Detailed Description
To make the structure and advantages of the present invention clearer, the structure of the present invention will be further described with reference to the accompanying drawings.
Example one
The invention provides a processing method for eliminating service looping, as shown in fig. 1, the processing method includes:
11. enabling the sample terminal to obtain a first ID value of the MMS message, adding a forwarding field in the MMS message to obtain a first MMS message, and sending the first MMS message to the switch;
12. the switch modifies the forwarding field in the first MMS message to obtain a second MMS message, and forwards the second MMS message;
13. and enabling the terminal receiving the second MMS message to extract a forwarding field in the second MMS message, inquiring a third register table item corresponding to the forwarding field, acquiring target outlet configuration content corresponding to the second MMS message, extracting a second ID value in the second MMS message, and judging the forwarding behavior of the second MMS message according to the matching result of the first ID value and the second ID value and the target outlet configuration content.
In the implementation, firstly, a first ID value and a forwarding field of an MMS message are obtained in a sample terminal, the first ID value and the forwarding field are stored in the MMS message, a first MMS message is further obtained, the first MMS message is sent to an exchanger, secondly, after the exchanger receives the first MMS message, the forwarding field in the first MMS message is modified, a second MMS message is obtained, the second MMS message is forwarded back to the terminal from the exchanger, finally, the terminal receiving the second MMS message extracts the forwarding field in the second MMS message, a third register table entry corresponding to the forwarding field is inquired, a target outlet configuration content corresponding to the second MMS message is obtained, the second MMS message obtains a second ID value, matching is carried out according to the first ID value and the second ID value, if a matching result is obtained, the first ID value is consistent with the second ID value, namely, the target outlet configuration is set, the second MMS message is not forwarded out of the port, i.e., the port from which the MMS message was originally sent does not receive the originally sent MMS message.
Based on the processing method, the first ID value of the MMS message is obtained through the sample terminal, the second ID value of the second MMS message is obtained through the terminal receiving the second MMS message, the first ID value and the second ID value are matched, the matching result is obtained, the forwarding behavior of the second MMS message is judged according to the obtained matching result, and when the matching result shows that the first ID value and the second ID value are consistent, the second MMS message is not forwarded from a port under the terminal which originally sends the MMS message, but can be forwarded from a port under the other terminal. The same message can not be sent out again from the same port of the same terminal, so that the problem of cyclic transmission of the message between the terminal and the switch caused by the same message is prevented, the communication delay is reduced, and the normal transmission of the message in the terminal and the switch is ensured.
Optionally, the making the sample terminal obtain the first ID value of the MMS message includes:
acquiring a source port number of an MMS message, searching a first register table item according to the source port number of the MMS message, acquiring a first ID value, and adding the first ID value and the source port number to the tail part of the message;
the value range of the first ID value is 0-1023.
In implementation, in order to obtain the first ID value of the MMS message, the source port number of the MMS message needs to be obtained, then the content of the first register entry is queried according to the obtained source port number, and the first ID value representing the name of the sending port of the MMS message, which corresponds to the MMS message, is determined according to the content in the first register entry.
Since the obtained first ID value is used in the subsequent determination step, the first ID value needs to be sent simultaneously along with the MMS message, and the sent MMS message also includes the queried source port number, so that before the sample terminal sends the MMS message, the operation of adding the first ID value and the source port number to the tail of the MMS message is performed.
And for each sample terminal device, the results of the first register table entries are different, wherein the value range of the first ID value is 0-1023.
Optionally, adding a forwarding field in the MMS message to obtain a first MMS message, and sending the first MMS message to the switch includes:
and acquiring a source port number of the MMS message, searching the table entry of the second register according to the source port number of the MMS message, adding a forwarding field after the MAC source address in the MMS message based on the searched result to obtain a first MMS message, and sending the first MMS message to the switch.
In implementation, because the IP address is not enough, the IP capacity of a class subnet is limited, and the number of available IPs is expanded by adopting a forwarding field mode. In order to obtain the forwarding field of the MMS message, the source port number of the MMS message needs to be obtained, then the content of the second register table entry is inquired according to the obtained source port number, and the forwarding field corresponding to the MMS message is determined according to the content in the second register table entry.
Because the forwarding field needs to be used for subsequent determination steps, the obtained forwarding field needs to be sent simultaneously along with the MMS message, the forwarding field is added with the MAC source address in the MMS message to obtain a first MMS message, and then the first MMS message is sent to the switch.
Optionally, the instructing the switch to modify the forwarding field in the first MMS message to obtain a second MMS message includes:
and the switch modifies the content of the forwarding field added from the sample terminal to the switch in the first MMS message to obtain a second MMS message.
In implementation, in order to avoid the need of mobile physical connection, the IP address of the forwarding field is reconfigured after the content of the forwarding field is modified, so that the port of the switch receiving the first MMS message is not in the same network segment as the port of the switch sending the second MMS message.
