Method and an electronic arrangement for providing demand-supply service of physical communication network resource

An electronic arrangement for providing demand-supply service of physical network resources, such as host computers capable of running Virtual Network Functions (VNFs), to communication service providers, the arrangement comprising:

• data interfaces for transferring data;
• at least one processing unit for processing instructions, functions and other data;
• and
• at least one memory for storing the instructions and other data, wherein said at least one processing unit being configured, in accordance with the stored instructions, to cause:
• obtaining:
• a) indication of a communication service provider that offers physical network resources, and indication of a physical service area relating to the physical network resources offered,
• b) monitoring information describing the physical network resources that are available, such as host computer devices, said monitoring information being gathered through one or more monitoring software agents running on a network of said physical service area, and
• c) indication of conditions set by the communication service provider for allowing another communication service provider to utilize said available physical network resources for providing services to users of the other communication service provider through Network Function Virtualization (NFV) technology,
• determining VNF descriptors for the offered physical network resources based on the obtained indications and monitoring information,
• obtaining, from a system of the other service provider, a request for physical network resources in order to provide services to users of the other service provider, said request indicating a target area for the service delivery and requirements regarding VNFs to be run in order to implement the service,
• determining, based on the VNF descriptors and the request, one or more physical networks that suit running the VNFs,
• transmitting an indication of the determined suitable physical networks and said conditions to the system of the other service provider,
• receiving, from the system of the other service provider, an indication of a selection from the suitable physical networks, and
• building and delivering, based on said indication of the selection from the suitable physical networks, Virtual Network Function Manager (VNFM) specific VNF descriptors in order to supply the physical network resources for the other service provider.
