# README #

icwmp_bulkdatad is an implementation of The HTTP bulk data collection mechanism which is an extended feature of CPE and other agents implementing TR-069(CWMP) or TR-369(USP), defined by the Broadband Forum. It provides a means by which an Auto-Configuration Server (ACS), or USP Controller, can configure an agent to periodically send a JSON or CSV formatted set of Device information to an HTTP server running a data collection application.

## Configuration File ##

The icwmp_bulkdatad UCI configuration is located in **'/etc/config/cwmp\_bulkdata'**, and contains 4 sections: **bulkdata**, **profile**, **profile\_parameter** and **profile\_http\_request\_uri\_parameter**.

```
config bulkdata 'bulkdata'
	option enable '0'
	option log_level '3'

config profile
	option profile_id '1'
	option enable '0'
	option csv_encoding_row_time_stamp 'unix'
	option json_encoding_report_time_stamp 'unix'
	option http_retry_minimum_wait_interval '5'
	option http_retry_interval_multiplier '2000'

config profile_parameter
	option profile_id '1'
	option name ''
	option reference ''

config profile_http_request_uri_parameter
	option profile_id '1'
	option name ''
	option reference ''
```
