Message-ID: <8809100613.AA09191@ETN-WLV.EATON.COM> Date: 10 Sep 88 06:13:05 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 20 Kent: I agree that the ISO OSI model has to be re-examined; however, I doubt that it has any particular relevance to the discussion of a protocol or any suite of protocols. While it is useful to clearly state the logical procedures that must be performed to establish a link to reliably transfer data between two (2) points on a network, it is somewhat absurd to codify these logical procedures as the ISO has done and then attempt to define a suite of protocols to implement these logical procedures. I am not stating that there is no need to have a protocol "stack"; however, I don't understand the apparent, wide-spread belief that each protocol in the "stack" must be implemented as isolated procedures or separate processes. From practical experience in implementing message handling and distribution systems and communication networks, the logical procedures defined in the OSI model are, by necessity, repeated in each layer of the protocol "stack" in order to ensure a reliable communication link.
