Abstract

The invention discloses a virtualization method, device and equipment of a physical network element node and a storage medium, which are used for solving the problem that in the prior art, OTN (Optical Transport Network) physical network topology cannot cover various switching delays occurring when a service passes through different switching layers of a hybrid scheduling network element node. Themethod comprises the following steps: establishing an exchange delay link structure corresponding to a scheduling link of the physical network element node; wherein the scheduling link is a link which can be scheduled to a corresponding switching layer when a service passes through the physical network element node; and generating a virtualization time delay model of the physical network elementnode according to the exchange time delay link structure.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a virtualization method, device, equipment and storage medium for physical network element nodes. Background technique [0002] 5G (5th-Generation, fifth-generation mobile communication technology) network services have higher requirements for performance indicators such as clock accuracy, delay, and reliability. OTN (Optical Transport Network, Optical Transport Network) is usually considered to be deployed on the 5G midhaul and backhaul network. By using the SLA (Service Level Agreement, Service Level Agreement) delay level as a slice optimization strategy and using resource optimization algorithms to optimize the OTN Network resources are sliced ​​to meet the delay requirements of various 5G services that occupy corresponding slice resources. The layers of the OSI (Open System Interconnection, Open System Interconnection) network model affect the delay. U...
