一篇介绍用 Swift 实现超高速 IPv4 地址解析算法的博客,通过新算法在 Apple M6 上以约 3 纳秒、15 个 CPU 周期完成解析,成果将贡献给 Swift 官方的 swift-networking-types 项目。
本播客采访了 DNS 之父 Paul Mockapetris,讲述了 DNS 诞生前的主机表时代、URL 反转命名与 www 前缀的设计缘由、DNS 的树状解析机制及其迁移互联网的过程。
ranet3 is a high-performance, standards-based (IKEv2, ESP, Babel, SRv6) policy-routed IPsec mesh SD-WAN tool. Benchmarks show it reaching 95% of 10 GbE line-rate throughput, 1.6–2.1× faster than in-kernel WireGuard.
一篇面向初学者的博客,介绍地址解析协议(ARP)如何把 IP 地址映射到 MAC 地址,并演示 arp-scan、Wireshark 和 ip neighbour 等工具的使用,顺带提及 ARP 欺骗与广播风暴等安全话题。
Ahmad 分享了如何通过 Mikrotik CRS804-4DDQ 1.6Tbps 交换机,将 4 条 400G QSFP-DD 拆分为 2x200G QSFP56,连接 8 台配备 ConnectX-7 的 DGX Spark,实现 1.6Tbps 全速互联的集群方案。
A short tweet asking for recommendations on the best way to connect four NVIDIA DGX Spark units without using a network switch, likely for an evaluation setup.
The DNS Museum 是一个收录各种奇特、富有创意但不实用的 DNS 玩法的参考网站,包含 49 个条目,涵盖利用 PTR 记录绘制 traceroute 图案、DNS over 各类奇异协议、DNS 隧道以及各种工具与玩具。
回顾性文章介绍 IBM 在1985年推出的 Token Ring 网络技术,它曾与以太网竞争,凭借无冲突和高负载下更稳健的优势一度表现优秀,但因成本更高、升级速度落后于以太网,最终在1980-90年代的“网络标准之争”中败下阵来,如今已成为被遗忘的技术古董。
作者介绍了 RFC8950,该标准允许在 IPv6 网络上以 IPv6 下一跳通告 IPv4 路由(无需隧道),使骨干网可以仅运行 IPv6 而将 IPv4 作为边缘可选功能,并给出了基于 FRR 和 Containerlab 的实验演示。
Flipflop is a Rust-based tool using Iroh to establish persistent trusted tunnels between devices, enabling file sharing over Bluetooth, LAN, or the internet, with builds for Linux, macOS, Windows, and Android.
Go 1.27 introduces significantly better HTTP/1 connection reuse in the net/http package, delivering nearly 5x faster performance for sequential HTTP/1 requests by avoiding unnecessary new TCP/TLS connection setup costs.
Blade 是一款 Product Hunt 上发布的产品,帮助用户从 Gmail 收件箱中挖掘已有联系人,通过筛选联系频率和最近互动,批量发送个性化邮件,用于产品发布、寻求反馈或活动邀请。
curl 8.23.0 引入多项性能优化,包括 base64 编解码、URL 编解码、日期和数字解析提速,以及约 40% 的结构体内存缩减和更少的内存分配。
NVIDIA 和 Cisco 联合推出可插拔光学模块(USFP),首次支持每通道 400Gb/s,带宽密度提升 4 倍,帮助 AI 数据中心在不增加网络层级的情况下连接更多算力并降低单位功耗。
在OCP全球峰会上,NVIDIA通过开源MGX架构向OCP贡献了Vera Rubin机架与计算托盘设计,并与Meta、Google、Cisco等合作伙伴发布了AI工厂开放标准、网络互连及800V直流供电等新进展,以推动全球AI工厂的规模化建设。
