An Empirical Model of Packet Processing Delay of the Open vSwitch

Network virtualization offers flexibility by decoupling virtual network from the underlying physical network. Software-Defined Network (SDN) could utilize the virtual network. For example, in Software-Defined Networks, the entire network can be run on commodity hardware and operating systems that use virtual elements. However, this could present new challenges of data plane performance. In this paper, we present an empirical model of the packet processing delay of a widely used OpenFlow virtual switch, the Open vSwitch. In the empirical model, we analyze the effect of varying Random Access Memory (RAM) and network parameters on the performance of the Open vSwitch. Our empirical model captures the non-network processing delays, which could be used in enhancing the network modeling and simulation

Impact of Trade on Labour Productivity and Wage Inequality in India

Abstract: The paper empirically estimates the impact of trade on labour productivity and wage inequality between skilled (white collar) and unskilled (blue collar) labour in Indian manufacturing. Analysis is undertaken using dynamic panel data estimations (GMM) for 58 manufacturing industries for the period 1998-99 to 2004-05. The results show that export intensity of industries has positively impacted productivity of unskilled labour while import competition has led to higher productivity of both skilled and unskilled labour. However, trade has led to increase in wage inequalities between skilled and unskilled labour implying that it has increased the wages of skilled labour more than the unskilled labour.Trade and Wage Inequality; labour productivity; wage inequality between skilled and unskilled labour; Wage Inequality; Indian manufacturing and labour productivity; Indian manufacturing and wage inequality; Labour productivity of unskilled labour
