Remote access protocols for Desktop-as-a-Service solutions

Abstract

The use of remote desktop services on virtualized machines is a general trend to reduce the cost of desktop seats. Instead of assigning a physical machine with its operating system and software to each user, it is considerably easier to manage a light client machine that connects to a server where the instance of the user’s desktop machine actually executes. Citrix and VMware have been major suppliers of these systems in private clouds. Desktop-as-a-Service solutions such as Amazon WorkSpaces offer a similar functionality, yet in a public cloud environment. In this paper, we review the main offerings of remote desktop protocols for a cloud deployment. We evaluate the necessary network resources using a traffic model based on self-similar processes. We also evaluate the quality of experience perceived by the user, in terms of image quality and interactivity, providing values of Mean Opinion Score (MOS). The results confirm that the type of application running on the remote servers and the mix of users must be considered to determine the bandwidth requirements. Applications such as web browsing result in unexpectedly high traffic rates and long bursts, more than the case of desktop video playing, because the on-page animations are rendered on the server.

A multi-disciplinary review of enablers and barriers to Cloud ERP implementation and innovation outcomes

“…As such, the use of Cloud ERP to achieve innovation has received growing attention in both academia and practice in contemporary societies. Specifically, a group of four different types of cloud computing services, including Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Desktop as a Service (DaaS), can offer several strategic solutions (Lee et al, 2021;Magaña et al, 2019;Jarraya and Elloumi, 2022). Therefore, enterprises can utilise such cloud service models to efficiently generate a digital workspace.…”

Protocol-agnostic method for monitoring interactivity time in remote desktop services

“…The average transfer rates were approximately 92 Mb/s downstream and 94.6 Mb/s upstream. These rates are limited by the 100Base-T connectivity of the computers, but are still much faster than the minimum speeds required needed for remote desktop usage [20]. The average measured RTT was 7 ms, which is far below the 150 ms recommendation of ITU-T G.114 standard [13].…”

“…Some papers in the literature have addressed the characterisation of the network requirements for the PCoIP protocol used by Amazon WorkSpaces. In [20,39], it was demonstrated that the video user profile tends to be the most demanding service, requiring a transfer rate of 0.834 Mb/s in the upstream direction and 9 Mb/s in the downstream direction. Therefore, the bandwidth available for our setup is not a bottleneck.…”

“…There are different protocols that enable these services, such as PCoIP [35], the Remote Frame Buffer protocol [30], and Remote Desktop Protocol (RDP) [26]. Some of the main characteristics of these protocols are discussed in [20]. In this type of solution, computer resources are typically centralised, and remote desktops are virtualised.…”

Konsep Penerapan Metode Scrum dan RDC System Dalam Pengembangan System Mobile Taking Order Web

“…Fitur utamanya yaitu pembuatan mobile taking order, mengelola mobile taking order, melakukan pengecekan order yang sudah dilakukan, dan melakukan setoran pembayaran terhadap piutang golfer. Koneksi antara POS System dan smartphone di server pusat menggunakan koneksi RDC (Remote Desktop Computing) System [4]. Dengan munculnya system mobile taking order ini penulis berharap club house dapat memaksimalkan POS system dan smartphone untuk meningkatkan produktivitas para waitress dan kasir yang nantinya akan meningkatkan keuntungan bagi club house.…”
