Abstract: 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.

Abstract: A pervasive realtime framework supports the execution of realtime software applications with high-level functions that significantly reduce the effort and time needed to develop realtime software applications in a new operating environment paradigm in which realtime connections between network nodes are pervasive. The pervasive realtime framework handles the complex tasks of connecting to communicants, virtual areas, and other network resources, as well as switching those connections in response to user inputs and thereby enables software application developers to focus on developing high-level realtime software application functionality.

Abstract: A graphical user interface is displayed. The graphical user interface includes at least one communication control for managing communications with other network nodes and at least one browser control for navigating to different network resource addresses. Human perceptible realtime output is generated from realtime communication data relating to a realtime communication session with at least one other client network node. In the process of generating of at least some of the human perceptible realtime output, operation of the client network node is managed based on at least one performance target. In the graphical user interface, a graphical representation of a network resource identified in connection with the browser control is displayed.

Abstract: In association with a virtual area, a first network connection is established with a first network node present in the virtual area and a second network connection is established with a second network node present in the virtual area. Based on stream routing instructions, a stream router is created between the first network node and the second network node. The stream router includes a directed graph of processing elements operable to receive network data, process the received network data, and output the processed network data. On the first network connection, an input data stream derived from output data generated by the first network node is received in association with the virtual area. The input data stream is processed through the stream router to produce an output data stream. On the second network connection, the output data stream is sent to the second network node.

Abstract: In order to capture additional network address information that potentially is useful for establishing peer-to-peer connections, client nodes collect network address information from one another. In some examples, the client nodes perform their own independent asymmetric discovery for network addresses that may be sent to a server node for distribution to other client nodes and used to establish peer-to-peer connections between client nodes. In this way, the client nodes are able to obtain network address information that otherwise might not be discoverable by the sever node and thereby increase the number of direct peer connections, improve the robustness of the session establishment process, and reduce the network address collection and peer node matchmaking burdens on the server node.

Abstract: A stream transport protocol supports realtime network communications between communicants operating on respective network nodes. The stream transport protocol supports remote management of client communication sessions, including provisioning of each pair of client network nodes with a respective session definition defining a respective peer-to-peer session over a network connection between the constituent client network nodes of the pair. The stream transport protocol has 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.
