Today's data center servers are equipped with high speed and complex network adaptors, featuring an array of functions, e.g. hardware TX/RX queues, packet filters, rate limiters, etc. Recent work like IX, Arrakis, MultiStack has made us rekindle the user-level network stacks' innovation utilizing these commodity network adaptors. In this paper, we revisit the idea to move stacks' design from in-kernel...
The need to perform data analytics on exploding data volumes coupled with the rapidly changing workloads in cloud computing places great pressure on data-center servers. To improve hardware resource utilization across servers within a rack, we propose Direct Extension of On-chip Interconnects (DEOI), a high-performance and efficient architecture for remote resource access among server nodes. DEOI...
The growing internet network has led to the more complex design, management, and operational. The situation is getting harder because there are various protocol and hardware used in the networks. In order to overcome an easier network management and to obtain a better scalability, Software Defined Network (SDN) is used. SDN gives solution by applying an centralized network technology and separating...
Todays context frameworks provide solutions for context mechanisms for individual applications only: context aware working spaces, easier mobile development frameworks or higher-level context abstractions. RestContext solves this problem with a service logically separating context as a set of information that can characterize a situation from further context interpretation mechanisms. RestContext...
Multi-touch interfaces across a wide range of hardware platforms are becoming pervasive. This is due to the adoption of smart phones and tablets in both the consumer and corporate market place. This paper proposes a human-machine interface to interact with unmanned aerial systems based on the philosophy of multi-touch hardware-independent high-level interaction with multiple systems simultaneously...
Modern experiments in particle physics are based on advanced and sophisticated electronic systems. LLRF control system requires simultaneous data acquisition of multiple ADC channels and real time signal processing between pulses. Due to very high requirements related to reliability, availability, accessibility and efficiency development of software for such systems is very complex process. Additionally,...
To simplify computer management, various administration systems based on wired connections adopt advanced techniques to manage software configuration. Nevertheless, the strong relation between hardware and software makes for an individualism of that management, besides penalizing computational mobility and ubiquity. All these issues lead to degradation of scalability, flexibility and the facility...
Trico Electric Cooperative Inc (Trico) is a non-profit cooperative serving more than 38,000 rural customers in southern Arizona. Tirco is challenged with managing a distribution system with a wide geographical dispersion.
Remote Laboratories have traditionally been focused on specific solutions for specific problems. We can find a wide range of Remote Laboratories in the literature, assisting different types of subjects but commonly bound to a restricted set of requirements. Due to this, little attention has been paid on working on a maintainable, scalable, secure architecture that addresses the requirements of a wider...
The iSCSI protocol communicates over existing IP infrastructure, making it an intriguing storage alternative for cost-conscious HPC users. Two approaches have emerged for using iSCSI in an HPC context. With the first approach, I/O servers- also called data movers- access iSCSI storage at the block level and export it to the cluster nodes via a distributed file system. With the second approach, cluster...
SIP or session initiation protocol, and universal plug 'n play (UPnP) are application-layer control protocols. SIP is used for creating, modifying, and terminating sessions with one or more participants, through the Internet. UPnP is also a protocol developed by a vendor consortium to enable device networking and control. However, SIP lacks the necessary functionality to work with heterogeneous devices...
Using remotely located software or hardware resources for solving various technical problems is presently the main subject of the current emerging technologies such as utility computing, cloud computing, Grid computing and so on. This paper discusses a possible architectural solution and describes a platform built bearing in mind the requirements for solving mathematical-described problems, but potentially...
Innovation in gateways for data gathering sensor networks has lagged compared to advances in mote-class devices, leaving us with a limited set of options for deploying such systems. In this paper we outline the system design of a gateway that meets the hardware and software demands of data gathering networks and present a prototype implementation of this design using the popular Stargate platform...
The purpose of this article is to remove CPU from heavy services of protocol processing, and alleviate the bottlenecks of communication system to suit for the high speed network. Design a new architecture for TOE which includes TOE design, TOE data stream transfer, TOE performance test and TOE security, etc. By analysis and design with Linux specialties binding to functions of ML403 development version,...
