Open vSwitch


Licensed under open source Apache 2.0, Open vSwitch is a multi-layered, enterprise grade virtual switch born specifically to be used in modern virtual networks of a virtual environment. This is similar to a virtual bridge of Linux but has more ability and robust features. A question often asked is why one should choose Open vSwitch over time and industry-proven traditional Linux bridge and networking. Once we understand the features and advantages Open vSwitch provides for a virtual network, the answer becomes obvious.

Features of Open vSwitch

The following are some of the features that make Open vSwitch a better option than standard Linux networking:

  • Security: Open vSwitch provides a high-degree of security by allowing you to set policies per VM virtual interface.

  • LACP and VLAN-aware: Open vSwitch fully supports the LACP link aggregation and VLAN tagging. We can configure one single Open vSwitch with multiple VLAN tags, thus reducing management overhead of many virtual bridges...
