Example 1
Referring to fig. 1, the present embodiment provides a trans-regional forwarding method, which includes the following steps:
step S1: a forwarding gateway is respectively arranged for each region;
step S2: initializing each node of each region, and initializing each region;
step S3: the message to be sent is sent through a node of a sender, and the message to be sent is endowed with receiver information, wherein the receiver information comprises node information and region information of a receiver;
step S4: the forwarding gateway of the sender in the area where the node of the sender is located receives the message to be sent;
step S5: analyzing the information of the receiver through a forwarding gateway of the sender to obtain a target node, wherein the target node comprises at least one node of the receiver;
step S6: and the forwarding gateway of the sender judges that the forwarding type of the current forwarding is off-site forwarding or local forwarding according to the information of the receiver, and when the off-site forwarding is performed, the message to be sent is forwarded to the target node through the forwarding gateway of the receiver by adopting an off-site forwarding strategy.
The core ideas and methods of this embodiment are as follows:
a forwarding gateway is a network device or software whose main function is to forward data packets from one network to another, and is typically used to connect to a different Local Area Network (LAN) or to connect a LAN to the internet. The extension is that a forwarding gateway is arranged for each large area, which can realize more efficient and rapid data transmission and communication between networks of different areas.
And forwarding gateways are respectively arranged in all areas and play a role of a transfer station, and are responsible for receiving the message to be sent from the node in the area where the forwarding gateway is located, then transferring the message to the forwarding gateway in the area where the receiver is located, and further sending the message to the target node by the forwarding gateway in the area where the receiver is located. The method is characterized in that when the forwarding gateway of the sender judges that the forwarding type of the current forwarding is remote forwarding or local forwarding according to the information of the receiver, the forwarding gateway can simply make the judgment by depending on the regional information.
When the cross-regional communication is performed through the network, the to-be-sent message in one region is usually sent to a plurality of target nodes in another region, and multiple cross-regional forwarding can greatly reduce the propagation rate and efficiency of the message, so that transmission errors are caused, and inaccurate results and the like are caused due to low message synchronism of each node in the scenes such as distributed simulation and the like. Here, the essential trans-regional forwarding only uses the forwarding gateway of the sender to the forwarding gateway of the receiver, that is, referring to fig. 2, when the node 1 of the sender in the area a forwards the message to the receiver in the area B, it is only necessary to perform trans-regional forwarding once without any destination nodes in the area B; when the traditional method is adopted to perform trans-regional forwarding, when a sender in the area A forwards a message to a receiver in the area B, assuming that 100 target nodes exist in the area B, namely nodes 1 to 100, the trans-regional forwarding needs to be performed 100 times. The comparison can show that the number of the trans-regional forwarding messages is greatly reduced, namely trans-regional forwarding is converted into a sending scheme which mainly depends on local transmission, so that the message transmission efficiency of the trans-regional messages is improved, and the delay, the error and the like of trans-regional transmission are reduced.
After the optimization of the embodiment is carried out, the scheme for transmitting the cross-regional information can be better applied to a distributed simulation system with higher real-time requirements, such as a digital simulation battlefield and the like in which cross-regional multiple users participate together, a high-quality, accurate and rapid cross-regional forwarding scheme can be provided for the services, a foundation is provided for better simulation, and a simulation result of the distributed simulation system with higher accuracy is ensured.
It is also specifically noted that the steps S1-S2 of the previous setting are all preamble preparation works, and all subsequent message sending works can be guaranteed after one completion, and repeated setting and initialization are not needed.
Example 2

The domain number and the node number are used as receiver information and are added in the message to be sent, the target node can be accurately positioned by means of the domain number and the node number while the data amount to be processed and identified is small, the sending processing is convenient, the efficiency and the accuracy of the data identification processing process are improved, and further guarantee is provided for a strategy of cross-region efficient forwarding.
The node number and the domain number can be realized by simple numbers and/or letters and/or symbols, in particular, for accurate positioning, the domain numbers of different areas must be different, repetition cannot occur, the node numbers in the same area must be different, and for the node numbers of different areas, as for the node numbers of different areas, the actual receiver information comprises the node number of the receiver node and the domain number of the area where the receiver node is located, when the node numbers are forwarded, the domain numbers are preferentially read and forwarded, so that the node numbers of different areas generally cannot have conflict problems, but according to management requirements, different node numbers can be given to all nodes.
As a preferred solution, the method for forwarding the message to be sent to the target node through the forwarding gateway of the receiver by adopting a remote forwarding policy includes:
the forwarding gateway of the sender obtains the area information of the receiver through the information of the receiver;
the forwarding gateway of the sender integrates the message to be sent and sends the message to the forwarding gateway of the receiver; the integration is mainly to integrate the messages to be sent to the forwarding gateway of the same receiver, which is the same with the content, so as to reduce the frequency of remote sending;
the forwarding gateway of the receiver acquires node information of the receiver through the receiver information, and acquires the target node;
and the forwarding gateway of the receiver sends the message to be sent to the target node of the receiver.
If the above method combines the domain number and the node number, the actual operation method is that:
the forwarding gateway of the sender obtains the area information of the receiver, namely the domain number, through the receiver information;
after knowing the domain number, the forwarding gateway of the sender can know which area of the forwarding gateway the message to be sent should be sent to, so that the forwarding gateway of the sender can be precisely positioned by the domain number to send the message to the forwarding gateway of the receiver;
the forwarding gateway of the receiver acquires the node information of the receiver through the node number in the receiver information, and directly and accurately acquires the target node;
and finally, the forwarding gateway of the receiver sends the message to be sent to the target node of the receiver.
Likewise, if the above method combines the domain number and the node number, the actual operation method is that:
the forwarding gateway of the sender obtains the node number of the receiver through the receiver information, and directly locates and obtains the target node;
and the forwarding gateway of the sender sends the message to be sent to the target node of the receiver.
