The present invention relates to method and access device that a kind of message is handled, particularly a kind of support is by BOOT strapping Protocol (Bootstrap Protocol, hereinafter to be referred as: BOOTP) or DHCP (Dynamic Host Configuration Protocol, hereinafter to be referred as: DHCP) processing method and the access device of request IP address message, to support by asynchronous transfer mode (AsynchronousTransfer Mode, hereinafter to be referred as: ATM) carrying IP (IP over ATM, hereinafter to be referred as: IPoA) to passing through Ethernet bearing IP (IP over Ethernet, hereinafter to be referred as: the IPoE) method and apparatus that obtains of the IP address of two kinds of protocol interconnections belongs to communication technical field.
Background technology
At present, increasing telecommunications enterprise with DSL (Digital Subscriber Loop, hereinafter to be referred as: aggregation networks DSL) moves to Ethernet from atm network.Under this background, DSL forum standard tissue (DSL FORUNM) has been formulated code name and has been: the technical specification of " TR-101 "; Defined the architecture model that a kind of DSL based on Ethernet converges net therein, and special IP Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer at access node, hereinafter to be referred as: DSLAM) propose the requirement of protocol interconnection, required IP DSLAM can finish intercommunication between IPoA and two kinds of agreements of IPoE.
The IPOA agreement is to transmit a kind of technical specification of IP packet between ATM and the Ethernet.It has stipulated to utilize atm network to connect between the ATM terminal, particularly set up the crossover virtual connections (SwitchedVirtual Circuit, hereinafter to be referred as: SVC) carry out the standard of IP data communications.The IPoE agreement then is that user end computer is used for the IP message is packaged into a kind of agreement that Ether frame is delivered to the user side switch.Realize the intercommunication between IPoA and two kinds of agreements of IPoE, then can support IPoA user to be linked among the aggregation networks based on Ethernet.Referring to Fig. 1, Figure 1A, Figure 1B, in the prior art, realize the exchanges data of the routing device 3 of IPoA user 1 and Ethernet-Aggregation network, should carry out protocol conversion to IPoA user's IP message by IP DSLAM2, the IP message that will have the ATM heading is converted to the IP message with Ethernet header; Figure 1A and Figure 1B are respectively IPoA message and IPoE message structure schematic diagram.Aforesaid conversion is finished by IP DSLAM2 as shown in Figure 2; Therein, the process of the protocol interconnection IPoA IWF protocol stack of IPoA and IPOE and message encapsulation conversion is as follows:
1, IP DSLAM2 is by address resolution protocol (Address Resolution Protocol, ARP) medium access control (the Media Access Control of study (acquisition) purpose IP correspondence, hereinafter to be referred as MAC) address also is the interface mac address that three-layer network closes;
2, IP DSLAM2 is by reverse ATM ARP (inverse ATM ARP, hereinafter to be referred as: agreement study (acquisition) IPoA user's 1 IP address inATM ARP), if IPoA user 1 does not support the inATMARP agreement, must be on IP DSLAM2 the static configuration source IP address.After having only IPoA user 1 IP address to determine, IPDSLAM2 just for its distribution MAC Address, finishes the IWF function.
3, on the basis of aforementioned two steps, IP DSLAM2 is converted to the IPoA data message packing forms that meets the IPoE agreement, wherein, distributed by IP DSLAM according to the source MAC in the data message Ethernet header of IPOE protocol encapsulation, purpose MAC then is the MAC Address that obtains in the abovementioned steps 1;
4, IP DSLAM replys the three-layer network equipment that closes IPoA user is asked
