As a promising candidate architecture for future access network, Fiber-Wireless (FiWi) access network is also suffering from the bottleneck of resource allocation and optimization due to the complexity and diversity of traffic demands. Although the emerging network virtualization technology has provided a feasible way for FiWi to break the bottleneck,(More)
Keywords clustering, as the basic method of domain knowledge analysis, has some problems such as difficult to understand the clustered tree diagram, scarce of further analysis methods, etc. The paper proposed a new approach to analyze domain knowledge based on keywords clustering. The proposed weighted knowledge model (WKN) is composed of two types of nodes(More)
Considering the importance of user-innovation knowledge to product and service innovation, this paper proposed knowledge discovering and analyzing methods on user-innovation communities based on weighted knowledge network (WKN). First, web mining methods were used for getting forum posts in virtual user-innovation communities, then the acquired keywords and(More)
With the rapid development of converged network technology, the network shows an obvious trend to be heterogeneous. In order to solve this problem, this paper proposes a multi-controller collaborative interconnection architecture for multilayer heterogeneous SDON (Software Defined Optical Network). And to enable this architecture, OpenFlow protocol is(More)
