ODU (optical data unit) management method and device

Abstract

The invention discloses an ODU management method and a device. The method comprises the steps as follows: information of an ODU bearer service type is added to an attribute or a name of an ODU management object and an ODU is managed on the basis of the information of the ODU bearer service type. The device comprises a setting unit and a management unit, wherein the setting unit is used for adding the information of the ODU bearer service type to the attribute or the name of the ODU management object; and the management unit is used for managing the ODU on the basis of the information of the ODU bearer service type. According to the ODU management method and the device, the ODU can be managed on the basis of the information of the ODU bearer service type, and ODU key information such as the bearer service type, the number of occupied time slots and a time slot list can be clearly obtained from the attribute or the name of the ODU management object, so that a network management system can effectively manage the type of management objects.

Description

technical field [0001] The present invention relates to an optical data unit (ODU, Optical Data Unit) management technology, in particular to a management method and device for an optical data unit. Background technique [0002] With the rapid development of optical networks, Optical Transport Network (OTN, Optical Transport Network) technology has been developed and applied more rapidly. Multi-level ODUk (k=0, 1, 2, 3) with fixed time slot mapping is relatively mature, and related standards strictly define the mapping process of multi-level ODUk, and management standards also define fixed time slot mapping. Management object of multi-level ODUk. At present, the diversification of applications requires OTN networks to have more flexible means of resource usage. Therefore, ODUflex and single-level ODUk that can flexibly configure time slots have emerged as the times require. It also requires the management system to be able to model and manage such management objects. Curren...

At present, the diversification of applications requires OTN networks to have more flexible means of resource usage. Therefore, ODUflex and single-level ODUk that can flexibly configure time slots have emerged as the times require. It also requires the management system to be able to model and manage such management objects. Currently, There is no clear management method for this type of management object in the standard
