The predicted prevalence of both Internet of Things (IoT) based devices and the concept of Software Defined Networking (SDN) as a new paradigm in networking, means that consideration is required for how they will interact. Current SDN implementations operate on the principle that on receiving an unrecognised packet, a switch will query a centralised(More)
With near exponential growth predicted in the number of Internet of Things (IoT) based devices within networked systems there is need of a means of providing their flexible and secure integration. Software Defined Networking (SDN) is a concept that allows for the centralised control and configuration of network devices, and also provides opportunities for(More)
As recognition grows within industry for the advantages that can be gained through the exploitation of large-scale dynamic systems, a need emerges for dependable performance. Future systems are being developed with a requirement to support mission critical and safety critical applications. These levels of criticality require predictable performance and as(More)
One of the major challenges of computer system design is the management and conservation of energy while satisfying QoS requirements. This paper considers two methods for reducing energy consumption of the CPU and network interface card by using Dynamic Voltage Scaling (DVS) and Transmission Power Control (TPC) techniques. Moreover, energy fairness is(More)
This paper proposes a dynamic arrival process to represent a typical TCP source in Queueing theory performance modeling. This process utilises a novel time-dependant statistical calculation approach, which modifies and extends the traditional method of modeling and calculating Geo/Geo/1/J (discrete-time M/M/1/J) queues. The main contributions of this paper(More)
Software Defined Networking (SDN) is an emerging paradigm that changes the way networks are managed by separating the control plane from data plane and making networks programmable. The separation brings about flexibility, automation, orchestration and offers savings in both capital and operational expenditure. Despite all the advantages offered by SDN it(More)
We present three case studies of organizations using a data science competition to answer a pressing question. The first is in education where a nonprofit that creates smart school budgets wanted to automatically tag budget line items. The second is in public health, where a low-cost, nonprofit womens’ health care provider wanted to understand the effect of(More)
The broadcasting industry has recently begun to adopt statistical multiplexing based network platform in their workflow to support professional live audio/video (AV) transmission instead of the Time Division Multiplexing (TDM) based system. These audio-over-packet switched systems require a carefully designed and managed network to ensure key quality(More)
