Description
Technical field
The present invention relates to network access equipment, relate in particular to the function of the circuit access card that is used for the extended network access device and the apparatus and method of performance.
Background technology
In recent years, broadband access market has obtained development fast, multiple broadband access technology has appearred, for example digital subscriber line (xDSL), gigabit passive optical network (GPON), based on EPON (EPON) of Ethernet etc., in the network access equipment of these technology of employing, all relate to such as relatively more complicated signal processing such as the conversion between the different agreement, the application of adaptation different business.
For example, the digital subscriber line access multiplex of IP network (IP DSLAM) is a kind of local side network access equipment of xDSL, it is mainly used in Layer 2 data forwarding, three layer data forwardings, IPTV and relevant user security and authentication protocol (AAA/Radius, DHCP, PPPOE, IPOE, 802.1x, IGMP, QoS ...) etc.
Fig. 1 illustrates a topology of networks figure who comprises IP DSLAM, and wherein, the interface of the network terminal of IPDSLAM is connected with the webserver by IP network, and its user side interface then is connected in user terminal by PSTN (PSTN).
The basic functional principle of IP DSLAM is as follows: the signal of sending by PSTN (PSTN) by user terminal of uploading through IP DSLAM demodulation after, revert to atm cell format, convert thereof into the corresponding Ethernet data bag then, at last this Ethernet data bag is transferred to the webserver by IP network; The Ethernet data bag of sending by the webserver, be transferred to IP DSLAM through IP network, on IP DSLAM, convert the Ethernet data bag to ATM cell, and after the processing and modulation by the xDSL port on the IP DSLAM, the signal of IP DSLAM output passes through PSTN (PSTN) again and outputs to user terminal.
EPON (EPON) based on Ethernet is a kind of optical access network that a little arrives the multidrop topology structure that has, and adopts Passive Optical Components to connect local side and remote equipment, realizes the transmission of Ethernet service, and can realize the access of integrated services such as voice, video.Comprise optical line terminal (OLT) and optical network unit (ONU) in the EPON system, wherein OLT is positioned at local side, finish with broadcast mode and send Ethernet data, the control of control ONU power, be that ONU distributes functions such as bandwidth to ONU, ONU is positioned at user side, and its function comprises: the broadcast data that selective reception OLT sends; Range finding and power control command that response OLT sends, and do corresponding the adjustment; Ethernet data to the user carries out buffer memory, and sends to up direction in the send window that OLT distributes.
Existing network access equipment (for example IP DSLAM, EPON etc.), particularly low-end product wherein is often because the restriction of self hardware capabilities, can't satisfy the demand that the user increases day by day, for example, the ability of the circuit access card among IP DSLAM or the EPON is subjected to the restriction of its internal resource and disposal ability, make that existing product becomes and more and more can not adapt to the demand that the user increases day by day owing to hardware constraints, make the product of some low sides have to quit listing in advance.
Now, there has been certain methods to be suggested the improvement network access equipment, to adapt to the demand that the user increases day by day, for example:
