Modern vehicles employ a large amount of distributed computation and require the underlying communication scheme to provide high bandwidth and low latency. Existing communication protocols like Controller Area Network (CAN) and FlexRay do not provide the required bandwidth, paving the way for adoption of Ethernet as the next generation network backbone for in-vehicle systems. Ethernet would co-exist...
HPCG and Graph500 can be regarded as the two most relevant benchmarks for high-performance computing systems. Existing supercomputer designs, however, tend to focus on floating-point peak performance, a metric less relevant for these two benchmarks, leaving resources underutilized, and resulting in little performance improvements, for these benchmarks, over time. In this work, we analyze the implementation...
Higher integration lowers total cost of ownership (TCO) in the data center by reducing equipment cost and lowering energy consumption. However, higher integration also makes it difficult to achieve guaranteed quality of service (QoS) for shared resources. Unlike many other resources, memory bandwidth cannot be finely controlled by software in existing systems. As a result, many systems running critical,...
Medical Big Data (MBD) is the most critical form of information. MBD over a colossal Wireless Network (WN) is a sophisticated area of concern. Every day WN is becoming more dense and complicated. The MBD can be saved to wireless network after applying suitable Wavelet Compression. The quality of MBD is the most important factor; which means efficient and reliable transmission. Wavelet Compression...
Reliable and secure wireless communications is fundamental to connectivity between smarter gadgets and people. This is much more true in defence applications with its unique requirements and challenges. Broadly the data link requirements in defence applications are seen under two categories. One, robust fool-proof zero downtime data links for telemetry, command and control. Second, broad band data...
NAND flash is seeing increasing adoption in the data center because of its orders of magnitude lower latency and higher bandwidth compared to hard disks. However, flash performance is often degraded by (i) inefficient storage I/O stack that hides flash characteristics under Flash Translation Layer (FTL), and (ii) long latency network protocols for distributed storage. In this paper, we propose a minimalistic...
With the recent rise in cloud computing, applications are routinely accessing and interacting with data on remote resources. As data sizes become increasingly large, often combined with their locations being far from the applications, the well known impact of lower TCP throughput over large delay-bandwidth product paths becomes more significant to these applications. While myriads of solutions exist...
Network Functions Virtualization (NFV) is a recent networking trend gaining a lot of attention from telecom operators and vendors. It promises to virtualize entire classes of network node functions within a data-center and to deliver network services in the form of Virtualized Network Function (VNF) service chains using commercial off-the-shelf hardware and IT virtualization technologies. However,...
Virtually all ATE systems employ a switching subsystem in order to route test system resources to multiple test points on the UUT. The challenge for any switching subsystem is multi-dimensional and involves many considerations / trade-offs including footprint, performance, flexibility, maintainability, and reliability. Additionally, if the application needs to address legacy test needs, there can...
A large fraction of MapReduce execution time is spent processing the Map phase, and a large fraction of Map phase execution time is spent sorting the intermediate key-value pairs generated by the Map function. Sorting accelerators can achieve high performance and low power because they lack the overheads of sorting implementations on general purpose hardware, such as instruction fetch and decode....
This Paper presents a telco's perspectives and experiences to design and implement open and flexible architecture for Transport SDN (T-SDN). We believe that this could be realized by adopting open source based SDN controllers because they already have widely accepted and referenced architecture with a rich ecosystem. Moreover, we could have further benefits from open source such as reducing time to...
Multi-tenant clouds with resource virtualization offer elasticity of resources and elimination of initial cluster setup cost and time for applications. However, poor network performance, performance variation and noisy neighbors are some of the challenges for execution of high performance applications on public clouds. Utilizing these virtualized resources for scientific applications, which have complex...
The service delivery has evolved during the last years. The introduction of Software Defined Networking (SDN) and Network Functions Virtualisation (NFV) has driven network programmability to foster the innovation in the provisioning of new services. The orchestration and dynamic deployment of resources for service delivery are relevant topics covered by this demonstration.
Software defined networks (SDN) are an emerging technology that is being increasingly adopted by various network operators. These technologies provide new services and powerful analytics that help to transform the network and unfasten its intelligence to serve today's business demands. This paper briefs about the need for change in the current networking technology and explores the role of Open Flow...
Recently there has been a new emerging trend in integrating Information Centric Networking (ICN) and Software Defined Networking (SDN) together in the future internet research area. Software defined information centric networking (SD-ICN) may face more serious scalability problem in control plane compared with traditional SDN environment due to new features about in-network cache and content-based...
In Intel's CPU releasing model, the new Ivy Bridge is a “TICK” that follows Sandy Bridge's (“TOCK”) microarchitecture principles, however, after undergoing a die shrink it is manufactured at 22nm. It also incorporates new micro-architectural upgrades. In this paper we shall evaluate the performance of a 16 bi-socket node cluster based on this 3rd generation Intel Xeon Processor E5-2697v2 meant for...
In the years between now and 2020, we should expect continued exponential data growth [15][16]. A number of ongoing advances in storage: the transition to solid-state drives (SSDs), the scaling of NAND flash capacity, and advanced silicon packaging techniques will dramatically increase the capacity of storage subsystems over the same timeframe. This will significantly reduce the ratio of storage bandwidth...
The development of methodologies to manage and orchestrate virtualised resources and network functions is a fundamental enabler for optimally utilising physical ICT infrastructures. Algorithms for optimal location (embedding) of network functions, IT and CT resources, services and corresponding states, especially at the network edge, will enable new business models and provide a key competitive advantage...
With the growing adoption of Software Defined Networking (SDN), there is a compelling need for SDN emulators that facilitate experimenting with new SDN-based technologies. Unfortunately, Mininet [1], the de facto standard emulator for software defined networks, fails to scale with network size and traffic volume. The aim of this paper is to fill the void in this space by presenting a low cost and...
