BlackBerry SRP and Infrastructure



Description

Research In Motion pioneered push technology with the introduction of the BlackBerry® Enterprise Solution in 1999. The traditional wireless challenges for the Enterprise are security, connectivity to multiple carriers, network latency and privacy.

The BlackBerry SRP Infrastructure faces the internet and listens on IP Port 3101 for connections from BlackBerry Enterprise Servers. Because the customer BES hardware initiates connections, the corporate firewall does NOT require inbound connections, or "holes in the firewall". This design allows quick approval of the security requirements in many organizations. The SRP Infrastructure has inbound connections from tens of thousands of BlackBerry Servers all over the world. Because the BES leaves the connection nailed up continuously, the ability to send Push Notifications to handhelds is very fast, efficient, and reliable.

Both the BES and BlackBerry Handhelds use a minimum of 3DES encryption and all packets passing over-the-air, the internet, or the SRP are already encrypted.

On the other side of the SRP Infrastructure, the SRP design virtualizes connections to many dozens of wireless carriers. The BES users, administrators, and developers do not need to have any concern for which carrier a particular handheld is connected to.

Configuration

When installing a BlackBerry Enterprise Server, you must specify the address of the SRP. For North America, this address is srp.us.blackberry.net. If you are installing a BES outside of the USA, use the RIM lookup utility to get the DNS name of the SRP for your country.
