Group Membership for Peer-to-Peer Communication
نویسندگان
چکیده
This paper studies the problem of maintaining eventual consistent group membership without any synchrony assumption inside an unbounded group G of processes that varies over the time (processes may join and leave the group). Eventual consistency means that if at any time all group membership changes cease, processes will converge in a finite time to a single consistent view. Due to the lack of any synchrony assumption, this specification is well suited to large scale peer to peer environments. The paper also presents two impossibility results and two eventual group membership implementations. Last but not least, pointing out a circularity problem, the paper also shows the impossibility of implementing eventual group membership without the existence of a special peer inside the group.

SCAMP: Peer-to-Peer Lightweight Membership Service for Large-Scale Group Communication
Gossip-based protocols have received considerable attention for broadcast applications due to their attractive scalability and reliability properties. The reliability of probabilistic gossip schemes studied so far depends on each user having knowledge of the global membership and choosing gossip targets uniformly at random. The requirement of global knowledge is undesirable in largescale distri...
متن کاملPeer-to-Peer Membership Management for Gossip-Based Protocols
Gossip-based protocols for group communication have attractive scalability and reliability properties. The probabilistic gossip schemes studied so far typically assume that each group member has full knowledge of the global membership and chooses gossip targets uniformly at random. The requirement of global knowledge impairs their applicability to very large-scale groups. In this paper, we pres...

متن کاملIdentity-Based Access Control for Ad Hoc Groups
The proliferation of group-centric computing and communication motivates the need for mechanisms to provide group access control. Group access control includes mechanisms for admission as well as revocation/eviction of group members. Particularly in ad hoc groups, such as peer-to-peer (P2P) systems and mobile ad hoc networks (MANETs), secure group admission is needed to bootstrap other group se...
