Abstract: A communication system constituted by a plurality of nodes connected to each other via a network includes: a first node that receives a publish message for requesting for transmission of an object, from a publisher terminal; and a second node. Each of the nodes from the first node to the second node: has a storage unit in which first routing information is recorded; performs a first routing; and records, in the storage unit, an object ID of the publish message and second routing information. The communication system also includes a third node that receives a subscribe message for requesting for receipt of the object, from a subscriber terminal. Each of the nodes from the third node to the first node: performs a second routing; and records, in the storage unit, an object ID of the subscribe message, and third routing information.

Abstract: A disclosed example is a network system including physical nodes. The network system provides a virtual network system including virtual nodes allocated computer resources of the physical nodes. In a case where the network system performs migration of a first virtual node for executing service using computer resources of a first physical node to a second physical node, the network system creates the communication paths for connecting the second physical node and the neighboring physical nodes on the physical links, starts the service executed by the first virtual node using the computer resources secured by the second physical node, switches communication paths to the created communication paths for switching the virtual links.
