Abstract: This patent document describes technology for providing real-time messaging and entity update services in a distributed proxy server network, such as a CDN. Uses include distributing real-time notifications about updates to data stored in and delivered by the network, with both high efficiency and locality of latency. The technology can be integrated into conventional caching proxy servers providing HTTP services, thereby leveraging their existing footprint in the Internet, their existing overlay network topologies and architectures, and their integration with existing traffic management components.

Abstract: A proxy server is augmented with the capability of taking transient possession of a received entity for purposes of serving consuming devices. This capability supplements destination forwarding and/or origin server transactions performed by the proxy server. This capability enables several entity transfer modes, including a rendezvous service, in which the proxy server can (if invoked by a client) fulfill a client's request with an entity that the proxy server receives from a producing device contemporaneous with (or shortly after) the request for that entity. It also enables server-to-server transfers with synchronous or asynchronous destination forwarding behavior. It also enables a mode in which clients can request different representations of entities, e.g., from either the near-channel (e.g., the version stored at the proxy server) or a far-channel (e.g., at origin server).
