Nella presente Norma viene specificato un protocollo di recupero che è basato su una topologia ad anello
si accetta anche il doppio anello
progettato per rispondere deterministicamente a specifici errori sulla rete.
La presente parte 6 della EN/IEC 62439 sostituisce, insieme alle parti 1, 2, 3, 4 e 5, la CEI EN 62439:2010-01 che rimane in vigore fino al 01-03-2013, di cui costituisce una revisione tecnica, poiché rispetto ad essa aggiunge:
– un metodo di calcolo RSTP (IEEE 802.1Q);
– due nuovi protocolli a ridondanza: HSR e DRP;
– sposta gli articoli da 1 a 4 e gli allegati nella CEI EN 62439-1, che costituisce la base per gli altri documenti della serie;
– sposta l'articolo 5 (MRP) nella CEI EN 62439-2, seppure con minime modifiche di tipo editoriale;
– sposta l'articolo 6 (PRP) nella CEI EN 62439-3, seppure con minime modifiche di tipo editoriale;
– sposta l'articolo 7 (CRP) nella CEI EN 62439-4, seppure con minime modifiche di tipo editoriale;
– sposta l'articolo 8 (BRP) nella CEI EN 62439-5, seppure con minime modifiche di tipo editoriale;
– aggiunge all'articolo 8 della CEI EN 62439-1 un metodo per calcolare il massimo tempo di recupero di RSTP in una configurazione ristretta (anello);
– aggiunge all'articolo 5 della CEI EN 62439-3 le specifiche del protocollo HSR secondo i principi PRP;
– introduce il protocollo DRP come CEI EN 62439-6.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
