I have had a technically competent customer ask me the difference
between "PACKET" rate and "FRAME" rate. He has noticed the two terms
in various documents when looking at ethernet and FDDI networks. In
some cases the two terms appeared to be used interchangablely and in
other cases as two seperate entities.
Can some one shed some light on this?

| 2145.1 | Packet = Network layer; Frame = Data-link layer. | NETCAD::GALLAGHER | Tue Mar 28 1995 10:40 | 10 | |
This answer may be too simple-minded, but here goes.... A "Frame" is part of the Data-link layer of the OSI Reference Model, while a "Packet" is part of the Network (DECnet Routing) layer of the OSI Reference Model. Therefore, bridging performance should be quoted in frames per second and router performance in packets per second. It's still easy to be confused since the terms are not used consistently. -Shawn | |||||

Gee Shawn, you're showing your software lineage....."OSI"
Er....it's really ISO ref model. :-) Call me Mr. nit-picker. :-)
RE: .0 A frame is analogous to letters delivered by the postman.
A packet is sort of analogous to the postman delivering the letters
and will contain more control information in its format.
