Abstract
A communication system realizes End-to-End communication between communication devices via at least one service function by using Segment Routing IPv6. The communication system executes: transferring a packet received from one of the communication devices at a communication origin of the End-to-End communication, by using an abstracted ID obtained by abstracting a segment ID in a prescribed range determined in advance; and converting, upon receipt of the packet including the abstracted ID, the abstracted ID into an address or a segment ID of a service function instance providing the service function.
