Endpoints

Transports carry message data for endpoints. Administrators configure endpoint implementation and transport usage in the realm.

  • Configuration Model
    This overarching model serves as a framework for understanding the concepts and tasks of configuring a realm. Refer back to this model as you read the topics that follow.
  • Endpoints
    An endpoint is an abstraction that represents a set of publishers and subscribers in communicating programs.
  • Abilities
    An endpoint has four communication abilities. A separate aspect of the API embodies each of these abilities. The following table summarizes the four abilities.
  • Implementation: Endpoints (Micro)
    Administrators arrange transports to implement endpoints.
  • Implementation: Application (Macro)
    Administrators view an application program both as an executable program, and also as a set of process instances of that program, running on one or more host computers. Arranging process instances on various host computers is one of the administrator’s responsibilities.
  • Administrative Requirements
    Administrators must coordinate with application developers to properly configure and deploy applications.
  • Administrative Options
    When configuring endpoint implementation, administrative choices affect transmission characteristics for the application. Consider these factors when optimizing overall performance.
  • Sample Configuration 1: tibsendex and tibrecvex
    This first example illustrates basic concepts in configuring transports and endpoint implementation, namely: binding a transport to carry an ability, configuring connectors, joining endpoints through a common transport, dividing message streams over separate transports.
  • Sample Configuration 2: tibrequest and tibreply
    This second example illustrates additional concepts in configuring transports and endpoint implementation, namely: binding a transport to carry several abilities; two-way message traffic; and connection-oriented transports with connecting and listening ends.
