Cilium KPR使用BPF map替代kube-proxy的iptables/IPVS,实现O(1)查找与原子更新。ClusterIP采用socket-LB,NodePort支持SNAT/DSR/Hybrid模式,Maglev用于南北向一致性哈希。排障需区分socket与per-packet平面,注意map容量、externalTrafficPolicy及混部冲突。
该文章介绍了Cloudflare的四层负载均衡方案Unimog,它是一种基于自定义硬件服务器的负载均衡器,采用了类似于Google的Maglev的技术选型。Unimog具有动态负载均衡的特性,可以根据机器负载自动调整连接数量。文章还介绍了Unimog的转发链路、连接保持技术和基于XDP的软件实现。控制面使用Conductor来生成转发表、进行健康检查和负载均衡。此外,文章还讨论了UDP的支持和特殊情况下的处理。
本文介绍了Google的Maglev四层负载均衡架构设计,包括转发架构、GRE封装技术、一致性哈希算法、VIP匹配、内核绕行和IP分片支持。Maglev的配置管理、运维经验分享和监控调试工具也被提及。性能评测结果表明Maglev具有优秀的性能。
V8通过引入新的中间层编译器Maglev和顶级编译器Turbofan的新架构Turboshaft,加快了HTML解析器和DOM分配速度。此外,V8还发布了JavaScript的新功能和WebAssembly垃圾收集WasmGC。在安全方面,V8专注于沙箱、模糊处理和CFI,并进行了一些规模较小但值得关注的工作。
本文重点描述Maglev一致性哈希算法,并提出使Maglev一致性哈希算法支持带权重候选节点的改进方式, 以及描述了一致性哈希下的动态负载均衡策略,并给出开源C++实现代码库。 一致性哈希 一致性哈希是一种将属于无限集的key稳定地映射到属于有限集的候选节点上的算法,它需要满足: 稳定:候选节点集合不变时,一个固定的key,会稳定不变地映射到某一个候选节点上; 最小扰动:当增加或减少候选节...
好久没博客了,来写个简单的读论文笔记吧,这篇文章是来自 Google 2016 年发表的一篇论文 Maglev: A Fast and Reliable Software Network Load Balancer 分享了他们内部从08年开始大规模使用的软负载均衡系统的实现。里面很多很有趣的细节,我看我能写多少,算多少吧
