As it happened in Chapter 4, the network services are an abstraction to ease the management of your network. Each network service describes a set of ports for Internet protocols where service accepts requests. Providing a name plus an optional description allows you to manage the network service policies more intuitively and less error-prone.

The network services are used by firewall module (Chapter 6) and traffic shaping module (Chapter 19). Anyway, as eBox philosophy every feature which use a network service must use this module to work with and ease the administration life.
