QoS Device and Method for Data Transmission and QoS Guarantee of Virtual Machines in Multicore-based Network Interface Card

摘要

The present invention relates to a data transmission apparatus and method for guaranteeing QoS for a network resource of a virtual machine in a multicore-based network interface card, in a multicore-based network in an environment in which two or more virtual machines are operated in a multicore-based server When using the interface card to apply data transfer and processing algorithms, each virtual machine uses the network resource according to the traffic volume regardless of the core resource contracted to host the problem that other virtual machines are affected by the network resource usage. QoS module, NIC QoS module, and thread management module are added to obtain QoS information from the hypervisor and dynamically allocate threads for each virtual machine based on the QoS information, guaranteeing QoS for network resources of the virtual machine It relates to a virtual machine QoS guaranteed data transmission method in a multi-core-based network interface card characterized by providing a structure and a method capable of.
