The objective of the paper is to develop the tensor model of buffer storage allocation for the input-output ports of digital network switch. To this end the method of segregated lists applied where each external physical port of the switch comprises internal transit buffers for all other external ports. Through experiments performed, we introduce the notion of zero port for the switch that connects external ports with the switch itself as the object of addressing object. The buffering matrix and the quaternion of an arbitrary couple of buffers is provided for the switch ports. The reduced port buffering matrix is obtained for the even size case of the one-direction interacting input and output buffers. The reduced matrix decomposes in symmetric and anti-symmetric buffering matrix parties. The symmetric buffering matrix is mapped onto the real metric buffering tensor. The anti-symmetric buffering matrix is mapped on two tensors: the real curvature tensor of buffering and complex rotor tensor of buffering. We conclude that it is feasible to use dynamic storage allocation in network switches based on the buffering tensor model. [ABSTRACT FROM AUTHOR]

This paper develops the principles of adaptive interaction of open systems that minimize the administrative traffic and provide the integration of diverse traffic in convergent telecommunication networks. To this end, we employ the method of comparative analysis of benefits and open problems applied to the known concepts of NGN networks. We delineate three future generations of NGN networks with specific development stages and implementation of key technology solutions and ideas. We also determine that the potential packet-based technological platform of NGN networks corresponds to the second future generation networks. The expected advantage of this network generation is high quality of service standards. However, some issues remain unsettled, notably the excessive redundancy of administrative traffic running over the network equipments and channels. We introduce novel approaches for adaptive interaction of open systems that considerably reduces the network loading with administrative traffic and provides the flexible mechanism for the integration of various types of services. Based on the proposed multipurpose network meta-protocol, we conclude that methods of fast packet switching of channels in the future third generation networks should be combined.
