Wavelength Division Networks (WDM) rings is a very attractive network. The key terminating equipments are add-drop multiplexers (ADMs) on the WDM networks. It is essential to find an efficient routing and wavelength assignment to a given set of traffic streams such that the total ADM cost is minimal. In this paper, we will obtain the minimal ADM number A(12,v)=v (v-1)/4 when v≡1,9 (mod 24) and v≥25.
