后端处理器处理新连接。 • 后端处理器在配置中指定处理协议，根据协议相关的网络过滤器处理读取到的数据。 • 如果为http协议，再经过请求过滤器处理http协议头部，如路由选择等功能并创建上游连接池 • 将修改及编码后的http消息通过网络发送到对端Envoy的容器网络。 • Iptables识别为入流量则进入virtualInbound端口。 • ORIGINAL_DST恢复原始目标后 http.router L7 HTTP过滤器 HTTP路由及负载均衡的入口点，作为L7层过滤器链中 最后一个过滤器。 监听过滤器 L4网络过滤器 L7 HTTP过滤器 L4网络过滤器 上游连接池 监听 下游连接 上游连接 Copyright © Huawei Technologies Co., Ltd.
