Running multi-OS on a physical machine is the major method to improve the utilization of computer. With the widely use of virtualization technology in cloud computing, the efficiency of inter-domain communication becomes the key factor for performance of distributed applications especially for some network-intensive applications. The communication synchronous mechanism used by traditional VMM is based...
This article presents an approach towards aggregating bandwidths of multiple physical layers i.e. transmitting and receiving data simultaneously through the multiple physical interfaces of a fixed computing system. The data over physical layers can communicate over both wired and wireless communication medium at the same time. This proposed bandwidth-aggregation-system (BWA) enhances the download...
Noncontiguous I/O access is one of the main access patterns in parallel and distributed applications. An I/O architecture EXIO enables Globus, a popular run-time environment for distributed computing, on RDMA networks such as InfiniBand. In this paper, we investigate the benefits of InfiniBand zero-copy RDMA to noncontiguous I/O on Globus. Our experimental results demonstrate that, by enabling zero-copy...
Although Transmission Control Protocol (TCP) is a widely deployed and successful protocol, it shows some limitations in present-day environments. In particular, it is unable to exploit multiple (physical or logical) paths between two hosts. This paper presents PATTHEL, a session-layer solution designed for parallelizing stream data transfers. Parallelization is achieved by striping the data flow among...
The conventional TCP suffers from poor performance on high bandwidth delay product links meant for supporting data transmission rates of multi Gigabits per seconds (Gbps). This is mainly due to the fact that during congestion, the TCP's congestion control algorithm reduces the congestion window cwnd to frac12 and enters additive increase mode, which can be slow in taking advantage of large amounts...
Within the next 10-15 years, air-traffic management (ATM) will be primarily based on data communications and voice communication will be mostly used as fallback solution. Furthermore, it is foreseen that IP-based networking solutions for A/G communication will be deployed for cost savings, high reliability and an optimal alignment with the evolution of communication and security technologies. Such...
