The migration of the Internet from classic computer communication to a platform for multimedia applications with real-time communication requires end-to-end improvements of the network-level service. The proposal known as Differentiated Services is a very promising approach for implementing quality of service in the Internet and is being discussed and developed. The challenge is to deliver end-...

Effective Big Data analytics pose several difficult challenges for modern data management architectures. One key such challenge arises from the naturally streaming nature of big data, which mandates efficient algorithms for querying and analyzing massive, continuous data streams (that is, data that is seen only once and in a fixed order) with limited memory and CPU-time resources. Such streams ...

Existing solutions for streaming multimedia in the Internet do not scale in terms of object size and number of supported streams. Using separate unicast streams, for example, will overload both network and servers. While caching is the standard technique for improving scalability, existing caching schemes do not support streaming media well. In this paper, we propose a complete solution for cac...

In this paper, we present a complete software control architecture for synchronizing multiple data streams generated from distributed media-storing database servers without the use of a global clock. Independent network connections are set up to remote workstations for multimedia presentations. Based on the document scenario and traffic predictions, stream delivery scheduling is performed in ei...

This paper addresses the issue of QoS management under the framework of Delivery Multimedia Integration Framework (DMIF) protocol stack for the support of MPEG4 multimedia streaming. In this paper, we describe how QoS was dealt in the implementation of a DMIF protocol stack over two different network technologies: IP networks with RSVP signaling and Asynchronous Transfer Mode (ATM) with Q.2931 ...

Multimedia applications require the transmission of real-time streams over a network. These streams often exhibit variable bandwidth requirements, and require high bandwidth and guarantees from the network. This creates problems when such streams are delivered over the Internet. To solve these problems, recently, a small set of differentiated services has been introduced. Among these, Premium S...

The article is devoted to solving an urgent scientific and technical problem. It consists of developing algorithm .This used for estimating the recommended buffer size requests transmitting data streams. So,this has been done in a flying self-organizing network .Therefore, it ensure geoecological monitoring resources agro-industrial complex. However, Studies have shown that required quality str...

Semiaquatic flies (Diptera, Nematocera) are an ecologically important and species rich group of insects within the boreal and arctic biomes. Community structure, species richness and abundance of semiaquatic flies were studied in three habitat types (aapa mires, springs and headwater streams), totaling 19 study sites, within the subalpine ecoregion of northern boreal Finland. Concordance of sem...

TCP and TCP-friendly rate control protocols, designed for unicast, do not take neighbor connections into account in P2P networks. In this paper, we study the topic of distributed and optimal rate control for scalable video streams in P2P streaming applications. First, we propose a fully distributed and TCPfriendly network analytical model for rate control and formulate an optimization problem t...

Current intrusion detection systems have a narrow scope. They target flow aggregates, reconstructed TCP streams, individual packets or application-level data fields, but no existing solution is capable of handling all of the above. Moreover, most systems that perform payload inspection on entire TCP streams are unable to handle gigabit link rates. We argue that network-based intrusion detection...
