IPTV流量带宽计算

1、流量带宽计算1各节点带宽需求计算单播带宽：根据用户模型表,计算得出每个节点的单播带宽.信令带宽：根据各节点组网计算得到每个节点信令带宽.直播带宽：1如果是全网组播,那么每个节点只需要计算一份直播带宽,如50个H264频道,为2M x 50 =100Mbps.2如果是组播中继,那么：中央节点带宽与下挂的区域中央边缘节点个数有关,为n+1的关系.如：某中央节点下挂3区域中央,那么带宽需要计算 3+1=4份.区域中央带宽与下挂的边缘节点个数有关,为n+1的关系.如：某区域中央节点下挂12个边缘节点,那么带宽需要计算12+1=13份.每个边缘节点需要一份直播带宽,如50个H264频道,为2M x 50

2、 = 100Mbps.3如果是全网单播,那么：中央节点和区域中央节点计算方法与组播中继相同.边缘节点带宽需要根据用户访问模型计算本节点直播用户数获得.如某边缘节点带用户10000个,H264频道50个,根据用户访问模型,有 1850直播并发访问.那么需要的带宽为：2M x 50+ 2M x 1850 = 3800Mbps ,其中2M x 50为中继来的直播频道带宽.汇总获得每个节点的接入带宽需求：节点带宽=单播带宽 +直播带宽 +信令带宽2带宽计算实例在计算之前先通过查看 FRST解频道码率、用户数、频道数等参数.在线率和并发率和哪些部件有关系 在线率：EP舂量并发率：HM酷能根底带宽计算Bi
