A script to determine Maximum Transmission Unit
Authored by: macubergeek on Feb 07, '06 08:56:37AM

The 802.3 standard mtu is 1514 byes. For 802.11, the IEEE lists it at 1518 bytes.
However 1500 bytes is the customary limit set on network devices.

It's been my experience that 1500 bytes is wildly optimistic on most commercial networks. So if you are running this on an enterprise network (like at work) consider 1400 bytes to be typical and expected. Now 1500 bytes on your home DSL or cable net connection might be typical though.
