    Requirements for broadband mobile communications suggest the importance of Metropolitan Area Network (MAN) in Beyond 3G integration. Beyond 3G system accommodates radio systems including 3G, 4G and wireless LANs, and operates all IP network. Ethernet technology has become a suitable solution to cover all access points of various radio systems because of its simplicity and flexibility. A MAN by Ethernet, however, still has issues on scalability. The spanning tree protocol requires so much time to rebuild the tree in a change of topology, especially in a large MAN, and eventually causes much packet loss intolerable to real time applications such as voice and video during the reconfiguration. We propose a scalable spanning tree protocol (SSTP) to realize fast rebuilding of a spanning tree by applying a concept of regions and configure its parameters automatically. Our evaluation shows that SSTP is a solution for future mobile communication networks consisting of thousands of bridges.
