Abstract: A network has a plurality of edge nodes (7a, 7b, 7c, 7d) and core nodes (3a, 3b, 3c) for carrying flows of data from an ingress gateway (7a, 7b, 7c, 7d) to an egress gateway (7a, 7b, 7c, 7d) along a path of core nodes. For any given path in the network work from an ingress node to an egress node, the number of flows is controlled. When network congestion occurs, the egress gateway (7a, 7b, 7c, 7d) provides an indication of the level of network congestion. Terminating flows is disruptive and therefore the ingress gateway (7a, 7b, 7c, 7d) can mark other flows with a congestion marker and send them to the egress gateway (7a, 7b, 7c, 7d). These marked flows are routed by the core and egress gateway (7a, 7b, 7c, 7d) but ignored for calculating network congestion. When the network congestion is alleviated, the marked flows can be un-marked and treated as normal flows, hence the network avoids unnecessary flow termination.

Abstract: The Fair-Ordering Service delivers action messages to the server as soon as it is feasible. Because action messages from different players exhibit different reaction times with respect to an update message, the Fair-Ordering Service executed at the server dynamically enforces a sufficient waiting period on each action message to guarantee the fair processing of all action messages. The Fair-Ordering Service takes into consideration delayed and out-of-order action messages. When action messages corresponding to multiple update messages are interleaved, the Fair-Ordering Service matches the action message to the appropriate update message by maintaining a window of update messages and using the reaction times for an action message for each of the update messages in the window. This enables state changes at the game server to be performed with fairness to all the players. The Fair-Ordering Service is based on a framework that uses a proxy architecture.

Abstract: The present solution is directed towards systems and methods to more efficiently control a flow of a data stream traversing at least one intermediary on a network between a client and a server. A sender transmits a first message, comprising a first value of a bandwidth between the first intermediary and a second intermediary determined by the sender, to a first intermediary. The first intermediary establishes a next value of the bandwidth between the first intermediary and the second intermediary. The sender receives from the first intermediary responsive to the first message a second message comprising the established next value of the bandwidth between the first intermediary and the second intermediary. A data transfer manager of the sender, responsive to the second message determines a size of a portion of data queued for transmission to transmit to the first intermediary and a time for transmitting the portion of data queued.

Additionally, the present invention utilizes a stride map, so the audio subsystem knows how many samples to skip in order to reach the next sample frame. The present invention can be used for handling received packets as well as forming packets to send over a bus.
