Abstract

A network experience rating system and method determines a network connection quality for a computer by monitoring characteristics of data traffic through a connection with another computer on the network. The network experience rating system statistically analyzes the characteristic data and compares the statistically analyzed data to historical data gathered for the computer. The network experience rating system thus provides a rating that is individualized for a particular computer based on the computer'"'"'s network usage.
