Typically, advertised upload rates are 1/4 the download rates [30] however the available upload bandwidth using DOCSIS 1.1 or 2.0 is also lower. If 100 users allocated 1.75 Mbit/s of upload bandwidth share a single DOCSIS 1.1 upstream, the upload oversubscription ratio is 17:1. One article found a typical DOCSIS download oversubscription ratio to be 28.125:1, while a best case oversubscription may be 12:1.[2]
