Dear All, In enclosed the document talked about my Network Diagram. (http://www.mediafire.com/?04523crqd2w57qj) The document is Vietnamese, let me explain: - We have 2 kind of User, Advance User and Basic User. + User will upload/download to/from FTP server through address: 188.8.131.52+ Each User has own Home Directory, mean Advance User will list a directory on FileServer1 (192.168.100.22: Computer, Windows 2008) and Basic User works on FileServer2 (192.168.100.33: Computer, Windows 2008)+ Actually we configured Network LoadBalancing FTP clustering (using windows 2008) and the address of them is FTP1.nlblab.local-192.168.100.2 and FTP2.nlblab.local-192.168.100.3. The virtual ip address of loadbalancing is 192.168.100.99 * The problem of my company: Please make 80% bandwidth for Advance User and 20% bandwidth for Basic User using QoS. (of course we are applying tomato/linksys WRT54GL) * BTW, in fact, if we don't user QoS, how can we make Advance User down load/up load faster Basic User. I tried step by step of http://www.linksysinfo.org/index.ph...orial-and-discussion.28349/page-6#post-138585 but It don't match my problem. Please help me and thank you in advance, Trung Nguyen.
