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.
