UFO: A Resilient Layered Routing Architecture
White Paper Despite scaling rather well, today's Internet routing system does not react quickly to changing network conditions. Overlay networks, on the other hand, can respond quickly to changing network conditions, but their reliance on aggressive probing... [11 Jul 2008]
FT-LAN, a Fault Tolerant Local Area Network Architecture for Mobile Mission Critical Systems
White Paper It is desirable that they continue to perform a subset of critical tasks under fault conditions. A key consideration for MMCS's is the ability of the network to support critical operations during fault conditions. [11 Jul 2008]
Traffic Engineering With Traditional IP Routing Protocols
White Paper Traffic engineering involves adapting the routing of traffic to the network conditions, with the joint goals of good user performance and efficient use of network resources. This paper describe an approach to intradomain traffic engineering that... [11 Jul 2008]
Dynamic Bandwidth Allocation for Multimedia Traffic With Rate Guarantee and Fair Access in WCDMA Systems
White Paper Packet scheduling in a WCDMA system poses a new challenge due to its nature of variable bit rates and location-dependent, time-varying channel conditions. In this work, three new downlink scheduling algorithms for a WCDMA base station are proposed... [11 Jul 2008]
Scalability and Accuracy in a Large-Scale Network Emulator
White Paper This paper presents ModelNet, a scalable Internet emulation environment that enables researchers to deploy unmodified software prototypes in a configurable Internet-like environment and subject them to faults and varying network conditions. [11 Jul 2008]
On the Interaction Between Dynamic Routing in the Native and Overlay Layers
White Paper This paper is concerned with scenarios where a dynamic routing protocol is employed in the overlay network to adapt overlay routing tables to changing network conditions. Overlay networks have recently gained attention as a viable alternative to... [11 Jul 2008]
High-Bandwidth Video Conferencing Systems: When Is the Quality Worth the Cost?
White Paper An experiment was conducted investigating the subjective perception of video quality under the following conditions: 384 kbps, 1920 kbps, DVTS, and plain video. The marketing literature for videoconferencing products often makes recommendations for... [11 Jul 2008]
Packet Buffer Management for a High-Speed Network Interface Card
White Paper Dynamic buffer management techniques are more efficient than the static ones because they change the threshold value according to network traffic conditions. Packet buffers in a smart network interface card are managed in a way to reduce any packet... [11 Jul 2008]
On Orthogonal Reduction to Hessenberg Form With Small Bandwidth
White Paper This paper studies necessary and sufficient conditions on A so that the orthogonal Hessenberg reduction yields a Hessenberg matrix with small bandwidth. Numerous algorithms in numerical linear algebra are based on the reduction of a given matrix A... [11 Jul 2008]
The Myth of Bandwidth and Application Performance
White Paper At the application level, performance is likewise limited by factors such as: the natural behavior of application protocols that were not designed for WAN conditions; application protocols that engage in excessive handshaking; and the... [11 Jul 2008]
Scalability of Two Reliable Multicast Protocols
White Paper The findings confirm that SRM scales poorly under some conditions: to obtain reliability, the protocol incurs overhead linear in group size and throughput fluctuates erratically. Growing demand for multicast communication in large network settings... [11 Jul 2008]
On the Scalability and Capacity of Planar Wireless Networks With Omnidirectional Antennas
White Paper And if there are scalable patterns of wireless networks, what are the conditions that govern their scalability? Scalability of wireless networks has been an important research topic in the recent years, because of the growing demand to support a... [11 Jul 2008]
Comparison of Available Bandwidth Estimation Techniques in Packet-Switched Mobile Networks
White Paper TOPP, SLoPS and pathChirp, taking into account the statistical conditions of the available bandwidth and assessing the variability of their estimations. The relative contribution of the transport network towards the per-user capacity in mobile... [11 Jul 2008]
Artificial Intelligence - alive and kicking
News These include applications such as engine management systems in cars which use elements of AI to react as road conditions change. Artificial intelligence technology (AI) is being used all around us but don't expect any philosophical discussions... [10 Jul 2008]
Streaming Stored Continuous Media Over Fair-Share Bandwidth
White Paper To obtain typical fair-share bandwidth conditions, a series of Internet experiments is performed in which the paper monitors TCP bulk-data transfers between various sites, and collect average TCP throughput traces. [10 Jul 2008]
