新疆电信大城域网现状说明全疆共建设8大城域网：乌鲁木齐－吐鲁番－哈密大城域网，克拉玛依－阿勒泰－塔城大城域网、奎屯－博乐大城域网、昌吉－石河子大城域网、喀什－和田－克州大城域网，阿克苏、巴州、伊犁三个地州独立组网；8大城域网核心／汇接双挂ChinaNet和CN2上联ChinaNet链路：8大城域网核心／汇接兼做ChinaNet骨干接入节点，即大城域网出口设备和链路与ChinaNet接入设备和中继链路相同；上联CN2链路：8大城域网核心／汇接通过2.5G或GE电路与本地的CN2接入P路由器连接。8大城域网内部各跨地州的链路目前均采用1*2.5GPOS；Page36 新疆典型城域网SRCRBRASChinaNetCN2SR/ASBRPEP汇聚交换机DSLAMOLTADSLONU园区交换机楼道交换机OLTONU汇聚交换机/OLT分别上连至BRAS和SR，BRAS承载HSI业务，SR承载IPTV、网吧，专线以及NGN业务。目前IPTV使用IPOE接入方式，无认证，DHCPserver分配私网地址。大部分地市BTV和VOD均采用单播方式推送。少数地市（伊犁、奎屯）开了BTV组播。目前SR大多为NE80E。Page37 IPTV软件平台架构三级架构，省中心将BTV流量单播推送至市中心。当前采用从上海文广使用传输STM-1管道拉单播到省中心在开了组播的地市，市中心平台通过单播转组播服务器，作为组播源，起组播下发BTV流量。边缘节点作为热点VOD片源存储节点，命中大部分热点VOD请求。SRCR-NE5000EBRASChinaNetCN2SR/ASBRPEP汇聚交换机DSLAMOLTADSLONU园区交换机楼道交换机OLTONU省中心市中心边缘节点SDHSTM-1上海文广Page38 用户业务模型分析目前城域网已开展业务主要有HSI，大客户专线，专线上网，IPTV以及后期的VoIP。其中IPTV用户的开展情况：以伊犁为例说明，总共2万IPTV用户，业务类型只有BTV、VOD和PLTV，其中60%的单播，40%的组播。Page39 现网组播协议部署骨干网络：省中心部署在163上，暂时不考虑切到CN2。骨干网不起组播，通过单播推送BTV流量。城域网络：市中心平台作为组播源，CR作为RP，并部署AnycastRP。CR和SR起PIM-SM，三层组播通过SR终结并向下推送。接入网络：对于OLT接入，组播复制点放在OLT。大量用户接入DSLAM，复制点放在DSLAM上。其他情况复制点放在汇聚交换机上。分别在复制点配置组播VLAN和IGMPproxy以及二层组播静态加入。组播流量单层Q，单播流量两层Q（内层业务，外层DSLAM/OLTID），在SR终结QinQ。SRCRBRASChinaNetCN2SR/ASBRPEP汇聚交换机DSLAMOLTADSLONU园区交换机楼道交换机OLTONU省中心市中心边缘节点AnycastRPPIM-SMMVLANIGMPproxy组播组静态加入MVLANMVLANPage40 现网接入认证，地址规划现网IPTV采用IPOE接入方式，外置DHCPserver为STB分配私网地址。业务平台采用公网地址。整网IPTVVLAN统一规划，IPTV业务VLAN：3930；汇聚交换机组播VLAN：3938；DSLAM/ONU组播VLAN：3959。用户离线后IP地址资源回收。接入路由器的IPPool中IP地址的大小根据当地用户量、并发用户数和用户行为而定。用户行为指IPTV用户在收看完IPTV业务后，是否会把STB掉电。在STB可以释放地址的前提下，在DHCPServer端地址池设置一定的收敛比。Page41 端到端带宽分析新疆电信IPTV现阶段只有标清（H.2641.8M）,考虑到封装开销，以及组播的视屏增强（FCC、RET）带来的带宽增加，以下带宽估算将VOD、BTV均按照2.5M码流计算。以伊犁为例，2万用户，并发率50%，并发用户按1W计算。其中60%点播，40%直播。边缘节点命中率80%，组播频道150个。共2台SR，分担2万用户，SR到CR的带宽为：(20000*0.5/2)*0.6*(1-0.8)*2.5M+150*2.5M=1.875G（需要确认当前线网的链路模型？否则在新增ME60的情况下，部署GE会有问题？）每台汇聚交换机、OLT、DSLAM下挂的IPTV用户分别按2000、1000、200计算。Page42 端到端带宽分析复制点在汇聚交换机上：SR到汇聚交换机带宽：(2000*0.5)*0.6*2.5M+150*2.5M=1.875G汇聚交换机到DSLAM/OLT:DSLAM:(200*0.5)*0.6*2.5M+(200*0.5)*0.4*2.5=250MOLT:(1000*0.5)*0.6*2.5M+150*2.5M=1.125G（确认一下上行带宽的部署？）复制点在DSLAM/OLT上：SR到汇聚交换机带宽：(2000*0.5)*0.6*2.5M+150*2.5=1.875G汇聚交换机到DSLAM/OLT:DSLAM:(200*0.5)*0.6*2.5M+(200*0.5)*0.4*2.5=250MOLT:(1000*0.5)*0.6*2.5M+150*2.5=1.125GPage43 视频增强关键指标分析频道数150个SDTV，iVSE规格满足（IVSE支持大概在600~700个SDTV）。iVSE单板处理并发FCC请求数1.7K。现网以伊犁为例，频道切换并发率按50%计算。FCC最大并发请求数为20000*0.5*0.4*0.5=2000。两块iVSE卡即可。Page44 可靠性分析目前汇聚交换机只接入到一台SR（两台SR分担用户），存在单点故障风险。后续实验局考虑双挂方案，DR实现备份，同时配置BFDforPIM，加速故障感知和组播流量切换。Page45 实验局目标网新建ME60单独作为IPTV业务的接入网关。原有SR-NE80E承载大客户专线和NGN业务。原有BRAS仍只接入HSI业务。在IPTV业务网关上部署iVSE卡，实现FCC，RET及QoE（MDI，VMos）。部署U2520配合MQMC实现业务平台和承载网的统一质量监控及可视化运维。SRCRBRASChinaNetCN2ASBRPEP汇聚交换机DSLAMOLTADSLONU园区交换机楼道交换机OLTONU省中心市中心边缘节点IPTV业务网关：ME60-16已经到货Page46

实验局建议地点选择---两个维度考虑：1.选择现网已经起组播的地市；2.选择现网均为我司设备。实验局实施分阶段：为最大程度减小实验局对现网影响，可以考虑先割接组播业务，单播业务仍保留在NE80E上（单播VLAN和组播VLAN分别上行到不同网关）；同时只割接小部分汇聚交换机。IPTVES系统切换问题，割接过程中ES需要双挂（NE80E和ME60）。---确认NE80E的SR和ME60的站点问题，是否同机房？需要与客户交流光纤资源问题。（新增多条链接）建议部署两台ME60，避免单点故障。每台ME60部署2块iVSE卡。STB和IPTV平台版本升级，配合iVSE实现视频增加功能。Page48
