(1) What size limit on UDP packets is imposed by the
UDP specification?
(2) What size limit on UDP packets is imposed by the
operating system (Windows, Linux, ...), and how
can I query the OS for these limits?
(3) What is the practical limit of UDP packets going across the
wild Internet, through dozens of routers with various
policies?
(I know UDP is "unreliable", but I'd like to push UDP
packet size as high as possible without significantly
increasing the risk of UDP packets being quietly
dropped along the route to their destinations.)
My ignorant guesses would be the following:
(1) Less than limit on payload part of single Ethernet
frame: (1526 Bytes - 26 Bytes) = 1500 Bytes (roughly)
(2) Same as (1)
(3) Same as (1)? Or perhaps much less (realistically speaking)?
