摘要
5G as an evaluative mobile communication network is expected to respond to the traffic volume explosion and the diverse demands for communication. For the deployment of 5G, there have been many researches of heterogeneous network, especially they employ for named data networking (NDN). As a future network architecture, NDN focuses on the content, where forwarding information base (FIB) performs name-based forwarding to achieve the communications. In this paper, a novel FIB named B-MaFIB is proposed to enhance the performance of NDN router that well supports heterogeneous network toward 5G, which is designed based on an improved index called a bitmap-mapping bloom filter (B-MBF). Owing to the B-MBF, the B-MaFIB can dynamically allocate memory to effectively reduce the memory consumption. The experimental results indicate that for 2 million names based on 5G, B-MaFIB: 1) only consumes memory with 112.079 MB, reaching 50% memory reduction and 2) achieves a throughput of 1.099 million searches per second, obtaining at least six times speedup over the other schemes, which provides a potential in the deployment of NDN router.
