The Oregon Route-Views project

该项目以通常隐藏在自治系统（as）内部的路由表视图的形式提供数据，有助于对评估路由协议感兴趣的研究人员的工作。俄勒冈路由视图项目（构思于1995年，作为互联网运营商的工具），可从任何连接互联网的主机访问，通过边界网关协议（BGP）从提供路由表（称为“对等”）的as的角度提供互联网路由表的实时视图。route - views使运营商能够访问这些数据，从而能够看到他们的路由状态，以便在路由策略或路由公告更改方面做出明智的决策。这些变化的效果可以立即看到；因此，路由问题可以快速诊断。路由信息库（rib），或路由表和BGP更新包，以支持细粒度监控和研究工作，保存在Route-Views Archive中，提供独特的Internet拓扑视图。计划的工作包括研究影响其产品质量和可用性的挑战：服务器远离数据源，使得BGP会话容易受到中断的影响，从而影响数据路径并导致数据丢失。一组分布式的集合服务器可以解决这个问题。商用路由器不是为数据收集任务而设计的；思科系统7206路由器一直是主要服务器。一种名为Zebra的软件解决方案可以用来克服局限性；但目前存在代码库扩展问题。将添加一些新的感兴趣的数据点。由于数据集非常大，因此需要一种灵活的机制来提取子集，例如基于一段时间或一个特定的前缀。这些操作需要软件包工具和api（应用程序编程接口）。数据收集和存档不是原始设计的一部分。需要努力提高收集的速度、准确性和可靠性，并需要额外的硬件来存档大量数据集。任务包括：定期备份、从磁带中恢复、监控和记录网络事件、管理配置更改、添加和删除对等体、用户支持、软件升级以及向用户分发Route-Views操作信息。更广泛的影响：该项目提供的服务数据将继续成为增长统计、全球连接映射、全球路由系统动态和脆弱性研究以及许多其他全国性研究工作的基础。数据收集站点的扩展和额外的档案应该会改善研究人员和操作人员的平台。

This project, providing data in the form of views of routing tables ordinarily hidden inside of autonomous systems (ASes), contributes to the work of researchers interested in evaluating routing protocols. The Oregon Route-Views project (conceived in 1995 as a tool for Internet operator), accessible from any Internet connected hosts, provides a real-time view of the Internet routing table from the perspective of the ASes that provide their routing tables (referred to as "peering") via Border Gateway Protocol (BGP).Route-Views has afforded operators access to this data, and thus the ability to see the state of their routes in order to make educated decisions about routing policy or route announcement changes. The effect of those changes can be seen immediately; hence routing problems may be quickly diagnosed. Routing Information Base (RIBs), or routing tables and BGP update packets to support fine grained monitoring and research efforts is kept in the Route-Views Archive providing a unique view of Internet topology.Planned work includes studying the challenges that affect the quality and usefulness of its products: Servers are distant from the data sources, leaving BGP sessions vulnerable to outages that affect the data path and result in loss of data. A distributed set of collection servers addresses the problem. Commercial routers are not designed for data collection tasks; the Cisco Systems 7206 router has been the primary server. A software solution, called Zebra, might be used to overcome limitations; but has current code base scaling issues. Some new data point of interest will be added. Since the data sets are quite large, a flexible mechanism is needed to extract subsets, based upon, for example, a period of time or a particular prefix. Package tools and APIs (Application Programming Interface) are required for these operations. Data collection and archiving were not part of the original design. Efforts are needed to improve the speed, accuracy, and reliability of collection, and additional hardware to archive the massive data sets.Tasks include: regular backups, restoring from tape, monitoring and logging network events, managing configuration changes, adding and deleting peers, user support, software upgrades, and dissemination of Route-Views operational information to users. Broader impact: The service data that this project provides will continue to be the basis for growth statistics, global connectivity mapping, research of dynamics and vulnerability of the global routing system, and many other research efforts nationwide. The expansion of data collection sites and additional archives should improve the platform for researchers and operators.
