              Application-aware Networking (APN) Framework
                       draft-li-apn-framework-01

Abstract

   A multitude of applications are carried over the network, which have
   varying needs for network bandwidth, latency, jitter, and packet
   loss, etc.  Some new emerging applications (e.g. 5G) have very
   demanding performance requirements.  However, in current networks,
   the network and applications are decoupled, that is, the network is
   not aware of the applications' requirements in a fine granularity.
   Therefore, it is difficult to provide truly fine-granularity traffic
   operations for the applications and guarantee their SLA requirements.

   This document proposes a new framework, named Application-aware
   Networking (APN), where application characteristic information such
   as application identification and its network performance
   requirements is carried in the packet encapsulation in order to
   facilitate service provisioning, perform application-level traffic
   steering and network resource adjustment.
