Systems and methods for delivery of opaque objects provided by a content provider to network nodes within a communication network are described. Opaque objects may comprise data objects whose data structure is not natively defined in the network interface and thus have a data type and/or structure that would be unknown to systems of the network. Communication systems may be configured according to embodiments to facilitate delivery of such opaque objects, such as by providing a robust network interface between a content provider system and the network through which network information is provided from the network to the content provider system and/or delivery manifest information for opaque objects is provided from the content provider system to the network.
