188 Chapter 5 † Advanced VPN Concepts and Tunnel Monitoring IP Compression IP compression is a process that decreases the size of the data segment of the TCP/IP packet. This reduction can signifi cantly improve performance on a VPN-1 device. IPSec as implemented in VPN-1 provides support for the Infl ate/Defl ate IP com-pression algorithm.
The VPN secures the private network, using encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the Nov 08, 2016 · Tunneling is a protocol that allows for the secure movement of data from one network to another. Tunneling involves allowing private network communications to be sent across a public network, such as the Internet, through a process called encapsulation. 188 Chapter 5 † Advanced VPN Concepts and Tunnel Monitoring IP Compression IP compression is a process that decreases the size of the data segment of the TCP/IP packet.
