Abstract
A method and apparatus are provided for fault location in a loop network (). The network system having a host port () for supplying and receiving data and a plurality of successively connected ports () through which data from the host port () is transferred. A counter () for each port records data transfers in which the amount of data received at a destination port is less than an expected amount of data. When a transfer with less than the expected amount of data is identified for a data flow between a sending port () and a destination port (), the counters are incremented for each port () after the sending port up to and including the destination port. Analysing means determines a fault location in the network system from the distribution of counts in the counters ().
