Abstract
A method for detecting and discarding stale cells following route changes in a data communication network. The data communication network comprises a transmitter, which upon detection of a failure in a route of a network, retransmits data tagged as resent data along a different route of a multi-stage switch; and a receiver, which upon detection of tagged data from the transmitter via the different route of the multi-stage switch, utilizes tagged data for data communications while discarding previously transmitted data that are not tagged to avoid data duplication.
