The present invention provides a registration management method capable of suppressing influence of data file forwarding load upon processing, and suitable for application to for example VNF Package on-boarding. A data file required for registration is placed in advance on a side of a management apparatus that performs registration processing, and at a registration stage, a registration request is made to the management apparatus by specifying the data file placed on the management apparatus side.

Data file registration management system, method, management apparatus, and recording medium

A system, which is connectable to a first apparatus capable of data communication using a data communication protocol via a network where each session is managed by a session management protocol, includes: a connecting section which, if ID about the first apparatus exists in a storing section when a start instruction is received from the first apparatus, registers ID about a session corresponding to the start instruction in association with the ID about the first apparatus, and establishes a path enabling data communication for the first apparatus in the network using the session management protocol; and a providing section which, upon receiving the ID about the session from a second apparatus, transmits confirmation information according to the result of confirmation about whether the ID about the first apparatus is in association with the ID about the session.
