Service type) field, high 3 of the TOS field are therefore priority field can be set using high 3 of the TOS field
The priority (the corresponding numerical value of 3 binary systems is bigger, and the priority of network layer message is higher) of network layer message, in addition, TOS
The lowest order of field is necessarily arranged to 0, remaining 4 respectively represent from a high position to low level: minimal time delay, maximum throughput, minimum
Expense and highest reliability.Therefore, terminal device can be set as 110 0100 with the TOS field of network layer message to be sent
The numerical value such as 0 (0Xc8) or 111 1,000 0 (0xf0) handle the speed of the network layer message to improve trunking, to make
The trunking priority processing network layer message is obtained, to solve since trunking Message processing burden is larger, and leads to end
End equipment can not get the technical issues of server response for a long time.In addition, the prior art has many methods TOS word is arranged
Section, for example, " iptables-t mangle-A OUTPUT-p udp-- can be instructed in the following firewall of terminal equipment configuration
Dport 53-j TOS--set-tos 0xc8 " sets the TOS field for the network layer message that destination port number is 53 to
0xc8。

Transport layer message etc.) priority be set as the technical solution of higher priority, have stronger server-compatible, it is specific former
Cause are as follows: be non-default higher level message when receiving priority in the configurator of many servers under normal conditions
When, the server can execute some orders that we are not intended to (such as not to send the higher level message terminal device into
Row response), therefore, in the technical solution provided by the embodiment of the present application one, the higher level message transmitted by the terminal device
Default priority when not being highest priority, due to the terminal device not by the priority of the higher level message by force from
Default priority is changed to higher priority, so, the server for receiving the higher level message will not be because of the higher level message
Priority be not default priority and execute some orders that we are not intended to.So the embodiment of the present application one is provided
