Described 2nd PWI logical drive module, for reduce described message receiver module receive Ether frame message be wide area network link message, and parse the pseudo-Wide Area Network interface of this message of local reception, the wide area network link message restored is submitted to local corresponding pseudo-Wide Area Network interface process.
Illustrate the specific implementation process of wide area network link analog detection method below:
One, first, enable the PWI function of local terminal network equipment A and peer network device B, simulation creates pseudo-Wide Area Network interface, and the pseudo-Wide Area Network interface created and its physical interface is bound;
Simulation creates pseudo-Wide Area Network interface and the mode of carrying out binding with its physical interface is as follows:
1) create PWI group by order, any number of pseudo-Wide Area Network interface can be created under a PWI group, but these interfaces all own the attribute of PWI group together;
2) type (as: serial, pos, sync, async, atm) of specifying this PWI to form to build pseudo-Wide Area Network interface, here for serial type;
3) PWI group and Ethernet interface ETH0 are bound;
4) MAC Address of opposite end Ethernet interface ETH0 is specified;
5) opposite end PWI group number is specified;
6) in PWI group, create a pseudo-Wide Area Network interface, wherein the interface index of this pseudo-Wide Area Network interface can consist of PWI group number and No. unit of specifying when creating interface, as: serial0/0.
The pseudo-Wide Area Network interface created by above-mentioned steps for link layer and above level with physical interface without any difference, various link layer protocol can be encapsulated (as PPP on pseudo-Wide Area Network interface, HDLC, FR etc.), but pseudo-Wide Area Network interface is without real physical drives, therefore be that each pseudo-Wide Area Network interface realizes logical drive by PWI logical drive module in the present invention, the major function of this logical drive has been the transparent transmission of the message of wide area network link encapsulation format on ether circuit.
Two, the transmission of message on local terminal network equipment A:
1) message of original wide area network link encapsulation is sent by pseudo-Wide Area Network interface serial0/0, and final message can process to a PWI logical drive module.
2) local terminal PWI logical drive is the privately owned head of this message encapsulation PWI, carries group and No. unit.The encapsulation format of privately owned head as shown in Figure 4, wherein:
Type:1 byte (1Byte), represents type of message, is PWI protocol massages or PWI data message for distinguishing.
IfType:1 byte (1Byte), interface type (attribute of PWI group configuration, type comprises serial, pos, sync, async, atm), the dissimilar interface negotiation in two ends is unsuccessful.
Group:2 byte (2Byte), the group number of opposite end PWI, represents that opposite end processes the PWI group number of this message.
Unit:2 byte (2Byte), interface index, two ends interface index is identical.
Len:2 byte (2Byte), the total length of original wide area network link message.
3) according to the MAC Address of the interconnected ether interface in opposite end of configuration, encapsulation Ethernet link head, arranging Ether protocoll type is 0x9800 (can be other and the conflict free value of existing protocol type), and the message format after encapsulation as shown in Figure 5.
4) the physics ether interface ETH0 of the Ether frame form message after encapsulation from configuration binding is sent to ether circuit and gets on by message sending module.
Three, the reception of message on peer network device B:
1) message receiver module is according to the protocol type of message (0x9800 can be other and the conflict free value of existing protocol type), and identifying is the message belonging to PWI encapsulation, will transfer to PWI logical drive module to receive and process.
2) the 2nd PWI logical drive module parses the group and No. unit carried in PWI header information, thus determines that this message needs to send to the link processing of which pseudo-Wide Area Network interface.
3) the ether head of message removes by the 2nd PWI logical drive module PWI logical drive module, is reduced into the message of original wide area network link encapsulation.
4) original wide area network message is handed over corresponding pseudo-Wide Area Network interface link processing.
The logical drive part of the pseudo-Wide Area Network interface in the present invention simultaneously, use the mechanism of token bucket to achieve Limit Rate, simulation is similar to the bandwidth congestion situation of physical interface.
It should be noted that, the message of equipment two ends wide area network link encapsulation is in the present invention packaged into Ethernet message, transparent transmission on ether circuit.In fact, the interface being not restricted to EtherType of PWI group binding, can bind the physical interface of any type in theory, and the frame format of just final encapsulation there are differences.Here consider in practical application the most frequently used it is most convenient that the interface of EtherType, therefore the present invention only implement on Ethernet interface.In addition, having carried out final message encapsulation by the information (MAC Address and PWI group number) of manual configuration opposite end in the present invention, in fact also can consult the information at mutual two ends by realizing PWI proprietary protocol, without the need to manual configuration.
