Why Adapters?Adapters provide transparent connection to external channel.

Messages are routed though the bus controlled by the process management.

ESB also provide various checks, validations, conversions.

Control Event and Bulk Data are transferred over segregated channel.



TIBCO Rendezvous provides decentralized and distributive notification service. There are no centralrepositories for message storage.

Rendezvous client/daemon will connect to each others with auto-discovery when new client/daemon join thenetwork. When sender talks to recipient beyond the same network, the messages are passed through theRendezvous routers, and reach the destination.

Router finds the least cost path to relay the messages. RV using Subject-Based addressing for messagingsending and receiving.

BPM – Business Process ManagementThe business workflow compose the orchestration layer on ESB

Knowledge of business application model usually resides with businessanalysts. Business requirements and definitions are owned by businessanalysts.

Business applications are composite of services. SOA abstract the interfacelayer, which allow business stakeholder directly involved in workflow designwithout bothered on detailed technology.

Business Process

BPM can be an event producer, generating events that represents situations of the business process.

BPM can be an event consumer, reacting to the derived events generated by event processing system.

Event processing node (Agent ) can be composited as types of service components in event processingnetwork.

Event Processing Agent is the node where events are digested, transformed, translated, enriched. It also actsas producer to emit derived events.

Elements: Event Producer, Event Consumer, Event Processing Agent, Event Type, Event Context, Event State

The event processing agent can composite sub-event processing network inside.

Mission to on boarding spacecraft

Challenging in Rendezvous MissionComplexities: Activity control and eventsare operated in dimensions of time andspace, factors including position,velocity, attitude, angular rates

Security: Access Control, collisionavoidance

Synchronization with work/rest cycle in

the timeline; Communication betweenamong space and ground has linkconstraints , delay caused by satelliterelay.

Fault tolerance and thrust errorshandling

Test: Verification and validation withinonly simulating environment. Production

environment is critically available onmission execution. It is disaster whenmission failed
