Gossiping in chordal rings under the line model
The line model assumes long distance
calls between non neighboring processors. In this sense, the line
model is strongly related to circuit-switched networks, wormhole
routing, optical networks supporting wavelength division
multiplexing, ATM switching, and networks supporting connected mode
routing protocols.
Since the chordal rings are competitors of networks as meshes or
tori because of theirs short diameter and bounded degree, it is of
interest to ask whether they can support intensive communications
(typically all-to-all) as efficiently as these networks. We
propose polynomial algorithms to derive optimal or near optimal
gossip protocols in the chordal ring
Building Regular Registers with Rational Malicious Servers and Anonymous Clients
The paper addresses the problem of emulating a regular register in a synchronous distributed system where clients invoking and operations are anonymous while server processes maintaining the state of the register may be compromised by rational adversaries (i.e., a server might behave as rational malicious Byzantine process). We first model our problem as a Bayesian game between a client and a rational malicious server where the equilibrium depends on the decisions of the malicious server (behave correctly and not be detected by clients vs returning a wrong register value to clients with the risk of being detected and then excluded by the computation). We prove such equilibrium exists and finally we design a protocol implementing the regular register that forces the rational malicious server to behave correctly
