operating system, allow two or more modulator-demodulators of configuration to link to each other, thereby the bandwidth of two or more telephone dialer circuit is used in polymerization with telephone wire.
For the situation that adopts ADSL to carry out broadband access, carry out the bandwidth polymerization and just be to use two telephone wires and two ADSL Modems, insert computer simultaneously through two network interface cards.ADSL bandwidth polymerization technique has used ATM backward channel multiplexing (IMA) technology of atm forum definition.It requires to participate in two multiplexing physical links and has identical message transmission rate and close delay performance.Adopt N bar ADSL2+ circuit to carry out the bandwidth polymerization, the descending data transfer bandwidth that can obtain maximum about per second 24N megabit, the up data transfer bandwidth that can obtain maximum about 3.5N megabit.
Another kind of different aggregation of bandwidth mode is called and connects cooperation.Each bar circuit of its not polymerization, but carry out single TCP/IP session through many circuits.A collaboration server is arranged in this Technology Need network, thereby the TCP session steadily is assigned on the different connection lines.Adopt N bar ADSL2+ circuit to connect cooperation, the descending data transfer bandwidth that can obtain maximum about per second 24N megabit, the up data transfer bandwidth that can obtain maximum about 3.5N megabit.
As everyone knows, if network traffic data is mainly provided by point to point service, PTP, the uplink bandwidth of user side needs can be less than downlink bandwidth so.Adopt present aggregation of bandwidth or connect cooperation technology, can not obtain higher uplink data transmission rates from adsl link.
