I'm currently looking at some network design's for small business about 500 users. This is just for my degree so not a real situation. Firstly for a network this small. Is a distribution layer really needed? I was thinking with only 500 users the normal processing that would be conducted by layer 3 switches in the distribution layer could be moved to the core. With the core consisting of a virtual server running web apps etc but also conducting the inter VLAN routing etc. Im dubipous on the scaling of this method but am intersted in looking into it from a cost effective solution. Any one got an software names that will give me a start. Iv found Vrouter by Vyatta. will this interVLAN routeing etc form a virtual server on to actual physical switches? Any software names, hits will be appreciated. Im just a noob learning. Iv found Vrouter by Vyatta. will this interVLAN roouter etc form a virtual server on to actual physical switches?
