Network latency will be a critical performance metric for the Fifth Generation (5G) networks expected to be fully rolled out in 2020 through the IMT-2020 project. The multi-user multiple-input multiple-output (MU-MIMO) technology is a key enabler for the 5G massive connectivity criterion, especially from the massive densification perspective. Naturally, it appears that 5G MU-MIMO will face a daunting task to achieve an end-to-end 1 ms ultra-low latency budget if traditional network set-ups criteria are strictly adhered to. Moreover, 5G latency will have added dimensions of scalability and flexibility compared to prior existing deployed technologies. The scalability dimension caters for meeting rapid demand as new applications evolve. While flexibility complements the scalability dimension by investigating novel non-stacked protocol architecture. The goal of this review paper is to deploy ultra-low latency reduction framework for 5G communications considering flexibility and scalability. The Four (4) C framework consisting of cost, complexity, cross-layer and computing is hereby analyzed and discussed. The Four (4) C framework discusses several emerging new technologies of software defined network (SDN), network function virtualization (NFV) and fog networking. This review paper will contribute significantly towards the future implementation of flexible and high capacity ultra-low latency 5G communications.

“…Thus, it allows executing unmodified guest OS by emulating one instruction set by another through translation of code. Un-like pure emulation, binary translation is used to trap and emulate (or translate) a small set of the processor instructions [7]. That is, the code that needs privileged execution, in Ring 0, such as kernel-mode.…”

Virtualization is an important technology in data center environment due to its useful features such as server consolidation, power saving, live migration and faster server provisioning. However, virtualization sometimes incurs some performance loss. Operating system-level virtualization could be an alternative to classical virtualization as it potentially reduces overhead and thus improves the utilization of data centers. Different virtualization platforms differ in terms of features, performance and virtualization overhead. Web conferencing systems become popular as the clients' bandwidth has increased in last years, in educational, researching and business fields. The BigBlueButton is a web conferencing system that allows multiple users join a conference room, having classes and share their microphone, webcam, desktop and files. In this paper, we use KVM, OpenVZ and Linux Containers as virtualization platforms to deploy conference systems using BigBlueButton. We explore its virtual performance under a real-world workload and a set of benchmarks that stress different aspects such as computing power, latency and memory, I/O and network bandwidth. These results can be a valuable information to be taken in account by systems administrators, for capacity planning and systems designing. Which, in turn, lead to cost savings for companies.

“…The release and spread of virtualization platforms has allowed the development of cost-effective information systems capable of providing dynamic resource management and simplified system administration [2], [3]. Thus, the educational process in the fields of informatics, computer science, information technologies and communications or other related domains can be optimized to minimize the cost of educational lab resources [4], [5].…”

This paper presents an evaluation of different methods used to deliver virtual machines capable of being accessed remotely by thin-clients. The objective of the research was to provide a recommendation for building a cost-effective computer infrastructure for use in two scenarios: as a programming lab, and as an office infrastructure.We have found that different thin-client solutions based on single board computers are reliable solutions for commercially available thin client replacement, because they can run free Linux-based operating systems, can handle Remote Desktop Protocol, have lower acquisition costs, lower power consumption and offer almost the same computing performance.For providing remote desktops, there are several methods and virtualization platforms available. We benchmarked some of these platforms in order to choose the one best-suited for implementation. Our conclusion is that Microsoft Remote Desktop Services outperforms the virtualization based solutions, but it entails high license fees. Of the virtualization solutions tested, the VMW are ESXi based one is the most reliable choice.
