System Analysis for Satellite Networks with Free-Space Optical Links
… performances for free-space optical satellite networks (FSOSNs), including phasing parameter, optical satellite link budget, tradeoff between network latency and satellite transmission power, and network latency minimization based on satellite transmission power constraints. We investigate the …

A behavioural analysis of computer game playing competence, experience and related physiological processes
… In the literature review presented in Chapter 1, Network Latency and 'game challenge' were identied as two important variables affecting participants' enjoyment of on-line games. The experiments presented in Chapter 2 define 'game challenge' in terms of levels of derived relational responding, and …

Coflow scheduling in data center networks
… a multi-stage abstraction for the data center network enables development of algorithms that reduce the network latency for certain traffic patterns. In this context, I compare the capabilities of the multi-stage network with the cross-bar switch via simulations and theoretical calculations. A …

Latent networks: Ties, structures, and effects within an anonymous community
… sought to understand the dynamics of latent network structures – what they look like in action, how the social forces within function, and how ties within such a structure may develop. Relying on initial theory developed by Caroline Haythornthwaite (2005), incorporates empirical observations …

The swept rule for breaking the latency barrier in time-advancing PDEs
… The method is motivated by our observation that network latency, not bandwidth or computing power, often limits how fast PDEs can be solved in parallel. The method is called the swept rule of space-time domain decomposition. Compared to conventional, space-only domain decomposition, it …

Computing network coordinates in the presence of Byzantine faults
Network coordinate systems allow for efficient construction of large-scale distributed systems on the Internet. Coordinates provide locality information in a compact way, without requiring each node to contact every potential neighbor; distances between two nodes' coordinates represent estimates of …

Dynamic Shared State Maintenance In Distributed Virtual Environments
Advances in computer networks and rendering systems facilitate the creation of distributed collaborative environments in which the distribution of information at remote locations allows efficient communication. Particularly challenging are distributed interactive Virtual Environments (VE) that …

Exploiting on-chip memory concurrency in 3d manycore architectures
… of the memory system. First, we observe that 2D network latency and inefficient parallelism management in the current 3D designs are the main bottlenecks to fully exploit the potentials of 3D. To that end, we propose an extremely low-latency, low-power, high-radix router and present its various …

The Effects of Low Earth Orbit Satellite Constellation Altitude and Inclination on Simulated Non-Terrestrial Network Performance
… of satellite communications, non-terrestrial networks (NTNs) have varied in scale and architecture. Satellite orbital elements have been a key feature of the ongoing development and design of modern constellations. Orbital altitude and inclination have impacted the types of service and extent …

Bringing Fault Tolerance to Hardware Managers in PESNet
… and dynamic reconfiguration of the network. Many ideas for supporting fault tolerance have been discussed in previous work and the hardware for PEBB-based systems was designed so support fault tolerance. However, in spite of the capabilities of the hardware, fault tolerance is not …
