摘要： A system, apparatus, and method are directed towards selectively combining data into a packet to modify a number of packets transmitted over a network based on a detection of a transaction boundary. If it is determined to concatenate the data, such concatenation may continue until an acknowledgement (ACK) is received, or a predetermined amount of data is concatenated in the packet, or a transaction boundary is detected. If at least one of these conditions is satisfied, concatenation may be inhibited, and the packet may be sent. Concatenation is then re-enabled. In one embodiment, Nagle's algorithm is used for concatenating data into a packet. In one embodiment, an ACK may be sent based on a write completion indicator included within a packet. Receipt of the ACK may disable concatenation.

摘要： A method, system, and apparatus are directed towards selectively concatenating data into a packet to modify a number of packets transmitted over a network based on a combination of network and/or send-queue metrics. In one embodiment, Nagle's algorithm is used for concatenating data into a packet. The concatenation may be selectively enabled based on heuristics applied to the combination of metrics. In one embodiment, the result may indicate that there should be a concatenation, or that data should be sent immediately, or that a current state for whether to concatenate or not should be maintained. The heuristics may include an expert system, decision tree, truth table, function, or the like. The heuristics may be provided by a user, or another computing device. In another embodiment, the concatenation may be enabled based on a conditional probability determined from the combination of metrics.

摘要： A system, apparatus, and method are directed to managing multiple back-end connections for pipelined HTTP communications. A traffic management device is configured to open back-end connections to multiple servers. The traffic management device distributes HTTP requests from a client device across multiple server connections. Instead of buffering the responses to ensure that each are returned in a same order as the requests, the traffic management device throttles a TCP receive window between all of the back-end server connections, but that back-end server connection associated with a first expected response. As each response is sent to the client device, the TCP window for the next back-end server connection is opened. This effectively offloads any significant buffering onto the back-end servers, enabling the traffic management device to return the responses in the same order as the requests.

摘要： A method, system, and apparatus are directed towards enabling access to payload by a third-party sent over an SSL session. The third-party may be a proxy situated between a client and a server. SSL handshake messages are sent between the client and the server to establish the SSL connection. As the SSL handshake messages are routed through the proxy, the proxy may extract data. In addition, one of the client or the server may send another message within, or out-of-band to, the series of SSL handshake message directly to the proxy. The other SSL message may include secret data that the proxy may use to generate a session key for the SSL connection. With the session key, the proxy may receive SSL messages over the SSL connection, modify and/or transpose the payload within the received SSL messages, and/or terminate the SSL connection at the proxy.

摘要： A method, system, and apparatus are directed towards compression of content. A portion of content may be compressed using a compression mode. One or more criteria may be evaluated. Based on the evaluated criteria, a decision is made as to whether to select a different compression mode. If selected, the different compression mode may be used to compress another portion of the content. Additional compression modes may be selected and used to compress the content.

摘要： Adaptive network traffic classification using historical context. Network traffic may be monitored and classified by considering several attributes using packet filters, regular expressions, context-free grammars, rule sets, and/or protocol dissectors, among other means and by applying a variety of techniques such as signature matching and statistical analysis. Unlike static systems, the classification decisions may be reexamined from time to time or after subsequent processing determines that the traffic does not conform to the protocol specification corresponding to the classification decision. Historical context may be used to adjust the classification strategy for similar or related traffic.

摘要： A system and method for capture and resumption of network application sessions in a network system. A transaction may be detected between a client and server that includes application session state information. The session state information may relate to a session between the client and the server. The Application session state information may be recorded in response to the detection of the transaction, and the application session state information may not be deleted according to session information expiration policies (e.g., of the client). User input may be received which requests to review the captured network application session. Correspondingly, a network request comprising captured credentials of the captured session may be generated and forwarded to the server. The network request may be usable to enable resumption of the captured network application session.

摘要： A method, apparatus, and system are directed toward managing network traffic over a plurality of Open Systems Interconnection (OSI) Level 2 switch ports. A network traffic is received over the plurality of OSI Level 2 switch ports. At least a part of the network traffic is categorized into a flow. The categorization may be based on a IP address, an OSI Level 4 port, a protocol type, a Virtual Local Area Network (VLAN) number, or the like, associated with the network traffic. One of the plurality of OSI Level 2 switch ports is selected based on a load-balancing metric. The load-balancing metric may be a priority of the flow, a congestion characteristic, a prediction of a load usage for the flow, a combination thereof, or the like. A frame associated with the flow is sent over the selected one of the plurality of OSI Level 2 switch ports.
