MCI drops 25-50% of the packets at Willow Springs, and has done for weeks now. This leads to absolutely terrible telnet latencies -- unusable, even. Is there a way to tune the TCP timing parameters to provide optimal latency under lossy conditions, perhaps at the expense of bandwidth. Retrying more rapidly, for example, would be a help. What else would be helpful?
