Enabling Network throttling for VMs on Hyper-v

Bug Reference

CLOUDSTACK-6262

Branch

4.4, Master

Introduction

Network throttling is the process of controlling the network access and bandwidth usage based on certain rules. It controls the maximum bandwidth which can be allocated to VM. The benefit here is that you may have very noisy VMs on host that consume a lot of bandwidth, and they can be stepped down yet still given an adequate amount of connectivity.

Purpose

This is functional specification for Enabling Network throttling for VMs on Hyper-V

Document History

Glossary

VM - virtual machine running on hypervisor

NIC - network interface controller which is attached to VM

Feature Specifications

• Currently network rate parameter which is passed during deployment of VM is not honored in Hyper-V. With this we will apply that parameter to maximum bandwidth allowed for VM. This parameter will be applied to NIC and controls the max data transfer date rate of the NIC and will apply to both ingress and egress traffic combined .
• One can see whether settings got applied successfully by verifying the VM -> settings--> network adapter --> bandwidth management --> maximum bandwidth in Hyper-V Manager.
• To see how network throttling rate applies on VM see network throtling .
  
  

Use cases

With this we can control the max bandwidth allocated for VM
