Abstract

Tämä keksintö liittyy reitittämiseen kommunikaatioverkossa. Keksintö tarjoaa menetelmän tehdä suojattu reititys kaikkien kommunikaatioverkkokerrosten kautta. Pohjakerros on perusta kaikille suojatuille reiteille. Ensimmäiseksi reititetään ensimmäinen pohjakerroksen yläpuoleinen kerros pohjakerrokseen. Linkit, jotka eivät tarvitse suojausta, voidaan reitittää lyhimmän polun kautta. Linkit, jotka tarvitsevat suojausta reititetään niin, että on olemassa kaksi erillistä, mahdollisimman lyhyttä polkua. Muut linkit reititetään samaan tapaan. Lopulta päällimmäinen kerros reititetään sen alapuolella olevaan kerrokseen. (Fig. 4)
