Integration von Signalisierungsmechanismen zur Dienstgütereservierung in einem SIP-Client
The IETF's Next Steps in Signaling (NSIS) Working Group specified network signaling protocols for the Internet. Two different signaling applications are currently standardized---the QoS NSLP establishes Quality-of-Service (QoS) resource reservations on network nodes while the NAT/FW NSLP is used to configure NAT gateways and firewalls. All parts of the NSIS protocol suite were implemented at the Institute of Telematics and evaluated in different scenarios. In order to use Voice-over-IP telephony in the Internet, the Session Initiation Protocol (SIP) is commonly used as an application signaling protocol.
The main task of this thesis is to couple both, the NSIS and the SIP protocols, to initiate and maintain a QoS resource reservation, such that for the initial SIP negotation on the application layer resources are reserved on the network layer by means of the NSIS protocols.
In order to start soon, some programing knowledge in C++ is of big advantage.
