Scene graph is a infrastructure of the virtual reality system to organize the virtual scene with abstraction, it can provide facility for the rendering engine and should be integrated effectively on demand into a real-time system, where a large quantities of scene objects and resources can be manipulated and managed with high flexibility and reliability. We present a new scheme of multiple scene graphs to accommodate the features of rendering engine and distributed systems. Based upon that, some other functions, e.g. block query, interactive editing, permission management, instance response, ＂redo＂ and ＂undo＂, are implemented to satisfy various requirements. At the same time, our design has compatibility to popular C/S architecture with good concurrent performance. Above all, it is convenient to be used for further development. The results of experiments including responding time demonstrate its good performance.

Network coding is able to address output conflicts when fanout splitting is allowed for multicast switching. Hence, it successfully achieves a larger rate region than non-coding approaches in crossbar switches. Howeve...

A network coding(NC) algorithm based on hardware logic is presented. At first, a synchronous mechanism to solve the challenge of transmission-rate mismatch in the real network is proposed. Then a novel method to accelerate the dot product process over Galois field(GF) is designed. The whole work aims at achieving the wire speed of the hardware logic. Both encoding and decoding operations can be completed in several hundred nanoseconds. The test results show that the NC multicast communication using this algorithm can achieve the limit flow of the max-flow min-cut theorem, and the throughput is improved by using NC.

Because of the petrifaction of the existing network, it is difficult to achieve the controllab.lity, adaptability and expansibility in current structure. Simultaneously, in order to have better campus network services in teaching, researching and studying, a new structure based on reconfigurable architecture for campus network was designed based on service set handling capacity of various kinds of business in reconfigurable network as the central idea. After the evolution from tradition to flat structure, a more condensed structure was proposed by adopting virtualization technology on switches and routers. It has the advantages of high performance, high reliability, manageability and augmentability.
