ASM流量调度套件支持通过QuotaSchedulingPolicy实现指定请求调用配额下的请求优先级调度。当系统中正在处理的请求速率超过指定的配额时，后续的请求将会被排队，同时优先级高的请求能够被更快处理。本文介绍如何使用流量调度套件提供的QuotaSchedulingPolicy来实现请求调用配额管理。
背景信息
QuotaSchedulingPolicy通过令牌桶算法来控制调用指定服务的请求速率，并在速率超过指定配额时对请求进行排队处理。大致工作流程如下：
使用限流器对请求进行速率限制：使用令牌桶算法对请求进行限流，有关限流器的算法实现，可详细参考使用RateLimitingPolicy实现分用户限流场景的背景信息。
请求调度：请求速率超过配额限制后，后续请求将会被排队，等待先前请求处理完成后再发送给服务，以保证请求速率始终保持在给定数值。同时，高优先级的请求有更大的机会被从队列中取出发送给服务。
和限流的场景不同，使用QuotaSchedulingPolicy时，若请求速率超过限制，此时请求不会被直接拒绝，而是进入一个优先级队列，在保证请求速率始终在限制内的同时对请求进行优先级调度。
前提条件
已添加Kubernetes托管版集群到ASM实例，且ASM实例为1.21.6.95版本及以上。具体操作，请参见添加集群到ASM实例。
已通过kubectl连接至ACK集群。 具体操作，请参见获取集群KubeConfig并通过kubectl工具连接集群。
已开启ASM流量调度套件。具体操作，请参见开启ASM流量调度套件。
已为Kubernetes集群中的default命名空间开启自动注入。具体操作，请参见管理全局命名空间。
已创建名为ingressgateway的入口网关，并开启80端口。具体操作，请参见创建入口网关。
已经部署httpbin应用，并且可以通过网关访问。具体操作，请参见部署httpbin应用。
步骤一：创建QuotaSchedulingPolicy配额管理规则
使用kubectl连接到ASM实例，具体操作，请参见通过控制面kubectl访问Istio资源。
使用以下内容创建quotaschedulingpolicy.yaml文件
apiVersion: istio.alibabacloud.com/v1 kind: QuotaSchedulingPolicy metadata: name: quotascheduling namespace: istio-system spec: quota_scheduler: bucket_capacity: 10 fill_amount: 10 rate_limiter: interval: 1s scheduler: workloads: - label_matcher: match_labels: http.request.header.user_type: guest parameters: priority: 50.0 name: guest - label_matcher: match_labels: http.request.header.user_type: subscriber parameters: priority: 200.0 name: subscriber selectors: - service: httpbin.default.svc.cluster.local部分配置项说明如下。关于配置项的更多信息，请参见QuotaSchedulingPolicy CRD说明。
配置项
说明
fill_amount
在interval指定的时间间隔内填充令牌的数量。示例中指定为10，即每过interval指定的时间间隔后便向令牌桶填充10个令牌。
interval
向令牌桶中填充令牌的时间间隔。示例中指定为1s，即每过1秒后便向令牌桶填充10个令牌。
bucket_capacity
令牌桶内的令牌数量上限。当请求速率小于令牌桶填充速率时，令牌桶内的令牌数量会持续增加，最大将达到
bucket_capacity。使用bucket_capacity可以容许一定程度的突发流量。示例中设置为10，和fill_amount相同，即不允许任何突发流量。workloads
根据请求header中的
user_type定义了两类请求，分别是guest和subscriber。guest类型的请求优先级是50，subscriber类型的请求优先级是200。selectors
指定应用限流策略的多个服务。示例中使用httpbin.default.svc.cluster.local 服务进行并行度限制。
执行以下命令，创建配额管理规则
kubectl apply -f quotaschedulingpolicy.yaml步骤二：测试请求配额管理效果
本步骤使用压测工具fortio进行测试，安装方式请参见安装fortio。
同时打开两个终端，并分别运行下面两个压测命令（尽可能同时开始这两个测试），整个测试期间，请确保不要关闭对应的终端。两个测试都使用10并发、10000预期QPS的设定对服务发起调用，远远超过了服务的预期并发度限制。
fortio load -c 10 -qps 10000 -H "user_type:guest" -t 30s -timeout 60s -a http://${ASM网关IP}/status/201fortio load -c 10 -qps 10000 -H "user_type:subscriber" -t 30s -timeout 60s -a http://${ASM网关IP}/status/202说明请将上述指令中的
${ASM网关IP}替换为ASM网关的IP地址。有关获取ASM网关IP地址的具体操作，请参见使用Istio资源实现版本流量路由。测试1的预期输出：
