AS 拓扑不完整性问题源于发现 p2p 链路的困难，并因支持对等互连的互联网交换点 (IXP) 的日益普及而加剧。我们描述、实现和验证了一种通过挖掘 IXP 路由服务器使用的 BGP 社区来发现当前不可见的 IXP 对等链路的方法，以实现多边对等 (MLP)，包括表示将公告限制为给定 IXP 的一部分参与者的意图的社区。将路由服务器数据与 BGP 社区值的映射并列使用，我们可以从 13 个大型欧洲 IXP 推断出 206K p2p 链路，比公共 BGP 数据中直接观察到的 p2p 链路多四倍。所提出的技术有三个优点。首先，它利用现有的 BGP 数据源，不需要部署额外的优势点，也不需要获取私有数据。其次，它只需要一些主动查询，从而促进测量的可重复性。最后，它提供了有关在 IXP 上密集建立 MLP 的新数据源。
The AS topology incompleteness problem is derived from difficulties in the discovery of p2p links, and is amplified by the increasing popularity of Internet eXchange Points (IXPs) to support peering interconnection. We describe, implement, and validate a method for discovering currently invisible IXP peering links by mining BGP communities used by IXP route servers to implement multilateral peering (MLP), including communities that signal the intent to restrict announcements to a subset of participants at a given IXP. Using route server data juxtaposed with a mapping of BGP community values, we can infer 206K p2p links from 13 large European IXPs, four times more p2p links than what is directly observable in public BGP data. The advantages of the proposed technique are threefold. First, it utilizes existing BGP data sources and does not require the deployment of additional vantage points nor the acquisition of private data. Second, it requires only a few active queries, facilitating repeatability of the measurements. Finally, it offers a new source of data regarding the dense establishment of MLP at IXPs.
