S203, message is handled using User space protocol stack.
S204, message is handled using kernel state protocol stack.
S205, upper level applications are transferred to handle message.
Detailed process are as follows: network interface card receives message, according to the rule of user setting, judges whether to need User space agreement
Stack, if it is, otherwise entering kernel state protocol stack into the processing of User space protocol stack and handling, handed over after the completion of protocol stack processing
It is handled by upper level applications.
Fig. 3 is that the dual stack of the embodiment of the present invention is given out a contract for a project flow chart.As shown in figure 3, the dual stack of the present embodiment is sent out
Packet receiving method may include the following contents.
S301, upper level applications message.
S302, User space protocol stack processing rule whether is matched.
Judge whether to match User space protocol stack processing rule, if YES, then executes S303, otherwise, execute S304.
S303, message is handled using User space protocol stack.
S304, message is handled using kernel state protocol stack.
S305, network interface is transferred to send message.
Detailed process are as follows: upper level applications will send message, according to user setting rule, judge whether to need using use
Family state protocol stack, if it is, otherwise enter kernel state protocol stack into the processing of User space protocol stack and handle, protocol stack processing
After the completion, it is sent from network interface.
In this implementation, on the one hand, by unified kernel state protocol stack interface and User space protocol stack interface, facilitate using journey
The transplanting of sequence source program.On the other hand, realize it is single using multi-protocol stack and deposit, application program source program can local transplantation, reduce
Transplanting workload.Therefore, technical solution provided in this embodiment, for needing the application program using User space protocol stack,
It only needs to do simple interface according to User space protocol stack and replace, application program source program portable workload is small, and system performance is high.
Method as described above, it is preferred that include protocol stack flag bit, institute in the type parameter of User space protocol stack interface
Protocol stack flag bit is stated for identity protocol stack type.Specifically, during development of user state protocol stack, application program creation set
When connecing word, the protocol stack flag bit of a User space protocol stack, application program other sockets are added on the basis of type parameter
Word correlation function is then not necessarily to change.It further, whether include protocol stack flag bit according in the type parameter of protocol stack interface
Judge agreement stack type；According to the agreement stack type judged, increase protocol stack flag bit on the filec descriptor of return.Again
Further, protocol stack is selected according to the protocol stack flag bit on the filec descriptor of return, and on removing filec descriptor
Protocol stack flag bit after call selection protocol stack function.
In the present embodiment, without using the Frame Design and codimg logic of the source program of User space protocol stack, for needing
Use the application program source program of User space protocol stack, it is only necessary to simple interface be done according to User space protocol stack and replaced.Replacement
Work includes:
(1) when application program creation socket, a protocol stack flag bit is added on the basis of type parameter.
(2) the other socket correlation functions of application program are without change.
(3) the socket correlation function of application program adapter system, using with POSIX standard accordant interface.
For creating socket, whether there will be agreement stack marker according to original type parameter, and carry out the set of different agreement stack
Word judgement is connect, increases protocol stack flag bit newly on the filec descriptor of return.
Flag bit is being removed by according to the protocol stack flag bit on filec descriptor for other socket correlation functions
Afterwards, the function of different agreement stack is called.
Method as described above, it is preferred that the message transmissions rule, comprising: if type of message is control stream, use
Kernel state protocol stack handles message；If type of message be data flow, using User space protocol stack to message at
Reason.
The scheme of the present embodiment, kernel are only used to handle control stream, and all data flow relevant operations are all carried out in User space
Processing to evade the performance bottlenecks such as the packet copy of kernel, thread scheduling, system calling, interruption, and is aided with various Performance tunings
Means, to reach higher performance.
