Abstract: The claimed subject matter provides late network binding functionality to network or web-based applications or services. An application gateway component exposes generic interfaces for different types of network applications allowing client application developers to utilize generic functionality. Client applications can invoke the generic interfaces, at which point the application gateway component can determine contextual information related to the end user. Using the contextual information, the application gateway component can perform late network binding to a network or web-based application or service by generating and transmitting a request thereto based at least in part on the generic interface invocation and user context. The contextual information can include explicit binding information or data that can be utilized to determine or infer binding preferences.

Abstract: The present invention routes an application request to at least one of a plurality of sites in a packet data network. Session Initiation Protocol (SIP) messages that establish initial dialogs and SIP messages that are stand-alone requests are sent from a call session control function system to a SIP application load distribution system. The SIP application load distribution system routes a SIP message to at least one destination site, based at least in part on user-defined local state data and a user-defined application load distribution policy. Local state data is sent from a plurality of sites to an application management and health checking system. Local state data may be sent autonomously from the plurality of sites. Local state data may also be sent from the plurality of sites in response to a request issued by the application management and health checking system.
