This is the back-end system for Zaphod.
NAT64Check consists of three layers:
- Zaphod: the president of the NAT64Check universe
- Front-end: the user interface for scheduling tests and looking up results
- Back-end: the API where tests are dispatched to one or more Trillians
- Trillian: the coordinator of a test-run and master of Marvins
- Marvin: the menial worker performing a part of a test
There are multiple Trillians, each coordinating tests in a part of the world. Each Trillian controls multiple Marvins. Each Marvin is connected to a different kind of network (IPv4-only, NAT64 etc.) to test a website under different circumstances.
There is only one Zaphod, controlling all Trillians.
