A modelling and networking architecture for distributed virtual environments with multiple servers.
… a single-person running on a single computer, to multiple-people running on several computers connected through a network. When VEs are distributed on multiple computers across a network, we call this a Distributed Virtual Environment (DVE). Virtual Environments can benefit greatly from …

A Distributed Software Framework for the Virginia Tech Ground Station
… tasks and process at a ground station with multiple servers and controllers, a specialized actor framework was written in Python for ease of use. Actors have the ability to send messages to one another over a network, and they maintain their own memory in order to avoid synchronization …

Staffing queueing systems with cyclical demand and unreliable servers
Unplanned staff absences, referring to scheduled servers being unavailable, pose significant challenges in sectors like healthcare, airlines, and correctional facilities, leading to under-staffing and management reliability issues. This thesis investigates the effectiveness of the Stationary …

A distributed metadata-private messaging system
… being able to scale its work efficiently across multiple servers. Stadium uses the same differential privacy definition for metadata privacy as Vuvuzela, the currently highest-scale system. However, providing privacy in Stadium is significantly more challenging because distributing users' traffic …

Fairness for resource allocation in cloud computing.
Resource allocation with fairness, considering multiple types of resources has become a substantial concern in state-of-the-art computing systems. Accordingly, the rapid growth of cloud computing has highlighted the importance of resource management as a complicated and NP-hard problem. Unlike …

Analysis of congested clients' flows in banking systems: A case study of Standard Bank Namibia
… was M/M/s which involved a single line with multiple servers in the system.Customer arrivals were described by a poison distribution and service times by exponential distribution. Descriptive analysis was used to describe the parameters of the queuing system, a radar chart to display the …

Decomposition of general queueing network models. An investigation into the implementation of hierarchical decomposition schemes of general closed queueing network models using the principle of minimum relative entropy subject to fully decomposable constraints.
… general queueing networks with single and multiple servers and favourable comparisons against exact solutions and other approximations are made.

Rich Cloud-based Web Applications with Cloudbrowser 2.0
… CloudBrowser 2.0 can be deployed on a cluster of servers as well as a single multi-core server. It distributes the virtual browsers to multiple processes and dispatches client requests to the associated virtual browsers. CloudBrowser 2.0 also refines the CloudBrowser application deployment model …

Fault-tolerant distributed transactions for partitioned OLTP databases
… partitioning data across a cluster of commodity servers in a data center. Combining multiple servers together allows systems built with Dtxn to be cost effective, highly available, scalable, and fault-tolerant. Dtxn provides three novel features. First, it provides reusable infrastructure for …

Measuring the impact of site configurations on site fingerprinting over the web and Tor
… and hosting sites from both single and multiple servers in order to observe the effect of each of these changes on fingerprinting accuracy. In order to collect traces from sites that reflect our experimental changes, we create models of real-world sites and onion services that capture …

A next-generation apparatus for lithium optical lattice experiments
… for sequence design and a set of output hardware servers. Output hardware servers are designed to use standard National Instruments output cards, but the client-server nature allows this to be extended to other output hardware. Output sequences running on multiple servers and output cards can be …

New directions for remote data integrity checking of cloud storage
… in which the data is stored redundantly at multiple servers. The client can use RDC to check each server and, upon having detected a corrupted server, it can repair this server by retrieving data from healthy servers, so that the reliability level can be maintained. Previously, RDC has been …

Online scheduling algorithms for average flow time and its variants
… that are found in a client-server setting where multiple clients and one server (or multiple servers) are the participating entities. Clients send their requests to the server(s) over time, and the server needs to satisfy the requests using its resources. This setting is prevalent in many …

Metrics, fundamental trade-offs and control policies for delay-sensitive applications in volatile environments
… Second, we generalize the results to the case of multiple servers or peers streaming to a single receiver. Random linear network coding allows us to simplify the packet selection strategies and alleviate issues such as duplicate packet reception. We show that the multi-server streaming problem …
