KONOE, a toolkit for an object-oriented online environment, with gate package

KONOE is a toolkit for building a data acquisition, DAQ, system which is used under a network-distributed environment with an object-oriented technology. Several major functions required for a DAQ software, are collecting, recording and monitoring experiment data, and controlling a whole system. Their functions are realized more efficiently and easily by using KONOE. KONOE, so far, has been a toolkit to build a DAQ system under only a local area network, not a global network. The reason why it is not for a global network is the firewall at a connection point to the Internet because of a security reason. Therefore, standard packets to be transferred by user processes are blocked at that point. KONOE packets will also be blocked by the firewall. To solve the problem, the port-forwarding package has been developed. The package works like a gate which opens ports at the firewall. The KONOE packets can pass through the firewall with using this package easily and it is enable to use the DAQ system by KONOE under the global network.
