26 Aug 2008TL;DR: In this paper, the authors describe techniques for adaptively applying network acceleration services within an intermediate network device, which comprises a classifier module that receives network traffic and a servicing engine.
Abstract: In general, techniques are described for adaptively applying network acceleration services within an intermediate network device. In particular, the intermediate network device comprises a classifier module that receives network traffic and a servicing engine. The servicing engine applies the network acceleration services to the network traffic in accordance with a service configuration and monitors the application of network acceleration services to determine whether the application of each of the network acceleration services improves the efficiency with which the network traffic is serviced. The servicing engine then dynamically adapts the service configuration to alter the application of the network acceleration services based on the determination. Thereafter, the servicing engine applies the network acceleration services to the network traffic in accordance with the dynamically adapted service configuration to more efficiently service the network traffic.

TL;DR: Delay tolerant calls access slack capacity in a telecommunications network under variable pricing controlled by the network so as to permit the network to pick up or stimulate background traffic loads as and when desired to gain revenue from background idle capacity as discussed by the authors.

TL;DR: In this paper, the authors make contributions to the design, implementation, and performance measurement of distributed interactive simulation systems and describe how the CORBA Event Service can be implemented to support key QoS features.
Abstract: Advanced distributed interactive simulations have stringent quality of service (QoS) requirements for throughput, latency, and scalability, as well as requirements for a flexible communication infrastructure to reduce software lifecycle costs. The CORBA Event Service provides a flexible model for asynchronous communication among distributed and collocated objects. However, the standard CORBA Event Service specification lacks important features and QoS optimizations required by distributed interactive simulation systems. This paper makes five contributions to the design, implementation, and performance measurement of distributed interactive simulation systems. First, it describes how the CORBA Event Service can be implemented to support key QoS features. Second, it illustrates how to extend the CORBA Event Service so that it is better suited for distributed interactive simulations, such as the next-generation Run Time Infrastructure (RTI-NG) implementation for the Defense Modeling and Simulation Organization’s (DMSO) High Level Architecture (HLA). Third, it describes how to develop efficient event dispatching and scheduling mechanisms that can sustain high throughput. Fourth, it describes how to use multicast protocols to reduce network traffic transparently and to improve system scalability. Finally, it illustrates how an Event Service framework can be strategized to support configurations that facilitate high throughput, predictable bounded latency, or some combination of each.

TL;DR: The results demonstrate that real- time modification of links costs produces statistically significant improvements in traffic distribution metrics, which indicates that SDN enables the use of real-time modification of link cost functions as an effective technique for implementing traffic load balancing for multicast traffic.
Abstract: In this paper we propose an approach for applying traffic load balancing to multicast traffic through real-time link cost modification in a software defined network (SDN) controller. We present an SDN controller architecture supporting traffic monitoring, group management, and multicast traffic routing. An implemented prototype is described, and this prototype is used to implement shortest path multicast routing techniques which make use of the real-time state of traffic flows in the network. This prototype is evaluated through experimentation in Mininet emulated wide area networks. Evaluation is presented in terms of resulting network performance metrics focusing on the distribution of traffic flows. Our results demonstrate that real-time modification of links costs produces statistically significant improvements in traffic distribution metrics, with an average improvement of up to 52.8% in traffic concentration relative to shortest-path routing. This indicates that SDN enables the use of real-time modification of link cost functions as an effective technique for implementing traffic load balancing for multicast traffic.
