In this example, if a remote upgrade attempt fails, the device retries the upgrade in
30 minutes, then again after one more hour, then in two hours. If it still fails, it
subsequently retries every four to five hours, until it succeeds.
Profile Rules
The ATA provides multiple remote configuration profile parameters (Profile_Rule*).
This means that each resync operation can retrieve multiple files, potentially
managed by different servers.
In the simplest scenario, the device resyncs periodically to a single profile on a
central server, which updates all pertinent internal parameters. Alternatively, the
profile can be split between different files. One file is common for all of these ATAs
in a deployment, while a separate file is provided that is unique for each account.
Encryption keys and certificate information could be supplied by still another
profile, stored on a separate server.
Whenever a resync operation is due, the ATA evaluates the four Profile_Rule*
parameters in sequence:
1. Profile_Rule
2. Profile_Rule_B
3. Profile_Rule_C
4. Profile_Rule_D
Each evaluation can result in a profile being retrieved from a remote provisioning
server, possibly updating some number of internal parameters. If an evaluation
fails, the resync sequence is interrupted, and is retried again from the beginning
specified by the Resync_Error_Retry_Delay parameter (seconds). If all evaluations
succeed, the device waits for the second specified by the Resync_Periodic
parameter, and then performs a resync again.
The contents of each Profile_Rule* parameter consist of a set of alternatives. The
alternatives are separated by the | (pipe) character. Each alternative consists of a
conditional expression, an assignment expression, a profile URL, and any
associated URL options. All these components are optional within each alternative.
The following are the valid combinations, and the order in which they must appear,
if present:
[ conditional-expr ] [ assignment-expr ] [[ options ] URL ]
