Abstract: It is disclosed an originating node (22), a router node (24) and a source node (26), and methods therein for allowing updates of information objects in Information centric networking (ICN). By introducing a field in a request for an update of an information update, where the field comprises validity aspects specifying conditions for which the request is valid, a single request may be treated as a request for a subscription of updates of an information object, and several updates may be communicated as responses to the single request. It is an advantage that these updates may be communicated to a large number of request originating nodes.

Abstract: A networking approach that maintains the benefits of ICN, but that can also be used to implement N-way commit protocols. In one aspect, a method performed by a routing apparatus (104) is provided. In some embodiments, the method includes the routing apparatus (104) receiving a request message (302, 602) transmitted by a requesting apparatus (102), the request message (302, 602) comprising a first content name. The routing apparatus (104) forwards the first request message (302, 602) towards a publishing apparatus (106). After forwarding the first request message (302, 602), the routing apparatus (104) receives, via a network interface (907), a first response message (304, 608) transmitted by the publishing apparatus (106), the first response message (304, 608) comprising the first content name and a second content name. The routing apparatus (104) forwards the first response message (304, 608) towards a requesting apparatus (102) and links the second content name with a network interface identifier for identifying the interface via which the routing apparatus (104) received the first response message (304, 608).

Abstract: An access node (20) of a cellular network receives an information centric networking request of a user equipment (10) for a data object. The access node forwards the information centric networking request to a local gateway (30) associated with the access node (20). The local gateway (30) maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (30). In response to the user equipment (10) moving from a coverage area of the access node (20) to a coverage area of a further access node (21), the access node (20) and the further access node (21) perform a handover procedure. The further access node (21) is associated with a further local gateway (31) maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (31). The handover procedure initiates alignment of the pending interest table and the further pending interest table with respect to at least one entry associated with the user equipment (10).
