General Information
Here is some basic information about Citrix ADC.
Operating System and Architecture
Citrix ADC is based on the open source operating system FreeBSD. Unlike the very similar Linux, FreeBSD has a modular kernel and Citrix has taken advantage of this to modify FreeBSD’s Bash shell by removing the networking subsystem and replacing it with its own. The modifications were placed in a custom kernel module called NetScaler Core Packet Processing Engine (PPE).