Firstly, the first MMS message can be transmitted back to the sample terminal from the switch, after the switch receives the first MMS message, secondly, the content of the transmitting field added from the sample terminal to the switch in the first MMS message is modified, and finally, the second MMS message is obtained.
Optionally, the forwarding field in the second MMS message corresponds to the number of destination outlets.
In practice, the number of destination outlets is different, depending on the forwarding field in the second MMS message, and may be one or several, or even all ports will receive the second MMS message. As shown in fig. 2, N terminals are connected to each port of the switch, and a port a, a port B, a port C, and a port D are provided below each terminal.
As can be seen from the above, first, the sample terminal is enabled to obtain the first ID value and the source port number of the MMS message from any port, and add them together at the tail of the MMS message, the sample terminal is enabled to obtain the forwarding field from the same port, and add it after the MAC source address of the MMS message, so as to obtain the first MMS message, forward the first MMS message to the switch, modify the forwarding field through the switch, so as to obtain the second MMS message, and the terminal receiving the second MMS message receives the second MMS message forwarded from the switch, at this time, the port a, the port B, the port C, and the port D are used as the destination exit of the second MMS message, and according to the difference of the forwarding fields in the second MMS message, any one of the port a, the port B, the port C, and the port D can forward the second MMS message, or any two of the port a, the port B, the port C, and the port D can forward the second MMS message, even four ports of the port A, the port B, the port C and the port D can transmit the second MMS message.
Here, the number of ports provided under the terminal is not limited to the number of ports in fig. 2, and more ports may be provided under the terminal, which is not described herein again.
Optionally, the extracting the second ID value in the second MMS message includes:
and acquiring a source port number of the second MMS message, searching the first register table according to the source port number of the second MMS message, and extracting a second ID value.
In an implementation, all ports of all terminals are mapped by one ID value in order not to let the port under the terminal that originally sent the MMS message receive the second MMS message.
Firstly, in order to obtain the second ID value of the MMS message, the terminal receiving the second MMS message is enabled to extract the first ID value and the source port number at the tail of the second MMS message, so as to obtain the source port number of the second MMS message.
Secondly, inquiring the content of the first register table item according to the obtained source port number, and determining a second ID value which corresponds to the second MMS message and represents the name of the terminal for receiving the second MMS message according to the content in the first register table item.
Optionally, the determining, according to the matching result of the first ID value and the second ID value and the destination egress configuration content, a forwarding behavior of the second MMS packet includes:
matching the first ID value with the second ID value to obtain a matching result;
and if the matching result shows that the first ID value is consistent with the second ID value, the internal container in the destination outlet configuration is put in the destination outlet configuration, and the second MMS message is forbidden to be forwarded from the port corresponding to the ID value.
In the implementation, a first ID value is obtained from an MMS message and a second ID value is obtained from a second MMS message, and the first ID value and the second ID value are matched to obtain a matching result;
if the matching result shows that the first ID value is consistent with the second ID value, the destination outlet configuration item is set, and the second MMS message is prohibited not to be forwarded from the port. Because the port names of all the terminals are consistent, under the condition, the second MMS message is forwarded from the same port names of other terminals, so that the same message cannot be sent out again from the same port of the same terminal, the problem of cyclic transmission of the message between the terminal and the switch caused by the retransmission is prevented, the normal transmission of the message in the terminal and the switch is ensured, and the communication delay is reduced.
And if the matching result shows that the first ID value is inconsistent with the second ID value, the second MMS message is directly forwarded from the port.
Optionally, the forwarding field is a VLAN.
In implementation, the forwarding field is a VLAN, where the VLAN is a group of logical devices and users, and these devices and users are not limited by physical location, and can be organized according to factors such as function, department, and application, and communicate with each other as if they are in the same network segment.
As shown in fig. 2, the number of ports of the switch is excessive and the ports are in a broadcast domain, so that the performance of the network is affected. Therefore, the VLAN technology is adopted to divide a large broadcast domain into a plurality of small broadcasts so as to improve the performance of the network.
Therefore, compared with the traditional local area network technology, the VLAN technology is more flexible, and meanwhile, the network security is improved.
The invention provides a processing method for eliminating service looping, which comprises the following steps: acquiring a first ID value of an MMS message, adding a forwarding field in the MMS message to obtain a first MMS message, and sending the first MMS message to a switch; modifying a forwarding field in the first MMS message to obtain a second MMS message, and forwarding the second MMS message; and extracting a second ID value in the second MMS message, and judging the forwarding behavior of the second MMS message according to the matching result of the first ID value and the second ID value. By identifying the port on the terminal and identifying the ID of the port on the terminal to be accessed when the switch sends out the message, the message is prevented from entering the same port, thereby avoiding the generation of service looping.
