Abstract

The embodiment of the invention discloses a management method for a virtual port. The management method comprises the following steps of selecting an optical channel data unit ODU for transmitting network service; and sending a message for constructing the virtual port to a corresponding network element in an optical transport network OTN, so that the network element constructs the virtual port matched with the ODU according to the information of the ODU in the message and the service type of the network service required to be transmitted by the virtual port. The embodiment of the invention also discloses a management device for the virtual port. By the method and the device, layers of the network can be reduced when a plurality of networks communicate with one another, the management is convenient and the network operation and maintenance of operators is facilitated.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a virtual port management method and device. Background technique [0002] In the field of communications, traditional networks are layered and managed separately, such as in Optical Transport Network (OTN), Synchronous Digital Hierarchy (SDH) ) network coexistence architecture, OTN is generally used as the underlying service layer, and it is constructed separately from SDH network or PKT network as different networks. Because OTN supports wavelength division multiplexing and has a large bandwidth, which is conducive to the transmission of large-capacity data, if the SDH network elements in the SDH network need to transmit data through the OTN, it is necessary to link the SDH network elements with the OTN network elements in the OTN They are connected through additional optical fibers, and an additional customer service layer for transmitting SDH network services is estab...
