We typically address the ‘scale question’ by working closely with our clients to define ‘scale’ for separate components that may have different scale needs based on their requirements:
- Scale of the controller for multi-tenant network virtualization (aka network slicing)
- Scale of the approach to multi-tenancy (aka encapsulation, VXLAN, VLANs, etc)
- Scale of the vSwitch and physical infrastructure for expected traffic patterns and customer types
- Scale of the L3 – L7 network services in multi-tenant, virtualized network environment
As you may imagine, based on specific functional requirements, how one answers these questions may be quite different. Meaning the solution for a multi-tenant datacenter application for a cloud service provider may (has) quite different requirements than a virtual CPE that leverage a multi-tenant security services delivered via a service provider POP.
During our research for one project we met the 6WIND team, reviewed their approach to solving parts of the scale problem around vSwitches and L3-L7 network services and asked them to share their view on SDNCentral.
For those who don’t know, 6WIND is a leading provider of networking software that addresses scale and performance challenges for physical and virtual networks.
6WIND authored a blog post for SDNCentral, to examine and explain SDN performance from 6WIND’s point of view while describing some benefits specific to 6WIND.
