Internetware is the software system in which various components in open and independent forms implement cross-network interconnections, intercommunications and collaborations in various collaborative methods. Dynamic evolution is an important characteristic of internetware and would lead to system failure when it occurs. So reliability analysis of internetware oriented dynamic evolution is one of the hot research topics. Firstly, the protocol relations of interaction at the interfaces between components and dynamic evolution error propagation reachability of internetware are analyzed, and a generation model of error propagation reachability graph is established. Secondly, in order to solve the problem of state space "explosion", a Markov state transition graph is generated from the error propagation reachability graph, and a Markov-based reliability analysis method for internetware oriented dynamic evolution is proposed. Finally, a case study demonstrates the effectiveness of the proposed method.
