Degree, takes out private data from message buffer afterbody, then forwards the packet away.
If however, there are other member devices between the recipient of private data and sender, data message is being connect
It will usually be forwarded by other member devices before debit's reception.Now, if this other member device needs the number receiving
According to message, above deliver to protocol stack upper-layer protocol carry out Business Processing (such as will the Layer 2 data that receive message continue on deliver to
Three layer protocols carry out corresponding Business Processing), due to being processed upper-layer protocol is delivered on data message, may be based on upper
The length of the message buffer to this data message for the layer protocol is adjusted, and therefore, above-mentioned private data may be due to message
The pointer of buffering area afterbody is destroyed after being adjusted.In this case, recipient according to default private data length from
The data of mistake when message buffer afterbody reads private data, may be obtained.
For example, refer to Fig. 1, be a kind of schematic diagram of the message buffer of data message shown in the application.Receive
The data message carrying private data message buffer from position A to position E.When this data message is above delivered to three layers of association
View when carrying out Business Processing, can peel off two layers of header first, and the pointer pointing to header moves to position B from position A, then further according to
The message length of record in the header of three layer protocols, the tail pointer pointing to message buffer end position is moved to position from position E
Put C.After the completion of the Business Processing of three layer protocols, this data message is forwarded to next member device.If this member device
Private data length length5 according to being pre-configured with reads forward private data from position C, will obtain the data of mistake.
For solving the above problems, the embodiment of the present application makes the message buffer afterbody of data message by series of measures
When member device between sender and recipient for the private data forwards, will not be destroyed.Below to the technology in the application
Scheme illustrates.
Referring to Fig. 2, it is the flow chart of a kind of method of transmission private data shown in the application, the execution master of this embodiment
Body is the member device of distributed apparatus；The method comprising the steps of：
Step 201：Receive the data message carrying private data that other member devices send；Described private data bag
Include the data of transmission between the member device of described distributed apparatus.
Step 202：When processing the upper-layer protocol delivering to protocol stack on described data message, record points to described data
The deflected length of the tail pointer of the message buffer of message.
Step 203：Complete described data message when upper-layer protocol is processed, based on the described deflected length of record, will be described
The position of tail pointer is recovered to initial position, and by described data message forwarding to next member device so that receiving this number
Member device according to message obtains the described private data carrying in described data message.
Above-mentioned distributed apparatus, are made up of multiple stage member device, and every member device has independent CPU, can be independent
Carry out Business Processing and message forwards, can be interknited by network between member device.
Wherein, when needing to transmit private data between member device, can be to the number of normal transmission between member device
Message buffer according to message is extended, the afterbody of the message buffer that private data is added on, using member device it
Between normal transmission data message carrying private data；When this data message needs to produce distributed apparatus, will carry
Private data abandon.In this way so that between member device when needing to transmit private data, can be not for this
Private data individually builds message, improves operating efficiency.
Furthermore it is also possible to the length of private data be configured on every member device so that any member equipment exists in advance
When receiving the data message carrying private data, can be based on pre-configured private data length, from this data message afterbody
Read private data.
Above-mentioned protocol stack, refers to the summation of each layer protocol in network, and when transmitting a message, message can be from upper-layer protocol
By encapsulated delivery to underlying protocol, after reaching recipient, upper-layer protocol is transferred to from underlying protocol by decapsulation.
Above-mentioned message buffer, refers to the memory headroom of program storage message, by pointing to the pointer of header, pointing to data
The head pointer of starting position and the tail pointer pointing to ED position, to record the position of header, and message data area
Position.Wherein, the numerical value of this pointer current location can be recorded in pointer, by by the numerical value in tail pointer, deducting sensing
Numerical value in the pointer of header can draw message buffering section length.When message transmits in protocol stack, carry out message encapsulation
(such as processed three layer protocols are delivered on two layer message, can pass through to move with the pointer pointing to header during decapsulation, can be moved
The position of the dynamic pointer pointing to header, two layers of head are peeled off).If movement will be needed to refer in the afterbody interpolation data of message
Tail pointer to message buffer.
