An undirected chordal ring network is an undirected regular graph of degree 3. In [8, 10, 11], Hwang, Chen, and Wright proposed the directed version of the undirected chordal ring network and derived the diameter of a directed chordal ring network. Furthermore, in [3], Chen et al. proposed the mixed chordal ring network. While the diameter of an undirected chordal ring network has been well studied [1], the diameter of a directed chordal ring network and the diameter of a mixed chordal ring network are not known. In this thesis, we shall study the isomorphism property of chordal ring networks and we shall find out the diameter of some directed chordal ring networks and the diameter of some mixed chordal ring networks.
