Latest Patents

Tan’s listed patents address network control and topology management.

“Method and Apparatus for Controlling Multiple Registration Protocol (MRP) Scope Using MRP Policies” describes a device that manages MRP advertisements between a core domain and a local domain. The device applies stored policies to determine whether advertisements should be forwarded. For example, advertisements associated with local services can be kept within the local domain, while advertisements for inter-domain services can be forwarded between the local and core domains.

“Extensions to the Spanning Tree Protocol” describes a way to provide redundancy and prevent loops in a service domain operating over a provider core network. The approach defines a virtual core port at participating provider-edge devices and associates it with a virtual core bridge. The system is configured so that the virtual core bridge becomes and remains the root bridge.
