Using a standard Windows PC, Multi Server Simulator can simulate large, virtual HTTP, FTP, SMTP, or DNS server networks, as well as SNMP-based network switches. The number of servers and virtual switches that can be created is limited only by the available IP addresses and TCP ports (as well as network and system performance). With Multi Server Simulator, setting up a large network of 100 servers and 20 switches (with thousands of ports) takes just minutes and is much faster than having to install and configure server software on a PC. For example if you want to test whether a SNMP management software is able to handle thousands of switch ports you can either monitor a few hardware switches multiple times (without knowing what side-effects that may have) or you can install Multi Server Simulator on one or more PCs and let it simulate many virtual switches with up to 1000 ports each. Multi Server Simulator is an easy-to-use, indispensable tool for the evaluation and testing of network management.
