NLSR Management

===============

NLSR Management provides:

- command to add(advertise) routes to name prefix list

- command to remove(withdraw) routes to name prefix list

## 1. Control Commands

### Add a name prefix

### command-verb: advertise

This command adds a name prefix to the name prefix list. This command can be accepted on ```ndn:/localhost/nlsr/routeUpdate``` prefix.

### Control Parameters

- Name (required)

### Remove a name prefix

### command-verb: withdraw

This command removes a name prefix from the name prefix list. This command can be accepted on ```ndn:/localhost/nlsr/routeUpdate``` prefix.

### Control Parameters

- Name (required)

## 2. Request format

NLSR control commands are signed interests, whose name has the following form: ```/<prefix>/<management-module>/<command-verb>/<control-parameters>/<signed-interests-components>```

- ```<prefix>``` is ```/localhost/nlsr ```. Each individual command may specify additional prefixes under which that command could be accepted.

- ```<management-module> ```is the name of management module to which the command needs to be dispatched. For example, the name of the management module of the task I’m doing now would be ```prefixUpdate```.

- ```<command-verb>``` is the command to be executed. For this task this would be either ```withdraw``` or ```advertise```.

- <control-parameters> is a ControlParameters TLV block wrapped in a NameComponent.

- <signed-interest-components> are four additional components defined by [ndn-cxx:SignedInterest|Signed Interest] spec.

So, putting everything together, the complete name of a command interest would be ```localhost/nlsr/routeUpdate/advertise``` or ```localhost/nlsr/routeUpdate/withdraw```

## 3. Response Format

A response from the command interface is a Data that matches the request Interest. The payload of this Data is a ControlResponse block.
