Abstract
An error checking method and apparatus for appending a variable number of redundancy coding information at the end of each data message or packet transmitted over a multi-stage network for the purpose of protecting the data by using an error detecting code. The amount of additional redundancy coding information implemented is variable and increases with the size of the data message or packet to provide a consistent level of protection.
