In this demonstration we will show the prospects of dynamic cloud service placement. A cloud service is implemented that manages real-time video streaming and real-time control commands for a remote controlled drone. The requirements for this cloud service are groundbreaking because the image transfer and the control commands should be transmitted in real time that the drone can be controlled smoothly...
A video streaming system with over-the-top delivery has to select the servers that handle the service requests such that the content is delivered with the desired quality and system resources are efficiently used. Server selection can be formulated as a multi-criteria optimization problem, but solving this problem requires dynamic information about system resources. In this paper, we study the performance...
Software Defined Networking is a promising Internet architecture to deliver multimedia with end-to-end quality of service (QoS) since it enables optimal dynamic management of network resources and on-demand QoS provisioning by a network operator. We propose a framework for server load-balancing over a single-operator OpenFlow network to improve the quality of service levels of video streaming services...
The shortcomings of today's Internet and the high demand for complex and sophisticated applications and services drive a very interesting and novel research area called Future Internet. The area of Future Internet research focuses on developing a new network with similar magnitude as today's Internet but with more demanding and complex design goals and specifications. It strives to solve the issues...
Wireless monitor system are widely used in recent years, but there are a few problems to solve, such as scalability and adaptability, and monitor system based on MANET has more difficulties because of multi-hop links and mutable channels. A new MANET monitor system based on Service-oriented architecture (MMS-SOA) is proposed to make the system easier to manage dynamically such as dynamic deployment,...
Mobile video service is emerging as an attractive service, on basis of the successful IPTV commercialization and recent incredible smart-phone penetration to the mobile market. However, the lack of QoE/QoS monitoring mechanism will be a major obstacle for wider acceptance. In this paper, we present a QoE/QoS monitoring scheme, extending OMA-DM protocol and streaming QoE parameters. The design and...
In the design of mobile phone monitoring system, the balance of real-time video playback fluency and clarity is the key of the design work. For this problem, the designer can use image data compression international standard, such as MPEG standards, and real-time transport protocol RTP to reallize real-time video data transmission on GPRS, but the final result is extremely poor. On the basis of introducing...
The main idea of this paper is using a manager server on the top of the tree-based P2P network construction for smartly providing alternative parent peers to reconnect in a case, when the downloading parent is down or crashes. The solution for these issues is considered to use minimum reconnection time for the parent change and solving the problem as lack in alternative peers. This is one of the main...
Development of network monitoring tools for realtime rich-media (RTRM) applications remains a challenge for both academic and industrial researchers as the complexity of the computational processing varies dynamically. We propose a novel, flexible and cost effective technique which can be implemented in ordinary network environment to monitor QoS parameters such as packet-delay, packet-loss, packet...
This paper builds on an interactive streaming architecture that supports both user feedback interpretation, and temporal juxtaposition of multiple video bitstreams in a single streaming session. As an original contribution, these functionalities can be exploited to offer improved viewing experience, when accessing football content through individual and potentially bandwidth constrained connections...
Qinghai Lake Natural Protection Zone is a sanctuary for migratory birds, but also a focal point in global concerns of avian influenza. In order to support the research about migratory birds, we planned to set up a remote monitoring system in Qinghai Lake. The development of this system refers to some techniques about GIS(geographic information system), J2EE and ActiveX. This web video monitor system...
For the requirements of remote monitoring and nobody on duty , a basic structure of the remote video monitoring system in power substation is discussed. MPEG2/4 protocol is used as the compression way for its better adaptability. Combing with the network multicast technology and TCP/IP protocol, the video stream can be transmitted in real time. The communication scheme based on GOOSE (Generic Object...
Based on the analysis of QQLive protocol, an active monitoring based QQLive real-time information acquisition system was presented by the in-depth study of characteristic message and characteristic payload in the communication process of QQLive. The system acquires the channel list and program information, at the same time monitors the viewing user information by forging the client to send message...
Todaypsilas Internet relies on best-effort delivery in which no guarantees regarding transmission quality are employed. This is problematic in the field of video streaming due to its sensitiveness to transmission quality fluctuations. The ability to measure the experienced level of quality of service (QoS) is valuable in streaming applications. By utilizing the information from QoS measurements, the...
Today more and more video is transmitted over IP network and mainly peer-to-peer network. But peer-to-peer solutions can not transmit high quality and high resolution video stream as HDTV. For this we have to create reliable architecture and solve different problems. Our main idea is using manager server in the top of the tree construction for smartly providing alternative parent peers for a case...
Application streaming is technology to stream the code of an application from a central server and run it on a client computer without downloading and installation. The application can be executed while streaming of the application code may still be in progress. However, since the software streaming is based on networks, its service is affected by network failures. Network failures may cause the streamed...
A multi-server video monitor system based on streaming media communication technology is proposed. Large-scale, long-distance monitoring requirements have been met. The video monitor software is researched, which has the function of video restoration, proprietary protocol is used to realize video transmitting smoothly. In the part of the software programming, multi-threaded mechanism and double buffering...
