ETSI announces containerised VNF specifications


The first specification enabling containerized VNFs to be managed in an NFV framework has been unveiled.

The ETSI group on Network Functions Virtualization (ETSI ISG NFV) has published ETSI GS NFV-IFA 040, which specifies requirements for service interfaces and an object model for operating system (OS) container management and orchestration.

“The release of this first specification is a key milestone for network function virtualization and confirms that ETSI ISG NFV can quickly embrace new technologies for cloud-native VNFs to support communication service providers with standardized, interoperable solutions. These new specifications provide a baseline for the integration of OS container management and orchestration into the NFV framework,” said Jörg Aelken, vice-chair of the ETSI ISG NFV IFA working group.

ETSI GS NFV-IFA 040 describes the new functions required for the management and orchestration of OS containers, the container infrastructure service management (CISM) and the container image registry (CIR). The CISM is responsible for maintaining the containerized workloads and manages the OS container, computation storage, network resources and their configuration. The CIR is responsible for storing and maintaining information of OS container software images.

The GS is supplemented by the first NFV Release 4 specifications ETSI GS NFV-IFA 010 and ETSI GS NFV-IFA 011 which provide enhancements of the specification of management and orchestration functional requirements, and extensions of the VNF package and VNF descriptor specifications respectively.
