My question was not with the interpretation of the Dave's data, but with the fact that you only saw one week's data. I have been looking at throughput data for the mailbridges every day for almost a year. I saw a different picture. In fact, the week covered by Dave's data did show a rise in the proportion of traffic going to MILISI. Before that week MILARP, MILBBN, MILDCEC, and MILISI all received about the same amount of traffic; MILLBL, MILSAC, and MILSRI received less. We saw MILISI receiving more than its share of traffic all month, but last week the traffic distribution again looked even. Such fluctuations in traffic are common. They are worth attention only when they persist and cause problems. In any case, your memory increased the disparity in the traffic distribution. The weekly averages are given below. The drop rates varied. Sometimes they were as high as 4%, sometimes they were low. We, at BBN, are looking into this problem. DATAGRAMS RECEIVED PER SECOND, averaged over one week 6/2 6/8 6/16 6/23 MILARP 7.21 6.59 5.95 6.17 MILBBN 9.09 9.82 8.71 9.02 MILDCE 7.62 8.24 7.12 8.79 MILISI 9.31 12.08 10.13 9.68 MILLBL 6.06 6.25 5.41 5.26 MILSAC 4.92 6.24 5.76 4.48 MILSRI 3.88 4.31 3.67 3.26 Perhaps, the people at ISI, who were so good about admitting to their penchant for cross-network ftping, will have an explanation for the extra traffic last month. Actually, the answer is more likely to come from across the network, since the increase in MILISI's traffic was accompanied by a drop in everyone else's traffic. Marianne
