Network Card Virtualization System and Method Based on Hardware Queue Expansion

Abstract

The invention discloses a network card virtualizing system on the basis of hardware array expansion, which is used for multi-core network processor platform and comprises an interface management module, a virtual interface driving module and a network driving module. The network card virtualizing system is characterized in that virtual interfaces in the virtual interface driving module are formed by an independently-interrupted hardware array, the hardware array is bound with a physical network card, and the virtual interface driving module is used for providing the virtual interfaces for a partitioned operation system, and the interface management module, the virtual interface driving module and the network driving module are interacted in a controlled manner through an inter-area communication mechanism. Independent interruption of the hardware array is substituted for interruption capture and simulation process in the software realizing scheme in the network card virtualizing system, so that the network card virtualizing system has excellent performance under the environment with multiple virtual interfaces.

Description

technical field [0001] The invention belongs to the field of IO virtualization in system virtualization, and in particular relates to a network card virtualization system based on hardware queue expansion on a multi-core network processor platform and a method thereof. Background technique [0002] In recent years, the computing power of computer hardware has continued to rise, and the cost of hardware has dropped, resulting in a large increase in cheap hardware. A series of practical problems related to it have become the focus of the current industry: rising management costs, low security, and low utilization of resources. The virtualization technology has the characteristics of isolation, mergeability, and migration, and is considered to be the best solution to optimize the basic IT architecture of the current industry and solve the above-mentioned practical problems. [0003] Although virtualization technology has many advantages, its application in the industry still f...
