Abstract

This article examines various network virtualization technologies, including Virtual Extensible LAN (VXLAN), as well as overlay network protocols such as VXLAN-EVPN (Ethernet VPN) and VXLAN-LISP (Locator/Identifier Separation Protocol). These protocols play a crucial role in improving the scalability and flexibility of big cloud computing infrastructures. While each of these technologies can be employed to expand a Layer 2 connection across an already established network, they possess unique qualities and applications. The objective is to offer a comprehensive comprehension of these technologies and their suitability in diverse network contexts.VXLAN-EVPN has higher performance in terms of encapsulation speed and reduced packet overhead, rendering it highly suitable for high-speed and large-scale deployments. Conversely, VXLAN-LISP demonstrates superior network latency and interoperability, offering benefits in multi-tenant and geographically distributed networks. VXLAN can be combined with other widely used overlay network protocols, including Generic Network Virtualization Encapsulation (GENEVE), Stateless Transport Tunneling (STT), and Network Virtualization using Generic Routing Encapsulation (NVGRE). The objective is to offer a comprehensive comprehension of these technologies and their suitability in diverse network contexts.

Author Biography

Shavan Askar, Erbil Polytechnic University

Dr. Shavan Askar (Professor of Computer Networks since 15/3/2023). He received his PhD degree in Electronic Systems Engineering from the University of Essex\UK in 2012. He obtained his MSc (2003) and BSc (2001, Ranked 1st on the college) degrees from the Control and Systems Engineering Dept. Baghdad. Dr. Askar works in the field of Networks that includes Internet of Things, Software Defined Networks, Optical Networks, and 5G. Dr. Askar has started his academic career in 2003 when he was appointed as a lecturer at the University of Duhok Iraq until 2008 when he was granted a scholarship to do his PhD degree that commenced in October 2008 and finished successfully in June 2012. Dr. Askar then returned to Iraq to pursue his academic career at the University of Duhok for the period 2012-2016 by supervising master students, teaching post-gradatue courses, and became project manager of so many strategic projects in Kurdistan. In 2016, Dr. Askar joined Duhok Polytechnic University as the Director General of Scientific Research Center, his role includes apart from teaching post-graduate students, contributing to the development of the university from the technological and scientific perspectives. Since 2017, Dr. Askar beside his DPU job is working as an Adjunct Professor at the American University of Kurdistan, he contributed into the establishment of a new program called Electronic and Telecommunications Engineering\College of Engineering, he teaches different courses in this program. Dr. Askar has more than 95 scientific research papers, some of his papers were published in very prestigious conferences such as OFC and ECOC and high impact factor journals. While he was in UK, he worked as a Researcher in two European projects; MAINS project (Metro Architecture enabling Sub wavelengths) and ADDONAS project (Active Distributed and Dynamic Optical Network Access Systems).
