/p17_1.jpg) ## MOSN 做业务扩展 • 扩展非 xDS 服务发现 • 扩展 L4/L7 filter • 扩展 Xprotocol 支持 • Debug 及 Admin 管理 • Metrics 监控统计 ## Envoy 复用基础能力 • 复用高效 Eventloop 模型 • 复用 xDS 服务元数据通道 • 复用 L4/L7 filter • 复用 Cluster 008d0093b2ada802e5bf/p23_1.jpg) MOSN 和 Envoy 的相关服务元数据信息，是如何交互管理的？ 通过扩展 Envoy 中的 Admin API 使其支持 xDS 同等功能的 API，MOSN 集成的 Service Discovery 组件通过该 API(rest http) 和 Envoy 交互 使其 MoE 的服务发现能力也具备“双模”能力，可同时满足大规模及云原生的服务发现通道 Copy  - 同时具备云原生 xDS、REST API服务元数据管理通道能力 - MOSN/GoLang 和 Envoy 生态拉通 实现多个社区技术共享，增强 Service Mesh、Dapr 等领域的生态 ## MOE 实践介绍

is Apache ActiveMQ Artemis? - Apache ActiveMQ Artemis is an open source project to build a multi-protocol, embeddable, very high performance, clustered, asynchronous messaging system. - Apache ActiveMQ war="console.war"> #### 2.2. 0 Full release notes. Highlights: - Scheduled messages with the STOMP protocol. • Support for JNDIReferenceFactory and JNDIStorable. - Ability to delete queues and addresses different vendors cannot directly interoperate since each will use the vendor's own internal wire protocol. Apache ActiveMQ Artemis provides a fully compliant JMS 1.1 and JMS 2.0 client implementation.

• Pilot-agent进程本身创建UDS接收Envoy连接，用于证书更新下发。并且与istiod建立证书更新通道。 Envoy 通过pilot-agent转发机制与istiod建立长连接，通过xDS协议接收系统下发的监听器、路由、集群节点等更新信息。 ### • 3. 数据面通信 • 客户端请求进入容器网络，并被iptables规则拦截，经过DNAT后进入Envoy virtualOutbound监听器 REDIRECT（DNAT）保存原始目标地址后，进入Envoy的15006端口。 ## Envoy启动配置及xDS  |xDS|描述|模式|请求路径| |---|---|---|---| |LDS|监听器配置|POST|/envoy.service c96f433fb7/p11_1.jpg) ## • 分为Envoy主线程及worker线程: ## • 主线程： • 负责初始化Envoy并读取解析配置文件 启动gRPC监听器，并启动xDS变化监听 启动日志写入线程，每个目标日志文件有独立线程负责输出 启动concurrency数目的工作线程 启动看门狗线程监控各个工作线程是否定期touch，否则SIGABRT杀掉线程 启动admin

Apache ActiveMQ Artemis provides a fully compliant JMS 1.1 and JMS 2.0 API. ## System specific resources, e.g. PUT, POST, GET etc. REST approaches to messaging often use HTTP as their underlying protocol. The advantage of a REST approach with HTTP is in its simplicity and the fact the internet is already
