Network Services Headers (NSH): Creating a Service Plane for Cloud Networks

In the past, we have pointed out that configuring network services and security policies into an application network has traditionally been the most complex, tedious and time-consuming aspect of deploying new applications. For a data center or cloud provider to stand up applications in minutes and not days, easily configuring the right service nodes (e.g. a load balancer or firewall), with the right application and security policies, to support…
