  • Serial attached SCSI simulator aids design choices

    by Mikkel Hagen & Ryan Goulding, UNH-IOL

    Here’s a look at how a SAS simulator developed by University of New Hampshire’s InterOperability Laboratory  can scale enterprise storage area networks in the age of big data.

    Serial attached SCSI (SAS) currently uses an expander-based networking architecture. The expander acts as a pure port extender with no switching backplane involved, meaning there is minimal flow control and processing taking place. This architecture is severely limited for enterprises requiring larger storage area networks. In fact, once the number of connections starts to increase from tens and hundreds to thousands of connections, the entire network performance begins to decline.  Read More

  • The Connected Home Protocol

    by Lincoln Lavoie, UNH-IOL

    As tech-savvy individuals, it’s likely that we’ve all had a phone call from a family member or friend that usually begins with the obligatory compliment, “I know you’re good with computers, and I was hoping you could help me …” A few years ago, this type of call was more about helping our family member or friend find a file on their computer, but today the technical challenges have evolved. Now, the questions are more likely about connectivity within the home network.  Read More

  • Automotive Ethernet Conformance and Interoperability Testing

    by David Estes, UNH-IOL

    Can you give us a brief overview of automotive Ethernet?

    Automotive Ethernet is the use of Ethernet technology within the vehicle to connect systems that require a higher bandwidth than what is currently available.  The standard Ethernet frame format and point-to-point topology is preserved.  Read More

  • Testing home routers for World IPv6 launch

    By Timothy Winters, UNH-IOL

    The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its fourth IPv6 Customer Edge (CE) Router Interoperability Test Event the week of April 16 at its facility in Durham, N.H., bringing together both users and suppliers of home router equipment. The goal was to gain perspective on the current status of IPv6 interoperability against the Internet Engineering Task Force’s (IETF) Basic Requirements for IPv6 Customer Edge Routers and support the Internet Society’s (ISOC) World IPv6 Launch. Eight vendors — Broadcom, CHT-TL IPv6 Testing Lab, D-Link, NDM Systems, Motorola Mobility LLC, Netgear, Time Warner and ZyXEL — tested ten router implementations using publicly routable IPv6 addresses.  Read More
