Due to the variable length and uniqueness of names in NDN, traditional IP address-based routing and forwarding architecture is no longer suitable for NDN networks. It is still a challenge to design a high-performance forwarding engine to solve the problem of variable name length and uniqueness in NDN. In this article, Residue Number System (RNS) is applied to the routing and forwarding of NDN for the first time, and a new forwarding engine framework based on the RNS is designed. The simulation results show that this method has a significant performance increase in memory space and system latency. At the core-level node, the RNS-based process requires only about 5 percent of Bloom Filter (BF) in terms of memory space and has a 9.8 percent decrease in system latency compared to applying BF (P=1E-08). This method not only achieves less memory usage and reduces the system latency but also fundamentally solves the false positives and has good scalability due to the superiority of the algorithm itself. The proposed work is admirably suited for realizing large-scale NDNs by hardware implementation of NDN routers.INDEX TERMS Named data networking (NDN), packet forwarding engine (PFE), residue number system (RNS), membership querying.
There exists the phenomenon that college students display poor performance in English learning,especially in the
aspect of clause learning.In order to address such problem,this paper would try to analyse the application of Constructivism to
attributive clause in college English teaching,offering theory analysis and teaching examples.The teaching samples would include
attributive clause learning and attributive clause writing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
