Enhancing Branch Office Network Availability Using Cloud EoIP Gateway

Abstract

Abstract Since internet service is mostly available in many countries, tunneling solution over an internet link often used in the company for network communication between its multi-regional branches. The current state of the art solution consisting of an EoIP tunnel combined with IPsec installed on the Head Quarter of the company. Researchers see this solution as prone to total network disruption when the HQ loses its internet service. With the rising trend of cloud computing development, researchers then propose a multi-region network infrastructure design consist of MikroTik devices and Cloud platforms using EoIP IPsec protocol. Cloud platform used as an EoIP IPsec gateway due to its high availability. From the implementation and testing, the EoIP Cloud gateway proved to have high network availability. Branch network communication proved to be running well with no impact on the HQ loss of internet services. IPsec also proved to be secure enough to secure user data transmitted over the internet. From the QoS findings, there is a 24ms drop in delay performance and 0,66 ms drop in jitter performance. The EoIP IPsec on cloud platform also proved to have a 0,97% improvement in throughput performance and has a 0% packet loss rate.