In the present embodiment, when by carrying the upper-layer protocol process that protocol stack is delivered on the data message of private data,
The deflected length of the tail pointer of the message buffer of above-mentioned data message can be recorded；Process in upper-layer protocol and complete above-mentioned data
After message, the length of the message buffer of above-mentioned data message changes, can be according to the above-mentioned deflected length of record, will be upper
The position stating tail pointer returns to initial position.Therefore, in the present embodiment, the private data that above-mentioned data message carries is forwarding
During will not be destroyed；The recipient of above-mentioned private data can obtain correct private data from above-mentioned data message.
In the present embodiment, above-mentioned private data, can be configured based on actual business demand by user.Work as distribution
After any member equipment of formula equipment receives user configured private data, set this private data is forwarded to other members
When standby, user configured private data can be encapsulated in the afterbody of the message buffer of data message.
As shown in figure 1, when private data is encapsulated in data message afterbody by member device, message buffer will be pointed to
Tail pointer, from message buffer data trailer position D, moves to message buffer data trailer position E, due to recording in tail pointer
The numerical value of current location, so after tail pointer moves on to position E, the length of message buffering section length increases private data length
length5.
In the present embodiment, the member device of distributed apparatus, under the configuration of user, can be sent out to other member devices
Send the data message carrying private data it is also possible to receive the datagram carrying private data that other member devices send
Literary composition.When receive that other member devices send carry private data data message when, if this data message needs to send
Upper-layer protocol to protocol stack is processed, and upper-layer protocol, when decapsulating to this data message, can abandon header；Meanwhile, it is
Improve the efficiency of Message processing, correctly process some business (such as network auditing system), can remember according in the header of upper-layer protocol
The message length adjustment message data buffering area of record.Wherein, the message length of the header record of upper-layer protocol is in repeating process
All the time constant, specifically include the header of upper-layer protocol and the length of actual data division.
As shown in figure 1, message is when two-layer protocol is transferred to three layer protocols, two layers of header are dropped, message buffer
The pointer pointing to head moves on to position B from position A；Meanwhile, the message length recording in the header according to three layer protocols, will point to
The tail pointer of message buffer ED position moves on to position C from position E.Wherein, the report recording in the header of three layer protocols
Civilian length, in IPv4, is the value of total length field record in IPV4 header；In ipv 6, it is payload length in ipv6 header
Field value adds ipv6 header length.
When this data message is forwarded to next member device again, if this member device needs to read this data message
The private data of afterbody, the tail pointer due to pointing to message buffer ED position has moved, when this member device root
According to the length based on pre-configured above-mentioned private data, when this data message afterbody reads above-mentioned private data, the number of acquisition
According to being inaccurate.
In order that the member device of subsequently received above-mentioned data message can correctly obtain what above-mentioned data message carried
Above-mentioned private data, when member device receives the data message carrying private data, when this data message delivers to agreement upper
The deflected length of the tail pointer pointing to message buffer ED position when the upper-layer protocol of stack is processed, can be recorded.So that
Deflected length in later use record recovers the position of tail pointer so that private data is retained.
In a kind of embodiment illustrating, a global variable can be preset, by the sensing message buffering of record
The deflected length of the tail pointer of area ED position stores among this global variable.
As shown in figure 1, when above-mentioned data message is transferred to three layer protocols from two-layer protocol, pointing to message buffer data
The tail pointer of end position moves on to position C from position E, simultaneously as the position recording in the pointer of sensing header and tail pointer
Numerical value change, message buffering section length is changed into length3.At this point it is possible to the deflected length length4 of tail pointer is deposited
Store up in default global variable.
In the present embodiment, after the upper-layer protocol process of member device completes above-mentioned data message, can be based on above-mentioned
In global variable record above-mentioned deflected length, by point to message buffer ED position tail pointer position recover to
Initial position；
For example, as shown in figure 1, after the completion of above-mentioned data message is processed in three layer protocols, according in above-mentioned global variable
The above-mentioned deviation post length4 of record, tail pointer is moved on to position E from position C, and in tail pointer, the numerical value of record position occurs
Change, the data length length4 abandoning before this rejoins in packet buffer section length.By above measure, when follow-up
Receive above-mentioned data message member device need obtain private data when, the length based on pre-configured above-mentioned private data
Length5, from above-mentioned data message afterbody biased forwards, can obtain correct private data.
