The explosion of the Internet is still continuing due to the expansion of the number of users and multimedia services. To replace the conventional router network, a new paradigm of some multi-layer switching techniques are proposed in the standardization sectors and forums. We estimate the best solution for a very large scale Internet backbone, i.e. a nationwide scale. After estimating the size of the Internet in the future, we study the high speed internetworking solutions. We especially compare the multiprotocol label switching (MPLS) and CL (connectionless)-network from the view point of scalability and the size of the buffers of each node.
