IPTV流量带宽计算

1、文档名称流量带宽计算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，则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，则：中心节点带宽与下挂的区域中心（边缘节点）个数有关，为n+1 的关系。如：某中心节点下挂3区域中心，则带宽需要计算 3+1=4 份。区域中心带宽与下挂的边缘节点个数有关，为 n+1 的关系。如：某区域中心节点下挂 12个边 缘节点，则带宽需要计算 12+1=13 份。每个边缘节点需要一份直播带宽，如50个H

2、264频道，为 2M x 50 = 100Mbps 。3）如果是全网单播，则：中心节点和区域中心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，按照用户访问模型，有 1850直播并发访问。 则需要的带宽为： 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 FRS了解频道码率、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：
