Podmailing: how does it work?

This page explains how Podmailing works and solves issues such as unlimited file size, asynchronous delivery and working around firewalls.

The Podmailing Network mixes two kinds of networks: Peer-To-Peer and Centralized. Our main innovation is our solution to mix both systems to benefit from the advantages of both, without suffering from their drawbacks.

  • Peer-To-Peer: data moves directly between the PCs of the sender and his recipients.
  • P2P connections can be very efficient and they reduce the bandwidth cost dramatically for popular files. All P2P connections between Podmailing users conform to the BitTorrent protocol. For more details on BitTorrent and Podmailing, visit this page: How to use torrents with Podmailing.

  • Centralized: data is relayed by our servers, using our online storage and bandwidth.
  • Centralized servers enable a high quality of service. They guarantee that files can always be delivered, even if the sender and the recipients are not online at the same time, or if their connections are blocked by routers or firewalls.

Direct P2P

The large file can be copied directly between 2 PCs.

Large file transferred directly using P2P

Swarming P2P

Numerous recipients can participate
in delivering the large file to each other.

Large file transferred by the P2P swarm

Hybrid P2P

Pure Peer-To-Peer is too limited
when it comes to asynchronous delivery:

Pure P2P cannot deliver the file if the sender is not online

How can you receive the file if its sender is offline?
Podmailing lets you receive the file anytime,
even if the sender is offline:

The Podmailing infrastructure delivers the file if the sender is offline

And even when the sender is online,
our servers participate in delivering the large file even more rapidly:

The Podmailing infrastructure participates in delivering
the large file more rapidly, even around firewalls:

Beyond Podmailing: network interoperability

Podmailing proposes an open solution,
designed to interoperate with other networks:
