摘要： In a system where transactions are accelerated with asynchronous writes that require acknowledgements, with pre-acknowledging writes at a source of the writes, a destination-side transaction accelerator includes a queue for queue writes to a destination, at least some of the writes being pre-acknowledged by a source-side transaction accelerator prior to the write completing at the destination, a memory for storing a status of a destination-side queue and possibly other determinants, and logic for signaling to the source-side transaction accelerator with instructions to alter pre-acknowledgement rules to hold off on and pursue pre-acknowledgements based on the destination-side queue status. The rules can take into account adjusting the flow of pre-acknowledged requests or pre-acknowledgements at the sender-side transaction accelerator based at least on the computed logical length.

摘要： A method is provided for establishing a split-terminated secure communication connection between a client and a server. A first network intermediary intercepts a secure communication connection request directed from the client to the server. A second intermediary having a digital certificate in the name of the server (and a corresponding private key) acts in place of the server to establish a first secure communication session with the client, during which it receives a secret from the client for generating the session key. The second intermediary supplies the secret and/or the session key to the first intermediary, which allows the first intermediary to establish follow-on secure communication sessions in which the secret is reused. The second intermediary may also supply the first intermediary with a copy of its certificate so that it can respond to new secure communication requests and, yet further, may also supply a copy of the private key.

摘要： Transaction accelerators can be configured to terminate secure connections. A server-side accelerator intercepts a secure connection request that is from a client and that is directed to a server. The server-side accelerator responds to the secure connection request in place of the server, thereby establishing a secure connection between the client and the server-side accelerator. Alternatively, the server-side accelerator monitors the establishment of a secure connection between the client and the server. After the secure connection has been established, the server-side accelerator forwards security information to a client-side accelerator, enabling the client-side accelerator to assume control of the secure connection. As a result of this arrangement, the client-side accelerator is able to encrypt and decrypt data on the secure connection and accelerate it in cooperation with the server-side accelerator. In a further embodiment, the accelerated traffic between accelerators is carried across the network via another secure connection.

摘要： A network intermediary device such as a transaction accelerator intercepts a client request for a secure communication connection with a server. The intermediary issues a substitute connection request to the server and receives a digital certificate during establishment of a secure communication session between the intermediary and the server. Based on information in the received digital certificate, the intermediary selects an appropriate operational configuration for responding to the client's request. The intermediary consults an ordered list or other collection of digital certificates it possesses, and chooses one having a common name that matches the server's common name. The match may comprise the first matching name, the longest match, the best match, the broadest match (e.g., a certificate having a name that includes one or more wildcard characters), etc. The intermediary then uses the selected certificate (and corresponding private key) to establish a secure communication session with the client.

摘要： Classification of packets into flows is an inherent operation performed by networks that support enhanced services. To support multiple-dimensional packet classification, a packet classification system is provided to select representative bits from a packet to look up a set of rules. The per-flow classification works with a large set of rules, where each rule comprises of multiple fields and also allows fast dynamic variation in the rule set. A lookup process includes a simple and finite set of instructions that can be efficiently implemented as pipelined hardware and support very high packet arrival rates.

摘要： A method and apparatus are provided for split-terminating a secure client-server communication connection, with client authentication. During handshaking between the client and the server, cooperating network intermediaries relay the handshaking messages, without altering the messages. At least one of the intermediaries possesses a private key of the server, and extracts a set of data fields from the handshaking messages, including a Client-Key-Exchange message that can be decrypted with the private key. The intermediary uses the extracted data to compute the client-server session key separate from the client's and the server's similar computation, and may transmit the key to the other intermediary via a secure communication channel. The client and the server thus establish the end-to-end client-server connection, and may authenticate each other, after which the network intermediaries may intercept and optimize the client-server communications transparently to the client and the server.
