We propose the notion of collaborative peer groups',defined as peer-to-peer overlay networks with controlledmembership and multiway communication primitives thatoffer well-defined semantics. Peers join such groups subjectto symmetric acceptance, typically based on functionalcommonalities and, optionally, group-specific authentication.Collaborative peer group networks share the sameproperties as other peer-to-peer networks, including full decentralization,symmetric abilities, and dynamism. In addition,however, an extensible set of multiway communicationprimitives, especially appropriate for such peer groups, isprovided and supports operations such as reliable messagedelivery to proximal group members or a subset thereof,message aggregation from peers, and discovery of peerssupporting specific functional attributes. Based on severalcurrent and emerging application scenarios, we motivateand present the proposed collaborative peer group model,outline the group management architecture, and describethe initial set of communication primitives to be supported.A discussion of the toolkit development methodology andpreliminary experiences concludes the paper.
