Abstract: Systems and methods are described for streaming multimedia data from a client to a server using HyperText Transfer Protocol (HTTP). A session is initiated with a header that identifies a content length header that is a maximum allowed by the server, regardless of the actual length of the data to be streamed. If a firewall or proxy server limits access to the server, the content length of the data is specified to be about an amount of data that can be streamed to the server in one minute. If more data remains to be streamed when an amount of data approximating the content length has been streamed, a continuing streaming session is requested and subsequent data is streamed to the server in the continuing streaming session. The process repeats until all data has been streamed.

Abstract: Various computing components (such as devices, operating environments, and processes) may communicate by exchanging instances of a data collection, such as a class or data structure. However, the definition of the data collection may evolve to specify different numbers, types, properties, and orderings of the items in the data collection, and it may be difficult to verify the structure and contents of an instance received from another component and possibly of a different version. This difficulty may be mitigated by exchanging versioning information about the instance (e.g., as part of the communications wire protocol) and by allocating the converting such that the sender may downconvert to earlier versions requested by a recipient, while the recipient may upconvert to later versions than a version provided by a sender. These techniques may promote the accuracy and consistency of information exchange among many components that operate on different versions of the data collection.

Abstract: A client computer hosts a virtual private network tool to establish a virtual private network connection with a remote network. Upon startup, the virtual private network tool collects critical network information for the client computer, and sends this critical network information to an address assignment server in the remote network. The address assignment server compares the critical network information with a pool of available addresses in the remote network, and assigns addresses for use by the client computer that do not conflict with the addresses for local resources. The address assignment server also provides routing information for resources in the remote network to the virtual private network tool. The virtual private network tool will postpone loading this routing information into the routing tables of the client computer until the client computer requests access to a specific resource in the remote network.

Abstract: A method and system for caching HTTP POST requested content using standard caching rules associated with HTTP GET requests are disclosed. When a POST request is received, it is transformed into a GET request with an identifying tag. The identifying tag includes an index value that is unique to the POST request and is based on the POST request's URL and payload. When the POST request has not been encountered before the POST request's URL and payload is stored in a data store. The client then receives a redirect response including the GET request with the identifying tag that it uses to request the data. When the ensuing GET request with the identifying tag is received it is determined if the requested content has been cached. If so, the cached content is returned to the client. Otherwise, the original POST request is recreated and sent to the origin server to retrieve the content. The returned content is sent to the client and is cached using the GET request with the identifying tag.

One sequence number per batch is stored by the identity module and is used to decide whether the sequence number received is accepted or rejected.

Abstract: The invention is directed to techniques for managing access to data available from a data access device using a network switching protocol to manage content requests from clients. A data communications device receives a request for content from a client. The data communications device, such as a network switch, exchanges signals using the network switching protocol with one or more data access devices, such as a web cache. The data communications device can then select one data access device to provide the requested content to the client based, for example, on load balancing considerations. The data communications device sends a data transfer approval signal to the selected data access device. The selected data access device establishes a connection with the client using information, such as the client's network address, provided by the signals. The selected data access device then bypasses the data communications device and sends the requested content to the client.

Abstract: The present invention extends to methods, systems, and computer program products for establishing and maintaining membership within a federation infrastructure. A joining node submits a join message to an existing federation infrastructure. The federation infrastructure routes the join message to a processing node. The processing node facilitates identification of predecessor, successor, neighborhood, and routing nodes (for the joining node) within a ring of nodes. The joining node exchanges messages with identified nodes to obtain state information for the identified nodes and other nodes within the ring. Nodes periodically exchange state information, including state information for other nodes, such that state information for the ring is efficiently propagated to all nodes in the ring even when communication between some nodes is lost. Instance IDs, phase values, and freshness values are used to determine when state information is stale and/or is to be updated.
