Abstract: Provided are methods and systems for multi-caching. The methods and systems provided can enhance network content delivery performance in terms of reduced response time and increased throughput, and can reduce communication overhead by decreasing the amount of data that have to be transmitted over the communication paths.

Abstract: Devices, systems, and methods of improving protocol performance are disclosed. One method includes transmitting a block of frames to another communication device, and upon completion of the transmitting, requesting an acknowledgement of the transmitted block from the another communication device. The method further includes receiving the acknowledgement and adjusting the number of frames in the block based on information from the received acknowledgement.

Abstract: Devices, systems, and methods of improving transport protocol performance in a multi-path environment are disclosed. One network device comprises a transport-layer proxy; and a multi-path traffic distributor coupled to the transport-layer proxy. The transport-layer proxy is configured to receive packets, each associated with a transport-layer connection, from a transport-layer endpoint. The proxy is further configured to deliver at least a portion of the received packets to the multi-path traffic distributor. The multi-path traffic distributor is configured to:assign each of the delivered packets to one of a plurality of data flows, and to transmit each of the delivered packets on an outbound path associated with the assigned data flow.

Abstract: Systems and methods of improving transport protocol performance are disclosed. One exemplary method includes: in a first state, non-linearly increasing a congestion window; in response to the congestion window exceeding a threshold value while in the first state, transitioning to a second state; and in the second state, linearly increasing the congestion window.

Abstract: Systems and methods of network monitoring are disclosed. One exemplary method includes receiving a first packet, creating a filter instance if the first received packet matches a filter template, receiving a second packet, and storing the second received packet if the second received packet matches the created filter instance. The filter instance is based at least partially on the filter template. An exemplary system includes a network interface, a memory, and a processor. The memory stores program code which programs the network monitor device to receive a first packet, create a filter instance if the first received packet matches a filter template, receive a second packet, and store the second received packet if the second received packet matches the created filter instance. The filter instance is based at least partially on the filter template.

Abstract: A system and method for communicating between source and destination transmission and presentation of streaming digital information signals can be uses to optimize performance in the context of the contentions among different dimensions of performance including goodput, throughput, delay, receiver buffer requirements and tolerance to loss and jitter. The system provides ordering segments of information based on a priority associated with each of the segments of the information; managing of flow of the segments into and out of a buffer based on the priority of the segments of information; adjusting a rate at which information is provided to a communication medium; and transmitting the information.

Abstract: Systems and methods for reconfiguring a transport-layer protocol are disclosed. The transport-layer protocol is implemented by a plurality of transport-layer mechanisms. Each transport-layer mechanism resides in a dynamically loadable module and implements a specific area of transport-layer functionality. One method comprises: performing an initial load of a first plurality of transport-layer mechanisms into memory; unloading one of the first plurality of transport-layer mechanisms; and loading at least one transport-layer mechanism different than the first plurality. One system comprises a processor coupled to a local interface; a memory coupled to the local interface; and protocol logic stored in the memory and executable by the processor.

Abstract: Systems and methods for the communication of data over a plurality of parallel communication paths are provided. Embodiments of the parallel communications systems and methods may discover, characterize, and leverage multiplicity of resources in various network elements to provide network applications with a desired communication objective and level of performance. The systems and methods may dynamically adapt to changes in the network resources to continuously provide the desired communication performance.

Abstract: A system and method for transmitting and presenting streaming digital information signals that optimizes performance in the context of goodput, throughput, delay, receiver buffer requirements and tolerance to loss and jitter. The method provides ordering packets of information based on a priority associated with each of the packets; managing the flow of the packets into and out of a buffer; adjusting the rate at which the packets are provided to a communication medium; and transmitting and retransmitting the packets as needed.

Abstract: The techniques according to the present invention can be used to optimize signal transmission according to the quality of service (QOS) required or requested at the receiver/destination/client. Such optimization can take into account actual user requirements, human perception minimum requirement or application specific requirements. Scaling can also be provided based on the size of the network or the number of users on the network. The quality of service requirement seeks to trade off or balance quality, complexity, delay, and data rate. In other words, the QOS techniques of the present invention seeks to minimize delay and maximize throughput. That is, to maximize quality within constraints.
