Whitepaper: Virtual Teaming: Experiments and Experiences With Distributed Pair Programming

by North Carolina State UniversityJan 01, 2008

Distributed team projects are becoming more common in the software industry. The power of distributed development can increase an organization’s opportunities to win new work by opening up a broader skill and product knowledge base, coupled with a deeper pool of potential employees. This paper discusses results of the research on Distributed Pair Programming (dPP). By dPP the paper means that two members of the team (which may consist solely of these two people) synchronously collaborate on the same design or code from different locations.

Whitepaper: CUBIC: A New TCP-Friendly High-Speed TCP Variant

by North Carolina State UniversityJan 01, 2008

This white paper elaborates on a new TCP variant, called CUBIC, for high-speed network environments. CUBIC is an enhanced version of BIC, it simplifies the BIC window control and improves its TCP-friendliness and RTT-fairness. The window growth function of CUBIC is governed by a cubic function in terms of the elapsed time since the last loss event. Furthermore, the real-time nature of the protocol keeps the window growth rate independent of RTT, which keeps the protocol TCP friendly under both short and long RTT paths.

Whitepaper: MTCP: Scalable TCP-Like Congestion Control for Reliable Multicast

by North Carolina State UniversityJan 01, 2008

As the Internet becomes more diversified in its capabilities, it becomes feasible to develop and offer services and applications that were not possible under earlier generations of Internet technologies. The paper presents MTCP, a congestion control scheme for large-scale reliable multicast. Congestion control for reliable multicast is important, because of its wide applications in multimedia and collaborative computing, yet nontrivial, because of the potentially large number of receivers involved. Many schemes have been proposed to handle recovery of lost packets in scalable manner, but there is little work on the design and implementation of congestion control schemes for reliable multicast.

Whitepaper: Antenna Selection in High-Throughput Wireless LAN

by North Carolina State UniversityJan 01, 2008

This research paper by North Carolina State University presents a new method for implementing antenna selection in high-throughput Wireless LANs (WLANs), addressing two major practical concerns: antenna selection training protocol design, and calibration to solve RF imbalance problems. Specifically, the low Doppler spread of WLAN channels enables to train all antenna subsets by multiple training packets transmitted in burst; consequently antenna selection techniques can be accommodated in the emerging standards with minimum modifications. In order to deal with RF imbalance, it proposes a novel calibration procedure that reduces the performance degradations.
