IntroductionIntroduction
What is NNCS?
National Network Centric System is a military platform for information
warfare that takes advantageof the hidden data transmissionto gain informational lead over
a potential enemy.

HPB is the connection between two types of data links.
There are two types of HPB:-HPB-H (hardware bridge)-HPB-S (software bridge)
