2249.0. "PING on FDDI $ Ethernet" by 23329::BARRETTO () Mon Apr 21 1997 00:38

    Anyone,
    
    A client is comparing the speed of ethernet and FDDI is the same  when a 
    PING command is used. Is the PING command reliable, is it the right
    tool ? 
    
    tnx
    kako

	What O/S? Many do not the resolution to show the difference in speed. Secondly, sending a 512 bit message is 51.2us on Ethernet and 6.4us on FDDI (excluding token acquisition time). That will get lost in the protocol processing time to handle the echo request/reply.

	Many [ping implementations] do not [have] the resolution to show the difference in speed.
