New groups of writers and new writing styles are constantly springing up and existing theoretical criticism has been attacked and torn apart, with the result that it has often lost its voice. With the rapid growth of online literature, the influence of non-mainstream literature in the domain of literary reading and consumption is increasing. Consequently, the above-mentioned problem is evolving into a new contradiction, i.e. a lack of mutual understanding and tolerance with regard to reading. In the past decade, an enormous number of novels have come out online, falling into over twenty categories. This paper takes into account both chronology and type of writing in selecting for review ten outstanding works of different genres from the last decade, stressing the aesthetic qualities and distinctive styles that differentiate them from their print counterparts.展开更多

Although much work has been carried out on the integration of NDN and SDN, the forwarding mechanism to solve the inherent problems caused by the flooding scheme and discard of interest packets in traditional NDN is not well considered. To fill this gap, by taking advantage of SDN, we design a novel forwarding mechanism in NDN architecture with distributed controllers, where routing decisions are made globally. Then we show how the forwarding mechanism is operated for interest and data packets. In addition, we propose a novel routing algorithm considering quality of service（QoS） applied in the proposed forwarding mechanism and carried out in controllers. We take both resource consumption and network load balancing into consideration and introduce a genetic algorithm（GA） to solve the QoS constrained routing problem using global network information. Simulation results are presented to demonstrate the performance of the proposed routing scheme.展开更多
