# Rotonda



The composable, programmable BGP Engine

The current version of Rotonda allows you to open BGP and BMP sessions and

collect incoming routes from many peers into a in-memory database, modeled as

a Routing Information Base (RIB). It also supports importing routes from MRT

files into this database. Conditions for accepting incoming routes and sending

messages to log files or a MQTT stream can be created using filters with the

`Roto` programming language. The RIB can be queried through an HTTP/JSON

API.

Future versions of Rotonda will support an on-disk database, using external

datasets in filters, reading routes from Kafka streams, and more.

Read the [documentation](https://rotonda.docs.nlnetlabs.nl) to find out how to

install and use Rotonda.

> `Rotonda` is under active development and features are added regularly.

> The APIs, the configuration and the `Roto` syntax may change between

> 0.x versions.

## GOALS

#### Modularity

   Rotonda applications are built by combining units into a pipeline through

   which BGP data will flow. You can filter, and store the BGP data along

   the way, and create signals based on it to send to other applications. We

   aim for units to be hot-swappable, i.e. they can be added and removed in a

   *running* Rotonda application.

   Rotonda offers units to create BGP and BMP sessions, Routing Information

   Bases (RIBs), and more.

#### Flexibility

   The behaviour of the units can be modeled by using a small, fun programming

   language called `Roto`, that we created to combine flexibility and

   ease-of-use. Right now, `Roto` is used define filters that run in the hot

   path of the Rotonda pipeline. It's our goal to integrate filter definition,

   configuration syntax, and query syntax into `Roto` scripts in one place.

   Modifying, versioning and provisioning of your `Roto` scripts should be

   as straight forward as possible.

#### Tailored Performance

   Rotonda aims to offer units that perform the same task, but with different

   performance characteristics, so that you can optimize for your needs, be it

   a high-volume, low latency installation or a small installation in a

   constraint environment.

#### Observability

   All Rotonda units will have their own finely-grained logging capabilities,

   and some have built-in queryable JSON API interfaces to give information

   about their current state and content through Rotonda’s built-in HTTPS

   server. Signals can be sent to other applications. Moreover, Rotonda aims

   to offer true observability by allowing the user to trace BMP/BGP packets

   start-to-end through the whole pipeline.

##### Storage Persistence

   By default a Rotonda application stores all the data that you want to

   collect in memory. It should be possible to configure parts to persist

   to another storage location, such as files or a database. Whether you put

   RIBs to files or in a database, you can should still be able to query it

   transparently with `Roto`.

#### External Data Sources

   `Roto` filter units should be able to make decisions based on real-time

   external data sources. Similarly filter units should be ahlt to make

   decisions based on data present in multiple RIBs. External data sources

   can be, among others, files, databases or even a RIB backed by an RTR

   connection.

#### Robustness & Scalability

   Multiple Rotonda instances should be able to synchronize or shard data via

   a binary protocol, that we dubbed `rotoro`.

#### Security & Safety

   Rotonda applications will be able to use data provided by the RPKI through

   connections with tools like Routinator and Krill. Besides that, Rotonda

   supports BGPsec out of the box. Again, no patching or recompiling required.
