3.4 NDEC Module

3.4.1 Introduction

Network Data Encryption Module (NDEC) supports IPSec protocol and speeds up the
encryption of IP packets by means of hardware, featuring high performance and high
reliability.
When NDEC module is inserted, the main board of the router handles IP packet
forwarding and implements the VPN with encryption features, and then the NDEC will
complete the task of encryption.
