Abstract

See full text

Described are methods which preserve the order of the data frames within a data stream if the data stream is switched from one link to another. The first method achieves the order preservation by numbered switch frames that have to be exchanged between the nodes before the link switching is actually performed. In the second method, the switching is only prepared by exchanging special frames which indicate 'clean' links. Actual switching takes place by just using an already prepared, i.e., 'clean' link.
