METHOD FOR AN IMPROVED OPERATION OF A BROADBAND ACCESS NETWORK OF A TELECOMMUNICATIONS NETWORK AND/OR FOR AN IMPROVED AND/OR MORE RELIABLE OPERATION OF THE BROADBAND ACCESS NETWORK, BROADBAND ACCESS NETWORK OR TELECOMMUNICATIONS NETWORK, AND SYSTEM, PROGRAM AND COMPUTER-READABLE MEDIUM

The invention relates to a method for an improved operation of a broadband access network of a telecommunications network and/or for an improved and/or more reliable operation of the broadband access network, the broadband access network comprising a central office point of delivery with a plurality of service edge network nodes, each one of the service edge network nodes realizing at least one service edge instance or functionality, terminating a customer communication link towards a customer premises equipment or an access node,wherein a first service edge network node and a second service edge network node comprises, respectively, a forwarding hardware part or module, and a control hardware part or module, wherein the at least one service edge instance or functionality, realized within or by the first service edge network node and being operational at a point in time, corresponds to a state information, at or for that point in time, both in the forwarding hardware part or module, and in the control hardware part or module of the first service edge network node,wherein in order for an improved and/or more reliable operation of the central office point of delivery, the method comprises the following steps:-- in a first step, the state information regarding the at least one service edge instance or functionality realized within or by the first service edge network node is continuously synced at least to the control hardware part or module of the second service edge network node,-- in a second step, subsequent to the first step and in case of failure of the first service edge network node, the second service edge network node realizes the at least one service edge instance or functionality - previously realized within or by the first service edge network node - by means of using the continuously synced state information.
