k-regular and k-(edge)-connected protection structures in optical transport networks

We construct k-regular and k-(edge)-connected structures for providing protection against multiple failures in optical transport networks. It improves the spare resources efficiency without increasing the complexity of design and implementation of protection mechanisms.
