“…Results from the simulation show that VLAN outperforms LAN networks in terms of bandwidth and security, which was achieved by reducing the throughput in both sending and receiving levels to the confidential servers and also reducing the broadcast domain thereby achieving greater power efficiency. With regards to file and packet transfer, VLAN showed lower delay and increased throughput over LAN providing advantages in terms of installation flexibility and configuration speed" [5].…”

Designing and deploying an efficient and cost effective network that will satisfy end users requires a careful consideration of the different network devices that are available and selecting network parameters that will guarantee optimum performance. In this study, Riverbed modeling software was used to simulate and study the effects of varying different network parameters and devices on the performance of a local area network (LAN). Starting off with the designated Simple Network and Busy Network, the network parameters were varied for other scenarios to investigate the effects of network background utilization, link type, as well as the number of servers. Results from the simulation show that for a local area network, the web server demonstrated the highest CPU utilization. While increasing the background utilization of the network increased the remote server access time, FTP get download time, and HTTP request page response time, replacing the three servers with a single server did not have any significant impact on the CPU utilization. Further results from the simulation show that using cables enhanced the data transmission rate, and rather than deploying multiple servers, effective selection and distribution of network services can be used to achieve optimum network performance using a single server. This is achieved by striking a balance between frequently utilized network services and non-frequently utilized network services.

“…The traffic engineering solved this issue by utilizing some tunneling techniques such as virtual local area network (VLAN). VLAN is a technology that, is separated from the physical core network, which could configure logical networks on layer 2 (data link layer) [7]. This technique allows making a reservation for some network resources for specific traffic.…”

Software-defined network (SDN) is one of the most predominant technologies for networking in the existing and next-generation networks. Therefore, this paper is conducted to introduce a survey for researchers who are interested in exploiting the dynamic tunneling technique to optimize software-defined wide area network (SD-WAN). The main purpose of this survey is not only to investigate the related works of dynamic tunneling with SD-WAN but also to classify this related work according to the aim of each research into the practicable categories and present the most dominated employments for tunneling with SD-WAN, specifically virtual local area network (VLAN). The performed classification accompany dynamic tunneling in SDN can be summarized into four categories as following: exploring VLAN in SDN; management of multi VLAN in SDN; recover link failure of SDN; and development of SDN by using VLAN. Finally, the intensive study of the literature in this paper discovers that the dominant path of research falls in the class that covers SDN's link failure. This class takes full advantage of SD-WANs due to offering more robust networking and restoring most communication failures. In the event of a fault, the controller could respond and recover quickly by switching to a pre-computed backup route.

Improving the detection of intrusion in vehicular ad-hoc networks with modified identity-based cryptosystem

et al. 2023

Vehicular ad-hoc networks (VANETs) are wireless-equipped vehicles that form networks along the road. The security of this network has been a major challenge. The identity-based cryptosystem (IBC) previously used to secure the networks suffers from membership authentication security features. This paper focuses on improving the detection of intruders in VANETs with a modified identity-based cryptosystem (MIBC). The MIBC is developed using a non-singular elliptic curve with Lagrange interpolation. The public key of vehicles and roadside units on the network are derived from number plates and location identification numbers, respectively. Pseudo-identities are used to mask the real identity of users to preserve their privacy. The membership authentication mechanism ensures that only valid and authenticated members of the network are allowed to join the network. The performance of the MIBC is evaluated using intrusion detection ratio (IDR) and computation time (CT) and then validated with the existing IBC. The result obtained shows that the MIBC recorded an IDR of 99.3% against 94.3% obtained for the existing identity-based cryptosystem (EIBC) for 140 unregistered vehicles attempting to intrude on the network. The MIBC shows lower CT values of 1.17 ms against 1.70 ms for EIBC. The MIBC can be used to improve the security of VANETs.
