Overview of FortiOS Carrier features

FortiOS Carrier specific features include Multimedia messaging service (MMS) protection, and GPRS Tunneling Protocol (GTP) protection.

All FortiGate units, carrier-enabled or not, are capable of handling Stream Control Transmission Protocol (SCTP) traffic, which is a protocol designed for and primarily used in Carrier networks.

Overview

FortiOS Carrier provides all the features found on FortiGate units plus added features specific to carrier networks:

MMS and GTP.

MMS

MMS is a standard for sending messages that include multimedia content between mobile phones. MMS is also popular as a method of delivering news and entertainment content including videos, pictures, and text. Carrier networks include four different MMS types of messages — MM1, MM3, MM4, and MM7.

GTP

The GPRS Tunneling Protocol (GTP) runs on GPRS carrier networks. GPRS is a GSM packet radio standard. It provides more efficient usage of the radio interface so that mobile devices can share the same radio channel. FortiOS supports GTPv1 and GTPv2.

GPRS provides direct connections to the Internet (TCP/IP) and X.25 networks for point-to-point services (connection-less/connection oriented) and point-to-multipoint services (broadcast).

GPRS currently supports data rates from 9.6 kbps to more than 100 kbps, and it is best suited for burst forms of traffic. GPRS involves both radio and wired components. The mobile phone sends the message to a base station unit (radio based) that converts the message from radio to wired, and sends the message to the carrier network and eventually the Internet (wired carrier network).
