By starting with the basic theory of metropolis ring spatial development and drawing the experience of domestic and foreign metropolis ring, the paper makes a discussion on efficiency of metropolis ring pattern, development phases and spatial structure. It points out the three main phases of metropolis ring development—rudiment, growth and autumn. From the spatial structure, the paper stresses that metropolis ring has the features of "ring and layer", the size of the "ring and layer" has the direct ratio with city size, convenient degree of external transportation and city radiant intensity. It owns the idea that adjustment and control of metropolis ring spatial development should reflect the following concepts, including globalization, regional integrated harmony, views of scientific development, harmonious society, consultative city planning, people-oriented principle, guided city planning and responded city planning.

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.

The method to configure RED parameters based on network properties is also presented. Simulations show that the modified Random Early Detection algorithm really performs better than the original Random Early Detection algorithm and can work for a much wider range of traffic. Finally, whether the assured service mechanisms i. e. an edge router tags every arriving packet of a TCP flow based service profile and core router drops packets differently at congestion using active queue management scheme is possible to provide a throughput consistent with target rate, is investigated under different network scenarios. Different factors including target rate tagged algorithm, RIO algorithm and TCP congestion control mechanism how to affect the throughput of an assured service TCP flow are examined. Based on a fluid model. we then derive a model of an assured service TCP flow, which is the function of round trip delay, packet loss rate and token bucket parameters. Based on this model, we observe that in some cases it is possible to regulate the token bucket parameters to gain a consistent throughput with the target rate, while in other cases there exist ranges of values of the achieved rate for which the token parameters have no influence. With the latter, some modified TCP congestion control mechanisms to assure TCP throughput are proposed.

Given a ring and a set of communication requests. Each request is represented by a pair of nodes, and associated with a profit. To satisfy a request in the undirected ring, we need to determine a path between the two nodes of the request in the ring. To satisfy a request in the directed ring, we need to determine a directed path from the source to the destination of the request in the directed ring. The goal of the call admission control problem is to determine and satisfy a maximum profit subset of the requests such that for every edge of the ring, the number of satisfied requests that are routed through the edge does not exceed the capacity of the edge.
