STI-XTend augments the X-Bone automated Internet overlay deployment and management tool to provide a secure environment for local and distributed network experiments, to support advanced research and classroom use. The X-Bone applies a Virtual Internet architecture to support secure, concurrent overlay networks (VPNs) using existing Unix operating systems, standard Internet protocols (IPsec, SSL, dynamic routing), and applications. It currently lacks some advanced facilities requested by a number of network researchers and faculty. STI-Xtend augments the X-Bone to support revisitation, dynamic topology control, ports it to additional platforms, and augments its API for integration with networked applications. The tool will be further packaged with additional support materials (examples, scripted demonstrations, and instructions) to enhance its use by the research and educational community. The extensions are:Support large-scale network emulation: STI-XTend allows overlays to revisit network components, allowing a small set of devices to emulate a large network using real protocols and applications. Dynamic topology control: STI-XTend allows overlay topologies to be modified by adding or deleting nodes or links, and to specify subset of responding nodes used (vs. arbitrary selection). This provides precise control of the participants and topology, allowing repeatable deployments.Support additional platforms: The X-Bone supports Unix hosts and host-based routers; STIXTend provides ports for other platforms (MacOS, Solaris) and adds IPv6, multicast, and a single-board system for modest installations and control of closed platforms.Augment user interfaces, API, and components: STI-XTend augments the X-Bone's GUI and updates its modular components and capabilities, e.g., dynamic routing (currently using defunct GateD and MRTd). The X-Bone is based on the abstract Virtual Internet (VI) architecture, which describes concurrent parallel and hierarchical overlays. The VI model inspired two-layer encapsulation to uniquely integrate IPsec with dynamic routing, and is being used to unify web search, DNS lookup, IP forwarding, and ARP (media-layer address resolution) as instances of a single, generic service. STI-XTend augments the VI architecture to include revisitation and dynamic topology control (especially difficult with IPsec, IPv6, and dynamic routing), as well as ensuring the correctness of the X-Bone API.Over the past 3 1/2 years, there have been 4 public code releases and 18 public demonstrations of the X-Bone software. It is part of the FreeBSD ports collection and available as a Linux RPM.

STI-XTend增强了X-Bone自动化互联网覆盖部署和管理工具，为本地和分布式网络实验提供安全的环境，以支持高级研究和课堂使用。X-Bone采用虚拟互联网架构，使用现有的Unix操作系统、标准互联网协议（SSL、动态路由）和应用程序来支持安全的并发覆盖网络（VPN）。它目前缺乏一些网络研究人员和教师所要求的先进设施。STI-Xtend增强了X-Bone以支持修订、动态拓扑控制，将其移植到其他平台，并增强了其API以与网络应用程序集成。该工具将进一步与其他支持材料（示例、脚本演示和说明）打包，以加强研究和教育界对其的使用。支持大规模网络仿真：STI-XTend允许覆盖层重新访问网络组件，允许一小组设备使用真实的协议和应用程序来仿真大型网络。动态拓扑控制：STI-XTend允许通过添加或删除节点或链路来修改覆盖拓扑，并指定所使用的响应节点的子集（与任意选择相比）。支持其他平台：X-Bone支持Unix主机和基于主机的路由器; STIXTend为其他平台提供端口（MacOS，Solaris），并增加了IPv6、多播和单板系统，用于适度安装和控制封闭平台。STI-XTend增强了X-Bone的GUI并更新了其模块化组件和功能，例如，动态路由（目前使用已失效的GateD和MRTd）。X-Bone基于抽象的虚拟互联网（VI）架构，该架构描述了并发并行和分层覆盖。VI模型启发了两层封装，以独特的方式将DNS与动态路由集成在一起，并被用于将Web搜索、DNS查找、IP转发和阿普（媒体层地址解析）统一为单个通用服务的实例。STI-XTend增强了VI体系结构，包括重新访问和动态拓扑控制（特别是在IPv6和动态路由的情况下），以及确保X-Bone API的正确性。在过去的3年半时间里，X-Bone软件已经发布了4个公开代码版本和18个公开演示。它是FreeBSD ports集合的一部分，并作为Linux RPM提供。
