(routers or switches). In OpenFlow, network devices store the flows
and their associated rules in flow tables, which are processed as a
pipeline. Its goal is to reduce the packet processing time.
Optimization of Dynamic QoS Routing
e dynamic QoS routing can be regarded as a constrained short-
est path (CSP) problem. It is crucial to select a cost metric and con-
straints, where they both characterize the network conditions and
support the QoS requirements. In multimedia applications, the typi-
cal QoS indicators are packet loss, delay, and delay variation (jitter).
However, some QoS indicators may differ depending on the type of
application, such as follows: (1) interactive multimedia app ...
