Folks, Upon receiving a report the PSC-GW gateway between the NSFNET and ARPANET swamps was running much better, I peeked in and shot a few scatter diagrams. The results are fantastic and seem to indicate the problems I reported last month have been solved. As you may remember, scatter diagrams revealed something wrong in the ACC 5250 interface, PSN or X.25 implementation. I was worried that this might be symptomaniac of a more pervasive problem; however, it seems at least the problem at PSC-GW has been resolved. The delays and variance are down by a factor of ten and the incremental bit rate is six times higher than when I last measured it a few days ago. It may be most interesting if either/both ACC or BBN representatives could summarize for this list what the problem was and how it was resolved. As usual, the Sun-format scatter diagrams are on udel2.udel.edu (192.5.39.88) and can be retrieved with ftp/anonymous/guest from the file psc9.bit. Dave -------
