TL;DR: In this article, a terminal communicating with a network including a forwarding device(s) for forwarding a packet and a control device for controlling the forwarding devices in accordance with a request from the forwarding device, includes: a communication unit that receives a processing rule indicating that a packet for communicating with first destination is changed so as to communicate with a second destination, from the control device; a storage unit that stores the received processing rule, and a processing unit that in a case of communicating with the network, changes a destination of a packet in accordance to a processing rules that corresponds to the

TL;DR: In this article, a communication system includes a control device, a forwarding node that processes a packet transmitted from a user terminal, and a path control unit that determines path from user terminal to access destination and sets to forwarding node along the path the second processing rule that corresponds to the path.

TL;DR: In this paper, a communication system includes an information acquisition unit that acquires information for determining an isolation level to which a user terminal belongs, from the user terminal, an information storage unit that defines whether or not access is possible to respective access destinations for each isolation level, and an access control unit that causes a forwarding node(s) to implement forwarding or dropping of a packet, in accordance with whether it is possible or not to access to the respective access destination.

TL;DR: In this article, the authors derived authority permission grants/denials associated with each of a plurality of roles (R1, R2,..., Rm) assigned to one subject by inheritance based on a subject assignment associating a role and a subject, and a role hierarchy indicating an inheritance relation between roles.
