Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present invention clearer, a virtual network optimization method based on general receiving package and shared authorization page of the present invention will be further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] The platform adopted for realizing the object of the present invention includes CPU, memory, network card and other resources as the virtualized infrastructure. The platform runs a virtual machine monitor, which provides virtualization services. The virtual machine monitor implements the host virtual network based on the network card, and provides a virtual network and network equipment for the virtual machine. Virtual network devices are used by virtual machines to provide network access fu...

Abstract

The invention relates to a method for optimizing a virtual network, including a grouping step, an unpacking step and a sharing authorization page step, wherein: the grouping step is to form a combined network package with packets having the same source and destination link addresses, and generate a combined network package ; The step of sharing the authorization page, receiving the combined network packet, and copying the combined network packet to the front-end driver of the virtual machine; The unpacking step, receiving this combined network packet from the front-end driver, and determining the combination according to the I / O response For the small network packet in the network packet, the combined network packet is split, and the small network packet obtained after the splitting is handed over to the upper-layer network protocol stack for processing. The present invention optimizes the overall performance of network virtualization by means of receiving end grouping and sharing authorization pages.

Description

technical field [0001] The invention relates to the field of network virtualization, in particular to a virtual network optimization method and system. Background technique [0002] Virtualization is the basic technology of cloud computing, and network virtualization is an important support of virtualization technology, which has a crucial impact on the overall efficiency of cloud computing platforms. The performance optimization of network virtualization is very challenging. High-speed network devices need to send and receive a large number of network packets in a very short time interval, and the processing of each network packet is inevitably accompanied by additional virtualization overhead. The sending process of the virtual network can be optimized by methods such as downshifting, zero copy, and Nagle algorithm optimization. However, due to the particularity of the virtual network software stack, there are few optimization methods available for the receiving process, r...
