[ENet-discuss] Channels and ordering

[M. Rijks]

Hi everyone,

A question concerning channels and ordering of guaranteed and  
non-guaranteed packets. If I understand Enet well enough, channels can  
be considered different queues of incoming packets. Now consider this  
scenario: let's assume I'm sending both guaranteed and non-guaranteed  
packets on the same channel, and that Enet spends some time receiving  
a guaranteed packet (it won't 'give' the packet to me until it is  
fully received). What happens for any non-guaranteed packet sent on  
the same channel? I suppose the sending end could already have started  
to send the non-guaranteed packet, then realizing one of the  
guaranteed packets might not have arrived, and trigger a resend. Or  
does it stall subsequent packets and wait for confirmation of the  
previous message? If it doesn't stall, then on the receiving end will  
Enet keep waiting for full delivery of all parts (when the packet is  
large) before giving me subsequent packets that may have arrived in  
between?

All reactions appreciated!
