> A [Peer Sampling
> Service|http://infoscience.epfl.ch/record/83409/files/neg--1184036295all.pdf]
> is a module that provides a partial view of a cluster to dependent modules. A
> node's partial view, combined with all other nodes' partial views, combine to
> create a fully-connected mesh over the cluster. This way, a given node does
> not need to have direct connections to every other node in the cluster, and
> can be much more efficient in terms of resource management as well as
> information dissemination. Peer Sampling Services by their nature must be
> self-healing and self-balancing to maintain the fully-connected mesh.
> I propose we use an algorithm based on
> [HyParView|http://asc.di.fct.unl.pt/~jleitao/pdf/dsn07-leitao.pdf], which is
> a concrete algorithm for a Peer Sampling Service. HyParView has a clearly
> defined protocol, and is reasonably simple to implement.
