Defining keepalive functionality
Keep-alive mechanism works through two simple steps.
First step is STANDARD ping proofing
. This ping periodically checks if link is alive. Standard
ping has 4 packets which are sent over the link and if all 4 are returned keep-alive remains in standard ping
proofing mode. If two or more of 4 packets are dropped keep-alive activates ADVANCED ping proofing.
ADVANCED ping proofing is second step
in link quality detection. Advanced ping proofing sends
5 ping packets in short period of time and gives statistic how much packets are dropped (for example if 4
packets are dropped, ping lost is 80%). If this value is defined as 100% for example, that means only if all
packets are dropped action will be performed (PPP restart). Value which is entered here depends on that
how many packets can be tolerated to lose on the link. For example if value 60% is entered 2 packets of 5
(40%) are lost, keep-alive is returned to step one (standard ping proofing) with no action performed. If PPP
should be restarted only when all packets are dropped defined value should be 100%.
In following example keepalive is enabled on SIM card. Settings are following:
SIM
Ping target: 8.8.8.8
Ping interval: 120
Advanced ping interval: 10
Advanced ping wait for response: 5
Maximum number of failed packets: 80
Keepalive action: Restart PPP
