QoS in 4G scenarios using NSIS protocol

Resumo

This paper presents quality of service mechanisms, based on the NSIS (Next Steps In Signaling) protocol. For that, it was implemented a testbed with NSIS running through IPv6. The network’s QoS was measured by the number of drops, for each flow (either QoS or Best Effort traffic), occurred in routers. The first experiment shows the captured packets during a node association and request for QoS, namely a GIST session and a QoS NSLP session. The second experiment illustrates a more realistic scenario, where different flows with different QoS parameters and Best Effort traffic, were simultaneously sent through a path across different networks. The experimental study addressed in this work helped on the enhancement of NSIS developments forIPv6 environments.
