Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
The technical background of the embodiment of the present invention is described below.
Fig. 1 is referred to, is the schematic diagram that dns server carries out domain name mapping in the prior art.First, in dns server
DNS processes need to switch to kernel state by User space, and the SOCKET interfaces provided by system in dns server intercept report
Text；When dns server receives the query message for requesting query IP address, DNS processes are waken up, and are switched by kernel state
For User space；Because the query message that dns server is received is stored in the internal memory for only allowing the process in kernel state to access
Space, and query message can only be in the DNS processes processing of User space, therefore DNS processes are also needed to by SOCKET interfaces
Query message is copied to the memory headroom for allowing the process in User space to access, query message could be handled.
DNS processes have been handled after the query message and generated according to result after response message, in addition it is also necessary to will by SOCKET interfaces
Response message copies to the memory headroom for allowing the process in kernel state to access, and then can just be sent to corresponding user and set
It is standby.Wherein, DNS processes often handle one query message and are required for switching state at least twice, relatively complicated, and it also requires entering
The duplication of row query message and response message, very elapsed time.Wherein, this is the process for handling a DNS query message,
It is contemplated that, when DNS query message is more, then it is likely to many pending DNS query messages of accumulation so that user domain
Name access speed is slower, influences the usage experience of user.And it is obvious, the speed for handling a DNS query message is slower, then DNS
The QPS of server is also lower, and the possibility of domain name resolution service can not normally be provided by also increasing dns server.
In consideration of it, the embodiment of the present invention provides a kind of message processing method, in the method, message processor receives the
After one message, in the shared drive that can be able to access that the first packet storage to the first process in User space, such
One process then can directly read the first message from shared drive and carry out Message processing, without again by the first process by
One message is copied in the memory headroom that the first process can be accessed, and then improves treatment effeciency.Also, in the processing of the first process
After complete first message, also it so can also avoid the need for the first process by response message storage into shared drive and switch shape again
State replicates response message, equally improves treatment effeciency, so as to lift the speed of domain name mapping, improves dns server
QPS.
Technical scheme provided in an embodiment of the present invention is introduced below in conjunction with the accompanying drawings.
Fig. 2 is referred to, one embodiment of the invention provides a kind of message processing method, and the flow of this method is described as follows：
In embodiments of the present invention, message processor can receive and dispatch and handle any equipment of message, for example
Message processor can be dns server etc..The message processor can include first thread, packet sending and receiving thread and be total to
Internal memory is enjoyed, certainly, first thread, packet sending and receiving thread and shared drive can also be not arranged within message processor.Under
Face is illustrated so that message processor can include first thread, packet sending and receiving thread and shared drive as an example.
Step S201：Message processor intercepts the report that packet sending and receiving process is received by the first process in kernel state
Text.
In embodiments of the present invention, when message processor is not received by message, message processor can then pass through
First process intercepts message in message processor.Wherein, because message processor receive message be stored in
The memory headroom that the process of core state could be accessed, if therefore the first process can not listen to message, then in User space
First process then by User space can be switched to kernel state by message processor when not having outstanding message.Specifically, report
The application programming interface that literary processing equipment can be provided by the first process through the operating system in message processor
(Application Programming Interface, API) calls kernel, to switch to kernel state.Wherein, API is for example
Can be NETLINK interfaces.
In embodiments of the present invention, when message processor is dns server, the first process can be then DNS service
DNS processes in device.
Step S202：User equipment sends the first message to message processor, and message processor passes through packet sending and receiving
Process receives the first message.
When user equipment needs the first message of processing, user equipment then can send the first message to message processor,
For example when user equipment needs to carry out domain name access, DNS query message can be then sent to dns server by user equipment, with
The corresponding IP address of the DNS query domain name is asked, and then user equipment could conduct interviews according to the IP address.Correspondingly, report
Literary processing equipment can receive the first message that user equipment is sent by packet sending and receiving process.
Step S203：Message processor is by packet sending and receiving process by the first packet storage to shared drive.
After message processor receives the first message by packet sending and receiving process, then message processor can pass through
Packet sending and receiving process is by the first packet storage received to shared drive.Wherein, packet sending and receiving process is one and is in all the time
The process of kernel state, that is to say, that packet sending and receiving process is the kernel spacing operated in message processor, therefore message
Transmitting-receiving process can directly receive the first message, and can be by the first packet storage in shared drive.Shared drive is this
A part of memory headroom that inventive embodiments are marked in the internal memory of message processor, and the partial memory space is arranged to
The memory headroom that the process of User space can also be accessed.
In embodiments of the present invention, when message processor is dns server, packet sending and receiving process can be then DNS
Fast-turn construction DNS processes in server.Wherein, fast-turn construction DNS processes are used to collect message and will handle the response message forwarding completed
To corresponding user equipment.
Step S204：Message processor is sent to the first process by packet sending and receiving process and indicates message, Message processing
Equipment is received by the first process and indicates message.
When message processor by packet sending and receiving process by the first packet storage to shared drive after, packet sending and receiving is entered
Cheng Ze can send to the first process and indicate message, to inform that the first process packet sending and receiving process has received the first message and deposited
Storage.Wherein, the message that packet sending and receiving equipment is received may have multiple, therefore, and packet sending and receiving process can be with one message of every storage
All sent afterwards to the first process and indicate message.Certainly, in order to reduce the interactive quantity of packet sending and receiving process and the first process, message
Transmitting-receiving process can just send to the first process after first message that storage is received and indicate message, and continuously receive afterwards
Message do not send instruction message then.Accordingly, message processor can receive the instruction message by the first process.
