People favor network distance education because this education is not restricted to time and place, besides it develops rapidly in recent years. While there is no denying that network distance education exists the shortcoming of the separation between teachers and students. So how to guarantee teachers and students' communication in real-time in the network distance education activities so that students...
The portion of video traffic in the total amount of Internet traffic has been increased. As the number of users and volume of content are increased, the content providers had been suffered for processing and transferring media and they have adopt CDN technology into their service so that their burden can be alleviated. The CDN technology can be classified into three different types; ‘server farm CDN’,...
Many laboratories were set up in Chinese higher education institutions in recent years. Some of them in the same university are equipped with similar rigs, which may lead to waste of money and human power in their setup and maintenance, and inconvenience and inefficiency for both faculties and students. An experimental teaching and management system, Open Laboratory Access (OLA), based on cloud computing...
SIP-based Voice Over IP(VoIP) network is becoming predominant in current and future communications. Distributed Denial of service attacks pose a serious threat to VOIP network security. SIP servers are victims of DDos attacks. The major aim of the DDos attacks is to avoid legitimate users to access resources of SIP servers. Distributed Denial of service attacks target the VOIP network by deploying...
Omni Media has become an important trend with the development of information services in the context of network convergence and screen integration. In such an environment, Internet interaction is no longer limited to the computer, users can also access Internet resources through wearable and other smart computing devices. This paper proposes a multimedia repository system, which is composed of client...
The heterogeneity of the network poses new challenges on the paradigm of multimedia content distribution. Nowadays, different access technologies coexist in user terminals, so it is possible to improve the performance or avoid coverage problems by switching from one to another. This process is known as handover. In this work we have focused on vertical handover, which is the process of switching between...
With rapid progress in information and communication technology (ICT), the existing communication infrastructure has been continually evolving. Telecommunication network operators may need to expand hardware and software infrastructure to adopt new communication technologies, which will require considerable capital investments. In addition, devices for Internet of Things (IoT) are being rapidly adopted...
We developed a robust approach that can be synchronized with accuracy to a media streaming group in a network congestion situation. This approach consists of a server-side and client-side algorithm. The server-side algorithm is used to transmit the playback information using a synchronization control packet to clients. The synchronization control packet is transmitted in an event-driven manner. The...
In this paper, we propose an effective method for transmitting multimedia based NFV to ensure required quality when a large amount of traffic for multimedia occur in the multimedia transmission, and user needs. We designed a network structure NFV using OpenStack and then created VM, network connection, and upload images through the dashboard. We used network simulation OPNET to measure the performance...
Quality of Experience (QoE) support becomes more demanding due to the increasing popularity of multimedia services. However, QoE-based multimedia provisioning will impose a high pressure on server capacity and network bandwidth, which becomes one of the major concerns for both content providers and network operators. A common approach for efficient and scalable multimedia service provisioning in content...
This paper introduces the distributed multimedia system and its characteristics, discusses the application of distributed multimedia system in the field of teaching, And distributed multimedia system management mode in colleges and universities are discussed in this paper. The traditional multimedia equipment management in the real world problems is analyzed, and put forward some improvement measures...
Recent years, data transfer via www is one of the most popular application and web traffic on the Internet consumes much network resources. We have proposed a peer-to-peer cache distribution system to reduce consumption of network resources so far. Systems based on our proposal enable peers to receive a part of the data while the peers are downloading data from a server. In this paper, we report further...
Real-time interactive communications have become critical for business, e-commerce, e-government and education. Teleconferencing systems have been usually deployed using proprietary and expensive systems. Overlay networks are often used to support multi-point teleconferencing and provide services unavailable in the underlying physical networks. With the advent of WebRTC, real-time communication applications...
With the evolution of technologies such as WebRTC and telecommunication (Telco) architectures aligned with the latest 3GPP standards, the search for interoperability between traditional and web-oriented endpoints is vital, with new use-cases and multimedia services to be explored. Currently, convergence goes beyond the standards and, as such, its search and the technological obstacles motivate this...
Software Defined Networking (SDN) and Named Data Networking (NDN) are two topics which have received lots of attention in the networking research community in recent years. While both have emerged independently from each other we believe that their core features can be well aligned to each other. Hence combining both may hold potential benefits for network operators. In this paper we investigate the...
MPEG published a new international standard, MMT (MPEG Media Transport) for efficient transport of MPEG media over all IP networks in June 2014. This paper shows its potential as standard for adaptive media service system. We applied this standard to video streaming system and shows its efficiency transmission in limited resource network environment. The system has been tested in harsh condition such...
MPEG Media Transport(MMT) has being standardized in SC29/WG11 MPEG as a next generation media transport in all IP environments. This paper proposed a true-realtime system based on MMT features. This true-realtime system minimizes the delay between generation of a content in the server and display in the client within 10s ms if there is no network jitter. This paper includes object and temporal design...
This paper introduces a novel content classification scheme in video-on-demand (VoD) based on the emerging standard of MPEG media transport (MMT). Content classification is necessary and reasonable, due to the fact that a better user experience may be obtained if the requested video is organized and presented in different ways according to various user requirements and/or video popularities. For this...
Mobile eLearning are capable to avail children in improving learning capabilities, self-consciousness living, and profession growth. They can inspire the perfection of eLearning with the diverse subservient smart handled devices. Most available software applications that are attainable by children are done without taking in consideration their needs and specific deficiency. We have investigated Arabic...
The popularity of multimedia services offered over the Internet have increased tremendously during the last decade. The technologies that are used to deliver these services are evolving at a rapidly increasing pace. However, new technologies often demand updating the dedicated hardware (e.g., transcoders) that is required to deliver the services. Currently, these updates require installing the physical...
