Intrusion-Tolerant Shared Memory through a P2P Overlay Segmentation
Davi da Silva Böger, Joni Silva Fraga, Eduardo Alchieri, Michelle Silva Wangham · 2012
This paper describes our experience in developing an infrastructure which allows building intrusion-tolerant shared memory for large-scale systems. The infrastructure makes use of a P2P overlay and of the concept of State Machine Replication (SMR). Segmentation is introduced on the overlay key space to allow the use of algorithms for SMR. In this paper we describe the proposed infrastructure in its stratification and corresponding algorithms. An analysis about the algorithms and their costs is also presented.
