IMPACT OF TUNNELING ON NETWORK CAPACITY
Knaj Nouma Khalil · SYNCHROINFO JOURNAL · 2022
For many companies, setting up a VPN for secure, encrypted communication is a cost-effective alternative to purchasing, operating, and managing a separate physical network. Many institutions, corporations, government agencies and nonprofit organizations want to have their own private IP network for secure and reliable connectivity between offices across multiple geographies. A virtual private network (VPN) is a secure, encrypted connection over a public public network. Creating a separate network requires the purchase of equipment, its installation and maintenance. A VPN-based solution using the public Internet is becoming a cost-effective solution for many corporations. As a research task, the authors define an assessment of the impact of the tunneling technology used to solve problems arising from the lack of network support from existing data transfer protocols. The possibility of using the IPSec protocol and MPLS technology to implement tunneling is considered and compared. The results of the comparison and evaluation of the impact of the choice of protocol on the required bandwidth are presented.
