According to the characteristics of the information resources in modern acquisition, such as heterogeneous, distributed, loosely coupled, the problems and deficiencies of workflow technology and products were analyzed. Dynamic service grouping strategies based on SOA was proposed and was proved in theory. In addition, the workflow architecture based on SOA was built and the workflow engine of simulation-based acquisition (SBA) was designed. Therefore, the legacy code can be wrapped and the service can be grouped dynamically from the dynamic generic service factory. Grouping strategy was proved according to the SPOT satellite image application which was part of the SBA toolbox on grid. Experimental results show that: services grouping of a workflow can reduce the total overhead induced by the submission, scheduling, queuing and data transfer time. On a production grid infrastructure, the optimization proposed introduces a significant speed-up when compared to a traditional execution. The range is from 1.21 to 2.97.

Over The Top

Recently, mobile operators all over the world are facing big challenges on the decreasing of the revenues from its traditional killer-applications like SMS/MMS and even voice services. The challenges come from a new trend of services called OTT (Over The Top). These OTT services provide the mobile users with flexible, convenient and more importantly free means to do their daily multimedia communication needs and seamlessly without any border so that operators couldn’t be just simply block it, but in opposite, need to find solutions to compete against it. Because of that, nowadays, more and more operators choose to deploy the standard RCS (Rich Communication Suite). RCS is a set of rich features communication services developed on top of IMS framework. Although there have been tremendous efforts to develop the architecture and protocols for IMS, which is a key technology of the NGN, it is far from being widely deployed. There are many reasons for that unpopularity (of IMS commercial deployment), namely, the lacking of clear business model for IMS-based services, no big difference between IMS-based services and SOA (Service Oriented Architecture) services, lack of the true demands for features that IMS based services have, etc... However, one of the most important reason that till now not many researchers have pointed out and addressed it, is about the OSS (Operation and Support Subsystem) functions. The lacking of OSS clearly defined functions and interfaces make the difficulties for operators and even equipment manufacturers to collect the pay back for any big scale IMS deployment for their networks. This paper presents our proven that IMS can provide the killer applications with blending features like mash-up and readily equipped with the intelligent charging and policy control functions. That may partly help to speed up the deployment process of IMS in real networking environment.

Network Management Architecture

Traditional NM (Network Management) techniques can not be applied on WSN (Wireless Sensor Network) due to its features of low computing ability, tiny memory space, and limited energy. A new NMA (Network Management Architecture) for WSN is needed. In this paper, we design a loosely coupled NMA of WSN based on SOA (Service-Oriented Architecture), and have well defined NM interfaces. Finally, we develop a SOA platform for WSN operations according to the NMA. Based on SOA platform, users can compose and use various NM Web Services by internet depending on their requirements. Heavy tasks which need a great deal of computing resources and storage are executed on the SOA platform. Thus, energy consumption and node computation can be decreased. Moreover, external applications use Web Services to integrate SOA platform for WSN. It lowers the difficulty in integrating different sensor platforms and heterogeneous devices.

INTISARILayanan Pesan Singkat atau Short Message Services(SMS) merupakan salah satu layanan jaringan telepon seluler yang digunakan untuk mengirimkan pesan pendek. Kemudahan dalam penggunaannya menjadikan SMS sebagai salah satu pengirim pesan yang banyak digunakan. Menurut Jamie Tolentino dalam artikelnya yang berjudul “Why are people still using SMS in 2015?” yang dipublikasikan dihalaman thenextweb.com mengatakan bahwa SMS merupakan cara berkomunikasi yang paling efektif dalam menjangkau pengguna dengan prosentasi 90 % dibaca dalam waktu satu menit. SMS adalah satu untuk semua solusi yang membuat siapa saja (yang mempunyai nomor ponsel) dapat dijangkau. Teknologi untuk mengirim dan menerima SMS tidak bergantung pada internet berkecepatan tinggi, yang pada dasarnya membuat siapa pun dalam masyarakat dapat dijangkau.Sistem Pelaporan Kerusakan Laboratorium merupakan sebuah sistem yang digunakan untuk mencatat berbagai permasalahan yang terjadi meliputi lokasi laboratorium, nomor komputer dan detil permasalahannya. Sistem informasi ini berbasiskan web dengan harapan sistem ini dapat diakses dari komputer manapun dan kapanpun. Dengan menggunakan sistem tersebut maka dapat dilihat secara detail segala permasalahan yang terjadi pada laboratorium sehingga pengelola laboratorium dapat menyiapkan langkah-langkah untuk menanganinya. Namun pada praktiknya banyak permasalahan yang tidak diselesaikan karena informasi permasalahan tersebut tidak sampai kepada para teknisi. Hal ini disebabkan karena untuk mengakses informasi kerusakan teknisi harus login melalui komputer sehingga memakan waktu. Dengan cara pengiriman notifikasi permasalahan yang terjadi pada laboratorium melalui sms maka setiap ada laporan permasalahan yang masuk ke Sistem Pelaporan Kerusakan akan langsung diteruskan ke teknisi secara langsung melalui pesan sms tanpa harus melakukan akses ke sistem. Hal ini dapat mempercepat proses sampainya informasi permasalahan laboratorium kepada teknisi sehingga penanganan permasalahan dapat dilakukan dengan cepat.Untuk mengintegrasikan Sistem Pelaporan Kerusakan Laboratorium dengan notifikasi SMS dapat dilakukan dengan pendekatan Service Oriented Architecture (SOA) sehingga proses integrasi tidak perlu merubah sistem yang sudah ada.Kata Kunci : Sistem Informasi, Service Oriented Architecture, SOA, Kylix, SMS GatewayABSTRACTThe Short Message Services (SMS) service is one of the mobile phone network services used to deliver short messages. Ease of use makes SMS as one of the most widely used message senders. According to Jamie Tolentino in his article entitled "Why are people still using SMS in 2015?" Published on page thenextweb.com said that SMS is the most effective way to reach users, with a 90 percent read rate in minutes. SMS is a one- size- fits- all solution which makes anybody (with a mobile number) reachable.The technology for sending and receiving SMS is not reliant on high speed internet, essentially making anyone in modern society reachable.Laboratory Damage Reporting System is a system used to record various problems that occur include the location of the laboratory, computer number and details of the problem. This information system is web based in the hope that this system can be accessed from any computer and anytime. By using the system it can be viewed in detail all the problems that occur in the laboratory so that the laboratory manager can prepare the steps to handle it. But in practice many problems are not resolved because the problem information is not up to the technicians. This is because to access the information the technician must log on through the computer so that it takes time.By way of notification of problems that occur in the laboratory through sms then any existing problems report into the Laboratory Damage Reporting System will be directly forwarded to the technician directly through sms messages without having to access the system. This can speed up the process of getting the information of laboratory problems to the technician so that problem handling can be done quickly.To integrate Laboratory Hazard Reporting System with SMS notification can be done with Service Oriented Architecture (SOA) approach so that the integration process does not need to change the existing system.Keywords : Information Systems, Service Oriented Architecture, SOA, Kylix, SMS Gateway

