ABSTRACT:
A communication system is provided in which normal communications can be ensured even upon a loss of synchronization on a part of transmission paths configuring a network.The system is to perform data communications within a network configured by a plurality of devices. A synchronization detecting section detects a loss of synchronization for data transmission between devices connected to each other via the network. Upon detection by the synchronization detecting section of the loss of synchronization, a control information retaining section and a switching section included in the first device cause a connection with the second device to be cut off, and then again cause a connection with the device. Upon connection caused by the switching section between the devices, a connection processing section16performs a connecting process for enabling data communications between these devices.
