Comparative Analysis of VPN Protocols at Layer 2 Focusing on Voice Over Internet Protocol

Abstract

Voice over Internet Protocols (VoIP) is an IP-based communication technology or commonly known as Internet Protocols (IP). In which, IP is currently widely used for mobile communication activities. However, the main concern in the application of VoIP technology is the system ability to maintain information confidentiality while guaranteeing protection to its primary users. For this reason, it requires to do the addition of Virtual Private Network (VPN) features. Conceptually, it aims to create connection lines in secret by utilizing the internal network structure (intranet) and to be accessed remotely using tunneling protocols in its security system. The purpose of this research is to compare the Quality of Service (QoS) on several tunneling protocols. Moreover, it is conducted to also analyze several security system mechanisms including Delay, Jitter, Throughput and Packet Loss. This analyzation is used for determining the best quality of some of the piloted tunneling security protocols. Furthermore, this work compares several methods of VoIP voicecall-testing in term of Generic Routing Encapsulation with IPSecurity (GRE+IPSec), Internet Protocol in Internet Protocol based Session Initiation Protocol (IPIP+SIP-based), Secure Socket Layer (SSL), and Layer 2 Tunneling Protocol IPSecurity (L2TP+IPSec). Accordingly, the comparative results show the better performance compared to the existing work, which is proven by the ability of the proposed method to provide the VoIP based on ITU-T.G.1010.

Performance Comparison of Zevenet Multi Service Load Balancing with Least Connection and Round Robin Algorithm

“…The Zevenet load balancing system achieves the smallest average jitter value of 33.3 ms by employing the leastconnection algorithm in the ALC5:4:1 weight distribution scheme. According to the TIPHON standards [37], the roundrobin and least-connection algorithms' Jitter computation results fall into the "Good" category, as they remain within the 1-75 ms range. The round-robin algorithm combined with Zevenet load balancing is more efficient than the leastconnection algorithm.…”

“…The simulation time is 5 minutes, and the bandwidth allocated is 1 Gbps in five trial simulations with round-robin load-sharing algorithm (RR3:2:1) (RR4:2:1) (RR5:2:1) (RR5:31) (RR 5:4:1) and least-connection algorithm (ALC 3:2:1) (ALC4:2:1) (ALC 5:2:1) (ALC5:31) (ALC 5:4:1). C. Index Parameters: QOS from TIPHON In the context of networks, quality of service is the capacity to offer customized services for various types of network traffic [35]- [37]. Better, planned network services with allocated, regulated bandwidth delay and increased characteristic loss are the ultimate goals of quality of service [38]- [41].…”

“…Equation 3 is the formula for calculating jitters. TIPHON standard values for jitter [37] as shown in Table 5. 4) Packet Loss: The parameter packet loss describes a condition that indicates the entire packet loss in data transfers that take place.…”

“…Setelah melakukan penerapan rancangan jaringan VPN menggunakan Zero Tier telah selesai dilakukan, penulis akan melakukan pemantauan dan pengujian terhadap bandwidth meliputi delay, packet lost dan jitter melalui koneksi jaringan Zero Tier yang telah diterapkan. Untuk mendefinisikan kategori QoS maka data yang didapatkan dari pengukuran tiga parameter terakhir dipotret dengan standar Telecomunication and Internet Protocol harmonization Over Network (TIPHON) [14], [15] seperti pada table 1-3 berikut ini.…”

Exploring Complex MPLS VPN Applications: Models and Implementations for Modern Communication Demands

“…VPN categorization comprises Layer-2 VPNs and Layer-3 VPNs, aligned with the OSI Model's Seven Layers. Speci cally, Layer-2 corresponds to the Data-Link layer, while Layer-3 pertains to the Network Layer [12][13]. In a Layer-2 VPN, the Service Provider's entire network is perceived by the customer as a Layer-2 Circuit/Switch.…”
