Abstract
The invention discloses an acceleration network card for a cloud computing application layer. The acceleration network card for the cloud computing application layer comprises a network card chip, a network interface and a host bus interface, wherein the network card chip is connected with the network interface and the host bus interface; a multi-core processing module is cured in the network card chip 1; a network protocol stack is cured in the multi-core processing module; the network interface is connected with a network; and the host bus interface is connected with a host. According to the acceleration network card, a multi-core technology is adopted, and the network protocol stack is cured in the network card chip, so that high-efficiency network transmission is realized; in the same situation, the concurrent access of more users and shorter transmission delay can be realized by a server, the deployment scale of the server can be reduced, and energy resources are saved; the supporting of application protocol processing is realized in hardware, so that the processing burden of the central processing unit (CPU) is uninstalled, and the efficiency of the system is improved; and the functions such as protocol stack timer management and message verification and computation can be realized in the hardware of the network card, and the access delay of the server can be reduced obviously.
Description
Technical field
The present invention relates to the network communications technology, particularly a kind of acceleration network interface card that is applicable to the cloud computing application layer of express network.
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.And the present network communications technology can not satisfy the demands under the express network fast development trend.In present scheme, common network interface card is received the network data that needs service, informs processor through the mode of interrupting; Computer cpu handles through the tcp/ip protocol stack; Submit to application layer service to business datum and handle, cpu calculates the business that the core application layer service is correlated with again, when needs transmission new data is given the equipment that needs service; Through the tcp/ip protocol stack, send through network interface card again.Because in the present scheme, cpu has handled it and has been bad at the tcp/ip business, cause the professional ability drop of its its processing core.In view of this, present common network interface card exists following shortcoming: 1, because common network interface card lacks the ability of network data, cause the frequent response to network message of cpu to interrupt, expended a large amount of cpu times, cause inefficiency; 2, the copy of network data from the kernel spacing to the application space taken a large amount of memory bus bandwidth; Timer management and cache management in the 3 operating system protocol stacks need consume a large amount of cpu resources; 4, on the server of the many computation core of many cpu of main flow, need between a plurality of computational threads, carry out assignment of traffic, be difficult to realize effective load balancing.
Summary of the invention
The technical problem that the present invention solved provides a kind of how concurrent, and low energy consumption can realize the acceleration network interface card of the low cloud computing application layer that postpones of high bandwidth.
For solving the problems of the technologies described above, the acceleration network interface card of cloud computing application layer of the present invention comprises with the lower part: network card chip, network interface, host bus interface.
Network card chip is connected with network interface and host bus interface.
Wherein, the multinuclear processing module is solidificated in the network card chip, and network protocol stack is solidificated in the multinuclear processing module;
Network interface links to each other with network, and host bus interface links to each other with main frame.
Network card chip adopts the polycaryon processor system CPU.
The cloud computing application layer is quickened integrated fire compartment wall in the network interface card.
The acceleration network interface card of cloud computing application layer is to insert memory bar.
The good effect that the present invention had is: adopt multi-core technology, be solidificated in network protocol stack on the network card chip, realize Network Transmission more efficiently; Under the square one, server can be realized the concurrent visit of more users, shorter transmission delay; Reduce the server disposition scale, energy savings; Protocol stack complete discharge, all working are to realize in the network interface card the inside, can in hardware, realize handling burden to using the support of protocol processes thereby unload cpu, improve the efficient of system; Application layer procedure is not always made any modification, because the change of interface, former network interface card possibly need application program to do modify; Hardware is realized protocol stack timer management and functions such as message checking and calculating in network interface card, can obviously reduce the delay of server access.
