The emergence of 5G wireless and IoT (Internet of Things) technologies, as well as the continuous evolution of cloud computing is driving the need for easy and on-demand creation of end-to-end network services. We have developed an integrated system called the end-to-end network service orchestrator, which realizes seamless service orchestration across multiple on-premises and cloud infrastructures...
The massive adoption of cloud-based services in data center lead to an exponential increasing in both the amount traffic and servers, which brings a great challenge to data center network (DCN). In this paper, MOSA: a modular all-optical switching architecture based on arrayed waveguide gratings (AWG) is proposed to address the issue. The modular design makes MOSA can expand up to millions of servers...
Data center networks become increasingly important with the growth of cloud computing. For any integers k ≥ 0 and n ≥ 2, the k-dimensional DCell, Dk,n, has been proposed for one of the most important data center networks as a server-centric data center network structure. In this paper, we propose an efficient algorithm for finding disjoint paths in node-to-set routing...
Smartphones have been widely integrated with GPS receiver, which may provide accurate location information of vehicles without cost increase. Traditionally, LBS applications obtain vehicle locations then using the Hypertext Transfer Protocol (HTTP) protocol uploaded to central servers with a fixed frequency. In this paper, we exploit an intelligent strategy of GPS sensing and transmitting. Explicitly,...
Geographic stereo video includes both spatial and temporal geographic features acquired through ground-based or non-ground-based cameras. This paper aims to design and develop the geographic stereo video web service system. Firstly, the paper reviews on the state of arts of geographic video and geographic stereo video, analyzes the REST architectural style. The application requirement of geographic...
In this paper, we show through detailed simulations that BitTorrent can be used to assist a server or content distribution network (CDN) for large-scale streaming delivery. Specifically, a content owner can distribute a file to over 131,072 users/peers with a peak swarm size of 16,384 concurrent users and a CDN bandwidth savings of 73%, while achieving an average user buffer time of under 2 seconds,...
