چکیده

To reduce the impact of large-sized, high-rate (α) transfers on real-time flows, a Hybrid Network Traffic Engineering System (HNTES) was proposed in earlier work. HNTES is an intra-domain solution that enables the automatic identification of α flows at a provider network’s ingress routers, and redirects these flows to traffic-engineered QoS-controlled virtual circuits. The purpose of this work is to determine the best QoS mechanisms for the virtual circuits used in this application. Our findings are that a no-policing, two-queues solution with weighted fair queueing and priority queueing is both sufficient and the best for this application. It allows for the dual goals of reduced delay/jitter in real-time flows, and high-throughput for the α flows, to be met. Keywords—policing; scheduling; high-speed networks; trafficengineering; virtual-circuit networks

Traffic Engineering and Characterization of High-Rate Large-Sized Flows

High-rate large-sized (α) flows have adverse effects on delay-sensitive flows. Research-andeducation network providers are interested in identifying such flows within their networks, and directing these flows to virtual circuits. To achieve this goal, a design is proposed for a hybrid network traffic engineering system (HNTES) that would run on an external server, gather NetFlow records from ro...

On how to provision Quality of Service (QoS) for large dataset transfers

There is recent interest in using traffic-engineered, QoS-controlled paths for large-sized, high-rate dataset transfers in the scientific community. We refer to TCP flows created by such transfers as α flows. Research-and-education network providers are interested in intra-domain traffic engineering systems for identifying α flows at ingress routers within their networks, and redirecting them t...

Design of a Low-Latency Router Based on Virtual Output Queuing and Bypass Channels for Wireless Network-on-Chip

Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...

On Using Virtual-Circuit Networks for File Transfers

It has become clear that widespread collaboration in the scientific community, which can increasingly be characterized by geographically distributed and large-scale projects, requires predictable network service [1]. Predictable network service needed by applications such as large file transfers, remote visualization, and remote instrumentation can only be offered on connection-oriented network...

Moving Towards Generally Applicable Redirected Walking

Walking is the most natural way of moving within a virtual environment (VE). Mapping the user’s movement one-to-one to the real world clearly has the drawback that the limited range of the tracking sensors and a rather small working space in the real word restrict the users’ interaction. In this paper we introduce concepts for virtual locomotion interfaces that support exploration of large-scal...
