课程名称：定位器/ID分离协议（LISP） 讲师：Arash Deljoo 课程概述：随着互联网的持续增长，面临着诸多挑战，其中一个最基本的挑战是确保路由和地址系统在连接设备数量不断增加的情况下仍能高效运作。在早期的网络研究与开发过程中，发现单一的IP地址同时包含身份和位置，这导致了次优的路由扩展性，并且妨碍了多宿主和设备移动性。定位器ID分离协议（LISP）提供了改进的路由扩展性，并促进了多宿主、提供者独立性、移动性和虚拟化的灵活地址分配。LISP通过引入两个独立的IP地址提供了传统互联网架构的替代方案：一个用于标识路由定位器（RLOC），用以在全球互联网中路由流量，另一个用于标识网络会话的端点标识符（EID）。 LISP是一个网络架构和协议，采用两个命名空间而非单一IP地址： - 端点标识符（EID）- 分配给最终主机。 - 路由定位器（RLOC）- 分配给构成全球路由系统的设备（主要是路由器）。 分离EID和RLOC的功能带来了多个优势，包括改善路由系统的扩展性，提高多宿主效率和入口流量工程。LISP的功能需要LISP特定配置的一个或多个相关设备，如LISP出口隧道路由器（ETR）、入口隧道路由器（ITR）、代理ETR（PETR）、代理ITR（PITR）、映射解析器（MR）、映射服务器（MS）以及LISP替代逻辑拓扑（ALT）设备。
The continuous growth of the Internet presents a number of challenges. Among the most fundamental of these challenges is ensuring that the routing and addressing system continues to function efficiently even as the number of connected devices continues to increase. A basic observation during early network research and development work was that the single IP address, which includes both identity and location, leads to suboptimal route scaling and hinders multihoming and device mobility.Locator ID Separation Protocol (LISP) provides improved routing scalability and facilitates flexible address assignment for multi-homing, provider independence, mobility, and virtualization. LISP offers an alternative to traditional Internet architecture by introducing two separate IP addresses: one to indicate routing locators (RLOCs) for routing traffic through the global Internet and a second address for endpoint identifiers (EIDs) used to identify network sessions between devices.Locator ID Separation Protocol (LISP) is a network architecture and protocol that implements the use of two namespaces instead of a single IP address:Endpoint identifiers (EIDs)-assigned to end hosts.Routing locators (RLOCs)-assigned to devices (primarily routers) that make up the global routing system.Splitting EID and RLOC functions yields several advantages including improved routing system scalability, and improved multihoming efficiency and ingress traffic engineering.LISP functionality requires LISP-specific configuration of one or more LISP-related devices, such as the LISP egress tunnel router (ETR), ingress tunnel router (ITR), proxy ETR (PETR), proxy ITR (PITR), map resolver (MR), map server (MS), and LISP alternative logical topology (ALT) device.
