Como: An open infrastructure for network monitoring-research agenda
Our idea is to define a per-query accuracy metric and maximize the aggregate accuracy of all query results given the available resources. We argue that in network monitoring it is always possible to regulate the accuracy of a query (that will include the measurement error as well as the timeliness of the results). For a given set of queries we then need to define an aggregate utility function and be able to exercise a fine-grained control over it. To overcome this challenge we need to address two orthogonal sub-challenges. The first has to do with allowing users to post any query to the systems in a secure fashion. The second is about the definition and regulation of queries’ accuracy in a distributed monitoring infrastructure. We now describe the two sub-challenges in detail and introduce our ideas to overcome them.
