Load Balanced Virtual Switches (Erl, Naserpour)

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

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.
Load Balanced Virtual Switches: The addition of network interface cards and physical uplinks allows network workloads to be balanced.
