How to Receive Network Nodes, Endpoint Nodes, and Attention Messages

摘要

The present invention relates to a network node ( ₁₅ ) comprising at least one communication interface, at least one memory, and at least one processor. At least one processor receives a message of interest from a downstream node ( ₁₄ ) over the at least one communication interface, the message of interest including the name of the requested data object; Determine whether to bid to store the requested data object in the at least one memory; Calculate a bid value; Delivering the interest message to the upstream node ( ₁₆ ) via the at least one communication interface, the interest message including the calculated bid value according to the determination of whether to bid at least; Receiving a data message from the upstream node over the at least one communication interface, the data message comprising the requested data object; Determining from the at least data message whether the network node has won the bid; Store the data object in the at least one memory if the network node has won the bid; And forward the data message to the downstream node via the at least one communication interface.
