3.3 Minimal Data Cost
The minimal data cost of the system means that link verification testing is a low cost means to
insure high availability.
The system requires 74 bytes in each direction to validate connectivity with the target IP address.
Below is a network capture of a typical set of four ping verifications.
The following chart provides some examples of total data cost for various testing frequency.
Per Day Per Month Per Year
Every Hour
3552 Bytes 105.5 KB 1266 KB
Every 6 Hours
592 Bytes 17.6 KB 210 KB
Every 12 Hours
296 Bytes 8.8 KB 105.5 KB
Every 24 Hours
148 Bytes 4.4 KB 52.8 KB
Based on 74 bytes in each direction per ping.
3.4 Manual Control via Web & Telnet
In addition to the automatic link verification, the iBoot has an internal Web Server and Telnet
Server. By pointing a web browser or telnet client to the IP address of the iBoot, the administrator
can manually power control the unit, and manage the device.
3.5 Scheduled Power Control
The system can also use a real time clock (internal or NTP Server set) to provide scheduled power
control. Examples in this application could be:
• Keep unused systems powered down until needed. In SCADA or other telemetry applications,
reporting may be done on a periodic basis. In this case, the system can be powered down to
conserve energy or minimize heat gain and powered up only when needed
• Reboot on a scheduled basis. For system with known issues, it may be advisable to reboot once
a day, perhaps just prior to a daily transmission to insure terminal availability at the critical time.
Up to 8 schedules can be set with varying frequencies
