SDN is considered to be a promising way re-architect the Internet. However, Internet managed by owners of different administrative domains, so centralized control model must extended account for inter-domain traffic. Thus, this article proposes WE-Bridge mechanism enable domains peer and cooperate. Based on WE-Bridge, we further designed two innovative routing applications as use cases. To verify our design, implemented cases building an international testbed which together with cases, are...

In current practice, product developers with customized small batch production needs come across the problem of finding capable and flexible manufacturers, whereas manufacturers face underutilization due to inconsistent demand. This paper presents a Production as Service (PaaS) framework connect users (consumers or developers) who have manufacturing existing underutilized resources. PaaS is cloud-based, centralized based on service-oriented architecture that abstracts steps individual...

Safety violations in programmable logic controllers (PLCs), caused either by faults or attacks, have recently garnered significant attention. However, prior efforts at PLC code vetting suffer from many drawbacks. Static analyses and verification cause false positives cannot reveal specific runtime contexts. Dynamic symbolic execution, on the other hand, fail due to their inability handle real-world programs that are event-driven timing sensitive. In this paper, we propose VetPLC, a temporal...

We propose a novel cellular core network architecture, SoftBox, combining software-defined networking and function virtualization to achieve greater flexibility, efficiency, scalability compared today's core. Aligned with 5G use cases, SoftBox enables the creation of customized, low latency, signaling-efficient services on per user equipment (UE) basis. consolidates policies needed for processing each UE's data signaling traffic into light-weight, in-network, per-UE agent. design number...

Open ports are typically used by server software to serve remote clients, and the usage historically leads exploitation due insufficient protection. Smartphone operating systems inherit open port support, but since they significantly different from traditional machines in performance availability guarantees, little is known about how smartphone applications use what security implications are. In this paper, we perform first systematic study of on mobile platform their implications. To...

Abstract The staining of nucleic acids with fluorescent dyes is one the most fundamental technologies in relevant areas science. For reliable and quantitative analysis, efficiency should not be very dependent on sequences specimens. However, this assumption has necessarily been confirmed by experimental results, especially ssDNA (and RNA). In study, we found that both SYBR Green II Gold did stain either homopyrimidines or composed only adenine (A) cytosine (C). these two emit strong...

Due to the relatively large uncertainty and high cost of power generation multi-energy grid system, optimization scheduling with these problems as object solution needs take more targeted measures. The purpose this paper was study a better system scheme, an improved mixed integer linear algorithm proposed. And based on algorithm, smart stadium optimized, at same time, common particle swarm used optimize compare effects. experimental results showed that total monthly supply optimized 2061.2...

The emerging 5G networks and applications require network traffic to be buffered at different points in a wide area with policies based on user mobility, usage patterns, device application types. Existing Software Defined Network (SDN) solutions fail provide sufficient decoupling between the data-plane control-plane enable efficient control of where, when, how flow is without causing excessive traffic. Alternative approaches either cater application-specific use cases or follow completely...

We present a Production as Service (PaaS) framework that connects users (product developers) who have small batch production needs, with existing manufacturing facilities underutilized resources. PaaS is web-based based on the service oriented architecture (SOA) design breaks down of product into several steps, or services, to incorporate various manufacturers available capability in fulfilling request. Preservation intellectual property (IP) major concern SOA systems. Presented work aims...

While advances in technology have greatly improved the process of mass production, producing small batches or one-offs an efficient manner has remained challenging for manufacturing industry. Additionally, both large and companies, there are often available resources that sit idle between projects. In this paper we present a Production as Service framework providing options to designers new products based on resources. The designed aims bridge gap theoretical work been done Oriented...

Abstract As real-world systems become more complex and connected, the industrial sector requires engineers who can solve problems across multiple disciplines work with people various educational backgrounds. This is particularly apparent in manufacturing industry, as integration of new system technology knowledge a diverse set fields, such physics, computer science, engineering, to name few. To properly educate next workforce manufacturing, engineering education needs incorporate...

Existing SDN controllers commonly adopt an event-driven model that minimizes southbound communication and control-plane overhead. This satisfies most existing applications' goals to maximize data plane performance while still being able programmatically control with a decent level of visibility. However, as network composition becomes more heterogeneous NFV IoT, such can be insufficient for future applications rely on analysis intelligent decision making.

<sc>Abstract.</sc> This study aimed to develop an environmental monitoring and control system for pig nurseries by using Internet of Things framework. In the system, data, namely temperature, humidity, ammonia content, wind speed, were collected a microcontroller connected with sensors; data transmitted remote server through WiFi. The enabled users monitor their at any time mobile or web applications. At site research farm, programmable logic controller (PLC) was used collect from sensors,...

Traffic migration is a common procedure performed by operators during planned maintenance and unexpected incidents to prevent/reduce service disruptions. However, current practices of traffic often couple operators' intentions (e.g. device upgrades) with network setups load-balancers), resulting in poor re-usability substantial operational complexities. Our study 205 Methods Procedure (MOPs) from major U.S. carrier suggests that generalizing unified model feasible. Such generalization along...

The paper focuses on how land property affects people’s choices of migration from rural areas to urban areas. Based the empirical analysis, conclusion can be achieved that is improved under market mechanism. Therefore, if country wants stimulate human areas, mechanism should built and protected.
