The 6th step: first line of a couplet gateway receives ethernet frame from network side, removes the Ethernet frame head this ethernet frame is reduced to the IP packet, and this IP packet is decomposed into ATM cell according to the IPOA packaged type, passes through the DSL circuit again to user side.
Below in conjunction with accompanying drawing, above-mentioned each step is described in further detail.
Fig. 1 is according to the DSLAM of the embodiment of the invention and the process chart between the MODEM.This Fig. 1 has described the processing in aforementioned second step, as shown in Figure 1, comprises following processing:
Step 101:DSLAM sends atm address resolution agreement request (ATM ARP Request) message, and request obtains the IP address of the MODEM of terminal equipment, simultaneously, gives this MODEM with the IP address notification of gateway.
Step 102:MODEM responds the atm address resolution agreement and replys (ATM ARP Reply) message to DSLAM, and this message is carried the IP address of this MODEM, thereby DSLAM obtains the IP address of this MODEM.
Fig. 2 is according to the DSLAM of the embodiment of the invention and the process chart between the gateway, and this Fig. 2 has described the processing in aforementioned the 3rd step.As shown in Figure 2, comprise following processing:
Step 201:DSLAM sends ARP Request message to first line of a couplet gateway, and request obtains the MAC Address of first line of a couplet gateway, simultaneously, the IP address of the MODEM of terminal equipment and the MAC Address of distributing to IPOA user is announced to this first line of a couplet gateway.
Step 202: this first line of a couplet gateway is responded ARP Reply message and is given this DSLAM, and from then on ARP Reply message is carried the MAC Address of this first line of a couplet gateway, thereby this DSLAM obtains the MAC Address of first line of a couplet gateway.
Fig. 3 is the protocol stack schematic diagram according to the DSLAM IPOA connecting system of the embodiment of the invention.Below in conjunction with protocol stack shown in Figure 3 aforementioned the 4th to the 6th step (processing of data flow between DSLAM and first line of a couplet gateway) is described in detail.
As shown in Figure 3, in the protocol stack between DSLAM and the MODEM, from the bottom to the high level, be respectively: DSL layer (that is, the physical layer of transfer of data), ATM protocol layer, ATM Adaptation Layer 5 (AAL5, ATM Adaptation Layer Type 5), IPOA protocol layer and IP layer; And in the protocol stack between DSLAM and the first line of a couplet gateway, from the bottom to the high level, be respectively: physics (PHY) layer, Ethernet (ETH) protocol layer and IP layer.
By the protocol stack between aforementioned DSLAM and the MODEM, Data Stream Processing from MODEM to DSLAM comprises: in MODEM, IP packet from the user encapsulates in the IPOA mode, be converted into ATM cell, and be physical carrier with DSL, this MODEM sends packaged ATM cell to DSLAM by the DSL circuit; The ATM cell that this DSLAM decapsulation is received obtains the IP packet.
By the protocol stack between aforementioned DSLAM and the first line of a couplet gateway, Data Stream Processing from DSLAM to first line of a couplet gateway comprises: in DSLAM, the IP packet that is obtained by the ATM cell decapsulation is coupled with specific Ethernet frame head to form ethernet frame, wherein, source MAC is a MAC Address of distributing to IPOA user, and target MAC (Media Access Control) address is the MAC Address of first line of a couplet gateway.This ethernet frame exchanges to first line of a couplet gateway by Ethernet; This first line of a couplet gateway removes the reduction of Ethernet frame head and obtains the IP packet.
Accordingly, when DSLAM when first line of a couplet gateway is received ethernet frame, remove the reduction of Ethernet frame head and obtain the IP packet, this IP packet is decomposed into according to the IPOA packaged type is encapsulated as ATM cell, again by the MODEM of DSL circuit to user side; This MODEM ATM cell of receiving of decapsulation again obtains the IP packet.
Fig. 4 is the internal module structure chart according to the DSLAM equipment of the embodiment of the invention.This DSLAM exchanges based on Ethernet, and its inside mainly is divided into three modules: segmentation and heavily distribute (SAR, Segmentand Reassign) module, two layers of exchange (L2 SWITCH) module and the first line of a couplet (UP LINK) module.
The SAR module be used for to from the ATM cell of MODEM with change mutually from the ethernet frame of first line of a couplet network, to realize multiple access packaged type; L2 SWITCH module is the exchcange core of DSLAM, is used to realize 2 layers of exchange; UP LINK module is used to realize and the docking and exchange of first line of a couplet network that the ethernet frame that the SAR module package is obtained exchanges to first line of a couplet gateway.Among Fig. 1 and Fig. 3, the processing that DSLAM did mainly thus the SAR module finish; Among Fig. 2, the processing that DSLAM did is then realized by UP LINK module.
Wherein, the SAR module is used to dispose the IP address of first line of a couplet gateway, obtain user side MODEM the IP address and export to UP LINK module, described MODEM is given in the IP address of announcement first line of a couplet gateway, to be reduced to the IP packet from user's ATM cell, obtain ethernet frame for the IP packet adds the encapsulation of Ethernet frame head; Being used to remove the Ethernet frame head from the ethernet frame of first line of a couplet network, ethernet frame is reduced to the IP packet, is ATM cell with the IP packet encapsulation, and transmits ATM cell to MODEM; UP LINK module is used to obtain the MAC Address of first line of a couplet gateway and will distributes to user's MAC Address and the IP address notification of MODEM is given first line of a couplet gateway, and the ethernet frame that the SAR module package is obtained by Ethernet exchanges to first line of a couplet network; Reception is from first line of a couplet network ethernet frame and be sent to the SAR module.
The SAR module can comprise a submodule, and it is used for giving MODEM by ARP message with the IP address notification of first line of a couplet gateway.UP LINK module also can comprise a submodule, and its IP address notification that is used for will distributing to by ARP message user's MAC Address and MODEM is given first line of a couplet gateway.
Describe as can be known by above embodiment, adopt the embodiment of the invention to adopt the IPOA packaged type and DSLAM network side during, realize that the user inserts the user by the Ethernet first line of a couplet.In embodiments of the present invention, the source MAC of Ethernet frame head and target MAC (Media Access Control) address are transparent for user side, wherein, source MAC can be defined voluntarily by the DSLAM system, to distinguish different IPOA user in addition, purpose MAC is the MAC Address of first line of a couplet gateway, and this target MAC (Media Access Control) address can obtain by configuration or ARP agreement.Simultaneously, DSLAM announces the IP address of MODEM to first line of a couplet gateway with the source MAC of distributing to IPOA user by ARP message, it also obtains the IPOA user's IP address by ATM ARP agreement, simultaneously the IP address notification of first line of a couplet gateway is given the MODEM of user side, thereby can be specified specific first line of a couplet gateway for each IPOA user.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
