[$] More accurate congestion notification for TCP 更准确的 TCP 拥塞通知机制 AccECN 即将在 Linux 内核 7.0 版本中默认启用。这一机制改进了 TCP 协议中显式拥塞通知（ECN）的精度，有望提升公共和私有网络中的流量传输效率。 AccECN 通过更精细地反馈网络拥塞状况，帮助 TCP 连接更及时地调整数据传输速率，从而减少延迟和丢包。该功能已在过去几个内核版本中逐步引入，7.0 版本将默认开启以供广泛使用。 原文链接：https://lwn.net/Articles/1058666/ #网络协议#Linux内核#TCP#ECN #AIGC Read more
