• Cons • O(N^2) in control plane / O(N) in data plane • Poor in scheduling algorithm • Iptables rules are difficult to debug IPVS mode • Services are organized in hash table • IPVS DNAT • conntrack/iptables Size limitation of BPF program is one million after Linux 5.2 Lessons from eBPF • Too strict check in eBPF verifier • Example: s64 bpf_csum_diff(__be32 * from, u32 from_size, __be32 * to, u32 to_size);

mode • 在netfilter pre-routing阶段做DNAT • 在netfilter post-routing阶段做SNAT • 每个service 添加一条或多条rules。使用数组管理rules。 • 仅支持随机的调度算法 • kube-proxy代码实现比较简单 • iptables 在linux 已经广泛部署 优势 iptables mode 不足之处

Snowpark 有活跃的社区、丰富的可用库和工具，这使其对开发者非常具有吸引力。 89. fast-check 试验 fast-check 是一个为 JavaScript 和 TypeScript 设计的基于属性的测试工具，它能够自动生成测试数据，从而无 需创建不同的测试即可仔细检查各种输入，这使得它更容易发现边缘场景。 我们的团队在后端测试中使用 fast- check 取得了不错的结果，归功于它良好的文档、易用性以及与现有测试框架的无缝集成，单元测试的效率得
