Peer2Peer s*cks, here’s why
Peer2Peer (P2P) is sometimes proposed as an alternative for distributed content delivery. Some CDN’s are built upon P2P technology. P2P vendors, researchers and CDN’s claim that P2P lowers costs. It does. For the content owner. But it raises costs for the network owners. Significantly.
Basically the concept of P2P is that every client can redistribute content to other clients. As a content provider you don’t need to buy servers or traffic. Your audience distributes your content ‘for free’. Ingest the content into the network and let it flow. It is also hard to trace where content is hosted and ingested from. That is why P2P is so popular for (illegal) file sharing services.
