Network node, information processing system, and method

摘要

The consistency between an application output destination and a permitted user for an I/O device section is ensured when a user deploys an application for processing and outputting input data onto an entrance node. The entrance node includes an output destination/user table that manages correspondence between an application output destination and a user. The output destination/user table stores information about the output destination used for each user who uses the entrance node. An application deployment management function of a processing section in the entrance node determines whether application deployment can be accepted from a user. To do this, the application deployment management function specifies a user corresponding to the output destination for the application from the output destination/user table and verifies that the user is consistent with a user permitted for an I/O device in the I/O device section used by the application.
