28. Capability Defines how a network adapter is able to use its connection
Quality of service
Security
Monitoring
Capabilities are provided by Hyper-V Extensible Virtual Switch and extensions

29. Key Tenets for Hyper-V Extensible Switch
Benefit
Extensible, not replaceable
Added features don’t remove other features
Pluggable switch
Extensions process all network traffic, including VM-to-VM
1st class citizen of system
Live Migration and offloads just work; Extensions work together
Open & public API model
Large ecosystem of extensions
Logo certification and rich OS framework
High quality extensions
Unified Tracing thru virtual switch
Shorter down times

30. Hyper-V Extensible Switch
Extensions are Filters or Windows Filtering Platform Providers
Extension state/configuration is unique to each instance of an Extensible Switch on a machine
