[ENet-discuss] Safe to increase ENET_PEER_PING_INTERVAL?

[John Wood]

Hi there,

I wanted to know if it's safe to increase ENET_PEER_PING_INTERVAL, which
determines how often a ping is sent

Background: I'm using e-net for reliable data transfer only (no unreliable
packets).

I noticed it's quite "chatty" - sending a ping every 100ms
(ENET_PEER_PING_INTERVAL).

I wanted to reduce this chattiness, as I'm not sure I need it. I'm guessing
that it's chatty a) to act as a keepalive to make routers keep forwarding
packers and/or b) to update info about metrics e.g. RTT.

So I increased ENET_PEER_PING_INTERVAL to 5000 and it works perfectly. I
even tried 20000 and it still works (though I think this is too high as we
run the danger of aggresive firewall/routers thinking the "connection" is
dead).

My question is this: is there any other unintended consequences of
increasing ENET_PEER_PING_INTERVAL to, say, 5000?

It's only used in the code once, for determining when to ping, but I
wondered if other things might rely on that hard coded value. E.g., will
peers "time-out" too regulalry now? Will it break some of the "latency"
metrics e-net gathers?

I can't see any problems, but I want to be sure.

Regards,

John Wood
