As a general rule, it aims at the MPLS networks with the protection paths created in advance of fault occurrence without resources reserved, and it reroutes the protected traffic in the event of link or router failures while trying to maintain quality of service (QoS) requirements. Based on the proposed protocol for processing faults, an analytical model and an evaluating model are created, and the benefits and penalties of different mechanisms with different protection policies are evaluated. In particular, an improvement on the proposed protocol is presented to overcome the drawbacks of n:m protection policy in which m > 1 and n > 1.展开更多

To get rid of what is out-of-date and take in fresh perspectives, we need to eliminate the current methodological bottleneck and take full advantage of multivariate research methods to explore the complex interactions among variables and develop a basic analytical framework. First, strategic behavior should be divided into four stages, i.e., strategic assessment, strategic decision-making, strategic mobilization and strategic implementation, then the factors affecting each stage should be clarified and their interactions grasped. A preliminary framework for understanding state strategic behavior will help to promote the in-depth development of this field of research.展开更多

To achieve a sustained development of economy, we must require the taxes which are closely related to economy meet the requirements of its own development. That is tax receipts raised by government meeting functional needs as much as possible, while reducing the facts that will damage the future needs and development of economy. Therefore, we need to analyze various factors that affect revenue. If we make a very good understanding on how structure impacting on tax revenues, that will help us to use policy tools tax making impacts on revenue and optimize the structure of the tax. For this theme, many domestic scholars have done correlation research, and their research paper provides a good reference, but we believe their research can be further refined. Through theoretical analysis, we can select appropriate indicators letting tax revenue to be explained variable. Each possible influencing factor of tax revenues establish measurement model for explaining variable using stepwise regression models, and make a rigorous statistical test on the model. On the base of fully proving the effectiveness of the model, we can make relevant economic analysis.展开更多
