Operation and architecture of a central office point of delivery within a broadband access network of a telecommunications network

A system for operation of a central office point of delivery within a broadband access network of a telecommunications network and/or for execution of network attachment tasks and/or further functional or configuration tasks within the central office point of delivery, the system comprising:

• the central office point of delivery;
• and
• the broadband access network;
• wherein the central office point of delivery and/or the broadband access network comprises:
• access network facing nodes;
• and
• a control function and/or a switching fabric and/or service edge nodes;
• wherein the execution of the network attachment tasks and/or the further functional or configuration tasks within the central office point of delivery involves using an execution state database as well as stateless execution service functionalities being assigned to different execution stages realized within the central office point of delivery, and a message bus connecting the different execution stages, wherein the execution stages comprise at least an access stage, a processing stage, and a device stage, wherein the execution service functionalities—in order to process or execute the network attachment tasks and/or the further functional or configuration tasks—generate and consume messages on and from the message bus;
• wherein a first execution service functionality assigned to or part of the access stage is configured to receive a trigger request regarding a network attachment task and/or a further functional or configuration task, and generate, in response to receiving the trigger request at least a first message on the message bus;
• wherein a second execution service functionality assigned to or part of the processing stage is configured to consume the first message on the message bus, and in response to consuming the first message generate at least a second message on the message bus;
• and
• wherein a third execution service functionality assigned to or part of the device stage is configured to consume the second message on the message bus, and in response to consuming the second message, configure the control function and/or the switching fabric and/or the access network facing nodes and/or the service edge nodes.

A non-transitory computer-readable medium having processor-executable instructions stored thereon for operation of a central office point of delivery within a broadband access network of a telecommunications network and/or for execution of network attachment tasks and/or further functional or configuration tasks within the central office point of delivery,

• wherein the central office point of delivery and/or the broadband access network comprises
• access network facing nodes, and
• a control function and/or a switching fabric and/or service edge nodes,
• wherein execution of the network attachment tasks and/or the further functional or configuration tasks within the central office point of delivery involves using an execution state database as well as stateless execution service functionalities being assigned to different execution stages realized within the central office point of delivery, and a message bus connecting the different execution stages,
• wherein the execution stages comprise at least an access stage, a processing stage, and a device stage,
• wherein the execution service functionalities—in order to process or execute the network attachment tasks and/or the further functional or configuration tasks—generate and consume messages on and from the message bus,
• wherein the processor-executable instructions, when executed, facilitate performance of the following steps:
• in a first step, receiving, by a first execution service functionality assigned to or part of the access stage, a trigger request regarding a network attachment task and/or a further functional or configuration task, and in response to receiving the trigger request, generating, by the first execution service functionality, at least a first message on the message bus;
• in a second step, consuming, by a second execution service functionality assigned to or part of the processing stage, the first message on the message bus, and in response to consuming the first message, generating, by the second execution service functionality, at least a second message on the message bus;
• and
• in a third step, consuming, by a third execution service functionality assigned to or part of the device stage, the second message on the message bus, and in response to consuming the second message, configuring, by the third execution service functionality, the control function and/or the switching fabric and/or the access network facing nodes and/or the service edge nodes.
