Ecma International 2011 35 CSTA Service Definition ModelCSTA services specified in ECMA-269 are modeled as a request/response interaction.Typically, one entity requests that a particular operation be performed; the other entity attempts to perform theoperation and res
13、ponds to the requestor.5.1 Request/Response InteractionsCSTA services consist of the following types of request/response interactions: Services which specify a response in case of success or failure. The protocol description for these servicesincludes a response element that represents the success (
14、i.e. positive acknowledgement). In case ofservice failure, a fault element is used to provide the failure information (i.e. negative acknowledgement). Services which only specify a response in case of failure. The protocol description for these services do notinclude a response element. A fault elem
15、ent is used to provide the failure information (i.e. negativeacknowledgement).For CSTA event reports, no response is generated.5.2 Request/Response Protocol RequirementsThis Standard specifies CSTA-specific XML-encoded content for messages that are sent across a CSTAService boundary. Typically this
16、CSTA-specific XML is enveloped by a request/response protocol that providesa mechanism for correlating a CSTA request with a CSTA response, manages faults, defines headerinformation, etc.This Standard does not mandate that a specific request/response protocol be used. However, this Standardprovides
17、examples of how the CSTA-specific XML can be used with several industry request/responseprotocols and transports such as SOAP (Simple Object Access Protocol), HTTP, and TCP. These examplesare provided beginning in Annex H.5.3 Cross Referencing of Event ReportsThe Monitor Cross Reference Identifier i
