Abstract: A service bus system includes: a plurality of first devices each coupled with a client; a plurality of second devices each to perform a service; a first service bus device through which sequences of a session between the first and second devices are communicated, including: a prediction unit to predict one or more other service bus devices through which connection between the first and second devices in a second or later sequence of the session is established; and a transmission unit to transmit information indicating the connection in the first sequence of the session to the one or more other service bus devices predicted; and a second service bus device including: a storage unit to hold the information transmitted from the first service bus device; and a connection unit to establish the connection in the second or later sequence of the session by using the connection information held.

Abstract: A radio terminal equipment includes a route supervision processing section for registering, for each destination address, an address of a radio-relay terminal equipment, which relays datagrams destined for the destination address, into a routing table in accordance with a predetermined dynamic routing protocol, a first transmission processing section for transmitting a datagram to a radio-relay terminal equipment corresponding to the destination address of the datagram in accordance with the routing table, a datagram supervision processing section for receiving the datagram transmitted by the radio-relay terminal equipment corresponding to the destination address of the datagram transmitted by the first transmission section to supervise whether or not the datagram has been relayed, and a second transmission processing section for transmitting, where the received datagram is to be relayed by the terminal equipment itself, the datagram to the radio terminal equipment corresponding to the destination address of
