For testing purposes, Multi Server Simulator simulates large, virtual HTTP, FTP, SMTP, or DNS server networks, as well as SNMP-based network switches using a standard Windows PC. It is an indispensable tool for the evaluation and testing of network management and network testing tools.

Create Virtual Test Networks In Minutes

Using a standard Windows PC you can create large virtual networks using Multi Server Simulator. You are able to create as many servers and virtual switches as desired - limited only by the number of available IP addresses and TCP ports (as well as network and system performance).

Available Virtual Device Types:

  • SNMP based switches (with 8, 100 or 1000 switch ports each)
  • HTTP server
  • FTP server
  • SMTP server
  • DNS server
  • Simple server (open TCP port that accepts connections)

Setting up a network 100 servers and 20 switches (with thousands of ports) network merely takes a few minutes, much faster than installing and configuring normal server software on a PC.

How to use Multi Server Simulator

The program will automatically discover all available IP addresses on the local machine. Select an IP address and click on one of the protocol buttons to add a virtual server. It will show up in the tree view on the right, beneath its IP address. Click a server to go to the configuration settings. When done with the configuration enable the "Up/Down" checkbox to start the server.

Features

  • For all server/switch types:
    • Name and TCP/UDP port can be set as desired for each server
    • Servers can be created and deleted, as well as turned on and off with a single mouse click
    • Recurrent downtimes can be simulated (for each device, intervals can be set by user)
    • Detailed log is written for each simulated server
    • Server sets can be saved to a XML file and reloaded later
  • SNMP Switch:
    • Simulates a SNMP manageable switch (according to RFC 1643 and RFC 1155)
    • Simulates switches with 8, 100 or 1000 ports
    • The traffic counters for each port are constantly updated to simulate data passing through the virtual switch
    • For the 8-port switch, the type of traffic pattern simulation can be set
  • HTTP Server: The web server always answers with one of two HTML blocks (intervals and repetition can be set by the user)
  • FTP Server: Simulates an FTP server that accepts login requests and sends the number of available files
  • SMTP Server: Accepts SMTP protocol connections with and without authentication
  • DNS Server: Resolves DNS requests for the DNS name "localhost" with IP address 127.0.0.1; other DNS names cause an error message
  • PORT: Accepts TCP connections on the specified TCP port
  • Works on 32-bit and 64-bit versions of Windows Vista, 2008, 2012 and Windows 7, 8
