Now, although that makes sense, in order to avoid issues like the one we are facing with Microsoft, would it not make _more_ sense for the stack to look at the PMTU cache first, and then adjust its own MSS just for connections to that one host?
This _is_ Microsoft we're talking about, remember. 'sense' and 'Microsoft' are, at a =minimum= orthogonal to each other -- and may not even inhabit the same address-space. <wry grin> As for standards, it is official Microsoft policy to "embrace and extend", not to implement in a way compatible with the rest of the world. *sigh* I -don't- believe the rumor that "PMTUD/Vista Ultimate" sends incrementally increasing-size packets, and uses the first one that -doesn't- get through as the size limit. <giggle> _______________________________________________ NANOG mailing list NANOG () nanog org http://mailman.nanog.org/mailman/listinfo/nanog
