Estimate of Maximum Network Throughput

Audience: All

Date: March 20, 2002

Sizing a network? If so, throughput reaches saturation at around 80 percent of its rated capacity. Given this "rule of thumb", the guidelines for the maximum network throughput are:

Formula: MB/sec = (Mb/sec)(80%)/(8Mb/MB)

Standard Disclaimer: "You mileage may vary" and these numbers are optimistic as they do not reflect other network traffic such as broadcast, SNMP, DNS or routing delays, application overhead, system load, etc.
