Abstract

Menetelmä ja järjestely päästä-päähän -tahdistuksen ylläpitämiseksi tietoliikenneyhteydellä, jolla siirretään tietoa kehyksissä olennaisesti reaaliaikaisesti ja käyttäen tahdistettua päästä-päähän -salausta, joka tahdistetaan lähettämällä ajoittain tahdistusvektoreita mainituissa kehyksissä, ja jolloin ainakin osa tietoliikenneyhteydestä muodostuu pakettikytketystä yhteydestä (PDN), jolloin siirrettävän tiedon toistoviivettä voidaan kasvattaa lisäämällä yksi tai useampia ylimääräisiä kehyksiä siirrettävään kehysjonoon ja pienentää poistamalla yksi tai useampia kehyksiä siirrettävästä kehysjonosta, jolloin järjestely käsittää toistoviiveen säätövälineet (GW, TE), jotka on sovitettu suorittamaan tiedon lähetyksen aikana tapahtuva toistoviiveen muuttaminen sellaisella hetkellä, että muutoksen jälkeen seuraavaksi siirrettävä kehys käsittää tahdistusvektorin.
