Traffic- and Thermal-aware Adaptive Beltway Routing for three dimensional Network-on-Chip systems

Abstract: The distribution of traffic and temperature in a high-performance three dimensional Network-on-Chip (3D NoC) system become more unbalanced because of chip stacking and applied minimal routing algorithms. To regulate the temperature under a certain thermal limit, the overheated nodes are usually throttled by run-time thermal management (RTM). Therefore, the network topology becomes a Non-Stationary Irregular Mesh (NSI-Mesh) and leads to heavy traffic congestion around the throttled nodes. Because of the traffic imbalance in the network, the system performance degrades sharply as temperature rises. In this paper, a Traffic- and Thermal-aware Adaptive Beltway Routing (TTABR) is proposed to balance both the distribution of the traffic and temperature in the network. The proposed TTABR can be applied to NSI-Mesh and regular mesh. The experimental results show that the proposed TTABR can achieve more balanced both traffic and temperature distribution, and the network throughput is improved by around 3.4~113% with less than 18% area overhead.

Performance analysis of a method for high level prevention of traffic analysis

Abstract: One of the stated goals of communications security is the prevention of traffic analysis. A model to prevent traffic analysis by rerouting and padding the traffic matrix, so that the apparent final traffic matrix is neutral, is analyzed. The objective of this analysis is to justify the claims of the model and to show that rerouting of traffic via intermediate nodes with minimum padding is indeed a cost effective method to prevent traffic analysis. Simulation results supporting the above claim are also presented. The requirement that final traffic matrix be neutral may be too restrictive in some cases, and various modifications to the model are suggested, while still ensuring prevention of traffic analysis. Prevention of traffic analysis in real time is addressed briefly. >

Providing reports to mobile network operators based on optimisiciency of wireless network traffic and/or battery consumption reduction

Abstract: Mobile network reporting and usage analytics system and method includes generating a report for a mobile network operator, which may be implemented on a system, including tracking optimisation efficiency for traffic in a wireless network, generating the report to be provided to the network operator based on the optimization efficiency and performing functions related to traffic optimisation and management in the wireless network effectuating in traffic alleviation in the wireless network measured by the optimisation frequency. The optimisation efficiency can include efficiency information associated with different mobile applications and user-related information in a wireless network. A client side proxy on the mobile device tracks optimization efficiency for traffic, and also determines battery consumption data and performs functions related to battery consumption reduction. A server side proxy determines optimization efficiency for wireless network traffic and tracks user-related information, for generating reports to network operators.

Method and a system for simulating the behavior of a network and providing on-demand dimensioning

Abstract: The invention simulates the behavior of a network including a set of network elements by introducing into the network a parametered flow intended to simulate a constraint on a network element. The flow can model the variation in time of the traffic intensity in the network in relation to the or each element to which a flow is addressed in the context of the simulation, and can feature a modulation on a macroscopic timescale and stochastic fluctuations on a microscopic scale. The invention further provides on-demand dimensioning of a network by uprating, during the simulation, the levels of performance of elements that have manifested a weakness in relation the flow at the time of the simulation. The field of application targets any type of network: circuit mode or packet mode data, electronic or optical networks, and even networks for transporting material or nonmaterial commodities.

Joint measurement- and traffic descriptor-based admission control at real-time traffic aggregation points

Abstract: The primary role of admission control is to decide on the amount of traffic accepted into the network so that users conforming to their established traffic contracts achieve predefined performance objectives, e.g. bounded packet loss probability, end-to-end delay. We consider Diffserv networks able to support real-time traffic and we propose a novel framework for admission control that involves both traffic descriptor and measurement-based techniques and we compare its performance with existing approaches. Our simulation results show that the performance of our approach is rather insensitive to variations of the traffic sources. Even when the provided traffic descriptors are as simple as a single value denoting the required peak rate, the proposed scheme achieves satisfactory performance.
