Title: METHOD AND DEVICE FOR PROCESSING POTN VIRTUAL INTERFACE
Abstract:
A method for processing a POTN virtual interface, comprising: selecting an optical fiber link by means of capacity expansion and determining a new link connection relationship; generating connection interface groups inside a port by backtracking according to the new link connection relationship; determining an application scenario of each of the connection interface groups; generating an old POTN virtual port group by searching a tunnel cross-segment relationship prior to the capacity expansion according to the application scenario; and determining a new POTN virtual port paired group according to the old POTN virtual port group. The method overcomes the complicated cross-segment pairing relationship of an NNI service based on a POTN virtual port in the case of POTN capacity expansion, and can automatically calculate the POTN virtual port pairing relationship.
