Abstract
The invention discloses a multichannel network message transmission method, comprising the following steps of: respectively mapping each network card message buffer queue to a user space by using multiqueue network card hardware, wherein each thread of application program or multiple application programs can simultaneously and respectively operate corresponding queue; respectively carrying out DMA (Direct Memory Access) on the message into the corresponding buffer queue by using the performance of host multicore CPU (Central Processing Unit); and then informing the network card to carry out sending process through a flow control mechanism. The multichannel network message transmission method has the following beneficial effects that the whole transmission process realizes the zero participation of the CPU in the network message sending process, and high-efficient wire speed sending is carried out in Gbit/10Gbit network environment; therefore, the method alleviates the load of a multichannel message sending system and improves the performance of system sending message.
Description
Technical field
The present invention relates to the network communications technology, particularly a kind of multichannel network message transmitting method of multichannel zero-copy
Background technology
In network security, the network detecting, fields such as network test, the data transmission method for uplink of high-speed and high-efficiency is the problem of industry primary study.In existing technology; Transmitted data on network is realized through protocol stack; Though this method can guarantee the versatility in the general operation system; But because data transmission procedure need send through kernel, the low and waste system resource of the speed of giving out a contract for a project prior art in current Gbit and following 10Gbit Ethernet can not satisfy current application demand.
Summary of the invention
The technical problem that the present invention solved provide a kind of in the network message process of transmitting zero the participating in of central processing unit, alleviated the load of multichannel transmitting system, improved system and sent the multichannel network message transmitting method of the performance of message.
For solving the problems of the technologies described above, multichannel network message transmitting method provided by the invention is following:
The a plurality of message buffering formations of NIC driver application are used for sending and receiving message;
Utilize many formations characteristic of polycaryon processor network interface card hardware, be mapped to user's space to each network interface card packet buffer formation respectively, each thread of application program or a plurality of application programs can be operated corresponding queues simultaneously respectively.Utilize the performance of main frame multi-core CPU, respectively message DMA in its corresponding cache formation.
Send processing through a kind of flow-control mechanism notice network interface card then.
The good effect that the present invention had is: whole transmission course realizes zero participation of central processing unit in the network message process of transmitting; In the network environment of Gbit/10Gbit, carrying out efficiently linear speed gives out a contract for a project; Alleviate the load of multichannel transmitting system, improved the performance that system sends message
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is a multichannel network message transmitting method schematic diagram of the present invention;
Fig. 2 is a multichannel network message transmitting method FB(flow block) of the present invention.
Embodiment
Like Fig. 1, shown in Figure 2, multichannel network message transmitting method provided by the invention is following:
