Improving network services resilience through automatic service node configuration generation

Abstract

Network management is facing new challenges with the definition of the future Internet. Among those challenges, the management of network's heterogeneity represents a highly complex problem. The most popular proposals addressing this problem following RFC 3139 guidelines, translate from mid-level independent representations to the network's services and devices heterogeneous management interfaces and data models. However, the translation mechanisms defined so far, apart from being highly complex, perform inefficient mapping operations and depend on the administrator manual intervention to maintain and validate the mappings. The MiNSC framework was created to overcome the limitations of those translation mechanisms, providing a mid-level management abstraction based on the association of standard network management interfaces and standard network management information models. Supported through a distributed model, the MiNSC architecture improves network services resilience to node failures. This paper describes this new integrated management approach, illustrating and experimenting its functionalities for the DNS service configuration management, capable of automatic node's configuration replication and redeployment aiming to improve the service's resilience.
