Further Testing of TRILL (TRansparent Interconnection of Lots of Links) Christina Dube

The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its second TRansparent Interconnection of Lots of Links (TRILL) Interoperability Test Event the week of May 20 - May 24, 2013 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together implementers of TRILL as well as test equipment manufacturers that support TRILL. The purpose of the test event was to gain a perspective on the current status of TRILL implementation and interoperability. Participants included Extreme Networks, Hewlett-Packard Networking, Huawei Technologies, and Ixia.

High Speed Digital Subscriber Line - Second Generation ANSI T1.418-2000 Start-up Phase Test Suite Stephen Scapicchio

InterOperability is becoming increasingly important in today?s communication industry. In a time when the consumer has more choice and flexibility in their home networking and Internet services than ever before, single vendor solutions are nearly impossible and most definitely impractical. For this reason manufacturers are taking every precaution to make sure their products work properly with all other manufacturers? products. In this spirit standards bodies are formed with the claim that modems will work collectively if they adhere to the approved standard. However, as with all documents the standards are open to interpretation. This test suite will ensure complete activation phase compliance of a High Bit Rate Digital Subscriber Line- Second Generation modem. The tests are designed to scrutinize the modems adherence to American Nation Standards Industry?s Ti.418-2000 High bit rate Digital Subscriber Line- 2nd Generation (HDSL2) approved standard. All anticipated results are based on this document and the validity of the anticipated results can be proved using this document. The methods of testing are as low level as possible and do not rely on a specific vendor?s product so the most accurate and unbiased results may be obtained.

Implementation and Comparison of iSCSI Over RDMA Ethan Burns

iSCSI is an emerging storage network technology that allows for block-level access to disk drives over a computer network. Since iSCSI runs over the very ubiquitous TCP/IP protocol it has many advantages over its more proprietary alternatives. Due to the recent movement toward 10 gigabit Ethernet, storage vendors are interested to see how this large increase in network bandwidth could benefit the iSCSI protocol.

In order to make full use of the bandwidth provided by a 10 gigabit Ethernet link, specialized Remote Direct Memory Access hardware is being developed to offload processing and reduce the data-copy-overhead found in a standard TCP/IP network stack. This thesis focuses on the development of an iSCSI implementation that is capable of supporting this new hardware and the evaluation of its performance.

This thesis depicts the approach used to implement the iSCSI Extensions for Remote Direct Memory Access (iSER) with the UNH iSCSI reference implementation. This approach involves a three step process: moving UNH-iSCSI from the Linux kernel to the Linux user-space, adding support for the iSER extensions to our user-space iSCSI and finally moving everything back into the Linux kernel. In addition to a description of the implementation, results are given that demonstrate the performance of the completed iSER-assisted iSCSI implementation.
