Overlay architectures are the information theoretical playgrounds of the Internet. They provide significant gains in throughput by shifting complexity into the network nodes. A consequence is the requirement for smart routers between adjacent network segments. Since meanwhile audiovisual media allocate the major part of the Internet traffic, protocols as well as overlay structures have to serve Predictable...
The continuous growth of peer-to-peer networks has made them responsible for a considerable portion of the current Internet traffic. For this reason, improvements in P2P network resources usage are of central importance. One effective approach for addressing this issue is the deployment of locality algorithms, which allow the system to optimize the peers selection policy for different network situations...
Three requirements for leased-line service in a packet-transport system are determined such as service availability of 99.999%, bandwidth guarantee of 100%, and latency of 10 ms via 20 nodes. To meet these requirements, network architecture is proposed which includes the separation of control function and data-transmission function and shaping per flow at the entrance of a network. Nodes and gateways...
In the tactical Internet, inter-domain links consist mostly of unreliable and low bandwidth wireless links. To enable seamless routing across different Autonomous Systems (ASes), we propose an inter-domain Traffic Engineering (TE) scheme to reroute traffic when congestion occurs. There are two components for the TE scheme. First, a Traffic Splitting (TS) scheme is used for load balancing among parallel...
This paper presents an analysis of the network traffic generated by different interactive digital television applications using PLC as return channel on the context of SAMBA project. The analysis is conducted through the evaluation of performance of PLC compared to traditional IP network. The setup considers usual PLC network with presence of noise generated by electrical devices. It was evaluated...
The problem of providing quality of service (QoS) in the Internet stems from the original choice of a datagram packet switching service model for the Internet protocol (IP). Since, in principle, each packet can take any path to the destination, it is impossible to provide any absolute guarantees about service. This paper presents a scheme using traffic engineering techniques and implements policy...
High packet switching performance and the potential scalability to a large number of input/output ports, under the admissible traffic assumption, have made Birkhoff-von Neumann load-balanced switch one of the most attractive and promising switch architecture. The focus of this study is on the construction of large number of input/output ports load-balanced switch with very high transmission rate,...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
