面向命名数据网络的数据查询区分服务机制
Differentiated Service Mechanism for Data Query on Named Data Networking
摘要
Abstract
In Named Data Networking(NDN), there is a great challenge for discovering and collecting the needful infor-mation from massive and distributed data, which needs to orchestrate complex routing and distributed processing compo-nents and adapt to network capabilities. Therefore, the paper proposes a differentiated service mechanism for NDN-based data query by following the design principle of the differentiated service in the current network. Inspired by the labeling idea of the MPLS protocol, the personalized and complex data query requirements are converted into multiple labels and their combination, which includes the interest forwarding labels and data returning labels. In the forwarding and response phase, the different processing actions of interest and response are determined by the individual labels and their combination. The NDN-based differentiated service system structure and the implementation process are proposed for personalized data query and accommodating network capabilities. Finally, the security of the labels and application scenarios of the differen-tiated service mechanism are discussed.关键词
