Abstract
Blockchain technology, as a decentralized technology, has been applied across various industries due to its immutability and information security features. With the increasing adoption of blockchain technology, network scale and transaction volumes have increased rapidly. The growing data transmission demands have exposed network performance issues in blockchain systems, creating a bottleneck for further improvements. While Named Data Networking (NDN) offers strong support for blockchain networks, some existing designs lack efficient synchronization methods, resulting in redundancies and limiting the full potential of NDN in blockchain networks. To address this issue, this paper proposes a directed Interest forwarding-based synchronization mechanism for NDN-based blockchain networks. In this mechanism, we design a Block Synchronous Forward Table (BSFT) to record the synchronization status of upstream and downstream nodes. Through the structure of this table, nodes can obtain information about other nodes in the network via six specifically designed NDN Interests. During synchronization, nodes dynamically select the appropriate peers to send data request Interest based on the actual network state and synchronization status, thereby reducing the large number of redundant Interest packets and corresponding response Data packets caused by Interest broadcasts. Experimental results demonstrate that our proposed synchronization mechanism can effectively reduce network traffic, lowering traffic by about 30% or more compared to traditional IP-based blockchain and other NDN-based blockchain solutions. This also accelerates the synchronization of Data packets across the entire network, thereby enhancing the overall performance of blockchain networks.
期刊介绍:
Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms.
Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
