Abstract:
As the number of network services and applications increases, each one of them showing different requirements
in terms of bandwidth and latency, it becomes critical for network operators to identify these applications.
This paper builds up on the principles of Software Defined Networking, proposing a novel Application-
Aware Network architecture, which is able to directly handle applications and their requirements; abstracting
the complexity of dealing with network flows. Since metadata about applications are signalled either directly
from the endpoints or from application managers, the information is precise and the approach can also be
used for encrypted traffic. The benefits of the Application-Aware Approach for the network flow management
is demonstrated in real network by two proof-of-concept services: aimed on quality of experience and load
balancing.
