Transaction accelerator for client-server communications systems

Granted: March 19, 2013
Patent Number: 8402085
Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by…

Connection forwarding

Granted: February 26, 2013
Patent Number: 8386637
Two or more network traffic processors connected with the same LAN and WAN are identified as neighbors. Neighboring network traffic processors cooperate to overcome asymmetric routing, thereby ensuring that related sequences of network traffic are processed by the same network proxy. A network proxy can be included in a network traffic processor or as a standalone unit. A network traffic processor that intercepts a new connection initiation by a client assigns a network proxy to handle…

Selecting proxies from among autodiscovered proxies

Granted: February 19, 2013
Patent Number: 8380825
Network devices include proxies and where multiple proxies are present on a network, they can probe to determine the existence of other proxies. Where more than two proxies are present and thus different proxy pairings are possible, the proxies are programmed to determine which proxies should form a proxy pair. Marked probe packets are used by proxies to discover each other and probing is done such a connection can be eventually formed even if some probe packets fail due to the marking.…

Reliability and availability of distributed servers

Granted: January 29, 2013
Patent Number: 8364815
A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy…

System and method for serving web pages

Granted: December 11, 2012
Patent Number: 8332515
A system is shown that supplies web pages from servers (109 to 116, 301 to 305) to requesting clients (102 to 106) over the Internet (101). Each server is configured to supply web page data to requesting clients. A traffic manager (120) receives request data from browsing clients and selects one of the serving devices for serving web page data. A data manipulation station (125) manipulates request data or web page data. The traffic manager supplies a function call to the data…

Transaction accelerator for client-server communication systems

Granted: November 27, 2012
Patent Number: 8321580
In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to…

Cooperative proxy auto-discovery and connection interception

Granted: November 20, 2012
Patent Number: 8316118
In a network supporting transactions between clients and servers and proxies that are interposable in a network path between at least one client and at least one server, wherein a pair of proxies can modify a packet stream between a client and a server such that packet data from the client to the server is transformed at a client-side proxy of the proxy pair and untransformed at a server-side proxy of proxy pair and such that packet data from the server to the client is transformed at…

Transaction accelerator for client-server communications systems

Granted: November 13, 2012
Patent Number: 8312101
Transactions are accelerated by the transaction handlers by storing segments of data used in the transactions in persistent segment storage accessible to the server side transaction handler and in persistent segment storage accessible to the client side transaction handler. When data is to be sent between the transaction handlers, the sending transaction handler compares the segments of the data to be sent with segments stored in its persistent segment storage and replaces segments of…

Methods and systems for secure communications using a local certification authority

Granted: November 6, 2012
Patent Number: 8307203
A local network traffic processor and an application are resident on a common computer system. The application is configured to trust a server certificate issued by a local network traffic processor, the local network traffic processor operatively being paired with a remote network traffic processor. A proxy server certificate, generated using identification information of a server associated with the remote network traffic processor and signed by the local certification authority, is…

Transaction accelerator for client-server communications systems

Granted: September 18, 2012
Patent Number: 8271688
In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to…

Log structured content addressable deduplicating storage

Granted: September 11, 2012
Patent Number: 8266114
A log structured content addressable deduplicated data storage system may be used to store deduplicated data. Data to be stored is partitioned into data segments. Each unique data segment is associated with a label. The storage system maintains a transaction log. Mutating storage operations are initiated by storing transaction records in the transaction log. Additional transaction records are stored in the log when storage operations are completed. Upon restarting an embodiment of the…

Establishing a split-terminated communication connection through a stateful firewall, with network transparency

Granted: August 28, 2012
Patent Number: 8255544
A method and apparatus are provided for establishing a split-terminated client-server communication connection through a stateful firewall, with network transparency. In an environment in which a pair of network intermediaries is employed to optimize client-server communications, a first intermediary intercepts a client request for a new connection. The first intermediary probes the network for a counterpart near the server, and opens an optimized communication session with a second…

Automatic framing selection

Granted: June 19, 2012
Patent Number: 8204058
Network traffic is monitored and an optimal framing heuristic is automatically determined and applied. Framing heuristics specify different rules for framing network traffic. While a framing heuristic is applied to the network traffic, alternative framing heuristics are speculatively evaluated for the network traffic. The results of these evaluations are used to rank the framing heuristics. The framing heuristic with the best rank is selected for framing subsequent network traffic. Each…

Connection based denial of service detection

Granted: May 29, 2012
Patent Number: 8191136
A system for detecting network intrusions and other conditions in a network is described. The system includes a plurality of collector devices that are disposed to collect data and statistical information on packets that are sent between nodes on a network. An aggregator device is disposed to receive data and statistical information from the plurality of collector devices. The aggregator device produces a connection table that maps each node on the network to a record that stores…

Establishing network connections between transparent network devices

Granted: May 15, 2012
Patent Number: 8180902
Transparent network devices intercept messages from non-transparent network devices that establish a connection. Transparent network devices modify these messages to establish an inner connection with each other.
