comment Is there a maximum delay an UDP packet can have?
@AndonM.Coleman Yes, I have a lot of state which is still useful when it arrives late, but on the other hand the later a delayed packet can be handled the longer I have to cache some information (e.g., sequence channels for deleted items so they don't get recreated). If 95% of the packets arrive in 'ping + x' seconds anyway I would happily discard all packets arriving after 'ping + x' seconds. I don't have the opportunity to profile this on a lot of connections, so I wonder is there is some experience/research out there?

comment How can I create a buffer suitable for dynamic updates in SharpDX?
For the specific case of updating a buffer every frame (a buffer declared with ResourceUsage.Dynamic) part 2 of the answer (Map with MapMode.WriteDiscard) should be used. See msdn.microsoft.com/en-us/library/windows/desktop/…

@AndonM.Coleman I am already handling dropped and late packets. This question evolved out of curiosity about realistic delays in the internet. I should have stated that better.

Do you have any experience on the actual value of "x"? As I said, this is pure curiosity, I already handle dropped packets and discard packets if they are over 60s late :)

So I should have included my research about TTL into the question ^^ "In theory, under IPv4, time to live is measured in seconds, although every host that passes the datagram must reduce the TTL by at least one unit. In practice, the TTL field is reduced by one on every hop. To reflect this practice, the field is renamed hop limit in IPv6."
