Transmission apparatus and method

摘要

A transmission apparatus includes an acquisition device that acquires a switch request for plural types of transmission sections overlapping with one another at least at apart of the sections, a selection device that selects one of the switch requests for plural types of transmission sections according to priority level information about a priority level corresponding to each of the plural types of transmission sections, and a switch device that switches the transmission paths depending on the selected switch request.

1. A transmission apparatus comprising:
an acquisition device that acquires a plurality of switch requests for a transmission path of a signal in plural different types of hierarchized transmission sections, at least a part of the hierarchized transmission sections overlapping one another; a selection device that selects a switch request for the transmission path of the signal in any one of the hierarchized transmission sections of the plurality of switch requests based on priority level information including a priority level corresponding to each of the plural different types of hierarchized transmission sections, the priority level being set depending on whether or not another transmission apparatus which transmits each of the switch requests is adjacent to the transmission apparatus which acquires the switch requests; a switch device that switches the transmission paths of a hierarchy depending on the selected switch request; and a transmission device that transmits switch execution information indicating that the transmission paths are switched depending on the selected switch request to another transmission apparatus accommodated in a transmission section which accommodates the transmission apparatus as an intermediate node.
