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 network resources of a virtual machine in a multicore-based network interface card, and a multi-core-based network in an environment in which two or more virtual machines are operated in a multi-core-based server. When applying data transmission and processing algorithms using an interface card, network resources are used according to the traffic volume regardless of the core resources contracted by each virtual machine, and other virtual machines host problems affected by the use of network resources. QoS for virtual machine network resources is guaranteed by adding QoS module, NIC QoS module, and thread management module to obtain QoS information from hypervisor and dynamically allocating threads to each virtual machine based on QoS information. It relates to a virtual machine QoS guaranteed data transmission method in a multicore-based network interface card, characterized in that it provides a structure and method that can be done.
