新一代自建 CDN 系统，
全新架构 自主可控
A next-generation self-hosted CDN,
redesigned for full control
FunCDN 是一套可私有化部署的自建 CDN 系统。通过统一主控管理边缘节点、回源中继和源站，将内容分发、安全防护、高可用容灾与日志分析整合在同一平台中。主控和节点均运行在您自己的服务器上，配置、日志与数据由您自主掌控。 FunCDN is a self-hosted CDN system you deploy privately. A single control plane manages edge nodes, origin relays and origins, bringing content delivery, security, high-availability failover and log analytics together on one platform. The control plane and nodes run on your own servers, and configuration, logs and data stay under your control.

01 · 产品能力Capabilities
自建 CDN 系统所需的核心能力，一个主控统一管理Every core capability a self-hosted CDN needs, managed from one control plane
站点接入、缓存与回源、安全防护、证书、日志分析、节点运维和开发者接口，均可在同一主控中统一配置和管理。以下为能力概览，详细内容请查看产品能力页。Site onboarding, caching and origin pull, security, certificates, log analytics, node operations and developer APIs — all configured and managed from one control plane. This is an overview; see the capabilities page for the details.
安全防护Security
支持 WAF、IP 黑白名单、访问限速、CC 防护和 JS Challenge；策略在边缘统一下发，并可按站点灵活组合。WAF, IP allow/deny lists, rate limiting, CC defense and JS Challenge — delivered uniformly at the edge and composed flexibly per site.
证书与 DNSCertificates & DNS
支持手动上传证书，或通过 ACME 自动签发和续期；同时支持 CNAME Target 及多家 DNS 服务商授权。Manual certificate upload, or ACME auto-issue & renewal; plus CNAME targets and credentials for multiple DNS providers.
日志分析Log analytics
提供访问、缓存、回源和高可用日志，以及探测与审计能力；日志分析可选接入外置 ClickHouse。Access, cache, origin-pull and HA logs, plus probing and audit; log analytics optionally connects to an external ClickHouse.
节点运维Node operations
支持 cdn-agent 签名升级、配置实时下发与节点本地缓存容错，并提供健康心跳、备份恢复和操作审计。Signed cdn-agent upgrades, live config push with node-side cache tolerance, plus heartbeats, backup / restore and operation audit.
开发者接口Developer interfaces
提供 REST API、API Token 和 OpenAPI 3.0 规范，并支持边缘规则、脚本模板和用户 Edge KV。REST API, API tokens and an OpenAPI 3.0 spec, with edge rules, script templates and user Edge KV.

02 · 系统架构Architecture
请求面、主控与数据面相互独立Request, control and data planes — kept separate
主控负责统一编排和配置下发，边缘节点独立承载业务请求。即使节点与主控暂时断连，也可继续使用本地缓存配置提供服务；运行日志则单独汇入日志分析数据面。The control plane orchestrates and distributes config, while edge nodes serve requests on their own — and keep serving from locally cached config even when briefly disconnected. Operational logs flow into a separate 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 optionally flow into external ClickHouse for log analytics

03 · 应用场景Use cases
高度灵活的架构，轻松适配各种业务场景A highly flexible architecture that adapts to any business scenario
以下为 FunCDN 的典型应用场景，均由现有产品能力组合实现。完整场景及对应能力请查看应用场景页。A few representative FunCDN scenarios, each composed from existing product capabilities. See the use-cases page for the full set and the capabilities behind them.
自建 / 私有化 CDNSelf-hosted CDN
使用自有服务器和带宽承载内容分发。主控与节点均部署在自有网络中，配置和日志无需离开内网。Deliver content from your own servers and bandwidth; the control plane and nodes sit inside your own network, so config and logs never leave it.
多源站容灾Multi-origin resilience
源站池通过负载均衡和主动健康检查识别故障，并自动切换至可用源站；还可部署回源中继，作为备用回源链路。Origin pools use load balancing and active health checks to detect failures and switch automatically to a healthy origin; an origin relay can also be deployed as a backup origin route.
页面级高可用Page-level high availability
可为关键站点配置高可用规则。主站不可用时，浏览器按顺序探测备用地址并跳转至首个可用站点；全部备用地址均不可达时，再展示离线页面。此功能适用于增强版和定制版。Attach HA rules to critical sites: when the primary is unavailable, the browser probes backup addresses in order and redirects to the first reachable one, showing an offline page only if none respond. Available in the Enhanced and Custom editions.

06 · FAQ
常见问题Frequently asked
以下列出常见问题摘要。有关部署、授权、配额、高可用、日志分析和旧版本兼容的完整说明，请查看常见问题页。A summary of the questions we hear most. For the full explanations of deployment, licensing, quota, HA, log analytics and legacy compatibility, see the FAQ page.
FunCDN 采用什么部署方式？What deployment model does FunCDN use?
FunCDN 采用私有化、自建部署。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，以及常驻在各主机上的 cdn-agent。所有组件原生运行在您自己的 Linux 服务器上，由主控统一编排。FunCDN uses private, self-hosted deployment. A system includes the control plane (API service and web panel), edge nodes, an optional origin relay, and a resident cdn-agent on each host. All components 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?
页面级高可用仅向增强版和定制版开放；全功能版可看到功能入口，但使用时需升级。该能力仅针对页面导航请求进行容灾切换，并非对站点全部子资源进行透明接管。查看高可用工作原理 →Page-level HA is available only in Enhanced and Custom; the Full edition shows the entry but requires an upgrade to use it. It performs failover for 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?
授权配额按节点数与 Zone 数量计算。一个 Zone 对应一个根域名，同一根域名下的子域名统一归入该 Zone，不额外占用配额；实际配额上限以授权文件为准。Licensed quota is counted by node count and number of Zones. One Zone maps to one root domain, and subdomains under that root domain all belong to the same Zone and use no extra quota; the actual limits come from your license file.
