Website Portal Alumni Amikom Yogyakarta yang dapat diakses pada alamat domain alumni.amikom.ac.id merupakan bagian dari Universitas Amikom Yogyakarta yang berfungsi sebagai sarana berbagi informasi sekaligus bertindak sebagai penghubung antara perusahaan pencari tenaga kerja dan para pencari kerja khususnya alumni Universitas Amikom Yogyakarta. Selama ini website alumni sudah berjalan belum dilakukan evaluasi terhadap kualitas layanan website yang didasarkan pada persepsi pengguna akhir sebagai umpan balik kepada pengelola website sehingga pengelola dapat mengetahui sejauh mana kepuasan pengguna dan kualitas layanan yang sudah diberikan. Tujuan dari penelitian ini yaitu untuk mengetahui kualitas layanan website alumni menggunakan tiga dimensi yang ada pada metode Webqual 4.0. Tiga dimensi itu sendiri terdiri dari Kegunaan, Kualitas Informasi, dan Kualitas Interaksi Layanan. Pendistribusian kuisioner dilakukan terhadap 200 sampel responden. Kesimpulan dari penelitian ini adalah adanya pengaruh ketiga dimensi Webqual 4.0 terhadap kepuasan pengguna. Dimensi yang paling berpengaruh yaitu Kualitas Informasi dan Kualitas Interaksi Layanan. Hal ini berarti peningkatan dapat dilakukan pada indicator yang memiliki nilai rata-rata terendah. Peningkatan pada dimensi Kualitas Informasi dapat dilakukan perbaruan secara berkala sehingga informasi yang disajikan menjadi lebih relevan. Sedangkan untuk dimensi Kualitas Interaksi Layanan dapat dilakukan dengan meningkatkan pelayanan terhadap keluhan seputar website alumni.Kata Kunci — Kualitas Layanan, Website Alumni, Webqual 4.0The Alumni Amikom Yogyakarta Website which can be accessed at the domain address alumni.amikom.ac.id is part of the Amikom University of Yogyakarta which serves as a means of sharing information while acting as a liaison between the company and job seekers, especially alumni of Yogyakarta Amikom University. So far, the alumni website has been running, yet an evaluation of the quality of website services has been carried out based on the perception of the end user as feedback to the website manager so that the manager can find out how far the user satisfaction is and the quality of the service provided. The purpose of this study is to determine the quality of the alumni website service using three dimensions that exist in the method of Webqual 4.0, there are Usability, Information Quality, and Service Interaction Quality. The conclusion of this study is the influence of the three dimensions of Webqual 4.0 on user satisfaction. The most influential dimensions are Information Quality and Service Interaction Quality. This means that an increase can be made on an indicator that has the lowest average valueKeywords— Quality of Service, Alumni Website, Webqual 4.0

The Impact

This chapter introduces quality of service in multi-access wireless networks. Specifically it demonstrates how QoS is implemented in IEEE 802.11 and UMTS. The chapter explains how these complementary technologies, when coupled together, provide a network that is greater than its individual parts. Combining these networks brings new network management challenges. To this end, the impact of joint admission control strategies on quality of service is evaluated. The evaluation is performed on an advanced test platform that replicates an integrated Release 4 UMTS network and standard IEEE 802.11b network. The results show that when UMTS and WLAN are tightly coupled, the end user enjoys a higher level of quality of service.

Delay Variation

Internet growth in recent years has encouraged many new applications to be provided for the end user. However, providing and maintaining high quality of service for these new applications is a challenging matter that is getting the attention of many many researchers nowadays. The QoS challenge is emanating from the diversity of these applications, in term of bandwidth requirements and high sensitivity to delay and delay variation. Three main architectures were proposed by IETF in an effort to make the IP QoS a reality. They are integrated services (Intserv), differentiated services (DiffServ) and multiprotocol label switching (MPLS). Sometimes perceived as competitor, these architectures are in fact complementary developments that approach the QoS challenge from different network perspectives. Thus these approaches can work together in a manner that provides a global QoS within Heterogeneous network. This paper aims to propose and discusses an improved admission control mechanism in order to achieve a global QoS in the HN Network. The proposed mechanism uses MPLS-TE tunnels at the core of Heterogeneous networks to maintain QoS for inter-domain flows and applications.

In multi-player cloud gaming two or more people from different locations may actively participate in gaming as like they were in a similar geographical location. In such cases handling massive user inputs, performance rendering, bandwidth fluctuations, load balancing, data capturing, data transmission in real time still remains a cumbersome in cloud gaming. In this chapter, we propose a framework that overcomes the major issues associated with quality of service in cloud gaming. The cloud platform consists of two environments namely workbench and runtime environment, where the work bench environment comprises of tools like end user tools, data parsing tools and data integrity tools through which the user input is analyzed and sent to the run time environment for further processing. Each tool present at the cloud platform helps in achieving the quality factors through its functionalities. The user request is processed and the results will be sent to the clients through the runtime environment.

Cloud computing is the most utilized and evolving technology in the past few years and has taken computing to a whole new level such that even common man is receiving the benefits. The end user in cloud computing always prefers a cloud service provider which is efficient, reliable and best quality of service at the lowest possible price. A cloud based gaming system relieves the player from the burden of possessing high end processing and graphic units. The storage of games hosted in clouds using the latest technologies in cloud has been discussed in detail. The Quality of service of games hosted in cloud is the main focus of this chapter and we have proposed a mathematical model for the same. The various factors in dealing with the quality of service on cloud based games have been analyzed in detail. The quality of experience of cloud based games and its relation with quality of service has been derived. This chapter focuses on the various storage techniques, quality of experience factors and correlates the same with QoS in cloud based games.

The presented approach draws on two main software techniques: Model-Driven Architecture, and aspect-oriented programming. The method involves modeling of the Quality of Service and Extra-functional properties in a platform-independent fashion. Then applying model transformation, the platform-independent models are transformed into platform-specific models, and finally into code. The code for Quality of Service and Extra-functional properties are integrated into the system relying on aspect-oriented techniques in a decoupled manner. The presented approach is evaluated with the help of a case study to establish that the approach results in increasing the system’s modularity and thus reducing implementation and maintenance costs.
