Claim Text:
1. A data transmission system comprising: a transparent main optical packet ring comprising a plurality of separate packet transmission channels; and a plurality of transparent secondary optical packet rings interconnected through said main optical packet ring; each of said secondary optical packet rings comprising a plurality of nodes, wherein each of said packet transmission channels of the main optical packet ring is connected to a different node of each secondary optical packet ring, respectively; and wherein each node comprises: a first transmitter unit and a first receiver unit respectively connected to a packet transmission channel of the main optical packet ring, a second transmitter unit and a second receiver unit respectively connected to one of the secondary optical packet rings, a data interface connectable to at least one data processing unit, and a switching unit directly connected to the first transmitter unit, the first receiver unit, the second transmitter unit, the second receiver unit and the data interface, and configured to selectively establish connection paths between the first receiver unit or the second receiver unit and the first transmitter unit or the second transmitter unit, or between one of the first receiver unit, the second receiver unit, the first transmitter unit, or the second transmitter unit and the data interface; wherein each node comprises: a first optical packet control interface connected to a first optical packet blocker coupled with the main optical packet ring, wherein the node is configured to forward first blocking information through the first optical packet control interface to the first optical packet blocker, the first blocking information indicating whether optical packets traveling on the main optical packet ring are to be blocked or passed through by the first optical packet blocker, and/or a second optical packet control interface connected to a second optical packet blocker coupled with the secondary optical packet ring of the node, wherein the node is configured to forward second blocking information through the second optical packet control interface to the second optical packet blocker, the second blocking information indicating whether optical packets traveling on the secondary optical packet ring are to be blocked or passed through by the second optical packet blocker.
