ABSTRACT:
A method for establishing a hierarchical network with Backbone Provider Bridges includes: dividing the network into a plurality of layers, and partitioning each layer into at least one domain; each domain assigning a service tag for itself; a local domain sending a mapping request including a user type ID to a further domain in the same layer; the further domain in the same layer returning a service tag corresponding to the user type ID to the local domain; the local domain establishing and saving a mapping relationship; and edge devices of each domain learning MAC addresses. Further, a system and device having the same are also provided in the disclosure.
