In computing, a stateless protocol is a communications protocol in which no session information is retained by the receiver, usually a server. Relevant session data is sent to the receiver by the client in such a way that every packet of information transferred can be understood in isolation, without context information from previous packets in the session. This property of stateless protocols makes them ideal in high volume applications, increasing performance by removing server load caused by retention of session information.
Monitoring latency of a network to manage termination of distributed transactions
InactiveUS7290056B1Reduce in quantityReduce the numberMultiple digital computer combinationsTransmissionStateless protocolFinancial transaction
Described herein is a system for executing distributed transactions. A participant and a coordinator cooperate to execute a distributed transaction, the distributed transaction including a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. The distributed transaction may be terminated when communication between the participant and coordinator regarding the transaction does not occur within a time period. The time period may reflect the time required for a coordinator to send a message and a participant to acknowledge receipt of the message, and the time for the participant to perform operations executed for the transaction. The latency of network traffic between the participant and the coordinator is monitored, and the time periods adjusted accordingly. In addition, the amount of time required for the participant to execute operations for the transaction is monitored, and the time periods adjusted accordingly.

Low latency cacheable media streaming
ActiveUS20110080940A1Lower latencyRaise the possibilityPicture reproducers using cathode ray tubesPicture reproducers with optical-mechanical scanningGroup of picturesCache server
A low latency streaming system provides a stateless protocol between a client and server with reduced latency. The server embeds incremental information in media fragments that eliminates the usage of a typical control channel. In addition, the server provides uniform media fragment responses to media fragment requests, thereby allowing existing Internet cache infrastructure to cache streaming media data. Each fragment has a distinguished Uniform Resource Locator (URL) that allows the fragment to be identified and cached by both Internet cache servers and the client's browser cache. The system reduces latency using various techniques, such as sending fragments that contain less than a full group of pictures (GOP), encoding media without dependencies on subsequent frames, and by allowing clients to request subsequent frames with only information about previous frames.

Service broker for processing data from a data network
InactiveUS7032002B1Multiple digital computer combinationsStore-and-forward switching systemsCommand languageServer appliance
A method and system for communication between server-less computing devices or clients in computers communicating over networks, such as the World Wide Web (WWW) using stateless protocols, e.g., HTTP. In this scheme, there are two classes of clients which can operate independently or can be combined in computers communicating over the network: a) clients that issue commands and request status or data, and b) clients that function as service brokers for providing services and processing commands, updating status and providing specific data—resembleing a server device but without accessible TCP / IP ports. Each service providing device is authenticated, retains a unique identity and establishes a soft state with the globally accessible server or servers. All devices and clients can compile and process a globally common command language established between all communicating network clients. The central server includes a CGI processing program and a database to retain client specific information. The server database represents a collection of queues, each having a client unique identifiable status, pending commands and / or data components. In this scheme, commands and signaling transmitted between the servers and clients utilize standard HTTP protocol semantics and HTML or standard markup language syntax. Clients encapsulate or embed information as parameters passed to HTTP CGI as a set of standard HTTP conversations. A CGI processing program converts, parses or processes each conversation and passes arguments with or without data to queues.

Techniques for increasing efficiency while servicing requests for database services
ActiveUS6950822B1Reduce resource consumptionMultiple digital computer combinationsTransmissionStateless protocolDatabase server
Techniques for servicing requests for database services include maintaining at a database server an available set of one or more database session data structures. Each database session data structure holds information to support one session of one or more requests for database services over a communication connection that persists for one or more communications from one client. A database session data structure in the available set is not associated with any client currently connected to the database server. These techniques allow a database server to more efficiently service more numerous requests for database services, such as generated by communications using a stateless protocol like HTTP.

Application prioritization in a stateless protocol
InactiveUS20040006602A1Multiple digital computer combinationsSecuring communicationTraffic capacityBalancing network
Techniques are disclosed that enable an application to prioritize its traffic in an application-specific manner, such that traffic which is most important to this application can be prioritized over traffic that is less important to this application, where this prioritization information is reflected in differential treatment of the traffic within the network. An application conveys relative priority information for its traffic to a Web proxy or edge server, and this device then consults stored policy information to determine how the traffic should be prioritized in the network. The Web proxy also ensures that usage of network resources is balanced among multiple applications. Cookies are used for transmitting priority information between the edge server and application in an efficient manner.

System and methods for controlling an application
InactiveUS7558861B1Overcomes the complexity of a command-based interfaceProvide convenienceRandom number generatorsMultiprogramming arrangementsCommand-line interfaceStateless protocol
Users of network based software applications typically interact with an application via a command line interface or a menu interface. Conventional voice-driven communication threads rely on a dedicated communication line (connection) to maintain a session context, or state, between a user and an application for the duration of a session. Such state information enables the application to reference a session context for the session duration, and employ the session context to maintain a state from previous atomic messages sent and received between the device and the application. By maintaining and referencing a session context indicative of previous messages, an application identifies an atomic message as corresponding to a particular session context, and employs the session context to process the message within the context, or environment, defined by the previous messages in the session. In this manner, a stateless protocol such as a text messaging protocol is operable to invoke stateful applications from the stateless infrastructure by employing the session context defined by the session of request and response messages.

Simple object access protocol
InactiveUS7146618B1Multiple digital computer combinationsTransmissionObject lifetimeStateless protocol
An application layer protocol is provided on top of HTTP 1.0 / 1.1 to allow for COM Automation objects to be invoked over the Internet through IIS / ISAPI servers. The format essentially encodes the automation object's name, method to invoke, and any [in], [out], [in, out] parameters that the method signature requires, packages them up into a custom MIME type and marshals it to the ISAPI dynamic link library (DLL) on the IIS / HTTP server. There, the ISAPI DLL contains the logic to unpack the SOAP request, parses it, creates the Automation object, invokes the method with the marshaled parameters, and then returns any [out] parameters to the caller / client using the SOAP protocol. It is a stateless protocol, meaning that object lifetimes only extend to one method, and are recreated between multiple calls to the object.

Methods, apparatuses and systems facilitating the support of stateful messaging protocols in web services and other network environments comprising a plurality of distributed control points. The present invention supports Web service protocols, such as SOAP-Conversation, that introduce an element of statefulness into a Web service invocation, ensuring that use of such protocols is enabled and, in some embodiments, enhanced in web services networks implemented by a plurality of distributed control points or routing nodes. As discussed above, a fundamental requirement introduced by stateful protocols is that, once an endpoint initializes stateful data (such as a session, context, or conversation token) in response to a Web service invocation, all subsequent messages associated with that conversation instance or stateful data must be routed to that endpoint. In other words, the consuming applications requiring access to functionality dependent on stateful data must have an affinity for the endpoint on which the state data resides for as long as the dependency persists. The invention provides methods, apparatuses and systems directed to ensuring that the control points implement this affinity. For each stateful conversation, certain embodiments of the present invention maintain a set of routing rules that track the usage of such protocols and make sure sequences of messages that must be sent to the same endpoint are properly dispatched. The present invention can be applied to a variety of web- or application-service network architectures comprising a plurality of distributed control points or routing nodes.
