1, behind the packet that this network interface card receives from physical circuit by its hardware, therefrom read the identification information that has protocol type, IP address, again by the discriminant function in the network interface card driver module, with on this information and this driver module in advance the relevant information of a plurality of agreements of binding judge comparison, do not reject this packet if information matches, continue if information is complementary to handle.For example, this moment this network interface card to read its protocol type from the packet that receives be the IP agreement, the IP address is 1.1.1.1; And bind two agreements on the driver module of this network interface card in advance, as mentioned above, its relevant information is: PPPoE protocol type, 1.1.1.0 (IP address) and IP protocol type, 1.1.1.1 (IP address).(protocol type: the IP agreement, the IP address: 1.1.1.1) judge relatively with this relevant information, just meet second quasi-protocol, then this packet turns to IP bag driver module to handle to the identification information that will read from packet by above-mentioned discriminant function.
This process realizes that with software used pseudo-code is as follows:
function?ni_receive
{
If (bag of receiving is the PPPoE bag)
Turn to PPPoE bag driver module
Else
Turn to IP bag driver module
}
As above-mentioned flow process,, more then it is matched this PPPoE bag driver module by above-mentioned judgement if the packet that receives is the PPPoE bag; If more all do not meet through judging, then this packet return.
2, this driver module is handled this packet accordingly according to the protocol rule of its coupling, and this packet is through unpacking and other local data of handling back formation, by the port output of this Network Interface Unit.
After the driver module of this PPPoE bag or IP bag is handled this packet accordingly according to PPPoE agreement or IP agreement respectively, handle accordingly via network layer, its formed data in processing back are exported to the upper strata by this driver module and are handled again.
function?pppoe_receive
{
With the format conversion of PPPoE message is IP bag datagram format
Message after the conversion is sent to network layer to be handled
}
Forwarding step, it is to send after data are processed into packet according to specific protocol, is specially:
A, according to the identification information that includes protocol type, IP address in the data to be sent, successively the identification information of this information and each agreement is judged comparison, refuse to send these data if information does not match, continues processing if information is complementary.For example, identification information is PPPoE agreement (type), 1.1.1.0 (IP address) in the data that this moment, this network interface card need send, discriminant function in this network interface card driver module is judged this information and the relevant information of having stored (PPPoE protocol type, 1.1.1.0 (IP address) and IP protocol type, 1.1.1.1 (IP address)) relatively mutually, just meet first kind agreement, then these data turn to PPPoE bag driver module to handle.
This process realizes that with software used pseudo-code is as follows:
function?ni_send
{
If (need send to the PPPoE server)
Turn to PPPoE bag driver module
Else
Turn to IP bag driver module
}
B, this driver module are handled these data accordingly according to the protocol rule of its coupling, and these data are handled the packet that the back forms through packing and other this locality, by the port output of this Network Interface Unit.
After the driver module of this PPPoE bag or IP protocol package is handled these data accordingly according to PPPoE agreement or IP agreement, via data link layer, network layer are handled accordingly successively again, and it handles the port output of the formed packet in back by this network interface card.
function?pppoe_send
{
The IP message format is converted to the PPPoE message format
Message after the conversion is sent to physical layer
}
