摘要： A System for providing communications over a communications network includes a communications interface and processor. The communications interface communicates over the communications network. The processor directs a communications scheduler to determine at least one metric for a path within the communications network. The processor also selects a data flow for the path and determines whether to transmit a packet in the selected data flow based on the at least one metric. The processor then directs a communications protocol handler to generate the packet for the selected data flow.

摘要： A method and apparatus are described for controlling connection admission for a connection request in a network. A first estimator estimates an equivalent cell rate (ECR) based on description of the connection request. The description includes a booking factor. A second estimator estimates a measured utilization factor for admitted connections in the network using measurements of data streams arriving at queues. A controller is coupled to the first and second estimators to generate an admission decision for the connection request based on the estimated ECR and the estimated measured utilization factor.

摘要： A system for processing packets includes a communications interface and a processor. A communications interface receives a packet between a source and a destination. The processor identifies a flow between the source and the destination based on the packet. The processor determines whether some of packet data of the packet matches to storage data in storage using hashes. The processor then stores the packet data in a block of memory in the storage based on the flow and if the packet data does not match the storage data.

摘要： Systems and methods for pre-fetching of data in a memory are provided. By pre-fetching stored data from a slower memory into a faster memory, the amount of time required for data retrieval and/or processing may be reduced. First, data is received and pre-scanned to generate a sample fingerprint. Fingerprints stored in a faster memory that are similar to the sample fingerprint are identified. Data stored in the slower memory associated with the identified stored fingerprints is copied into the faster memory. The copied data may be compared to the received data. Various embodiments may be included in a network memory architecture to allow for faster data matching and instruction generation in a central appliance.
