Subject: Token Ring to Ethernet.

Copying from Token Ring to Ethernet and vice versa. Here's the answer.

Ethernet data frame size is 1,500 bytes, Token Ring frames range in size from 4.000 bytes to 18,000 bytes. Moving packets from Ethernet to Token Ring, the router simply takes the data from the Ethernet packet and places it inside of a Token-Ring packet. Going the other way the router must repackage one Token Ring packet into several Ethernet packets. This repackaging is what's taking the extra time.
