Method and apparatus for NDN (Named Data Networking) based message delivery in publish and subscribe system using Rendezvous

摘要

The present invention relates to a publishing and subscription (pub/sub) system based on Named Data Networking (NDN), which includes a publisher node that issues event data for a topic, one or more subscriber nodes that receive event data, and a rendezvous node. However, the subscription request data is converted into an interest packet in the NDN router and transmitted to the rendezvous node, and the subscriber node receives the event data by one of multicast push, unicast push, or fetch from the rendezvous node. This is disclosed.
