Embodiment
Functional overview
Consider exist in the correlation technique problem, the present invention proposes a kind of many formations message method of sending and receiving and device based on Zero-copy mode.
Under the normal condition, a message queue is respectively used in the transmission of message, reception.Like this, when a plurality of application programs are carried out the transmission of message simultaneously or received operation, just need carry out mutually exclusive operation to message queue.For head it off, we create a plurality of message queues, and each application program is determined employed message queue number by parameter.Like this, each application program can be used the message queue of oneself simultaneously.Concerning each application program, except needing the specified queue extra when the function call, the situation of other aspects during fully with a message queue is identical.
Send and receive operation by applying for a plurality of message buffer formations and adopting Zero-copy mode to carry out message, made full use of the disposal ability of multi-core CPU, guarantee all homology chummages of message that a plurality of application programs receive, do not adopted mutually exclusive operation, improved the treatment effeciency of message.
Fig. 1 is the flow chart according to the many formations message method of sending and receiving based on Zero-copy mode of the present invention.As shown in Figure 1, the many formations message method of sending and receiving based on Zero-copy mode according to the present invention comprises:
Step S102, the NIC driver application is used to send and receive a plurality of message buffer formations of message;
Step S 104, when network interface card receives message, adopt Zero-copy mode to receive message, and the message that is received is stored in a plurality of message buffer formations in the corresponding message buffer formation; And when network interface card sends message, specify message to store in which message buffer formation in a plurality of message buffer formations, adopt Zero-copy mode to carry out message then and send.
Wherein, when network interface card receives message, can carry out Hash operation, carry out the storage of message then, to guarantee the homology chummage of message according to source IP address in the heading that is received and purpose IP address.
Wherein, hash algorithm is exactly the binary number that extracts fixed position, fixed qty at first respectively from 32 bits of source IP address, purpose IP address, such as 12 to 20 totally 9 figure places, then this group number is carried out xor operation, and get the remainder operation according to number of queues.Like this, just different messages can be stored in the different message queues, also guarantee the homology chummage of message simultaneously.
Wherein, when network interface card sends message, can move one or more application programs simultaneously and carry out transmit operation, each application program is used different message buffer formations.
Fig. 2 is according to the many formations message sending and receiving device based on Zero-copy mode of the present invention.As shown in Figure 2, the many formations message sending and receiving device 200 based on Zero-copy mode according to the present invention comprises: formation application module 202 is used to apply for being used to send and receive a plurality of message buffer formations of message; Message receiver module 204 is used for when network interface card receives message, adopts Zero-copy mode to receive message, and the message that is received is stored in a plurality of message buffer formations in the corresponding message buffer formation; And message sending module 206, when network interface card sends message, specify message to store in which message buffer formation in a plurality of message buffer formations, adopt Zero-copy mode to carry out message then and send.
Wherein, when receiving message, the message receiver module carries out Hash operation according to source IP address in the heading that is received and purpose IP address.When sending message, to move one or more application programs simultaneously and carry out transmit operation, each application program is used different message buffer formations, like this, does not need to carry out mutually exclusive operation.
In sum, by above-mentioned at least one technical scheme of the present invention, by by applying for a plurality of message buffer formations and adopt Zero-copy mode to carry out message to send and receive operation, the present invention has made full use of the disposal ability of multi-core CPU, all homology chummages of message that a plurality of application programs receive have been guaranteed, do not adopt mutually exclusive operation, improved the treatment effeciency of message.。
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the storage device and carry out by calculation element, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
