Claim One:
1. A data center network architecture, comprising: at least one optical ring network of junction nodes, the optical ring network of junction nodes including at least a first junction node and a second junction node; and one or more optical ring networks of user nodes, wherein the first junction node is communicably coupled to at least a first user node on the one or more optical ring networks of user nodes, wherein the second junction node is communicably coupled to at least a second user node on the one or more optical ring networks of user nodes, thereby interconnecting the first user node and the second user node on the one or more optical ring networks of user nodes via the optical ring network of junction nodes, wherein the first junction node and the second junction node each include a plurality of inputs, a plurality of outputs, and a plurality of connection paths disposed between the plurality of inputs to the plurality of outputs, wherein the plurality of inputs of each first and second junction node are in a first predetermined sequence, wherein the plurality of outputs of each first and second junction node are in the first predetermined sequence, wherein the plurality of inputs and the plurality of outputs of each first and second junction node have predetermined positions in the first predetermined sequence, and wherein, for each first and second junction node, at least some of the plurality of connection paths are each operative to communicably couple a specific input to a specific output, the predetermined positions of the specific input and the specific output in the first predetermined sequence differing by at least one position in the first predetermined sequence.
