Virtual Conference Server (VCS) & Access Point Server (APS)

Nefsis software includes virtual conference server (VCS) and access point server (APS) components. These components can be installed on a single physical server using our installation wizard, or custom-configured to run on separate machines in support of large-scale operations.

Server hardware

  • Intel Intel® Core™2 Duo processor, 2.0GHz or better
  • 2GB RAM for each server component (APS & VCS)
  • 4GB hard drive space for each server component (APS & VCS)
  • 2 static IP addresses (can be mapped or physical, but must be static)

Server software

  • Windows Server 2003 or later
  • Dot NET Framework 3.5 installed with the latest updates

Virtualization Environments

  • One dedicated CPU or CPU core
  • 2GB RAM available for Nefsis server components (APS & VCS)
  • 4GB of available hard drive space for each Nefsis server component (APS & VCS)
  • Dedicated network card
  • Windows Server 2003 SP3 or Windows Server 2008
  • Dot NET Framework 3.5 installed with the latest updates
  • 2 static IP addresses - One for each Nefsis server component (APS & VCS)

Note: Organizations can consider splitting the APS and VCS components onto separate servers to load balance the operating system resources and traffic on the network card. In this scenario, each server will use their main IP address provided no existing web server is running in Windows. An example of a web server is IIS (World Wide Web Publishing service) or Apache.

Network Requirements

Below are the requirements for setting up a Nefsis Dedicated server.

  • APS: TCP ports – 80 (HTTP) and 443 (HTTPS)
  • VCS: TCP Ports – 22, 23, 80, 443, 1270, and 37000 are highly recommended

For internal online meetings where all users are located behind the corporate firewall, we recommend the server have at least 10 Mbps of upstream and downstream bandwidth to all participants.

For meetings with a mix of users, some behind the firewall and others connecting over the Internet, we recommend at least 6 Mbps of upstream bandwidth to the Internet users. Higher Internet bandwidth is preferred.
