Routing Contracts
SimplexDatagramRouter • SessionMode = SessionMode.Allowed • AsyncPattern = true • IsOneWay = true • IInputChannel -> IOutputChannel
ISimplexSessionRouter
IRequestReplyRouter
• SessionMode = SessionMode.Required • AsyncPattern = true • IsOneWay = true • IInputSessionChannel -> IOutputSessionChannel
• SessionMode = SessionMode.Allowed • AsyncPattern = true • IReplyChannel -> IRequestChannel
IDuplexSessionRouter • SessionMode=SessionMo de.Required • CallbackContract=typeof( ISimplexSession) • AsyncPattern = true • IsOneWay = true • TransactionFlow(Transact ionFlowOption.Allowed) • IDuplexSessionChannel
Virtual Endpoint • Scenario: • I want to expose a virtual endpoint so that my consumers aren’t aware of the actual endpoint. • Why? • Flexibility. I can change my service without affecting my clients. I am also free to modify the flight path of the message or the message itself based on external logic or events.

Multicast Messaging • Scenario: • I want to expose a virtual endpoint so that my consumers aren’t aware of the actual endpoints and I want multiple services to receive a copy of the message.
• Why? • Multiple services may be interested in a message or event (subscribers). In more sophisticated scenarios, transformation and routing rules might be applied to determine recipients dynamically.

High Availability • Scenario: • I want to ensure that a redundant service(s) is available in the event that a service goes down. • Why? • Services can come and go. Providing a back up service or list of services to distribute workload and provide high availability is key to a robust service-oriented architecture.
