Abstract: A method for establishment of a service path within the central office point of delivery within a broadband access network of a telecommunications network. The method to establish the service path includes: in a first step, identity information of the at least one network termination node is transmitted to the first line termination node, in a second step, subsequent to the first step, the identity information of the at least one network termination node is transmitted to the at least one repository node, and in a third step, subsequent to the second step, a first service edge node of the plurality of service edge nodes is selected or determined, based on the identity information of the at least one network termination node, and the service path for the at least one network termination node is thereby established.

Abstract: A method for enhanced use of a switching fabric within a central office point of delivery of a broadband access network of a telecommunications network includes: transporting data packets to or from a specific remote access node using a pseudo wire, wherein the pseudo wire spans at least the specific remote access node and the switching fabric. Using the pseudo wire comprises using first header label information for a data packet to be received by the specific remote access node and using second header label information for a data packet sent from the specific remote access node. Segment routing of the data packets is used involving third header label information for the data packet to be received by the specific remote access node and involving fourth header label information for the data packet sent from the specific remote access node.

Abstract: A method for handling of multicast data streams within a broadband access network of a telecommunications network includes: a specific service edge node receiving a join request message from or through a specific customer premises equipment; an activation request message being transmitted, by the specific service edge node, to a multicast controller node within the broadband access network; and the multicast controller node generating and/or replicating multicast data stream-related data packets and injecting these multicast data stream-related data packets, using a corresponding session identifier information, into a point-to-point-protocol connection or tunneling protocol connection between the specific service edge node and the specific customer premises equipment.
