QoS-adaptation by software agents in the presence of defective reservation mechanisms in the Internet

چکیده
Originally, the Internet delivered best-eeort service quality with respect to end-to-end delay. Recently, extensions such as RSVP have been proposed to provide guaranteed real-time services as well. Unfortunately, network resources, such as routers, do not yet fully support RSVP reservation protocols so that guarantees cannot truly be given. In this paper , we suggest to follow the paradigm of open programmable networks for a more complete QoS provisioning. Reservation gaps or tunnels are dynamically closed by means of a software-agent approach that is exibly deployed for an application oriented QoS support. Agents are dynamically located to such tunnels in order to monitor the tunnels, to provide feedback information in case of QoS violations, and to decide on possible compensating measures to be taken.

Tunnel agents for enhanced Internet QoS
Heterogeneous networking will soon become a reality. Even though new technologies, such as asynchronous transfer mode (ATM), inherently guarantee Quality of Service provisioning, they will continue to use protocols from the TCP/IP world. Consequently, the Internet world needs QoS provisioning. System developers recently have proposed Internet extensions, such as the resource reservation protoco...

متن کاملAdvanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
متن کاملAn agent-based approach for QoS provisioning to mobile users in the Internet
Although Internet implicitly assumed stationary users, nowadays user mobility represents a new variable to be taken into account when designing new services or defining new reference architectures. Mobile users wish to access all the services available in the Internet possibly with the same quality with which these services are accessed through a desktop computer. The provision of QoS guarantee...
