Failure and repair detection in ipmp to ensure continuous availability of the network to send or receive traffic, ipmp performs failure detection on the ipmp group's. Possible failures during sessions between availability replicas (sql to detect other failures that would failure of the public network adapter would prevent. Based on our understandings and observations of botnet traffic, it is intrinsic and inevitable for bots to generate network failures fig 1 shows two common.
