Abstract
OpenOverlayRouter (OOR) is an open source software router to deploy programmable overlay networks. OOR leverages the Locator/ID Separation Protocol (LISP) to map overlay identifiers to underlay locators, and to dynamically tunnel overlay traffic through the underlay network. LISP overlay state exchange is complemented with NETCONF remote configuration and VXLANGPE encapsulation. OOR aims to offer a flexible, portable, and extensible overlay solution via a user-space implementation available for multiple platforms (Linux, Android, and OpenWrt). In this article, we describe the OOR software architecture and how it overcomes the challenges associated with a user-space LISP implementation. Furthermore, we present an experimental evaluation of OOR performance in relevant scenarios.
