ISP going back to Bell bouncy speed

The following chart illustrates some typical network connections and how they contribute to the network "quality":

Bandwidth Latency Errors (one way) 28.8 Analog Modem 3.0 KB/sec 120 ms moderate 28.8 No Compression 2.0 KB/sec 70 ms high 56K Analog Modem 5.0 KB/sec 100 ms moderate ISDN Digital Modem 4-8 KB/sec 20 ms low Direct Serial 10-115 KB/sec 20 ms moderate Ethernet (0-1 hops) 2-12 MB/sec <5 ms low Ethernet (2-3 hops) 1-4 MB/sec 10-30 ms low Ethernet (4-6 hops) 0.5-1 MB/sec 50-100 ms moderate Ethernet (distant) <200 KB/sec >100 ms mod-high

Remember that bandwidth is limited by the poorest link, but latency and network errors are cumulative. The values above are simply guidelines for "good" links -- a poor router or link may adversely affect one or more measures. The further data has to travel between hosts, the more traffic it must compete with and the more resources it uses.
