Application-aware Networking (APN) Framework
2020
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.
