Content delivery, security, high-availability failover and log analytics come together in one system, with a single control plane managing edge nodes, origin relays and origins. The control plane and the nodes run on your own servers, and you keep the configuration, the logs and the data. 查看授权版本See editions 了解系统架构See the architecture ✓数据保留在自有网络Data stays in your network ✓支持 HTTP/2 与 WebSocket 反向代理HTTP/2 & WebSocket reverse proxy ✓ACME 证书自动签发与续期ACME certificates issued and renewed automatically funcdn · 主控control plane 私有化self-hosted 基础功能Core 域名管理Domains 源站池Origin pools 缓存策略Cache rules 安全策略Security policy SSL 证书SSL certs 基础设施Infra 边缘节点Edge nodes 回源中继Origin relays 高可用规则HA rules 请求链路Request route 用户User → 边缘节点Edge → 中继·可选Relay·opt → 源站Origin 边缘处理At the edge 缓存Cache 安全防护Security TLS HTTP/2 WebSocket 配置通过 gRPC 实时下发至节点；与主控断连时，节点继续使用本地缓存配置提供服务 Config streams to nodes over gRPC.

The homepage lists the highlights; the capabilities page covers each one in detail. 站点接入与缓存Delivery & caching 域名接入后，流量由源站池负载均衡，并配主动健康检查；缓存分内存和磁盘两级，一键刷新下发到节点。Once a domain is onboarded, traffic is load-balanced across the origin pool, with active health checks behind it. The cache has two tiers, memory and disk, and a one-click purge is pushed out to the nodes. 安全防护Security WAF、IP 黑白名单、访问限速、CC 防护和 JS Challenge，策略统一下发到边缘，每个站点可以单独组合。WAF, IP allow and deny lists, rate limiting, CC defense and JS Challenge. Policies are pushed to the edge from one place, and each site can combine them differently. 证书与 DNSCertificates & DNS 证书可以手动上传，也可以走 ACME 自动签发和续期。另外支持 CNAME Target，以及多家 DNS 服务商的授权接入。Upload certificates manually, or let ACME issue and renew them automatically. There is also CNAME target support and credentials for multiple DNS providers. 日志分析Log analytics 访问、缓存、回源和高可用日志都有记录，另有探测和审计。做日志分析时，可以选择接入外置 ClickHouse。Logs cover access, cache, origin pull and high availability, with probing and audit alongside them. Log analytics can optionally connect to an external ClickHouse. 节点运维Node operations cdn-agent 采用签名升级，配置实时下发，节点侧用本地缓存做容错。健康心跳、备份恢复和操作审计也一并提供。cdn-agent upgrades are signed, config is pushed live, and nodes fall back to their locally cached copy. Heartbeats, backup and restore, and an operation audit trail are provided as well. 开发者接口Developer interfaces REST API 配 API Token，接口按 OpenAPI 3.0 规范描述。边缘规则、脚本模板和用户 Edge KV 也都支持。A REST API with API tokens, described by an OpenAPI 3.0 spec. Edge rules, script templates and user Edge KV are supported as well. 查看全部产品能力 →See all capabilities → 完整清单同样覆盖节点运维、日志分析和开发者接口The full list also covers node operations, log analytics and developer interfaces 02 · 系统架构Architecture 请求面、主控与数据面相互独立Request, control and data planes stay separate 主控负责编排和配置下发，业务请求由边缘节点自己承载。节点与主控暂时断连时，仍按本地缓存的配置继续服务；运行日志则单独汇入日志分析数据面。The control plane handles orchestration and config push, while edge nodes carry the request traffic themselves. If a node loses its connection to the control plane for a while, it keeps serving from the config it has cached locally. Operational logs take a separate path into the log analytics data plane. ✓主控：基于 REST 与 gRPC 进行编排和配置下发Control plane: orchestration and config push over REST + gRPC ✓请求面：节点断连时仍可基于本地缓存配置继续服务Request plane: nodes keep serving from local cached config when disconnected ✓数据面：日志可选汇入外置 ClickHouse，用于日志分析Data plane: logs can flow into an external ClickHouse for analytics 查看完整架构 →See the full architecture → 请求处理链路Request handling path 架构概览Overview 请求链路Request route 用户User → 边缘节点Edge → 中继·可选Relay·opt → 源站Origin 主控 · 编排与配置下发Control · orchestrate 请求面 · 边缘节点承载业务流量Request · at the edge 数据面 · 日志与日志分析Data · analytics 配置通过 gRPC 实时下发至节点；与主控断连时，节点继续使用本地缓存配置提供服务 Config streams to nodes over gRPC.

The rest, along with the capabilities behind them, are on the use cases page. SCN 01 自建 / 私有化 CDNSelf-hosted CDN 内容分发跑在自己的服务器和带宽上。主控和节点都在自有网络里，配置和日志不用出内网。Content delivery runs on your own servers and bandwidth. The control plane and the nodes both sit inside your network, so configuration and logs never have to leave it. 私有化部署Self-hosted数据留在内网Data in-network SCN 03 多源站容灾Multi-origin resilience 源站池做负载均衡，同时用主动健康检查发现故障，再自动切到可用的源站。也可以部署回源中继，当作备用的回源链路。The origin pool load-balances traffic and uses active health checks to detect failures, then switches automatically to a healthy origin. An origin relay can also be deployed as a backup path to the origin. 源站池Origin pools故障切换Failover SCN 05 页面级高可用Page-level high availability 关键站点可以挂高可用规则。主地址请求失败后，浏览器按顺序探测预设的备用地址，跳到第一个能通的；备用地址全部不可达，才显示离线页面。仅增强版和定制版可用。Critical sites can have HA rules attached. After a request to the primary fails, the browser probes the preset backup addresses in order and redirects to the first reachable one. The offline page appears only if none of the backups are reachable.

The full answers on deployment, licensing, quota, high availability, log analytics and legacy compatibility are on the FAQ page. FunCDN 采用什么部署方式？What deployment model does FunCDN use? 私有化、自建。一套系统包含主控（API 服务与管理面板）、边缘节点、可选的回源中继，以及常驻在每台主机上的 cdn-agent。这些组件都原生运行在您自己的 Linux 服务器上，由主控统一编排。Private and self-hosted. A system is made up of the control plane (the API service and the web panel), edge nodes, an optional origin relay, and a cdn-agent resident on every host. All of them run natively on your own Linux servers, orchestrated by the control plane. 哪些版本支持高可用？能力边界是什么？Which editions support HA, and what's its scope? 页面级高可用只向增强版和定制版开放。全功能版能看到功能入口，但要用起来需要升级。它只对页面导航请求做容灾切换，并不是把站点的全部子资源都透明接管。查看高可用工作原理 →Page-level HA is available in Enhanced and Custom only. The Full edition shows the entry point but needs an upgrade before you can use it. Failover applies to page-navigation requests only; it does not transparently take over all of a site's sub-resources. See how HA works → 域名配额如何计算？How is the domain quota calculated? 按节点数和 Zone 数量算。一个 Zone 就是一个根域名，它底下的子域名都算进同一个 Zone，不额外占配额。实际的配额上限以授权文件为准。By node count and Zone count. One Zone is one root domain, and every subdomain under it belongs to that same Zone without using extra quota. The actual ceiling comes from your license file. 查看全部常见问题 →See all FAQs → 按需要选择授权版本和档位Choose the edition and tier you need 按节点数和授权站点数（以根域名 Zone 计）透明计费。选哪一档看实际部署规模，选哪个版本看您需要哪些高级功能与服务。Transparent pricing, based on licensed node count and licensed sites counted per root-domain Zone.
