近期,Mica-MQTT 1.3.9 版本正式发布,本次更新修复了一个重要的 Bug,即 MQTT Client 在 QOS2 消息重试机制中的问题。QOS2 是 MQTT 协议中的一种消息服务质量级别,它要求消息必须被至少传递一次,但最多只传递一次。然而,在之前的版本中,由于重试机制的实现存在问题,导致在某些情况下,QOS2 消息可能会出现重复传递...
RabbitMQ提供了一种qos(服务质量保证)功能,即在非自动确认消息的前提下,如果一定数目的消息(通过基于consume或者channel设置Qos的值)未被确认前,不进行消费新的消息。 启用Qos和手动Ack可能导致队列阻塞: 如果consumer接收到消息后没有ack或者unack,并且使用Qos限制了prefetch数量,当unacked消息太多就会造成堵塞 应答方式:...
Computer science Client-based QoS monitoring and evaluation architecture for network infrastructure and services WESTERN MICHIGAN UNIVERSITY Ala Al@Fuqaha KamelAmmar MohammedProviding an efficient Quality-of-Service (QoS) measurement model is a challenging problem in today's mobile computing and ...
Client-side QoS monitoring allows mobile clients to participate in the service evaluation process. Through this approach, mobile clients play proactive role to collect and measure network parameters (e.g., delay, bandwidth) and report any potential service degradation back to the service providers. ...
先创建一个qos client:import qos from 'qos-node-client'; // const qos = require('qos-node-client').default; const appId = '66666666'; const secretId = 'hello world'; const secretKey = '你好,世界'; const bucket = 'demo'; const client = qos.createClient({appId, secretId, secretKey...

QOSStopTrackingClient 函式會通知 QoS 子系統停止追蹤先前使用 QOSStartTrackingClient 函式的用戶端。 如果流程目前正在進行中,此函式將不會影響它。
