Operation of a broadband access network of a telecommunications network

A method for operation of a telecommunications network, comprising:

• transmitting, by a first leaf network node of a plurality of leaf network nodes of a switching fabric of a central office point of delivery of a broadband access network of the telecommunications network, a traffic load information message regarding a current load situation of the first leaf network node to a central power management entity or functionality of a central office point of delivery;
• transmitting, by the central power management entity or functionality, a session transfer request message to a session management entity or functionality of the central office point of delivery, wherein the session transfer request message corresponds to requesting permission to carry over one or more sessions handled by the first leaf network node to a second leaf network node of the plurality of leaf network nodes;
• transmitting, by the session management entity or functionality, a session transfer answer message to the central power management entity or functionality, wherein the session transfer answer message corresponds to the session transfer request message, and wherein the first leaf network node is controlled such that one or more sessions previously handled by the first leaf network node are carried over to the second leaf network node;
• and
• transmitting, by the central power management entity or functionality, a traffic load execution message to the first leaf network node, wherein the traffic load execution message is for controlling the first leaf network node such that the first leaf network node is switched off or switched to a stand-by state or switched to an energy-saving state;
• wherein the central office point of delivery is located between a core network of the telecommunications network and a customer's premises, wherein the central office point of delivery is connected to the customer's premises via a first line termination node of a plurality of line termination nodes of the broadband access network, and wherein the plurality of spine network nodes route traffic from the customer's premises towards the core network;
• wherein the first line termination node is connected via dual-homed links to both the first leaf network node and the second leaf network node, wherein the first leaf network node hosts a first service edge functionality terminating a first connection between the first leaf network node and the first line termination node, and the second leaf network node hosts a second service edge functionality terminating a second connection between the second leaf network node and the first line termination node.

One or more non-transitory computer-readable mediums having processor-executable instructions stored thereon for operation of a telecommunications network, wherein the processor-executable instructions, when executed, facilitate performance of the following:

• transmitting, by a first leaf network node of a plurality of leaf network nodes of a switching fabric of a central office point of delivery of a broadband access network of the telecommunications network, a traffic load information message regarding a current load situation of the first leaf network node to a central power management entity or functionality of a central office point of delivery;
• transmitting, by the central power management entity or functionality, a session transfer request message to a session management entity or functionality of the central office point of delivery, wherein the session transfer request message corresponds to requesting permission to carry over one or more sessions handled by the first leaf network node to a second leaf network node of the plurality of leaf network nodes;
• transmitting, by the session management entity or functionality, a session transfer answer message to the central power management entity or functionality, wherein the session transfer answer message corresponds to the session transfer request message, and wherein the first leaf network node is controlled such that one or more sessions previously handled by the first leaf network node are carried over to the second leaf network node;
• and
• transmitting, by the central power management entity or functionality, a traffic load execution message to the first leaf network node, wherein the traffic load execution message is for controlling the first leaf network node such that the first leaf network node is switched off or switched to a stand-by state or switched to an energy-saving state;
• wherein the central office point of delivery is located between a core network of the telecommunications network and a customer's premises, wherein the central office point of delivery is connected to the customer's premises via a first line termination node of a plurality of line termination nodes of the broadband access network, and wherein the plurality of spine network nodes route traffic from the customer's premises towards the core network;
• wherein the first line termination node is connected via dual-homed links to both the first leaf network node and the second leaf network node, wherein the first leaf network node hosts a first service edge functionality terminating a first connection between the first leaf network node and the first line termination node, and the second leaf network node hosts a second service edge functionality terminating a second connection between the second leaf network node and the first line termination node.
