A system for performing assurance of at least one network element in a network, the system comprising: at least one pacemaker, wherein the at least one pacemaker is a virtual machine in communication with a path to the at least one network element in the network, the at least one pacemaker configured to selectively provide an atomic workload to the path; a configuration analysis microservice in communication with the at least one pacemaker, the configuration analysis microservice is configured to provide a policy to the at least one pacemaker for application of the atomic workload and monitor a pulse from the atomic workload on the path.

Network service assurance system

A controller node in a network implementing software defined networking (SDN) proactively detects network overload conditions in a target node and subsequently prevents the conditions from developing by launching a new virtual network node. The detection and prevention are based on the determination of a probability of failure of the target node as a weighted function of information from the target node and probabilities of failure of related nodes.