The visionary promise of Service-Oriented Computing (SOC) is a world-scale network of loosely coupled services that can be assembled with little effort in agile applications that may span organizations and computing platforms. In practice, services are assembled in a Service-Oriented Architecture (SOA) that provides mechanisms and rules to specify, publish, discover and compose available services. The aim of this chapter is to present the different technologies implementing the new paradigm of SOA: Web Services, UPnP, DPWS, and service-oriented component OSGi and iPOJO. These technologies have been developed and adapted to multiple domains: application integration, pervasive computing and dynamic application integration.

Current protocols to agree to Web/Grid service usage do not have the capability to form negotiated agreements, nor do they take into account the legal requirements of the agreement process. This article presents a framework and a domain-independent negotiation protocol for creating legally binding contracts for service usage in a distributed, asynchronous service-oriented architecture. The negotiation protocol, which builds on a simple agreement protocol to form a multiround “symmetric” negotiation protocol, is based on an internationally recognized contract law convention. By basing our protocol on this convention and taking into account the limitations of an asynchronous messaging environment, we can form contracts between autonomous services across national and juridical boundaries, necessary in a loosely coupled, widely geographically distributed environment such as the Grid.

Contemporary architectural approach is for an orchestrated, agnostic, federated enterprise through the adoption of loosely-coupled open Service interfaces. The Service-Oriented Architecture (SOA) paradigm unifies dis­parate, heterogeneous technologies. It resurrects legacy technology silos with a Service ‘face-lift’ while maintaining their autonomy. Somewhat in its infancy as standards and methodologies are evaluated and adopted, the differences between theory and praxis of SOA remain to be fully de­termined, predominately due to the size and complexity of the conundrum it addresses.

The established global business environment is under intense pressure from Asian countries such as Korea, China, and India. This forces businesses to concentrate on their core competencies and adopt leaner management structures. The coordination of activities both within companies and with suppliers and customers has become a crucial competitive advantage. At the same time, the Internet has transformed the way in which businesses run. As the Internet becomes a cheap and effective communication channel, businesses are quick to adopt the Web for integrating their systems together and linking them with their suppliers and customers. Current enterprise computing using J2EE (Java 2 Platform, Enterprise Edition) has yielded systems in which the coupling between various components in them are too tight to be effective for ubiquitous B2B (business-to-business) and B2C (business-to-consumer) e-business over the Internet. This approach requires too much agreement and shared context between business systems from different organizations. There is a need to move away from tightly coupled, monolithic systems and toward systems of loosely coupled, dynamically bound components. The emerging technology, Web services, provides the tools to accomplish this integration, but this approach presents many new challenges and problems that must be overcome. In this article, we will discuss the current approaches in enterprise application integration (EAI) and the limitations. There is also a need for service-oriented applications, that is, Web services. Finally, the challenges in implementing Web services are outlined.

In this paper a generic service oriented architecture for the semantic annotation of conceptual models is described. It allows to annotate elements of conceptual models with concepts from formal semantic schemata. Thereby, additional semantic functionalities for models can be realized. Due to the integration of aspects of service orientation, the platform can be easily extended to support different modeling and semantic schema languages. Furthermore, it can act as an integration platform for other tools working on models and ontologies.

Server Architecture

This Distributed systems have evolved rapidly as the demand for independent design, and deployment ofsoftware applications has increased. It has emerged from the monolithic style of client-server architecture toservice-oriented architecture, and then to the trending microservices. Monolithic applications are difficult toupdate, maintain, and deploy as it makes the application code very complex to understand. To overcome the designand deployment challenges in monolithic applications, service oriented architecture has emerged as a style ofdecomposing the entire application into loosely coupled, scalable, and interoperable services. Though SOA hasbecome popular in the integration of multiple applications using the enterprise service bus, there are fewchallenges related to delivery, deployment, governance, and interoperability of services. Additionally, the servicesin SOA applications are tending towards monolithic in size with the increase in changing user requirements. Toovercome the design and maintenance challenges in SOA, microservices has emerged as a new architectural styleof designing applications with loose coupling, independent deployment, and scalability as key features.
