Provide efficient, stable and secure file distribution and image acceleration

based on p2p technology to be the best practice and

standard solution in cloud native architectures.



## Introduction



Dragonfly is an open source P2P-based file distribution and

image acceleration system. It is hosted by the

Cloud Native Computing Foundation ([CNCF](https://cncf.io/)) as

an Incubating Level Project.

Its goal is to tackle all distribution problems in cloud native architectures.

Currently Dragonfly focuses on being:



- **Simple**: Well-defined user-facing API (HTTP), non-invasive to all container engines;

- **Efficient**: Seed peer support, P2P based file distribution to save enterprise bandwidth;

- **Intelligent**: Host-level speed limit, intelligent flow control due to host detection;

- **Secure**: Block transmission encryption, HTTPS connection support.



## Architecture



![alt][arch]



**Manager:** Maintain the relationship between each P2P cluster, dynamic configuration management and RBAC.

It also includes a front-end console, which is convenient for users to visually operate the cluster.



**Scheduler:** Select the optimal download parent peer for the download peer. Exceptions control Dfdaemon's back-to-source.



**Seed Peer**: Dfdaemon turns on the Seed Peer mode can be used as

a back-to-source download peer in a P2P cluster,

which is the root peer for download in the entire cluster.



**Peer**: Deploy with dfdaemon, based on the C/S architecture, it provides the `dfget` command download tool,

and the `dfget daemon` running daemon to provide task download capabilities.
