JuniperM10i路由器的QoS配置示例.doc

Juniper M10i 路由器的QoS配置示例一、QoS策略标准按目前QoS的现有分类标准（缺省VPLS分类器、缺省IP优先分类器、缺省MPLS分类器、缺省DSCP分类器、缺省IEEE 802.1p分类器、缺省IEEE 802.1ad分类器），由于各厂家品牌不同，同一品牌型号不同，同一型号操作系统版本异样，且各厂家采用标准不一，QoS代码实现也不尽相同。因此，云南铜业（集团）有限公司在云铜信息系统基础建设技术标准V3中采用DSCP值与IP优先级对应的方式，定义了集团公司网络中通用的QoS分类值如下：QoS策略业务类别优先级要求DSCP值IP优先级适应队列语音应用高CS55LLQ视频应用高CS44CBWFQ关键应用低CS33CBWFQ办公及其它应用无缺省值缺省值CBWFQ注：QoS指Quality of Service，即服务质量。 VPLS指Virtual Private LAN Subnet，即虚拟专用LAN子网段。 MPLS指Multi-Protocol Label Switching，即多协议标签交换技术。 DSCP指Differentiated Services Code Point，即差分服务代码点。 LLQ指Low Latency Queuing，即低延迟队列。 CBWFQ指Class-Based Weighted Fair Queuing，即基于类的加权公平队列。 PLP指Packet Loss Priority，即包丢失优先级。为确保视频会议数据的流畅，公司提供如下路由器的QoS配置示例，仅供参考。请大家根据各自路由器类型及操作系统版本，制订适合自己的QoS代码实现。二、M10i路由器QoS配置示例#配置Forwarding class的queue，配置每个queue的名字和优先级。class-of-service forwarding-classes queue 7 fcNetwrok priority high; queue 5 fcVoice priority high; queue 4 fcVideo priority high; queue 3 fcKeyApp priority low; queue 0 fcDefault priority low;#定义每一个的queue的Classifier。class-of-service classifiers inet-precedence precClassifiers forwarding-class fcNetwork loss-priority high code-points 111; forwarding-class fcNetwork loss-priority low code-points 101; forwarding-class fcVoice loss-priority high code-points 101; forwarding-class fcVideo loss-priority high code-points 100; forwarding-class fcKeyApp loss-priority low code-points 011; forwarding-class fcDefault loss-priority low code-points 000 001 010 ; #配置RED的Drop-Profile的Fill-Level、Drop-Probability。class-of-service drop-profiles dropVoice interpolate fill-level 50 75 100 ; drop-probability 1 50 100 ; dropVideo interpolate fill-level 40 70 100 ; drop-probability 1 50 100 ; dropKeyApp interpolate fill-level 30 65 100 ; drop-probability 1 50 100 ; dropDefault interpolate fill-level 20 60 100 ; drop-probability 1 50 100 ; #定义Rewrite-Rules。class-of-service rewrite-rules inet-precedence rrMarkPrec forwarding-class fcNetwork loss-priority high code-point 111; forwarding-class fcVoice loss-priority high code-point 101; forwarding-class fcVideo loss-priority high code-point 100; forwarding-class fcKeyApp loss-priority low code-point 011; forwarding-class fcDefault loss-priority low code-point 000; #配置Schedulers的传送速率，Buffer-size，优先级，drop-profile-map。class-of-service schedulers schNetwork priority strict-high; schVoice transmit-rate percent 5; buffer-size temporal 5000; priority high; schVideo transmit-rate percent 75; buffer-size temporal 20000; priority high; schKeyApp transmit-rate percent 5; buffer-size temporal 5000; priority low; schDefault transmit-rate percent 10; buffer-size temporal 10000; priority low; drop-profile-map loss-priority low protocol tcp drop-profile dropDefault; #配置Schedulers-Map。class-of-service scheduler-maps schmapNetwork forwarding-class fcNetwork scheduler schNetwork; forwarding-class fcVoice scheduler schVoice; forwarding-class fcVideo scheduler schVideo; forwarding-class fcKeyApp scheduler schKeyApp; forwarding-class fcDefault scheduler schDefault; #在端口上应用Schedulers-Map，IP的Classifiers和Rewrite-rulesclass-of-service interfaces so-0/0/0 scheduler-map schmapNetwork; unit 0 classifiers inet-precedence precClassifiers; rewrite-rules inet-precedence rrMarkPrec; #设置过滤器Firewall Family inet Filter filVideo Term term1 From Source-address 10.160.201.0/24;Then forwarding-class fcVideo;Then accept;Term term2 Then forwarding-class fc
