Subject: DLSw Feature Matrix

DLSw SIG Members -

    Most of the features that cisco wants in DLSw have already been covered
    in prior postings from Wellfleet, Netlink, and Novell.  However, I do
    have 2 features that haven't shown up yet:

	(1) DLSw integration with APPN NN on the same router, and
	(2) a DLSw MIB

    Number (1) is the one I brought up at the AIW and number (2) is one
    I think we ought to constantly consider as we define and refine the
    feature content.  Most of the DLSw SIG members are also members of
    the SNA MIB Working Group at the IETF so I don't forsee any
    problems minimizing the overlap in coverage with the DLSw MIB.

    Speaking of the SNA MIB Working Group: there was an interest matrix
    constructed by company just prior to the last IETF that gave a good
    view of the level of interest in various portions of the MIB.  I've
    created a similar interest matrix for the features of DLSw that
    we've been kicking around.

    For now, I've merely placed an "X" in the coordinates that
    represent a feature of DLSw that a company has expressed an interest
    in.  Later on, we can refine this matrix to show actual areas of
    work.  Please feel free to add more rows as we add features.  We
    might have to adjust the number of columns if more companies
    respond (probably best to duplicate the matrix).

    As this matrix is passed around via email and edited, the store and
    forward nature of email will show up as out-of-sync copies of the
    matrix.  After a period of quiescence (say 2 days), I'll create a
    consistent copy of the matrix and post it.  
    
    I may live to regret that last paragraph :-).

I would like to add to the matrix that 3Com is also interested in:
	priority
	COS
	capability exchange
	flow control

I would also like to clarify that support of Ethernet entails support
of Spanning Tree Protocol in DLSw.
