AI Technical Summary

Technical Problem

Existing NFV architectures with container management platforms face challenges in meeting the access requirements of microservices, particularly in ensuring that microservices can be accessed via layer 7 domain names, which is not supported by traditional service load balancing mechanisms.

Method used

The method involves enhancing the VNFD to include mapping information for ingress container objects, allowing microservices to be accessed through layer 7 domain names by defining ingress container objects within the VNFD, thereby satisfying the access requirements of microservices.

Benefits of technology

This approach enables effective deployment and management of network element microservices in a containerized manner, ensuring they can be accessed via appropriate domain names, enhancing flexibility and scalability.

Abstract

This application relates to the field of NFV technology and discloses an instantiation method and apparatus for a virtualized network function (VNF). The method includes the steps of: a VNFM receiving a first instantiation request from an NFVO, the first instantiation request including configuration information of a first virtual connection point of the VNF, the configuration information of the first virtual connection point including configuration information of K microservices of the NF corresponding to the VNF; further determining configuration information of a first ingress container object corresponding to the first virtual connection point, the first ingress container object being configured to provide access ingress for the K microservices; and sending the configuration information of the first ingress container object to a CISM, the configuration information of the first ingress container object being for creating the first ingress container object. In this way, an ingress container object can be created for the microservice. The access address of the microservice defined using the ingress container object can be a domain name (e.g., FQDN), so that the access requirements of the microservice can be met.
