• Apply settings for load
• Create IP pool as a

Networking Scenarios
Key Tenets
Extensible, not replaceable
Pluggable switch
1st class citizen of system
Open & public API model
Logo certification and rich OS
framework
Unified Tracing thru virtual switch
Benefit
Added features don’t remove other
features
Extensions process all network traffic,
including VM-to-VM
Live Migration and offloads just work;
Extensions work together
Large ecosystem of extensions
High quality extensions
Shorter down times
Extensions are Filters or
Windows Filtering Platform
Providers
Extension state/configuration
is unique to each instance of
an Extensible Switch on a
machine
