Problems solved by technology

However, the requesting node (i.e., the requester) may still be required to perform a different iteration to obtain the sought data object, or may not receive the sought data object fast enough, or may not receive the sought data object at all ( i.e. an unwanted data object is received instead)

Embodiment Construction

[0055] figure 1 Embodiments of the network node and the requesting node and further network nodes 21 , 23 and 25 of the invention are shown in . The network node 1 comprises a set of communication interfaces 3 , a processor 5 and a memory 7 . The processor 5 is configured to receive interest messages on a communication interface in the set of communication interfaces 3 . Interest messages include a request for a data object and metadata. The metadata specifies one or more criteria to be used to select a subset of items. Processor 5 is further configured to determine whether there is a match between the requested data object and the plurality of items, and if a match has been determined to exist, to select a subset of the plurality of items by applying the one or more criteria. At least one of the one or more criteria is a specified preference for at least one of: factual attributes of the plurality of items, usage data related to the plurality of items, usage data related t...

Abstract

A network node (1) is configured to receive an interest message comprising a request for a data object and metadata. The metadata specifies one or more criteria for selecting a subset of a plurality of items. The network node is further configured to determine whether there is a match between the requested data object and a plurality of items (e.g. from a CS or FIB) and select a subset of the plurality of items by applying the one or more criteria if the match has been determined to exist. At least one of the criteria is a preference specified for at least one of: factual properties of the plurality of items, usage data related to the plurality of items, usage data related to the at least one communication interface, an effort to obtain data from another network node, and a position in a range specified in the interest message.

Description

technical field [0001] The invention relates to a network node for receiving Interest messages and a requesting node for transmitting Interest messages. [0002] The invention further relates to a method of receiving an Interest message and a method of transmitting an Interest message. [0003] The invention also relates to a computer program product causing a computer system to carry out such a method. Background technique [0004] Information-centric networking (ICN) is a new networking paradigm that aims to evolve the current Internet infrastructure from a host-oriented system to a data-oriented system. Instead of addressing endpoints via IP addresses, in the ICN the data itself is addressed. By breaking data into chunks and giving each chunk a unique and hierarchical name, ICN allows clients to ask the network for a given named data object without worrying about where that data is located / stored. One of the benefits of naming data is the ability of each intermediate...
