Realtime kernel

摘要

A realtime kernel supports realtime communications between communicants operating on respective network nodes. The realtime kernel handles the complex tasks of connecting to communicants, virtual areas, and other network resources, switching those connections in response to user inputs, and mixing realtime data streams. The realtime kernel enables developers to focus on developing high-level communications functionality instead of low-level plumbing code. The realtime kernel imposes relatively low computational resource requirements so that realtime communications performance can be achieved using a wide range of computing devices and network connections that currently are available.

1. A method of realtime data stream handling, comprising by a local network node:
establishing at least one realtime data stream connection between the local network node and a remote network node; processing at least one realtime data stream sourced by the remote network node over the realtime data stream connection, wherein the processing comprises processing the at least one realtime data stream through one or more realtime data processing operations to produce a resultant data stream; wherein the processing comprises instantiating processing objects ones of which are operable to perform respective ones of the data processing operations, building a directed graph form ones of the instantiated processing objects, and processing the realtime data stream through the directed graph; monitoring the processing; and in response to a determination based on the monitoring that the processing deviates from a performance target, modifying the processing in accordance with a realtime performance targeting routine.
