Method for operating a central office point of delivery instance for a broadband access network of a telecommunications network

A system comprising a central office point of delivery instance and a central office point of delivery management entity for operating the central office point of delivery instance for a broadband access network of a telecommunications network, wherein the central office point of delivery instance is connected to the central office point of delivery management entity, and wherein:

• the central office point of delivery instance comprises a control plane, a management plane, a transport functionality, and an edge functionality, and
• the central office point of delivery management entity comprises a further control plane, a further management plane, a further transport functionality, and a further edge functionality,
• the central office point of delivery instance is connected to an access functionality being realized by means of a plurality of access nodes that terminate physical subscriber lines serving end users of the telecommunications network, the central office point of delivery instance being instantiated using a hardware host entity, wherein the central office point of delivery management entity is connected to a further access functionality being realized by means of a plurality of further access nodes that terminate physical subscriber lines serving end users of a further telecommunications network,
• wherein the system is configured such that:
• the central office point of delivery management entity and the hardware host entity exchange configuration and setup information to bring the central office point of delivery instance into operation on the hardware host entity, wherein the hardware host entity comprises a virtualization layer and the central office point of delivery instance is operated as a virtualized central office point of delivery on the hardware host entity, wherein the central office point of delivery instance is operated as a satellite central office point of delivery with respect to the central office point of delivery management entity,
• the central office point of delivery management entity manages the operation of the central office point of delivery instance running on the hardware host entity, the central office point of delivery instance operatively realizing access functionality regarding the end users of the telecommunications network using the plurality of access nodes and the physical subscriber lines thereof, wherein managing, by the central office point of delivery management entity, of the operation of the central office point of delivery instance involves the exchange of operational state information via the virtualization layer, and involves at least one out of the following:
• telemetry and logging functionality, involving monitoring of application and hardware health, quality and/or performance,
• exchange of non-customer control plane information,
• exchange of customer-related control information, involving customer authentication information, connection information, and/or product parameters, wherein user plane traffic bypasses the virtualization layer, wherein the user plane traffic bypassing the virtualization layer are session setup and termination information and/or customer payload.
