In this paper, we consider the energy-efficient coordination of a set of appliances in a smart-building. We introduce a theoretical formulation of the coordination problem and an Integer Linear Programming model for its resolution. Our formalization is complemented by an analysis of the properties and limits of the model. We also define a practical smart-building setting in which our formalization...
The deployment of modular virtual network functions (VNFs) in software defined infrastructures (SDI) enables cloud and network providers to deploy integrated network services across different resource domains. It leads to a large interleaving between network configuration through software defined network controllers and VNF deployment within this network. Most of the configuration management tools...
Multipath TCP (MPTCP) has gained great attention by the researchers and network application developers due to its features providing better bandwidth utilization and higher reliability recently. Utilizing MPTCP in the datacenters provides performance gain to the applications. If the underlying network has Software Defined Networking (SDN) architecture, the routing of the MPTCP subflows can be specialized...
This study investigates the effect of image rescaling and format changing hosted in a RESTful API architecture considering transfer time as a critical factor to apply lane detection on a external server. We employ Probabilistic Hough Transform to perform the detection because it is invariant to pixel position and robust to noise. Before being trasmitted to the external server, images are rescaled...
In recent times, mobile broadband networks are focused on bringing different capabilities to the edge of the mobile network. Mobile Edge Computing (MEC) addresses this issue by placing the compute and storage resources closer to the Radio Access Network (RAN), with an aim to reduce end-to-end latency, ensure better service delivery, and offer improved user experience. In this work, we propose SDEC...
MEC or Multi-Access Edge Computing is a network service delivery architecture that enables cloud computing capabilities at the edge of the access network. Realisation of the MEC vision is challenging with current network technologies: service discovery and routing, secure network slicing and distributed mobility management require complex capabilities in the network. This demo features an OMEC use...
Recently, mobile broadband networks are focused on bringing additional capabilities to the network edge. For instance, Mobile Edge Computing (MEC) brings storage and processing capabilities closer to the mobile user i.e., at the radio access network, in order to deploy services with minimum delay. In this paper, we propose a resource constrained cloud-enabled small cell that includes a MEC server...
Virtualized network function (VNF) service chaining in optical datacenter networks (DCN) is a more complex problem than that in packet-switched networks, as it introduces additional constraints related to the optical network. For example, in an optical DCN one needs to make sure that optical network resources are efficiently utilized, which requires multiplexing of several VNF chains to fill the optical...
Mobile medical applications are increasingly being used by patients and consumers. However, due to their complexity, these applications are normally only accessible to smartphone users. People using low-end cellphones cannot benefit from this new technology. The goal of this paper is to expand health service platform to lower-end cellphones, so that people in underdeveloped regions can benefit from...
Series-stacked server power delivery architectures have been proposed recently that can achieve much higher energy efficiency than conventional power delivery architectures. When servers are connected in series, differential power processing (DPP) converters can be used to regulate the server voltages when the servers are consuming different amount of currents. Server-to-bus DPP architecture has unique...
This paper briefly introduces the Command Query Responsibility Segregation (CQRS) and discusses the performance of the architecture. The pattern is separated from the business by modifying the behavior of modifying (adding, deleting, modifying the system state) and querying (without modifying the system state), making the logic clearer and easier to target different parts Optimization, and finally...
With the development of Internet technology, Automatic Train Supervision (ATS) simulation system with traditional C/S architecture is more and more inconvenience for its incompatibility with internet and the high cost of maintenance and development. It is more practical to use B/S structure. However, computer interlocking(CI) system with ATC system using UDP protocol is not compatible with remote...
DC distribution is emerging as a solution for data centers, however the optimal system architectures have not been established in the industry. This paper first reviews the most recent studies, products and activities of DC distribution in data centers. A hybrid AC and DC distribution architecture is introduced by using both 415V AC and 380V DC together to achieve the data center reliability requirements...
In the 5G era, radio IP capacity is expected to reach 20 Gbit/s per sector, and ultra-large content traffic will travel across the faster wireless/wireline access network and packet core network. Also massive and mission-critical IoT is the main differentiator of 5G services. These types of real-time and large-bandwidth consuming services require radio latency of less than 1ms, and end-to-end latency...
Recently, a micro-service architecture has been adopted to an edge device in smart factory due to its maintainability and scalability. In the architecture, all services are generally implemented as Docker containers and deployed by Docker APIs which might be harsh to a factory operator. In this paper, we propose an easy-to-use web-based service deployment method for containerized service to in-factory...
To integrate different types of devices around Erhai, China, a three layer architecture is introduced. Edge computing nodes are inserted between the server system and the end devices. A metadata model is proposed to unify the representation of devices, measurement and the interactive message between the web services and devices. The edge nodes firstly function as translator between the web services...
Cyber-Physical Systems (CPSs) may fail during runtime on supporting decision making if they are not capable of detecting and correcting their own failures. Thus, it has been proposed that CPSs should be self-aware, context-aware and goal-aware. In this paper we present preliminary results about how an architecture built over the Extensible Messaging and Presence Protocol (XMPP) may implement a distributed...
More and more cyber-physical systems and the internet of things push for a multitude of devices and systems, which need to work together to provide the services as required by the users. Nevertheless, the speed of development and the heterogeneity of devices introduces considerable challenges in the development of such systems. This paper describes a solution being implemented in the setting of a...
Virtual Content Delivery Network (vCDN) orchestration is necessary to optimize the use of resources and improve the performance of the overall SDN/NFV-based CDN function in terms of network operator cost reduction and high streaming quality. It requires intelligent and enticed joint SDN/NFV orchestration algorithm due to the evident huge amount of traffic to be delivered to end customers of the network...
We present the MASSE architecture, a YARA-based open source client-server malware detection platform. MASSE includes highly effective automated syntactic malware detection rule generation for the clients based on a server-side modular malware detection system. Multiple techniques are used to make MASSE effective at detecting malware while keeping it from disrupting users and hindering reverse-engineering...
