  • Communication network system and method for synchronously controlling path connection
    Patent number: 7035264
    Abstract: An ATM network for synchronously perform a path connection control at a plurality of nodes, wherein path control data are preliminarily supplied to the nodes from a network management system before a designated operation time. Each node generates a current time synchronously with a network synchronous clock, selects path control data by comparing the designated operation time of the control data with the current time, and autonomously executes a path connection control in accordance with the selected path control data.
