This case deals with the experience of a school district in the design and implementation of a wide area network. The problems faced by the school district that made the WAN a necessity are enumerated. The choice of hardware and the software is explained within the context of the needs of the school district. Finally the benefits accruing to the school district are identified, and the cost of the overall system is determined.

A Software-Defined Network (SDN) on a Wide Area Network (WAN) is a computer network that is controlled and created by software. SD-WAN is an emerging research area that has received a lot of attention from industry and government. This technology offers tremendous opportunities to support the creation of consolidated data centers and secure networks. This is an innovation that allows the network to be monitored and programmed so that it can respond to network events caused by security breaches. This solution provides network security, offers a single network management console, and provides complete control over the network architecture. Also controls security in the cloud software-defined infrastructure (SDI), such as dynamically changing the network configuration when forwarding packets, blocking, redirecting, changing Media Access Control (MAC) or Internet Protocol (IP) addresses, limiting the packet flow rate etc. Using SD-WAN technology, it is possible to reduce the cost of dedicated bandwidth channels, achieve a high-quality Virtual Private Network (VPN), and the ability to automatically select a channel for certain channels. The main advantages of SD-WAN are the management of an unlimited number of devices from a single center, reducing the cost of deploying branch infrastructure. According to the results of the survey, 7 % of respondents use SD-WAN for security solutions, 14% at the piloting stage. As a result of the research, it was revealed that by 2024, to increase the flexibility and support of cloud applications, more than 60 % of SD-WAN customers will implement the SASE (Secure Access Service Edge) architecture, which is 30% more than in 2020 and the main concept - application security and cloud functions.

Design And Implementation

Local and wide area networks on college campuses in general and in student affairs in particular still represent a relatively new technology. Accordingly, literature on the design and operation of these computer systems is just beginning to appear in the academic computing journals. The purpose of this article is to contribute to the literature on networks by describing the design and implementation of a wide area network within a large division of student affairs at a major research university.

The Common

Two tele-oncology projects have been in progress since 1997 in the Province of Trento in north-east Italy. The common aim of the projects concerns the design and the implementation of a non-surgical tele-oncology system intended to provide a flexible computing environment for the joint management of oncology patients in a wide-area network. The two projects involve both hospital specialists and general practitioners treating oncological patients. The first phase of the project involves the design and implementation of the oncology teleconsultation service.

AbstractSmall-scale commercial rollouts of Cellular-IoT (C-IoT) networks have started globally since last year. However, among the plethora of low power wide area network (LPWAN) technologies, the cost-effectiveness of C-IoT is not certain for IoT service providers, small and greenfield operators. Today, there is no known public framework for the feasibility analysis of IoT communication technologies. Hence, this paper first presents a generic framework to assess the cost structure of cellular and non-cellular LPWAN technologies. Then, we applied the framework in eight deployment scenarios to analyze the prospect of LPWAN technologies like Sigfox, LoRaWAN, NB-IoT, LTE-M, and EC-GSM. We consider the inter-technology interference impact on LoRaWAN and Sigfox scalability. Our results validate that a large rollout with a single technology is not cost-efficient. Also, our analysis suggests the rollout possibility of an IoT communication Technology may not be linear to cost-efficiency.
