Load Balanced Virtual Switches (Erl, Naserpour)

How can workloads be dynamically balanced on physical network connections to prevent bandwidth bottlenecks?

Load Balanced Virtual Switches

Problem

When network traffic on the uplink port for a virtual switch increases, it can cause delays, performance issues and packet loss because the affected virtual servers are sending and receiving traffic via only one uplink.

Solution

Network traffic is balanced across multiple uplinks between the virtual and physical networks.

Application

Extra network interface cards are added to the physical host to accommodate the virtual switch that is configured with multiple physical uplinks.

Mechanisms

Cloud Usage Monitor, Hypervisor, Load Balancer, Logical Network Perimeter, Physical Uplink, Resource Replication, Virtual Infrastructure Manager, Virtual Server, Virtual Switch