Specifically, the API that packet sending and receiving process can be provided by operating system sends to the first process and indicates message, example
NETLINK interfaces described above.
Step S205：Message processor reads the first message by the first process from shared drive.
Specifically, because the first process in kernel state can not be handled the first message, therefore in message
Processing equipment is received by the first process after instruction message, and message processor first can be cut the first process by kernel state
It is changed to User space.
Message processor by the first process after kernel state switches to User space, message processor can then lead to
Cross the first process and the first message is read from shared drive.Because the data stored in shared drive are can be by the of User space
What one process was accessed, therefore the first process can directly read the first message from shared drive, without again by first
Message, which is copied to, could continue follow-up processing in the memory headroom that the first process can be accessed, it is clear that compare duplication first and report
Text, the embodiment of the present invention directly reads the first message from the communal space and obviously more saves the time.
In embodiments of the present invention, in order to ensure that the message stored in shared drive can be processed successively in sequence,
Therefore the data structure that stored messages are used in shared drive is without lock data structure.It is of course also possible to use can realize
Other the possible data structures for the function that message can be processed successively in sequence, the embodiment of the present invention is not limited this
System.Wherein, message can be processed successively in sequence refers to that the first process, when reading message, can be stored from shared drive
First start of heading of message queue read, after the completion of first message is processed, next message then becomes first
Individual message, the like, that is to say, that the message that the first process is read is first message being in message queue all the time.And
In packet sending and receiving process stored messages, can by the packet storage newly received in message queue backmost.Wherein, received in message
It is also similar during hair process transmission response message, i.e., packet sending and receiving process can read first response message in response message queue
And corresponding user equipment is sent to, response message can be also stored in response message by the first process when storing response message
Queue it is last.
Specifically, the embodiment of the present invention without lock data structure in addition to it can realize above-mentioned functions, it is also possible that read
Take message and storage response message can be while carrying out, it is not necessary to which addend carries out data protection according to lock, then can prevent from reading
Thread is suspended when message or storage response message, and then can not continue reading message or storage response report next time
Text, therefore the speed for reading message by using may also speed up without lock data structure or storing response message.
Step S206：Message processor handles the first message by the first process, and response report is generated according to result
Text.
In embodiments of the present invention, after message processor reads the first message by the first process, Message processing
Equipment handles the first message by the first process, and generates response message according to result.For example, when message processor is
During dns server, the DNS processes in dns server are read after the first message, then the information inquiry that can be included according to the first message
Corresponding IP address, and response message is generated according to Query Result.
Step S207：Response message storage is arrived shared drive by message processor by the first process.
In embodiments of the present invention, message processor by the first process by response message storage to shared drive it
Afterwards, message processor can also determine to whether there is the second pending message in shared drive by the first process.If
Message processor determines there is the second pending message in shared drive by the first process, then message processor then can
The first process is continued through to read from shared drive and handle the second message；And if message processor passes through the first process
Determine that message processor is switched the first process by User space without any the second pending message in shared drive
For kernel state, to continue to intercept message by the first process in kernel state.Wherein, because the first process has handled the first report
After text, response message is sent without switching to kernel state, but shared drive is arrived into response message storage, such first enters
Cheng Ze can handle other messages stored in shared drive, without frequently switching state, it is clear that more save the time.Example
Such as, when message processor is dns server, then the DNS processes in dns server can continue processing DNS query message,
Without frequently switching DNS states of a process, then the lifting that the speed of domain name mapping obviously can be bigger, accordingly, DNS clothes
The QPS of business device can also get a promotion accordingly.Meanwhile, also carried not necessarily like needing to put into more hardware resources in the prior art
The QPS of dns server is risen, it is more cost-effective, save manpower.
Step S208：Message processor sends response to packet sending and receiving process by the first process and indicates message, message
Processing equipment receives response by packet sending and receiving process and indicates message.
Response message storage is arrived by shared drive by the first process in message processor, entered in order that obtaining packet sending and receiving
Response message is transmitted to user equipment by journey in time, then message processor can be provided by the first process through operating system
API sends response to packet sending and receiving process and indicates message, and the message of process first is received and dispatched by the first process with notice message
Reason is completed, and has been stored on shared drive.Wherein, API for example can be above-mentioned NETLINK interfaces.
Step S209：Message processor reads response message by packet sending and receiving process from shared drive.
Step S210：Response message is sent to user equipment by message processor by packet sending and receiving process.
In the embodiment of the present invention, because message processor directly can be read by packet sending and receiving process from shared drive
Response message is simultaneously sent to corresponding user equipment, without as also need in the prior art by the first process also need to by with
Family state switches to kernel state, then the response message that response message is sent in corresponding user equipment, the embodiment of the present application is sent out
The process sent more saves the time.
In embodiments of the present invention, in order to realize further beneficial effect, step 208~step S210 is increased, although
Shown in the lump in figure, but the beneficial effect of the application can just be realized by going to s207, i.e., carried while workload is reduced
Rise the QPS of dns server.
In summary, in embodiments of the present invention, can be by the first message after message processor receives the first message
Store in the shared drive that the first process in User space is able to access that, such first process then can be directly from shared interior
Deposit the first message of middle reading and carry out Message processing, can be with without the first message is copied into the first process by the first process again
In the memory headroom of access, and then improve treatment effeciency.Also, can also be by response after the first process has handled the first message
Packet storage also avoids the need for into shared drive, so the first process, and switching state replicates response message again, equally carries
High treatment effeciency, so as to lift the speed of domain name mapping, improves the QPS of dns server.
