Course Introduction：现代家庭通常有多个设备同时连接Wi-Fi访问网络，这常常导致带宽紧张，尤其是在进行在线游戏或视频流媒体等高带宽需求活动时。 为了帮助您管理网络负载，一些路由器（例如Google、Netgear、Eero等厂商生产的路由器）提供了一种名为“服务质量”（QoS）的功能。 Simply put, it allows you to prioritize specific devices and traffic types on your Wi-Fi network so that those devices and traffic can prioritize high-speed connections when bandwidth is limited. Your router vendor may use a different name to call this feature, but a quick lookup of the instructions or searching online should determine if your router provides QoS capabilities

Course Introduction：Port forwarding is a technology that transfers external network requests to local devices, and is commonly used in home networks to realize external network access. Its core function is to allow the router to allow specific traffic to be transmitted to a device in the LAN through a specified port, solving the problem that the external network cannot actively connect.主要应用场景包括远程访问NAS、搭建游戏服务器、查看监控摄像头、提升下载速度等。 The settings steps are generally: 1. Log in to the router management page; 2. Find port forwarding or NAT settings; 3. Add rules to specify external ports, internal IP and protocol types; 4. Save and restart the router according to the situation.注意事项包括：使用静态IP、避免知名端口、确认有公网IP、配合防火墙、定期检查规则，建议用完即删以保障安

Course Introduction：要实现可靠的Go服务重试机制，应使用带抖动的指数退避，先明确答案：1.采用指数退避加随机抖动避免请求洪峰；2.封装可复用的重试函数并支持上下文控制；3.设置最大重试次数与退避上限；4.优先使用成熟库如cenkalti/backoff/v4；5.避免对404等永久错误重试并记录重试日志。 A complete implementation requires these core steps to improve system flexibility.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
