Load balancing and dynamic control of multiple data streams in a network

Available bandwidth utilization during transfer of large files over a TCP / IP network is improved by load balancing data streams and dynamically controlling the number of data streams utilized. A determination is made of the optimum number of data streams for a particular data file transfer in the early stage of transmission. An initial number of data streams, which is one unless otherwise specified or determined, is used to transmit one or more file segments, each on a different data stream, immediately followed by a second initial number of data streams, which is at least two greater than the initial number of data streams, is used to transmit another portion of the large data file. During each transmission, individual and aggregate transmission bandwidths are determined. Responsive to a determination that the latest aggregate transmission bandwidth is significantly different from the previous aggregate transmission bandwidth, the number of data streams is modified.

System and method for lowering proxy bandwidth utilization

A hybrid peer-to-peer network that lowers proxy bandwidth utilization is provided. The peer-to-peer network includes peer nodes, a proxy server, and one or more guest nodes. To initiate a transfer of digital content residing on a peer node, a requesting node, which may be another peer node or a guest node, sends an HTTP request to the proxy server. The proxy server determines whether the requested digital content is bandwidth rich content such as digital images, video, or audio. If so, the proxy server generates a URL for the digital content and sends an HTTP redirect message. The requesting node then generates a second HTTP request based on the HTTP redirect message and sends the second HTTP request to the peer node. In response, the peer node generates an HTTP response including the requested digital content and sends the HTTP response to the requesting node.

Backpressure mechanism for switching fabric

Roughly described, a packet switching fabric contains a separate queue scheduler for each combination of an input module and a fabric output port. The schedulers may also be specific to a single class of service. Each queue scheduler schedules its packets without regard to state of other input queues and without regard to packets destined for other output ports. In an aspect, the fabric manages per-flow bandwidth utilization of output port bandwidth capacity by monitoring the same and asserting backpressure toward the queue scheduler for any thread that is exceeding its bandwidth allocation. In another aspect, a switching fabric uses leaky buckets to apply backpressure in response to overutilization of downstream port capacity by particular subflows. In another aspect, a switching fabric includes a cascaded backpressure scheme.
