After family terminal and throwing screen equipment are connected into consolidated network, if user terminal and throwing screen equipment exist under same physical subnets, such as
Room 1 can find target after then user terminal issues IP address bind request in same floor under same physical subnets
Screen equipment is thrown, and under present physical subnet, bind request is directly transferred to throw screen equipment processing, at this time in network protocol
Only need a data forwarding；If user terminal and throwing screen equipment not under same physical subnets, such as user terminal is in room 1,
Target throws screen equipment in room 2, then after user terminal issues IP address bind request, according to principle is preferentially searched for, can exist first
Screen equipment is thrown in search in physical subnets where user terminal, if not finding, by physical subnets gateway, is sent out to router
Searching request out need to scan in the whole network at this time by network layer, then transfer to target to throw screen equipment bind request again
It is handled, is needed in network protocol at this time by multiple data forwarding；If user terminal or throwing screen equipment and net in the process
Network disconnects, or occurs other and can not carry out the failure of normal data communication, then to user terminal feedback request time-out；
For example, there is tetra- equipment of ABCD to belong to 10.0.0.0 physical subnets, gateway is directed toward the port 10.0.0.1 of router；
There are tetra- equipment of EFGH to belong to 10.0.1.0 physical subnets, gateway is directed toward the port 10.0.1.1 of router；Physical subnets pass through
IP address divides；Network topology is as shown in Figure 3；
Assuming that equipment A is user terminal, equipment C, equipment E are to throw screen equipment, are tied up if equipment A sends IP address to equipment C
Fixed request, or request are connect with equipment C, then in L2 data link layer, forward a 10.0.0.0 physical subnets by interchanger 1
Interior data frame；If equipment A sends IP address bind request to equipment E, or request is connect with equipment E, then needs L3 network
The path planning function of layer, carries out multiple data forwarding, i.e. the data packet for being sent to equipment E is sent to by equipment A
The data packet is sent to router 1 by gateway by 10.0.0.0 physical subnets gateway, after router 1 receives data packet,
It locally can not find the IP address of equipment E, then router 1 sends the broadcast for searching equipment E, road in current network (hotel's the whole network)
After receiving broadcast by device 2, equipment E is locally being found, and feed back to router 1, that is, passing through " equipment A-gateway router-road
The process of subnet where finding equipment E by routing-between device ", equipment A could be communicated with equipment E, due to equipment A and equipment
It experienced multiple physical subnets between E, it is therefore desirable to which multiple L2 layer forwarding is just able to achieve the arrival of data packet, L3 during being somebody's turn to do
The MAC Address of layer IP packet outsourcing frame can be converted constantly；
Assuming that equipment A uses 88 ports, equipment B uses 99 ports, then data frame and IP packet in the above process
Address experience process it is as shown in Figure 4；
Any router can not all spy upon whole network, therefore every router is all found simply by Routing Algorithm
The optimal path of next-hop, these optimal paths, which connect, just forms a complete path；That is the forwarding road of router
What diameter was not chosen by a router, the next hop address sequence that multiple router common choices come out under the whole network
Column；
If equipment A or equipment C, equipment E and network disconnect in the process, or occur other and can not carry out normal number
According to the failure of communication, then to equipment A feedback request time-out.
During the stream compression of the IPV4 network protocol lower network data forwarding, data communication process as shown in figure 5,
Include:
S51: the request data package of current network acquisition user terminal；
S52: throwing screen equipment IP by user terminal IP, target, judges that whether target throws screen equipment in present physical subnet
In；If so, otherwise entering S54 into S53；
S53: screen equipment MAC Address is thrown by APR agreement request target；
The MAC Address is inserted into ethernet frame；
Complete L2 data link layer communication；
S54: present physical subnet gateway MAC Address is searched by APR agreement；
