Monitoring the activity of equipment in datacenters is often a key element in designing large scale network and IT infrastructure. The information collected by direct parameter observations (such as total network traffic, CPU usage, etc.) represents a first step in the overall system performance optimization. A second one is denoted by data analytics and decision making strategies based on the values...
Adaptive content streaming is frequently used as an efficient and cheap solution to achieve a good quality for media streaming, in systems having light Over-the-Top architectures. The streaming system developed here makes an initial optimized server selection based on multi-criteria algorithms and then in-session media adaptation. The focus of this paper is on performance analysis (based on real-life...
This paper presents an analysis of the performance of resource management in a distributed, multi-domain, multimedia oriented network architecture, which establishes end-to-end network pipes over a virtual network of content-aware domains. Bandwidth allocation and routing is done using a QoS optimizing algorithm with the network topology given as input, in a distributed, on-demand, manner by the other...
This paper proposes a solution for a wireless mesh network based on WiMAX mesh nodes equipped with Smart Antennas. A WiMAX mesh node is emulated by interconnecting via Ethernet link a Base Station and a Subscriber Station. To avoid interference between these two nodes, they are configured to operate on different frequency bands. This solution can be used to build wireless backhaul networks for rural...
For Future Internet multimedia distribution with different levels of guarantees a transport solution may consist in creation of parallel multi-domain Virtual Content Aware Networks (VCAN) constructed as overlays over IP networks. How to map the VCANs topologies and requested capacities on real core network domain resources both inter and intra-domain while optimizing the resource usage is still an...
Next generation wireless communication will integrate the heterogeneous wireless technologies in order to provide better services, with improved quality, higher coverage, and seamless access to the system resources. Providing support for the connection transfer between different access technologies — vertical handover — together with radio resources management for the integrated networks are the major...
