## 2. Request format
28 2 Muktadir Chowdhury
NLSR control commands are signed interests, whose name has the following form: ```/<prefix>/<management-module>/<command-verb>/<control-parameters>/<signed-interests-components>```
29
30
- ```<prefix>``` is ```/localhost/nlsr ```. Each individual command may specify additional prefixes under which that command could be accepted.
31 13 Muktadir Chowdhury
- ```<management-module> ```is the name of management module to which the command needs to be dispatched. For example, the name of the management module in this case would be ```prefix-update```.
32
- ```<command-verb>``` is the command to be executed. For this case this would be either ```withdraw``` or ```advertise```.
33 14 Muktadir Chowdhury
- ```<control-parameters>``` is a ControlParameters TLV block wrapped in a NameComponent.
34
- ```<signed-interest-components>``` are four additional components defined by [ndn-cxx:SignedInterest|Signed Interest] spec.
35 13 Muktadir Chowdhury
So, putting everything together, the complete name of a command interest would be ```localhost/nlsr/prefix-update/advertise``` or ```localhost/nlsr/prefix-update/withdraw```
