PeerCache

Peer Cache is a technique that Internet providers allows the through file sharing resulting traffic to reduce. PeerCache is supported by Kazaa and eMule , for example .

principle

During the process, a small part of a file to be downloaded is transferred to a server specially provided by the provider . Other clients that need the same part now load it directly from the PeerCache server instead of conventionally from other participants in the file sharing network. The volume of data traffic between the various providers is reduced in this way and the costs incurred are consequently reduced. The advantage for the clients is usually a significantly higher download speed.

distribution

PeerCache has not been able to establish itself in the past because only very few providers support the technology. One reason for this is presumably the fear that this could be seen by critics as targeted support for file sharing. Some providers have already done away with their PeerCache servers.

Some eMule mods support the web cache technique, which is a very similar approach. However, this differs from PeerCache in that it does not require a specially set up server, but uses the provider's existing proxy server . However, more and more providers are also doing away with these servers.

Emergence

In 2001, Kazaa co-developer Niklas Zennström and his team founded Joltid and developed various peer-to-peer technologies. Including the PeerCache. However, a number of providers shied away from using this technology, as they feared they could be prosecuted for complicity.
