BlackBerry Dispatcher
The BlackBerry Dispatcher handles traffic to the BlackBerry Infrastructure. It compresses/decompresses and
encrypts/decrypts wireless data. The BlackBerry Dispatcher handles all internal Service Routing Protocol (SRP)
connections from the BlackBerry Messaging Agent and also manages communication from the BlackBerry MDS
Connection Service, the BlackBerry Synchronization Service, the BlackBerry Policy Service, and the BlackBerry
Collaboration Service to the BlackBerry Infrastructure. These components connect to the BlackBerry Dispatcher
through specific ports and communicate with the BlackBerry Infrastructure through the BlackBerry Router using a
unique SRP identifier that the BlackBerry Dispatcher establishes.
BlackBerry Messaging Agent
The BlackBerry Messaging Agent handles BlackBerry Synchronization Service traffic, including contacts, tasks,
memos, message settings, and message filters. The BlackBerry Messaging Agent also has a mechanism for
wireless calendar initialization before wireless calendar synchronization is enabled. This mechanism is used to
initially synchronize the BlackBerry device and the Microsoft Exchange message store, enabling wireless
synchronization to occur. Each BlackBerry Messaging Agent owns a unique internal SRP identifier that connects to
the BlackBerry Dispatcher.
The BlackBerry Messaging Agent also handles all Microsoft Exchange-related traffic using Messaging Application
Programming Interface (MAPI) and Collaboration Data Objects (CDO).