In this example, the member device of distributed apparatus can be monokaryon equipment or device for multi-core.Wherein, when
When member device is device for multi-core, the independent process data message that multiple CPU of member device generally can be parallel.If on give
All carry private data to the data message of above-mentioned multiple CPU, then each CPU need to be according to above processing mode, will be upper
State after the completion of data message processes in upper-layer protocol, the position pointing to the tail pointer of message buffer is recovered to initial bit
Put.Therefore, in this case, each CPU can correspond to a global variable, then records in respective global variable
, when the above-mentioned upper-layer protocol to protocol stack is processed, upper-layer protocol is in the report to this data message for handled data message
After the length of civilian buffering area is adjusted, the deflected length of tail pointer.
The data message processing for each CPU, above-mentioned deflected length is probably different.With a global variable record
Deflected length, each CPU due to member device can access this global variable, and global variable will record multiple skew length
Degree.In Restoration stage, the deflected length that arbitrary CPU obtains from global variable is possibly uncertain, if the skew obtaining
Length is not the deflected length of the local tail pointer in the data message processing, then tail pointer cannot be returned to original position
Put.
For example：Member device has three CPU：CPU1, CPU2, CPU3, CPU1 process the tail pointer of data message inclined
Moving length is m；The deflected length of the tail pointer of data message that CPU2 is processed is n；The tail pointer of the data message that CPU3 is processed
Deflected length be k.Three deflected lengths are stored in same global variable three CPU, then when data message is finished
Business, CPU, when the deflected length that global variable obtains, is likely to be obtained deflected length m it is also possible to obtain deflected length n or inclined
Move length k.If the deflected length that CPU1 obtains is deflected length n or k, the tail pointer of the data message that CPU1 is processed cannot
Return to original position.
For solving this problem, can individually set a global variable to each CPU, each CPU can only access certainly
The corresponding global variable of body.In this case, the skew of the tail pointer of data message that itself can be processed by arbitrary CPU is long
Degree storage, in corresponding global variable, in the stage recovering tail pointer position, can only obtain only from corresponding global variable
One deflected length, it is to avoid cause the tail pointer of data message cannot return to because obtaining the deflected length of mistake original
The situation of position.
For example：For three CPU of member device, set a global variable respectively；CPU1 corresponds to global variable X,
CPU2 corresponds to global variable Y, and CPU3 corresponds to global variable Z.The deflected length of the tail pointer of data message that CPU1 is processed is m,
Deflected length m is stored in global variable X；The deflected length of the tail pointer of data message that CPU2 is processed is n, by skew length
Degree n stores in global variable Y；The deflected length of the tail pointer of data message that CPU3 is processed is k, and deflected length k is stored
To in global variable Z.After upper-layer protocol process completes data message, it is long that CPU1 obtains skew in global variable X for the record
Degree m, according to this deflected length m, the tail pointer of data message is offset backward.In the same manner, CPU2 and CPU3 can also be correctly extensive
The position of the multiple handled tail pointer of data message.
In the present embodiment, member device receives during the data message carrying private data it may be necessary to utilize this private
Data is had to be used as Business Processing or control message to forward, for example, private data includes the list item forwarding this data message, now,
Member device can length based on pre-configured above-mentioned private data, read above-mentioned privately owned from the message tail of this data message
Data.
After this member device obtains above-mentioned private data, this data message is no longer necessary to carry above-mentioned private data, this
When, above-mentioned private data can be abandoned, by this measure, this data message, when being swapped out distributed apparatus, is reduced to
Original message content.
As shown in figure 1, private data length length5 is pre-configured on all member devices, any member equipment exists
When needing using private data, can be after receiving the data message carrying private data, according to private data length
Length5, by the tail pointer biased forwards of message buffer to position D, reads this private data.Read after the completion of, because after
Without private data, the position of tail pointer is no longer moved on to position E to continuous equipment by member device, keeps tail pointer in D position, will
This data message forwarding goes out distributed apparatus.
In sum, in this application, the member device of distributed apparatus send protocol stack by record data message upper
Upper-layer protocol when, point to data message the tail pointer of message buffer deflected length, upper-layer protocol process after the completion of,
The position of tail pointer can be recovered, and above-mentioned data message forwarding set to next member according to the above-mentioned deflected length of record
For so that the member device of subsequently received above-mentioned data message can obtain the private data carrying in above-mentioned data message.
