Abstract
Dynamic Multipoint Virtual Private Network (DMVPN) is a Cisco IOS software solution for improvement scalable IPsec Virtual Private Network (VPN) that allows communication between branches over the Internet without requiring a permanent VPN tunnel between sites. DMVPN is a new technology that combines multiple GRE (MGRE) Tunnels, IPsec encryption and NHRP (Next Hop Resolution Protocol) that consist of two mainly deployment designs such as static hub to spoke and dynamic spoke to spoke IPsec tunnels. The security of data is an important aspect and encryption algorithm play an important role to provide the security to data. In this research, a performance and comparison of encryption techniques (AES, 3DES, DES) using Dynamic Virtual Protocol Network (DMVPN) Technology by GNS3 and real Cisco devices with different parameters (throughput, jitter and packet loss) based on transferring data and video streaming were presented. The results of this study indicate that the AES encryption has better performance to provide optimum performance in the network.
