== remsim-server

=== Running

`remsim-server` currently has no command-line arguments. It will bind to
INADDR_ANY and offer the following TCP ports:

* Port 9998 for the inbound control connections from `remsim-client`
  and `remsim-bankd`
* Port 9997 for the RESTful/JSON Web API (role: HTTP server)

It is intended to make these settings (IP addresses, ports) configurable
in future versions.

=== Logging

`remsim-server` currently logs to stdout only, and the logging verbosity
is not yet configurable.  However, as the libosmocore logging framework
is used, extending this is an easy modification.

=== RESTful/JSON Web API

`remsim-server` provides a RESTful/JSON WEB API for application logic
integration.  The purpose of the API is to allow run-time configuration
and monitoring of the entire osmo-remsim system.

The API currently has version 1, and the URL prefix is /api/backend/v1

==== /api/backend/v1/clients

*GET* obtains a JSON list where each element represents one currently
connected `remsim-client`.

No other HTTP operation is implemented.

==== /api/backend/v1/clients/:client_id

*GET* obtains a single JSON object representing one specific currently
connected `remsim-client`.

No other HTTP operation is implemented.

==== /api/backend/v1/bankds

*GET* obtains a JSON list where each element represents one currently
connected `remsim-bankd`.

No other HTTP operation is implemented.

==== /api/backend/v1/bankds/:bank_id

*GET* obtains a single JSON object representing one specific currently
connected `remsim-bankd`.

No other HTTP operation is implemented.

==== /api/backend/v1/slotmaps

*GET* obtains a JSON list where each element represents one provisioned
slot mapping.

*POST* creates a new slot mapping as specified in the JSON syntax
contained in the HTTP body.

No other HTTP operation is implemented.

==== /api/backend/v1/slotmaps/:slotmap_id

*DELETE* deletes a slot mapping by its identifier.  If the mapping is
currently in use, the related bankd is instructed to disconnect the
client from the card.

No other HTTP operation is implemented.

==== /api/backend/v1/global-reset

*POST* performs a global reset of the `remsim-server` state.  This means
all mappings are removed.
