Summary

This paper argues that putting networked end-systems into low-power sleep modes, instead of keeping them in higher-power-consuming idle states, can result in significant energy savings. … Continue Reading ››

A. Qureshi, R. Weber, H. Balakrishnan, J. Guttag, B. Maggs, "Cutting the Electric Bill for Internet-Scale Systems," ACM SIGCOMM Conference, (August 2009). [PDF]

Summary

Large organizations like Google, Microsoft, and Yahoo! annually consume tens of millions of dollars worth of electricity. The traditional approach toward reducing energy costs by reducing the amount of energy consumption … Continue Reading ››

Y. Zhao, Y. Xie, F. Yu, Q. Ke, Y. Yu, Y. Chen, E. Gillum, "BotGraph: Large Scale Spamming Botnet Detection," NSDI'09, (April 2009). [PDF]

Summary

Analyzing large volume of logged data to identify abnormal patterns is one of the biggest and most frequently faced challenges in the network security community. This paper presents BotGraph, a … Continue Reading ››

R. Gummadi, H. Balakrishnan, P. Maniatis, S. Ratnasamy, "Not-a-Bot: Improving Service Availability in the Face of Botnet Attacks," NSDI'09, (April 2009). [PDF]

Summary

In recent years, botnets have become the major originators of email spams, DDoS attacks, and click-frauds on advertisement-based web sites. This paper argues that separating human-generated traffic from botnet-generated activities can improve … Continue Reading ››

S. Banerjee, B. Bhattacharjee, C. Kommareddy, "Scalable Application Layer Multicast," ACM SIGCOMM Conference, (August 2002). [PDF]

Summary

Deployment of network layer multicast requires support from the underlying infrastructure. Like many other proposals/protocols with similar requirements, it faced the same fate: no one deployed it. This paper presents a scalable application layer multicast protocol, NICE, designed … Continue Reading ››

S. Floyd, V. Jacobson, S. McCanne, C-G Liu, L. Zhang, "A Reliable Multicast Framework for Light-weight Sessions and Application Level Framing," ACM SIGCOMM Conference, (August 1995). [PDF]

Summary

Unlike unicast transmissions where requirements for different reliable, sequential data delivery are fairly general, different multicast applications have different requirements for reliability. The authors argue that designing … Continue Reading ››

R. Fonseca, G. Porter, R. H. Katz, S. Shenker, I. Stoica, "X-Trace: A Pervasive Network Tracing Framework," NSDI'07, (April 2007). [PDF]

Summary

Diagnosing problems in modern distributed and networked systems is notoriously hard due to the involvement of multiple administrative domains, application and network protocols, and lack of determinism and reproducibility. X-Trace is a cross-layer, … Continue Reading ››

G. Watson, N. McKeown, M. Casado, "NetFPGA: A Tool for Network Research and Education," 2nd Workshop on Architecture Research using FPGA Platforms (WARFP), (February, 2006). [PDF]

Summary

Building custom hardware systems for conducting network experiments as well as for educational purposes is complex and expensive. On the other end of the spectrum, software routers like … Continue Reading ››

D. Joseph, A. Tavakoli, I. Stoica, "A Policy-Aware Switching Layer for Data Centers," ACM SIGCOMM Conference, (August 2008). [PDF]

Summary

Middlebox (e.g., firewalls, load balancers etc.) management in existing data center networks is inflexible and require manual configuration by system administrators, which result in frequent misconfigurations. This paper presents a policy-aware switching layer (PLayer) in … Continue Reading ››

I. Stoica, D. Adkins, S. Zhuang, S. Shenker, S. Surana, "Internet Indirection Infrastructure," ACM SIGCOMM Conference, (August 2002). [PDF]

Summary

Internet Indirection Infrastructure (i3) is an overlay network that offers a rendezvous-based communication abstraction to decouple the act of sending from the act of receiving in order to support diverse communication services (e.g., multicast, anycast, … Continue Reading ››
