Service Broker Routing and Networking

Service Broker communications are designed around reliable, asynchronous message delivery.

Service Broker uses the authentication features SQL Server provides to help protect against

unauthorized access to a service. To help protect message data, Service Broker lets you encrypt

messages that leave the instance.

Communication between two applications occurs through messages. When an application

sends messages, Service Broker locates a route for the service and transmits the message to

the network address that is specified by the route.

Service Broker communicates the status of a conversation to an application through messages.

Service Broker indicates errors, the end of a conversation, and timer events by sending a

message to the service. Like all messages, these messages are associated with a specific

conversation.

Messages from Service Broker and messages from the other side of the conversation arrive and

are processed in the same way. By using the same programming model to process all

messages, you simplify application development. This also lets Service Broker applications be

redeployed without changes to application code.
