iP3 System User Manual

iP3 stands for Internet Protocol Processor Platform. It is a platform solution for transporting IP traffic via satellite. It provides transparent connectivity over the satellite link. If the optional IPmax feature is purchased, it also translates TCP data to a satellite-optimized protocol that enhances throughput. An iP3 gateway consists of an iP3 chassis equipped with transmitter and/or receiver cards. It must be connected to a third party Outdoor Unit (ODU) via inter-facility link (IFL) cables, and in some cases, by RS485 or RS232 cables. If a radio support module is purchased, the radio can be managed and controlled via the iP3 gateway.
The installation and initial network test of the iP3 Gateway is described in the iP3 installation manual.

This document describes the management and configuration features of the iP3 Gateway that are used by an administrator both during and after initial installation.

The iP3 Gateway is an industrial computer platform that includes proprietary PCI plug-in modules such as satellite modulators, demodulators, and an Ethernet interface. It is connected via IFL cables to the ODU. The operating system on the iP3 is a version of Linux (kernel 2.2) that has been optimized for iP3. The remainder of the software running on the iP3 is proprietary to Kromos and provides the services required.

The following components are some of the Kromos software suite that runs on an iP3 Gateway.
• ip3eth – the device drivers that handle all data coming in and going out of the iP3
• snmpd – the SNMP agent that handles all SNMP requests from external management systems
• httpd – allows a user with a web browser to access WebConfig
• halibut – the radio control process that handles all communications with the satellite radio. The radio supported depends on the radio option purchased with the iP3
• IPmax - the satellite optimized protocol that handles TCP/IP packets. It is present only on systems that include the IPmax option.
In addition, there are various programs that aid in the configuration and maintenance of the system. These are described later in this document.
