How a BlackBerry Infrastructure Works

How a BlackBerry Infrastructure Works

Components of a BlackBerry Infrastructure

BlackBerry Enterprise Server
BlackBerry Enterprise Server, also known as BES, manages flow of traffic between application servers and handhelds via BlackBerry's SRP network. The primary feature of BES from IT administrator perspective is ability to have granular control over BlackBerry devices. It allows capability to remotely deploy applications, wipe devices, lock devices and enforce security polices. BES delivers most of the functionality on the market to effectively manage fleet of BlackBerry devices.
BlackBerry Handheld Devices
You will find BlackBerry devices everywhere you go—at the mall, business meetings and on the belt of executives. BlackBerry devices allow executives to have information at their finger tips. When BlackBerry Handheld is part of  BlackBerry Infrastructure, functionality is endless. It allows real time push email, calendar sync, notes sync, tasks sync and support for third party applications.
Messaging Servers
Messaging Servers are a major part of BlackBerry Infrastructure. Microsoft Exchange Server is the most popular messaging server used in BlackBerry Infrastructure. BES also supports IBM Lotus Domino and Novell GroupWise as messaging servers. IT administrators must ensure that BlackBerry Enterprise Server can access messaging servers at all time to allow synchronization of data to BlackBerry devices.
Internet and Rim's SRP Network
BES must connect through the Internet and Rim's SRP Network to communicate with BlackBerry handheld. IT administrators usually do not have control over those networks but we can make sure our BES can talk to the internet and RIM's SRP Network.
How data flows in BackBerry Infrastructure

1. BES picks up a new email message from Exchange Server in real-time.
2. BES connects to RIM's SRP network--srp.blackberry.net on port 3101 via Internet.
3. BlackBerry device is identified by its PIN and new email message is delivered.
