A method, system, an apparatus are directed towards selectively prefetching content over a network. A request for a content object is received. The content object may comprise a link to another content object. A cachability measure for the link may be determined based on whether a plurality of previous requests for the link returned the other content object, an annotation in a link map, a probability of traversing the link, a network metric, or the like. A prefetchability measure for the link may be determined based on the cachability measure and/or another factor relating to the link. The other factor may be an annotation of the link indicating that caching the other content object will cause a related object to be uncachable. Based on the prefetchability measure, the other content object is selectively prefetched for subsequent provisioning and/or display.

Layer-7 application layer message (“message”) classification is disclosed. A network traffic management device (“NTMD”) receives incoming messages over a first TCP/IP connection from a first network for transmission to a second network. Before transmitting the incoming messages onto the second network, however, the NTMD classifies the incoming messages according to some criteria, such as by assigning one or more priorities to the messages. The NTMD transmits the classified messages in the order of their message classification. Where the classification is priority based, first priority messages are transmitted over second priority messages, and so forth, for example.

A method, computer readable medium, and system for enhancing TCP communications includes transmitting a payload fragment for each of one or more of packets. A determination of which of the one or more packets to complete and reorder is made and a sequence in a completion fragment for one or more of the packets is adjusted based on the determination. One or more of the completion fragments are transmitted based on the determining to reassemble one or more of the transmitted payload fragments with one or more of the transmitted completion fragments based on the determination and adjustment.

A method, system, and apparatus are directed towards selectively compressing data for transmission over a network. In one embodiment, a sending network device and receiving network device negotiates different compression modes to communicate data between them. An initial compression mode may be selected based on a network bandwidth. The sending network device then reads data, and compresses using the selected compression mode. The compressed data may then be written out. Ratios of compression and the write times are then employed to selectively adjust the compression mode for subsequent data compressions. In one embodiment, a compression ratio is also employed to determine whether to employ the selected compression mode, or to reduce the level of compression by using a different compression mode. The receiving network device having received information about the selected compression mode, then employs that compression mode to decompress the received data.

A method, computer readable, and apparatus for read-ahead prediction of subsequent requests to send data between a client coupled to a server via a network includes receiving at a traffic management device a request for a part of at least one of a data file and metadata. The traffic management device selects from two or more of a sequential prediction engine, an expert prediction engine and a learning prediction engine to predict a read-ahead of the at least one of the data file and metadata. One or more additional read-ahead parts of the at least one of the data file and metadata are determined with the traffic management device based on the selecting.

A system, non-transitory machine readable medium and method of delayed packetization of data packets is disclosed. The system and method includes requesting authorization from a QoS queue to transmit an intended data packet over a network, wherein the authorization request is sent from an application module of a transmitting network device. The system and method includes receiving from the QoS queue a transmission order to transmit the intended data packet at a future time. The system and method includes packetizing the intended data packet in accordance with the transmission order at the future time. The system and method includes transmitting the packetized data packet over a network to a receiving network device.

A system, method, and apparatus are directed towards identifying adaptive length segments of redundant data for encoding a data structure. Initial boundaries are identified for an input matching segment within input data and for a candidate store matching segment in a synchronized store. The data prior to and after the boundaries are compared to identify matching data. As matching data is identified, at least one of the boundaries of the matching segments is revised. An encoded representation of the resulting input matching segment is then generated based in part on pointers and offsets into the synchronized store. A data structure is generated based on the encoded representation and unmatched portion, which is sent to a receiver. The receiver uses the data structure to extract matching data from the synchronized store, and together with the unmatched input data in the data structure, reconstruct the input data.
