Internet Protocol Security (IPSec) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a data stream. IPSec architecture requires the host to provide confidentiality using Encapsulating Security Payload and data integrity using either Authentication Header or Encapsulating Security Payload and anti-replay protection. IPSec has become the most common network layer security control and, a widely deployed mechanism for implementing Virtual Private Networks (VPNs). This paper presents analysis of IPSec VPN for videoconference in real time traffic over a secure communication links by implementing an IPSec-based VPN technology.
