The classification of unstructured P2P multicast video streaming is the premise for playing online linkage and real-time evidence in the process of network monitoring management. A new classification method is demonstrated, and some real-time protocol behavior features are figured in this paper, which is found out through distinguishing packet type and transmission direction. With these accessible...
The session initiation protocol (SIP) is an application-layer control protocol for creating, modifying, and terminating sessions with one or more participants in the IP-based telephony environment.Yang et al. and Huang et al. proposed a secure authentication scheme for session initiation protocol.Yang's scheme is based on Deffi-Hellman key agreement scheme and a combination of hash functions. In 2006,...
The development of assessment management system has been discussed for a long time. The motivation always focuses on the evaluation of learners' ability or on the difficulties of examination. The common examination content could be composed by text or simple figures, and the assistant functionalities could also be developed to meet the individual needs. But these functionalities couldn't interoperate...
The existing QoS mechanisms for video streaming are short of the consideration for various user environments and the characteristic of streaming applying programs. In order to overwhelm this problem, studies on the video streaming protocols exploiting scalable video coding (SVC), which provide spatial, temporal, and qualitative scalability in video coding, are progressing actively. However, these...
Streaming is a technique used to transmit information over the network so that its issuing from the server, its communication along the network and its downloading and processing on the client overlapp, and moreover it must not be saved in the client memory. This technique is very effective for transmitting multimedia information (video) and is very suitable for mobile phones because there is no need...
Thanks to magnificent developments in the area of personal equipment, a single user easily can own multiple devices. The aspect of owning multiple devices can be easily found in ubiquitous computing environment; it is highly required to provide an effective way of managing one's resources. Therefore, we propose OPeN (overlaid personal network) to satisfy the requirement. OPeN is an overlay protocol...
Multimedia communication has become basic necessity of internet users. It has become more and more relevant in distributed environments. There are many protocols available in IP telecommunication world for signaling and control of Internet telephone calls. InterAsterisk eXchange protocol and RSW are considered to be major protocols for signaling and data. These two protocols provide competitive voice...
The development of an open architecture for multimedia data integration and visualization in template based distributed applications is a challenge for the scientific researches. Because of characteristics of multimedia data, their management and querying techniques are unlike than those of traditional data. We can increase the potential use of multimedia data across various applications by storing...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
