城市中的CATV用户(68%) = 81,600
节点 = 城市中的光纤节点总数 = 120

US (上行)信道带宽 = 1.6 MHz
USDR = US QPSK 数据速率= 2 Mbps

CASE
• 设计预期
所有用户都将在Web上冲浪
预期渗透(10%) = 12,000
每节点的预期用户= 100
每节点用户数= 每节点最大有效用户数(25%) = 25
DSAT = 每有效用户的最大DS有效时间 = 25%
USAT =每有效用户的最大US有效时间 = 25%
MDSDR = 每用户的最低DS数据速率= 270 Kbps
MUSDR =每用户的最低US数据速率= 40 Kbps
www.cisco.com
19
CASE
• 设计计算
可能用户/DS = DSDR/(DSAT * MDSDR) = 400
可能用户/US = USDR/(USAT * MUSDR) = 200
可能用户/DS (使用1x4 LC) = 200 x 4 = 800
限制在该例中为DS数据速率
有效用户/DS = 400
节点/DS = (用户/DS)/(用户/节点) = 400/25 = 16
所需DS通道 = 节点/(节点/DS) = 120/16 = 大约8
所需的uBR 7246机箱,带有8个1x4 LC = 8/4 = 2

• Each CPU module contains network processing element, DMA engine & memory
• Parallel pipelines amplify available processing power to 32X single CPU
• Memory access phasing between pipelines enables conflict-free sharing of I/O
ports and column memories
• Each CPU performs a separate section of the header processing operation
• Each CPU executes a fixed length computation on its current context All CPUs
switch from current context to new context in lockstep
