# 什么是聚合边缘
多 CDN 统一调度与管理：把 Cloudflare、CloudFront、EdgeOne、ESA 等多家边缘组织成一个整体，按地区和运营商、可用性和性能调度流量，某家 CDN 故障时自动切走
AxisNow 聚合边缘（Multi-Edge）是多 CDN（Multi-CDN）的统一调度与管理平台：把多家边缘提供商组织成一个整体，统一调度流量、统一管理配置、统一观测，让您的网站、应用和 API 不再依赖任何一家边缘。
## 带来什么
### 更快
访客走当时表现最好的一家边缘。
### 更安全
攻击流量由多家边缘分摊，降低单家被打穿的风险。
### 更稳
一家边缘故障时自动切到其他家，通常数分钟内完成。
### 更省事
在一个控制台管理所有边缘。
## 核心功能
多边缘流量调度、集中配置管理和统一观测。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://www.axisnow.io/zh/docs/multi-edge/overview.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
