Safety is crucial for people, and emergency management helps keep people safe. Emergency management involves four stages: Planning and Mitigation, Preparedness, Response and Recovery. Geospatial applications (including GIS) have been extensively used in each stage of emergency management. Decision-makers can utilize the geospatial information to develop planning and mitigation strategies. ...

While Internet video control and data planes have received much research attention, little is known about the video management plane. In this paper, using data from more than a hundred video publishers spanning two years, we characterize the video management plane and its evolution. The management plane shows significant diversity ...

Modern engineering incorporates smart technologies in all aspects of our lives. Smart technologies are generating terabytes of log messages every day to report their status. It is crucial to analyze these log messages and present usable information (e.g. patterns) to administrators, so that they can manage and monitor these technologies. ...

With the development of Web 2.0, ubiquitous computing, and corresponding technologies, social media has the ability to provide the concepts of information contribution, diffusion, and exchange. Different from the permitting the general public to issue the user-generated information, social media has enabled them to avoid the need to use centralized, ...

Speech separation and pitch estimation in noisy conditions are considered to be a "chicken-and-egg" problem. On one hand, pitch information is an important cue for speech separation. On the other hand, speech separation makes pitch estimation easier when background noise is removed. In this paper, we propose a supervised learning ...

Cloud infrastructures provide a rich set of management tasks that operate computing, storage, and networking resources in the cloud. Monitoring the executions of these tasks is crucial for cloud providers to promptly find and understand problems that compromise cloud availability. However, such monitoring is challenging because there are multiple distributed ...

We envision a real-time network traffic map for the Internet, where each network link is annotated with its capacity and its current utilization, with an interface that networked applications can query to inform their control decisions. While this goal is simple to state, it has been out of our reach ...

There is a growing recognition among researchers, industry practitioners, and service providers of the need to optimize user-perceived application experience. Network infrastructure owners (i.e., ISPs) have traditionally been left out of this equation, leading to repeated tussles between content providers and ISPs. In parallel, application providers have to deploy complex ...

Troubleshooting Software-Defined Networks requires a structured approach to detect mistranslations between high-level intent (policy) and low-level forwarding behavior, and a flexible on-demand packet tracing tool is highly desirable on the data plane. In this paper, we introduce a Layer 2 path tracing utility named PathletTracer. PathletTracer offers an interface for ...

User-created live video streaming is marking a fundamental shift in the workload of live video delivery. However, live-video-specific challenges and the viral nature of user-created content makes it difficult for current CDNs to deliver 1) high-quality, 2) highly-scalable, and 3) highly-responsive service. We present the design and implementation of VDN, ...
