  • Data communication protocol
    Patent number: 9438696
    Abstract: Described is a data communication protocol, in which a client and server negotiate in a manner that does not require the client to retry negotiation when servers are not capable of the client-desired protocol. In one example implementation, the desired protocol is SMB 2.0 or greater. The protocol describes a create command with possibly additional context data attached for built-in extensibility, and a compound command comprising a plurality of related commands or unrelated commands. A multi-channel command requests data transfer on a separate data channel, a signed capability verification may be used to ensure that a secure connection is established, and the protocol provides the ability to transfer extended error data from the server in response to a request.

  • Compounding of HTTP authoring protocol
    Patent number: 7600030
    Abstract: Conventions for extending compounded web authoring methods to a web authoring protocol such as WebDAV. More particularly, a request can be provided with special header information to signify a method compounded with a method indicated by a verb in the request. Techniques for clients and servers to use the web authoring extensions. Extended error handling to allow servers to provider richer web authoring error information to clients.
