PROCEDE DE DETECTION ET LOCALISATION D'UNE PERTE DE CONNECTIVITE AU SEIN D'UN RESEAU DE COMMUNICATION

摘要

The method involves making a decision that loss of unidirectional connectivity affecting communication streams originating from a standby interface (PB) or destined for a main interface (PA) is declared if a secondary monitoring frame stream (302) is not received by the main interface. Another decision is made that loss of bidirectional connectivity affecting the communication streams originating from or destined for a calculation unit (103) is declared if a primary monitoring frame stream (301) or the secondary monitoring frame stream is not received by one of the interfaces.
