Balanced Hash Tree (BHT) is a mechanism for service function (SF) chaining, service routing, and traffic steering that enables switches to select SF instances for load balancing without involving the controller. In an experimental evaluation, BHT decreased packet-in message-processing time by 92.5 percent and achieved near-perfect load-balancing performance.

During the global financial crisis in 2008, governments around the world have used a variety of policies to support threatened industries and to stabilize financial systems. In the present study, we empirically compare the patterns of the dynamic change in the financial performance of the semiconductor industry before and after government intervention by using the piecewise linear trajectory model for Japan, South Korea and Taiwan, three major economies for the industry. The empirical results indicate that during the global financial crisis, the performance of the semiconductor industry can benefit from government support, in spite of the fact that the improvement was somewhat delayed after intervention. Moreover, the change pattern of the performance depends on the performance factor and the economy. Based on the results obtained as well as literature support, we summarize the economic and industrial policies that might have demonstrated usefulness for the industry and discuss some implications.

Earnings management is popular in the banking industry. Earnings can be manipulated by discretionary loan loss provisions (DLLP). Analysing the trajectories of banks' DLLP (i.e. their change in DLLP over time) is an effective way to assess the performance in earnings management for the banking industry, but seems not to have been addressed in the earnings management literature. In this study, we analyse the trajectories of DLLP with the yearly data from 2007 through 2012 for four types of banks in China. The results have indicated that state-owned banks, policy banks and city commercial banks seem to manage earnings well. Cautionary notes about bank risks are provided.
