The heading length of the message of type is 18 bytes, and the heading length of the message of type-A is long more than the heading of the message of B types
Degree, according to the heading length of the message of type-A, it is determined that reserved storage size is not less than 20 bytes.
Specifically, after message to be sent is received, according to the length of message to be sent, and default reserved storage
The size sum in space, determines the size of the memory space that message to be sent need to take, and the packet storage is big to correspondence
Little memory space, in storage, the afterbody of the message is alignd with the afterbody of the memory space, and reserved storage space exists
Before the memory space that the message takes and adjacent position, during to send, in the reserved storage space message is added
Head.For example：The message length to be sent for receiving is 20000 bytes, and the size of default reserved storage space is 20 bytes,
The size for then determining the memory space that message to be sent need to take is 20020 bytes, by the report to be sent for receiving
To in the memory space that size is 20020 bytes, in storage, length is the message trailer to be sent of 20000 bytes for text storage
Portion aligns with the afterbody of the memory space of 20020 byte, what the memory space of 20 reserved bytes took in the message
Before memory space and adjacent position.
S102：Whether the length of the message is judged more than maximum message segment segment length MSS, if it is, the message is drawn
It is divided into many sub- messages, per the length of individual sub- message the MSS is not more than.
Because in existing network communication during message transmissions, the length of whole message can not be more than MTU, and in concrete transmission
Each message can encapsulated message head, therefore when message transmissions are carried out, can hold after the length that heading is removed in each message
Length MSS of the message of load is certain, if so the length of message to be sent is needed report to be sent more than MSS
Text is divided into the sub- message that multiple length are not more than MSS.
Specifically, whether the length of message to be sent is judged more than MSS, if it does, explanation is needed the message
Many sub- messages are divided into, the length of each message is not more than MSS values.Can be with identical per the length of individual sub- message when dividing
Can be with difference, preferably, the length per individual sub- message that can make division is equal to MSS, the length of last sub- message can
With less than MSS.
S103：The plurality of sub- message is divided at least two message groups, it is sub that each message group package includes at least two
Message, and the sub- message of any two that each message group package contains is non-conterminous.
During sending in sub- message, after being often sent completely a sub- message, it is required for returning a sub- message
The response message being sent completely, and electronic equipment often receives a response message and is required for being processed, so as to reduce it
The efficiency of message transmission is carried out, and wastes substantial amounts of process resource.And sub- message is drawn in message group, with message group as list
Position sends sub- message, after all sub- message included in message group is all sent completely, just returns a message group neutron message

Sub- message, per the sequence number of individual sub- message 1,2 ... 15,16 are followed successively by, and sub- message can be divided into into two message groups, wherein one
In individual message group comprising serial number 1,3,5,7,9,11,13,15 sub- message, in another message group comprising serial number 2,4,6,
8th, 10,12,14,16 sub- message, it is also possible to which sub- message is divided into into three message groups, includes sequence number in one of message group
For 1,3,6,8,11,13,15 sub- message, the sub- message of serial number 4,7,10,12,16 is included in another message group, further
Sub- message comprising serial number 2,5,9,14 in individual message group, as long as the sub- message of any two included in each message group not phase
It is adjacent.
Preferably, user can according to demand set the maximum quantity comprising sub- message in each message group, for example：User
Above-mentioned sub- message can be then divided into four message groups by the sub- message maximum quantity included in each the message group for setting as 4,
Sub- message of first message group package containing serial number 1,3,5,7, sub- message of second message group package containing serial number 2,4,6,8, the 3rd
Sub- message of the message group package containing serial number 9,11,13,15, sub- message of the 4th message group package containing serial number 10,12,14,16, only
The quantity for meeting the sub- message included in each message group is not more than the maximum message segment quantity and each message group of user's setting
In the sub- message of any two that includes it is non-conterminous.
Sub- message is divided into into different message groups, the son report included in message group is sent together in units of message group
Text, after the sub- message included in message group all completes to send, returns the response message that a message group is sent completely, if
It is to be transmitted in units of per individual sub- message, after being often sent completely a sub- message, it is necessary to return a sub- message and send
The response message for completing, causes the waste of process resource, affects the transmitting efficiency of message.
S104：In for each message group per individual sub- message, before caching corresponding first memory space of the sub- message
And the data of the second memory space storage of adjacent preseting length, the sub- message pair is added in second memory space
