Abstract

Un metodo per determinare l'affidabilìtà dei collegamenti in un sistema di trasmissione di dati comprendo il trasmettere un flusso di dati contenenti una sequenza di integrità di dati e almeno una sequenza di conteggio di errori accumulati lungo uno dei collegamenti, Il determinare l'íntegrità dei dati nel flusso alla fine del collegamento usando la sequenza di integrità di dati, l'aggiungere un conteggio di errori di dati rilevati alla sequenza di conteggio di errori accumulati, ce il rilevare periodicamente il conteggio come misura dell'affidabilità.
