A system for processing triggering rules in SIP event notification filters, including an XPath processor configured to collect a set of XPath expressions from at least one trigger of at least one SIP event notification filter of at least one subscribers in a set of subscribers who are subscribed to state information of a resource, and create a merged finite state automaton having a plurality of nodes and transitions that collectively represent the combination of the XPath expressions, and a streaming parser configured to parse previously-published state information of the resource and newly-published state information of the resource, and stream parsing events of the parsed information to the XPath processor, where the XPath processor is configured to employ the automaton to perform a streaming evaluation of the XPath expressions in parallel to determine which nodes of the parsed information satisfies any of the XPath expressions represented by the automaton.

Parallel processing of triggering rules in SIP event notification filters

A multi-protocol authentication and authorization system including a request interceptor configured to receive from a requestor a first request using a first transport protocol and a second request using a second transport protocol, and an authenticator for validating a digest received from the requestor, where the request interceptor is configured to authenticate the requestor if the digest is valid and if at least one multi-protocol criterion applied to the requests is met.

Multi-protocol authentication and authorization in computer network environments

A method for providing SSO authentication when accessing non-SSO-compliant applications, the method including forwarding a user name and a password received from a non-SSO-compliant application to an SSO proxy, encapsulating the user name and password in a request to access a protected application, authenticating the user name and password responsive to the request using SSO authentication, and generating an SSO token if said authentication step is successful.
