Multiple SRPs

BlackBerry UEM
enterprise connectivity traffic for
BlackBerry 10
devices includes email, organizer data, and browser network traffic. All of this traffic flows from the
BlackBerry Dispatcher
(one for each
BlackBerry UEM
instance), to the active
BlackBerry Affinity Manager
within the
BlackBerry UEM
domain, to the
BlackBerry Infrastructure
, and then to the device. In the path between the
BlackBerry Affinity Manager
and the
BlackBerry Infrastructure
, network conditions such as latency, packet loss, and packet reordering reduce the rate at which data can be transmitted over a single TCP connection due to the nature of the TCP/IP protocols.
Adding SRPs allows the
BlackBerry Affinity Manager
to establish multiple connections to the
BlackBerry Infrastructure
, known as SRP connections. Each connection must have an SRP ID associated with it. By having multiple connections, you can compensate for these network effects by reducing the amount of data each connection must carry between the
BlackBerry Affinity Manager
and the
BlackBerry Infrastructure
. The
BlackBerry UEM
Configuration Tool helps estimate how many SRP connections you need for your particular domain size and network conditions.
It is a best practice to establish the correct number of SRP connections before you install
BlackBerry UEM
, to allow for a good distribution of
BlackBerry 10
devices across the SRP connections.
BlackBerry 10
devices are statically assigned to the least loaded SRP connection during activation. If an extra SRP connection is added later, new devices are assigned to the new SRP connection when they are activated until the new SRP connection reaches the same load as the other SRP connections.
