8.4 FRTS
说明: 在帧中继网络中,如果不同的网络段带宽不匹配,往往会使网络段的交界处产生瓶颈.如果192K 端向64K 端大流量
发送报文时,会在帧中继网络与64K 链路连接处产生瓶颈发生拥塞,导致无法正常传送数据.因此,在DTE 端应用流量×××
机制,DCE 端应用拥塞管理机制.当网络空闲时,用户可以以大于CIR 在图中CIR 为32K 的复用带宽,当网络发送拥塞
时DCE 端会通知DTE,网络已经发生了拥塞,DTE 端会通过流量×××调整发送速率,使DTE 出接口的发送速率降为32000
以缓解DCE 端的拥塞状况,使通讯正常进行.而且在DTE 端应用流量×××,可以向用户提供承诺信息速率(CIR).当网络空
闲时,用户可以以大于CIR 的速率复用带宽;当网络发送拥塞时,用户仍然可以以CIR 的速率发送数据.

Pc 的设置:
Server 的网关设置为172.31.1.2
PC-Client 1 的网关设置为192.16.1.2
PC-Client 2 的网关设置为193.16.1.2
结果:
在Server 上启动ftp 服务,同时在PC-Client 1 端启动ftp 客户端软件如cuteftp 或flashget,并开始下载Server
上的大文件,在DUT 上应用FRTS 后,客户端下载速率逐渐变小,逐步收敛于64k 左右.
