The Webpush proposal of the Internet Engineering Task Force is a simple protocol using HTTP version 2 to deliver realtime events, such as incoming calls or messages, which can be delivered (or “pushed”) in a timely fashion. The protocol consolidates all real-time events into a single session which ensures more efficient use of network and radio resources. A single service consolidates all events, distributing those events to applications as they arrive. This requires just one session, avoiding duplicated overhead costs.
