<p>A trunk and branch logical ring network includes a plurality of nodes that are coupled to a ring backbone by a plurality of branching units. The connections to the ring backbone are such that physically adjacent nodes are not adjacent to one another logically in the network. By providing this alternating branching arrangement the maximum length of any unregenerated span along the ring is significantly reduced. This reduces repeater spacing in the network.</p> |
