A method for subscription flow, the method comprising: receiving, by a network entity that comprises a device that is part of a messaging hierarchy in a computer network, subscription information from another entity in the network, wherein said subscription information defines a desired scope of published content to which said another entity subscribes; retaining, by the network entity, the subscription information and associated connection information; determining, by the network entity, whether the desired scope is encompassed by a scope of content to which the network entity subscribes; when determined that the desired scope is encompassed by the scope of content to which the network entity subscribes, not propagating the subscription information for the first entity further within the hierarchy; when determined that the desired scope is not encompassed by the scope of content to which the network entity subscribes, then: a) providing, by the network entity, the subscription information to a parent tier when the network entity is determined to have a parent tier; and b) as for lower tier entities that are on a same or lower tier of said hierarchy as said network entity, providing, by the network entity, the subscription information to only ones of the lower tier entities that provides at least a portion of published content that the subscription information indicates; and establishing virtual connections between entities in said computer network based on a data hierarchy for the messaging hierarchy, wherein information embedded within published content defines said data hierarchy, and wherein said published content is content published by one or more publishing entities in the computer network to which one or more subscribing entities subscribe.
