As networking researchers, we love to work on ideas that improve the practice of networking. In the early pioneering days of the Internet the link between networking researchers and practitioners was strong; the community was small and everyone knew each other. Not only were there many important ideas from the research community that affected the practice of networking, we were all very aware of them.

Expanding home services with advanced gateways

The success of over-the-top (OTT) services reflects users' demand for personalization of digital services at home. ISPs propose fulfilling this demand with a cloud delivery model, which would simplify the management of the service portfolio and bring them additional revenue streams. We argue that this approach has many limitations that can be fixed by turning the home gateway into a flexible execution platform. We define requirements for such a "service-hosting gateway" and build a proof of concept prototype using a virtualized Intel Groveland system-on-a-chip platform.

Networked services for backup, photos, music, videos, communications, security, and more are rapidly making inroads in the home. What is the best architecture with which to deliver these services? This paper argues in favor of an architecture that leverages compute and storage at the home gateway, rather than solely in the cloud and on consumer electronics devices in the home. All of the reviewers felt that this was a timely and well-written paper that would engage the research community in a new and quickly evolving area. The main benefit of the paper is the case it makes for home service gateways, along with a report on a prototype home service gateway in which virtualization is used to enable multiple services to co-exist. The main weakness of the paper is that none of the reviewers were convinced by the argument. Each reviewer raised a different but overlapping set of issues. Two reviewers thought that the privacy and performance benefits of home gateways were overstated. Two reviewers thought that the economic cost of adding computing to the home should be factored into the argument. One reviewer thought that the market issues dominated the technical issues of the home gateway in practice, leaving the paper somewhat moot. However, all the reviewers felt that paper advanced the topic, and that publishing it would let readers participate in the debate.

ASTUTE: Detecting a Different Class of Traffic Anomalies

When many flows are multiplexed on a non-saturated link, their volume changes over short timescales tend to cancel each other out, making the average change across flows close to zero. This equilibrium property holds if the flows are nearly independent, and it is violated by traffic changes caused by several, potentially small, correlated flows. Many traffic anomalies (both malicious and benign) fit this description. Based on this observation, we exploit equilibrium to design a computationally simple detection method for correlated anomalous flows.

Yet Another Access Point

Increasing popularity in personal access points and travel routers has begun to rise with the advent of smaller and more battery conscious devices. This article introduces the YAAP (Yet Another Access Point), an open source software that enables ad-hoc infrastructure services in the absence of network connectivity. The YAAP provides a familiar way to connect users to each other and provides a set of useful services. We list and describe its applications, explain how it can be used, provide details about the code, and point readers to where it can be downloaded.

Ranking of ACM SIGCOMM Computer Communication Review

ACM SIGCOMM Computer Communication Review (CCR – www.sigcomm.org/ccr/) fills a unique niche in the spectrum of computer communications literature. It seeks to quickly publish articles containing high-quality research, especially new ideas and visions, in order to allow the community to react and comment. CCR is unique in that its reviewing process turn-over is less than 3 months, which guarantees a timely publication of high quality scientific articles.
