Abstract: An extended Web services description language (WSDL) is provided to allow for the merging of call flow XML with the interface description. This is accomplished through additional WSDL bindings for operations that associate an operation with segments or message points within the call flow. In addition, the extension to WSDL defines a set of interactions that provide additional semantics for how the operation interacts with the call flow. These interactions capture the interaction points between the WSDL. The WSDL interfaces that are created may be used for outbound interactions (i.e. initiated through Web services from some event within the call flow) or for the usual inbound request response. An additional lifecycle listener interface is used to convey different binding points between an enhanced converged Web service processing engine and a converged application implementation of the WSDL.

Abstract: A mechanism for performing dynamic request routing based on broadcast source request information is provided. Each processor chip in the system may use a synchronized heartbeat signal it generates to provide source request information to each of the other processor chips in the system. The source request information identifies the number of active source requests sent by the processor chip that originated the heartbeat signal. The source request information from each of the processor chips in the system may be used by the processor chips in determining optimal routing paths for data from a source processor chip to a destination processor chip. As a result, the congestion of data for processing at each of the processor chips along each possible routing path may be taken into account when selecting to which processor chip to forward data.
