This work is also limited to BitTorrent protocol.

(2007)) proposed a mechanism where the helpers need to download only small portions of a file to be “busy” enough for serving other peers in the long term. In addition, the whole design is not generic but is based solely on swarming that is managed by a tracker this limits the potential of the solution to BitTorrent based systems only. While Wong presented a new mechanism for increasing the available bandwidth at the network level, the performance at the client’s side was still in question as the proposed mechanisms did not address the problem of bandwidth stability of a helper peer – which is a major factor for the performance of the download process. It was also shown that the inherent assumption of sufficient altruism in the network without any incentives makes the approach impractical in real world environments (see, e.g. It was shown that this strategy is wasteful because the longer a peer/helper stays in the system, the more pieces it will download, which is unnecessary for helpers to keep their upload bandwidth fully utilized (see, e.g. Its objective was to increase the total amount of available bandwidth in the P2P network, by voluntarily contributing the helper peer’s bandwidth resources. The helper downloads a new piece when the number of unfulfilled pieces is below a certain predetermined limit. To make sure each piece it downloads is uploaded at least u times, a helper keeps track of the number of times each piece has been uploaded and considers a piece unfulfilled if the piece has not been uploaded u times. Thus, helpers can guarantee to upload more than they download and contribute to the system. The helper aims to upload each file piece (portion) it downloads at least u times, where u is a heuristically predetermined number called upload factor.

In his work, which was limited to file sharing based on a swarming mechanism, Wong offered to utilize the free upload capacity of a helper peer for the benefit of client peers, simply by joining helper peers to an existing swarm (See Fig.

The concept of employing helper peers in a P2P networks was first proposed by Wong (see, e.g. We focus on designs that aim to solve the stability problem– as we believe that Helpers will play a crucial role in creating future P2P networks that are competitive with old school’s centralized file hosting and streaming systems.

In the following sections we will survey different implementations of Helper peers for different applications in P2P networks. Helper peers, sometimes named as Feeders or Support peers – peers that do not function as direct consumers or providers of content but are used to collaborate with other peers in the network.
