10 ，cilium github 项目已有 9.3K star，Contributors 316位 cilium的特色功能： • 网络功能 • 负载均衡 • 网络安全 • 可观察性 • 多集群连通 注：本 PPT 基于 cilium v1.10.4 进行分析 ��������������� ��������������� �������������������� �������������������� 、 sendmsg、 recvmsg 、getpeername 、 bind等系统调用，实现 service 的地址解 析，并且伪装通信目的地址，让上层应用 无感知 DNAT 的发生 效果： • 集群内访问nodePort、LoadBalancer 的service时，能够减少数据包转发跳 数，极大提高网络性能 • 相比传统 iptables 等 技术，降低了访 问延时。例如在相同环境下，service 发生变化， 整集群可能需要同步 信息，刷 新 OVS 流表或者 ipset 规则 • 大规模的 policy ，会一定程度 的影响规则查询的效率，会一 定程度的影响规则更新的时间， 这些都会引入的TPS波动 Cilium policy采用了 identity 标识来进行 L3 - L4 policy 决策。 • 根据Cilium endpoint 的 label， 计算生成集群唯一的identity，意味着

request has a GET/POST/PUT/DELETE methods (opera�on) and URLs (resource).

For example, for MySQL traffic on port 3306, you could run the following in a container running the MySQL client or server: “tcpdump -s 0 port 3306 -w mysql.pcap”.
