The Virtual Network Function Manager (VNFM) placement in a large-scale distributed NFV deployment is therefore a challenging task due to the potential negative impact on performance and operating expense cost. The VNFM assigns Virtual Network Functions (VNFs) and operates efficiently based on network demands with resilient performance through efficient placement techniques. The degradation in performance and a tremendous increase in capital expenditure and operating expenses indicated this chaotic problem. This article proposed a method for VNFM placement using information on the resources of each nodes\u2019 Element Manager (EM), which is an efficient method to assign VNFs to each node of element management systems. In addition, this paper proposed an Optimized Element Manager (OEM) method for looking at appropriate EMs for the placement of VNF through periodic information on available resources. It also overcomes challenges such as delays and variations in VNFs workload for edge computing and distributed cloud regions. The performance is measured based on computations performed on various optimization algorithms such as linear programming and tabu search algorithms. The advent of the new service provisioning model of BGP-EVPN for VXLAN is materialized by integrating VTS with OpenStack. The numerical analysis shows that the proposed OEM algorithm gives an optimal solution with an average gap of 8%.<\/jats:p>","DOI":"10.3390\/sym14050978","type":"journal-article","created":{"date-parts":[[2022,5,10]],"date-time":"2022-05-10T21:52:11Z","timestamp":1652219531000},"page":"978","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Optimization of 5G\/6G Telecommunication Infrastructure through an NFV-Based Element Management System"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6583-2292","authenticated-orcid":false,"given":"Arunkumar","family":"Arulappan","sequence":"first","affiliation":[{"name":"Department of Computer Technology, Anna University, Chennai 600044, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gunasekaran","family":"Raja","sequence":"additional","affiliation":[{"name":"Department of Computer Technology, Anna University, Chennai 600044, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7155-7901","authenticated-orcid":false,"given":"Kalpdrum","family":"Passi","sequence":"additional","affiliation":[{"name":"School of Engineering and Computer Science, Laurentian University, Sudbury, ON P3E 2C6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aniket","family":"Mahanti","sequence":"additional","affiliation":[{"name":"School of Computer Science, University of Auckland, Auckland 1142, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2242","DOI":"10.1109\/TNSM.2020.3020390","article-title":"Study of virtual network function placement in 5G cloud radio access network","volume":"17","author":"Arzo","year":"2020","journal-title":"IEEE Trans.
