Network-Wide Rollback Scheme for Fast Recovery from Operator Errors Toward Dependable Network

摘要：

Network failures may have a major impact on our society.There are many possible causes of network failures,of which the most significant is operator errors.Consequently,the development of new network management schemes to tackle operator errors is important.We have already proposed a basic idea of a new network-wide rollback scheme to tackle operator errors.In the proposed scheme,we introduce a server to manage historical versions of sets of device configuration.An operator rolls back a set of device configuration via the server when the operator detects a network failure.In this paper,we present a detail of the network-wide rollback scheme.In addition,we provide three rollback procedures,and implement a prototype system to evaluate their rollback time.The proposed scheme will serve for fast recovery from operator errors,as the minimum rollback time is about 41 seconds,when 50 routers are rolled back.
