理学 网络服务质量 释 differentiated service 区分服务 规定了一种简单可扩展的机制用于分类和管理网络流量，并在现代IP网络上提供服务质量（quality of service，QoS）的计算机网络架构。区分服务可以用于为关键的网络流量（如语音或者流媒体）提供低延迟，同时为非关键服务（如Web流量或者文件传输）提供尽力而为的服务。区分服务在IP报头中的8位区分服务字段（DS字段）中使用6位区分服务码点（differentiated services code point，DSCP）来进行数据包分类。DSCP字段和显式拥塞通知(explicit congestion notification，ECN)字段替换过时的IPv4的服务类型（type of service，TOS）字段。
