OPEN APPLICATION
DELIVERY USING SDN
While current SDN-based efforts are mostly
restricted to L3 and below (network traffic),
it may be extended to manage L3 and above application
traffic as well. Application traffic management
involves enforcing application deployment
and delivery policies on application traffic flows that may be identified by the type of application,
application deployment context (application partitioning
and replication, intermediary service
access for security, performance, etc.), user and
server contexts (load, mobility, failures, etc.),
and application QoS requirements. This is
required since delivering modern Internet-scale
applications has become increasingly complex
even inside a single private data center.
