8.4 FRTS
說明: 在幀中繼網絡中,如果不同的網絡段帶寬不匹配,往往會使網絡段的交界處產生瓶頸.如果192K 端向64K 端大流量
發送報文時,會在幀中繼網絡與64K 鏈路連接處產生瓶頸發生擁塞,導致無法正常傳送數據.因此,在DTE 端應用流量×××
機制,DCE 端應用擁塞管理機制.當網絡空閒時,用戶可以以大於CIR 在圖中CIR 爲32K 的複用帶寬,當網絡發送擁塞
時DCE 端會通知DTE,網絡已經發生了擁塞,DTE 端會通過流量×××調整發送速率,使DTE 出接口的發送速率降爲32000
以緩解DCE 端的擁塞狀況,使通訊正常進行.而且在DTE 端應用流量×××,可以向用戶提供承諾信息速率(CIR).當網絡空
閒時,用戶可以以大於CIR 的速率複用帶寬;當網絡發送擁塞時,用戶仍然可以以CIR 的速率發送數據.

Pc 的設置:
Server 的網關設置爲172.31.1.2
PC-Client 1 的網關設置爲192.16.1.2
PC-Client 2 的網關設置爲193.16.1.2
結果:
在Server 上啓動ftp 服務,同時在PC-Client 1 端啓動ftp 客戶端軟件如cuteftp 或flashget,並開始下載Server
上的大文件,在DUT 上應用FRTS 後,客戶端下載速率逐漸變小,逐步收斂於64k 左右.
