FIELD WIRELESS SYSTEM
First Claim
1. A field wireless system comprising:
- a system manager that manages a wireless network including wireless field devices; and
a backbone router that performs wireless communication with the wireless field devices, whereinthe system manager comprises;
a network configuration collection unit that collects a connection configuration of the wireless network; and
a path selection unit that selects relay paths for each of the wireless field devices that is a destination of a packet, based on the connection configuration that has been collected, andthe backbone router comprises;
a relay information storage unit that stores the relay paths that have been selected; and
a packet processing unit that replicates packets, each of which is destined for each of the wireless field devices, by the number of the relay paths that have been stored, the packet processing unit storing information indicating a different relay path in each of the packets that have been replicated.

Abstract
A field wireless system may include a system manager that manages a wireless network including wireless field devices, and a backbone router that performs wireless communication with the wireless field devices. The system manager may include a network configuration collection unit that collects a connection configuration of the wireless network, and a path selection unit that selects relay paths for each of the wireless field devices that is a destination of a packet, based on the collected connection configuration. The backbone router may include a relay information storage unit that stores the selected relay paths, and a packet processing unit that replicates packets, each of which is destined for each of the wireless field devices, by the number of the stored relay paths, the packet processing unit storing information indicating a different relay path in each of the replicated packets.
