Abstract
Systems and methods for providing graceful insertion of a station or tree into a ring type network. According to one aspect of the invention, graceful insertion is achieved after coupling a tree to a tree link of a master port by switching the tree into a local ring, holding the local ring, and awaiting a token on the network ring. After a token is received on the network ring, the tree is switched from the local ring to the network ring. Monitoring ring status in hardware provides the responsiveness necessary which software graceful insertion typically cannot provide.
