>In contrast, the primary thrust of SOS is the definition of an >integrated ROS/ACSE/presentation/session stack that will offer >OSI-like services to application protocols. Although three of the We see two major technical problems with OSI: 1) the complexity of the technology (ASN.1, ACSE, Presentation layer) discourages the development of OSI applications. 2) Although ULCC's X window on OSI implementation is extremely fast, there is no efficient implementation of OSI supporting general distributed computing comparable to TCP/IP based RPCs. We have a general distributed computing environment running on top of ISODE's ACSE/ROSE. Our tools have solved the 1st problem (more friendly than RPCs). However, the 2nd problem can only be solved by an efficient stack. Several companies, including COS, HP and DSET, are currently working on the same problem, that is to provide an efficient implementation of ROSE/ACSE/presentation/session stack. I would like to see a collaboration among various companies working on the this problem so that we will not produce duplicated and incompatible stacks. There are some related International Standards Profiles being defined in the standards community: 1) DISP 11183-1: specification of ACSE, presentation and session protocols for the use by ROSE and CMISE 2) DISP 11188-1: Common Upper Layer Requirements- Part 1: Basic connection oriented requirements 3) DISP 11188-2: Common Upper Layer Requirements- Part 2: ROSE-based Profiles We hope to see these two documents can merge and an efficient ROSE/ACSE/presentation/session stack can be implemented. This would satisfy the need of CMIP, X.500, X.400 UA, and the future ISO RPC. (Other application layer protocols need a full OSI stack.) As the first step of this collaboration, I would like to collect names of those who are involved in SOS, Skinny stack, and ACSE/ROSE ISP. If you are working on any of these, or know someone else does, please send me an email. I will then facilitate the exchange of opinions and comments among the participants, and hopefully get a consensus on what need to be done and how the work can be divided. If there is a better forum, please let me know and I will be happy to contribute rather than to coordinate. Thanks. Dan Shia ---------- Dan Shia UUCP: uunet!dset!shia DSET Corp.
