Abstract
Provided are a control apparatus, a control method, and a program capable of designing efficient end-to-end monitoring in a VPN infrastructure. The control apparatus according to the present invention controls end-to-end monitoring in a VPN infrastructure in which communications of a plurality of users are superimposed. The control apparatus includes a user end databasethat stores information about customer edge apparatuses (CEs) for each of the users, each of the CEs serving as a monitoring end of end-to-end monitoring, an end-to-end path databasethat stores information about all links included in a path between the CEs, and an end-to-end monitoring management unitthat sets a monitoring path for end-to-end monitoring to between the CEs so that combinations of the monitoring path passing through each of the links are coprime.
