Tomorrow's immersive applications will leverage Mixed Reality interfaces accessing a multitude of services from distributed clouds. They will face extreme latency constraints, massive datasets, spontaneous collaboration, and constant service churn. This paper outlines our experience evolving an application designed to support collaborative work in Urban Design (UD) practices. The application, UD Co-Spaces,...
Modern internet traffic is heavily composed of some form of video communication. In addition, video streaming is slowly replacing regular phone connections. Given that most video transport utilizes Video over Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP), it is important to understand TCP performance in transporting video streams. Recently, multipath transport protocols have...
Most of the recent set-top boxes for digital video broadcasting connect to the Internet. They can receive data from broadcasting systems and from the Internet. Such hybrid broadcasting environments, in which clients can receive data from both broadcasting systems and communications systems, are suitable for streaming delivery since they complement their demerits for streaming delivery with each other...
This paper describes an implementation of a runtime environment for portable message-passing C programs with Message Passing Interface (MPI) library on web browsers. We have implemented core functions of the library. The runtime system runs several MPI programs without any modification. We confirm that the runtime performances of the programs are comparable to their native executions on some conditions.
The ubiquity of the Internet and email, have provided a mostly insecure communication medium for the consumer. During the last few decades, we have seen the development of several ways to secure email messages. However, these solutions are inflexible and difficult to use for encrypting email messages to protect security and privacy while communicating or collaborating via email. Under the current...
The use of Deep Packet Inspection (DPI) equipment in a network could simplify the conventional work load for system management and accelerate the control action. The authors proposed a congestion control method that uses a DPI device installed in a network to estimate overload conditions of servers or network links and, upon detecting an overload condition, resolves congestion by moving some virtual...
