Quality of Service (QoS) support for real-time traffic is a critical issue in high speed networks. The previously proposed Delay-Limiter Switch working with the Framed-Deadline Scheduler (FDS) is a combined input-output queuing (CIOQ) packet switch that can provide end-to-end bandwidth and delay guarantees for connection-oriented traffic. The Delay-Limiter Switch works with fixed-size packets. It has a scalable architecture and can provide QoS support for connection-oriented real-time traffic in a low-complexity fashion. The Delay-Limiter Switch serves connectionless traffic by using the remaining resources from the connection-oriented traffic. In this case, efficient management of the residual resources plays an important role on the performance of the connectionless traffic. This thesis work integrates new methods to the Delay-Limiter Switch that can improve the performance of the connectionless traffic while still serving the connection-oriented traffic with the promised QoS guarantees. A new method that makes it possible for the Delay-Limiter Switch to support variable-sized packets is also proposed.

Hardware design and implementation of packet fair queuing algorithms for the quality of service support in the high-speed internet Sanli, Mustafa; Schmidt, Şenan Ece; Guran, Hasan Cengiz (2012-09-05) The increasing amount of real-time traffic carried over the Internet requires end-to-end quality of service (QoS) support. To this end, the QoS Schedulers, that are implemented in routers, assign the available bandwidth resources to packet flows according to their respective allocated rates. Packet Fair Queuing (PFQ) schedulers can provide fair service and low end-to-end delay bound to the traffic flows. However, they have higher implementation complexity compared to other algorithms, because of the require...
Frame-counter scheduler: A novel QoS scheduler for real-time traffic Schmidt, Şenan Ece (Elsevier BV, 2006-08-04) Real-time traffic communication has Quality of Service (QoS) requirements such as end-to-end bandwidth and delay guarantees.
Reroute sequence planning in multiprotocol label switching networks Özbilgin, İzzet Gökhan; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2004) The growth of the Internet has caused the development of new protocols that enable IP networks to be engineered efficiently. One such protocol, Multiprotocol Label Switching (MPLS) enables IP datagrams in backbone networks to be forwarded based on the label switching forwarding paradigm. In MPLS networks, rerouting of Label Switching Paths (LSPs) can be needed in order to attain a better resource utilization in the network. In this case, a sequence of LSPs has to be found for their one by one reconfiguratio...
Software implementations of QoS scheduling algorithms for high speed networks / Pehlivanlı, Aydın; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2015) The end to end Quality of Service (QoS) support for the dominating multimedia traffic in the contemporary computer networks is achieved by implementing schedulers in the routers and deploying traffic shapers. To this end, realistic modeling and simulation of these components is essential for network performance evaluation. The first contribution of this thesis is the design and implementation of a C++ simulator QueST (Quality of Service simulaTor) for this task. QueST is a modular cycle accurate simulator w...
Parallel and pipelined architectures for high speed ip packet forwarding Erdem, Oğuzhan; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2011) A substantial increase in the number of internet users and the traffic volume bring new challenges for network router design. The current routers need to support higher link data rates and large number of line cards to accommodate the growth of the internet traffic, which necessitate an increase in physical space, power and memory use. Packet forwarding, which is one of the major tasks of a router, has been a performance bottleneck in internet infrastructure. In general, most of the packet forwarding algori...
