Communication network switch e.g. Ethernet switch, for transmitting e.g. speed information of modern airplane, has management ruler permitting invalidation of communication channel by comparison with thresholds of transmission errors

摘要

The switch (10) has a switch traffic management ruler i.e. processor (20B), permitting invalidation of a communication channel by comparison with counter thresholds of detected transmission errors stored in a database (20A). The thresholds include minimum number of discarded frames, where the minimum number of discarded frames is set to a value of order of 2274 Ethernetframes when theoretical speed of the channel is in order of 100 megabits per second. An independent claim is also included for a method for detecting and treating failures of communication network switch.
