Abstract

The invention provides a method and device for processing POTN (Packet Optical Transport Network) virtual interfaces. The method comprises the steps of selecting optical fiber links through expansion and confirming a new link connection relationship; backtracking to generate connection interface groups in ports according to the new link connection relationship; confirming an application scene of each connection interface group; searching old POTN virtual port groups in a tunnel cross-segment relationship before expansion according to the application scenes; and determining new old POTN virtual port pairing groups according to the old POTN virtual port groups. According to the method and the device, the complicated cross-segment pairing relationship of NNI (Network Node Interface) service based on the POTN virtual interfaces under POTN expansion is overcome, and a POTN virtual interface pairing relationship can be calculated automatically.

Description

technical field [0001] The invention relates to the field of network management systems in the communication field, in particular to a method and device for processing POTN virtual interfaces. Background technique [0002] With the rapid development of 4G services, in order to meet the challenges of mobile broadband services and fixed integrated broadband services, packet transport networks and OTN (Optical Transport Network, Optical Transport Network) networks have been deployed in large-scale trunk lines and metropolitan areas. The integration solution with OTN, POTN (Packet Optical Transport Network, Packet Optical Transport Network), has also begun to be applied on a large scale in engineering, and the corresponding network expansion requirements have also followed. However, the expansion scenario after PO (PTN and OTN) hybrid networking puts forward new requirements for the traditional expansion method based on optical fiber links. [0003] Traditional PTN (Packet Tran...
