Claim Text:
1. A transmission apparatus comprising: a cross-connect unit configured to multicast or broadcast concatenation information; an assigning unit configured to assign a group number to a group of concatenation information of leading data and concatenation information of dependent data which are multicast or broadcast by the cross-connect unit; a retrieval unit configured to retrieve the concatenation information of the leading data corresponding to the dependent data, the leading data and the dependent data having the same group number assigned by the assigning unit; a regeneration unit configured to regenerate concatenation information of the dependent data in accordance with the concatenation information of the leading data retrieved by the retrieval unit; a storage unit configured to store switch information of the leading data, the switch information representing a switch which switches output destinations of the leading data and the dependent data; an information retrieval unit configured to refer to the storage unit in accordance with leading data information included in the concatenation information of the dependent data regenerated by the regeneration unit so as to retrieve switch information of the dependent data corresponding to the concatenation information regenerated by the regeneration unit; and a switching unit configured to switch the output destination of the dependent data in accordance with the switch information retrieved by the information retrieval unit, wherein at least one of the leading data and the dependent data are included in an optical signal, wherein the retrieved switch information of the dependent data is not same as the concatenation information regenerated by the regeneration unit.
