|
This optimization installs <strong>Open vSwitch (OVS)</strong>, a multilayer virtual switch
|
||||||
Provides advanced networking capabilities, including VLAN tagging, trunking,
|
designed for modern virtualized environments. OVS enhances network management by enabling
|
||||||
traffic shaping, and Quality of Service (QoS). OVS enables more flexible and scalable network configurations,
|
advanced features for virtualized infrastructures.
|
||||||
making it ideal for complex virtualization setups requiring fine-grained traffic control.
