The tests mapped to this layer report the overall health of each of the following BES components/services:

• The BlackBerry Router, which transmits all data to handheld
• The BlackBerry MDS, which provides connectivity between BlackBerry SmartPhones and enterprise applications
• The BlackBerry message-handling services, which handle the mail traffic to and from the handheld device
• The BlackBerry SRP (Server Routing Protocol) host, which provides BES with information related to the location of handheld devices
