General

What is this High-Speed Science Network

Tulane University’s High-Speed Science Network (HSSN) is an upgrade to the Tulane campus network providing researchers speeds of up to 10 gigabits per second directly to their labs and offices.

How can I access the HSSN?

Access to the High-Speed Science Network is granted by the Tulane Science DMZ Steering Committee. The first round of network drops installed will be based on a list compiled following a university-wide solicitation. Future access will require an application to be submitted to our Steering Committee.

If selected to receive an HSSN network attachment a network port will be installed in your office or lab and you will be given a 10GbE Network Interface Card (NIC).

Please review the minimum workstation system requirements to determine if a hardware upgrade will be required.

Technical

What are the minimum system requirements?

Unless you have a high-performance workstation chances are your hardware is not immediately compatible with the HSSN. Users may need to upgrade their systems to include a disk system capable of transfer speeds over the standard 1 Gigabit per second. The 10GbE network enables speeds of up to 1.25 Gigabytes per second. Standard SATA hard drives see speeds of around 150 Megabytes per second, or about 1/10th of the available HSSN bandwidth.

The following is a list of must-haves for your system:

  • A workstation with an available PCIe 2.0 x8 slot
  • 10GbE Network Card
  • Storage system capable of high bandwidth transfers
    • Single SSD drive
    • Array of SATA/SSD disks
What software is necessary to leverage the HSSN?

Traditional file transfer protocols do not support the increased bandwidth available to users on the HSSN.

There are two programs commonly used to move large datasets over high-bandwidth networks:

Both your local workstation and the remote data source will need matching software.

How can I verify HSSN speeds?

Several network performance diagnostics tools will be available to test connectivity speeds.

  • perfSONAR-PS The pS-Performance Toolkit is a downloadable, pre-configured collection of network performance tools, including NDT, BWCTL, OWAMP and perfSONAR tools and services.
  • Bandwidth Test Controller (BWCTL) BWCTL is a command-line client application and a scheduling and policy daemon that wraps Iperf and Thrulay.
  • Network Diagnostic Tool (NDT) NDT is a user-friendly client/server program that provides network configuration and performance testing to a user’s desktop or laptop computer.
  • One-Way Ping (OWAMP) OWAMP is a command-line client application and a policy daemon used to determine one-way latencies between hosts.

For additional information regarding the use of these tools, please contact [email protected].

Can I connect to the HSSN with an Apple computer?

Yes. Apple computers can connect to the HSSN provided they have a Thunderbolt port and an external network card.

Security

Can my HSSN workstation be physically connected to the Tulane Enterprise Network simultaneously?

No. Your HSSN workstation may only connect to the Science DMZ. You will be able to securely connect to the Tulane Enterprise Network resources through the HSSN via Tulane’s VPN. This will allow you to access both the Science DMZ and the Tulane Network with a single HSSN hardwired connection. That is, you will be able to access applications such as HCM, Banner, Kronos, and Gibson through the Science DMZ.

If VPN access to Tulane services is too restrictive, there is an alternate form of access involving firewall rules. This configuration will only be used in special cases.

Can I access resources on the Science DMZ from outside the network?

Yes, services within the Science DMZ will be available outside the network.
