Publish/Subscribe (PubSub) is an established communication paradigm where senders do not communicate information directly to intended receivers but rely instead on a service that mediates the relationship between senders and receivers. Pubsub is a communication model that is considered for a number of application domains, in particular it is considered for Content Centric Networking (CCN), also called Information Centric Networking (ICN). MPEG appears to have sufficient technology for PubSub available. Requirements and use cases for the proposed MAF are found in N14180 Publish/Subscribe Application Format (PSAF).
