论文摘要
作为潜在的未来互联网体系结构，命名数据网络（NDN）为移动临时网络提供了卓越的以信息为中心的架构支持。最终用户设备（例如，IoT设备和智能手机）使用NDN作为基础协议，制定了多跳（网格）网络，其中某些设备在为他人转发数据包和/或作为访问Internet的网关中发挥了作用。然而，临时网络中的自主（自私）节点有两种用于转发数据包的抑制作用：能量支出和可能的数据延迟。本文使用区块链作为支付平台来支持自动节点之间的货币转移，从而激励数据包转发。在PPTP中，路由器宣传其针对数据包转发的预期价格，消费者估计成本，并选择适当的内容下载途径。 PPTP仍然是一个正在进行的项目，因此本文将介绍设计原理和计划的功能，并展示PPTP与其他基于区块链的网络解决方案的关系。
Serving as a potential future Internet architecture, Named Data Network (NDN) offers superior information-centric architectural support for mobile ad-hoc networking. Using NDN as an underlying protocol, end-user devices (e.g. IoT device and smart phone) formulate a multi-hop (mesh) network, in which certain devices play a role of forwarding packets for others and/or act as gateways to access the Internet. Nevertheless, an autonomous (selfish) node in an ad-hoc network has two disincentives for forwarding packets for others: energy expenditure and possible delays for its own data. This paper introduces Price-based Path-specified Transport Protocol (PPT) for NDN, using blockchain as a payment platform to support money transfers between autonomous nodes thus to incentivise packet forwarding. In PPTP, routers advertise their expected prices for packet forwarding and consumers estimate the costs and select the appropriate paths for content downloading. PPTP is still an on-going project therefore this paper will present the design principle and planed functions, and show how PPTP are related to other existing blockchain-based networking solutions.
