Software Defined Radio (SDR) Based Implementation of IEEE 802.11 WLAN Basedband Protocols Shravan Surineni

The IEEE 802.11 family of wireless LAN protocols defines multiple physical layers implementations of which direct sequence spread spectrum (DSSS, 802.11b) and orthogonal frequency division multiplexing (OFDM, 802.11a/g) are currently the most popular. Market pressures are forcing the convergence of multiple wireless protocols into the same access device, and shortened product design cycles dictate rapid prototyping of new or enhanced protocols. The computationally intensive signal processing algorithms and high data rates associated with these protocols necessitate dedicated hardware implementation of some portions of the signal processing chain, yet allocating separate hardware resources for each of the standards would make the "universal access device" bulky and inefficient. Re-using the same software-reconfigurable hardware to handle different processing algorithms would enable an efficient, flexible alternative to current prototyping and implementation methods. In this thesis, the feasibility of using Software Defined Radio architectures as a prototyping tool for wireless LAN baseband signal processor implementations is explored. Signal processing architectures and algorithms for DSSS and OFDM protocols were developed in the Simulink and Matlab environments, and were then translated to VHDL hardware descriptions. A reference design for a OFDM transmitter was synthesized for implementation on a Xilinx Virtex II FPGA, and functional and timing simulations verified the design correctness.

Super Demo 2004 MFA and MSF

SuperDemo 2004 was the product of a partnering of the Multiservice Switching Forum (MSF) with the MPLS & FR alliance. Eleven companies participated in expanded testing including advanced service provider applications. The collaboration of the MSF and the MFA took the meaning of success to another level in the industry. The Multi-Vendor MPLS infrastructure was constructed for stability and reliability. The Demonstration of VoIP services across this network clearly conveyed a feeling of resilience.

Testing Home Routers for World IPv6 Launch Timothy Winters

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 - April 20, 2012 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together both users and suppliers of CE routers, also known as home router equipment. The purpose of the test event was to gain a perspective on the current status of IPv6 interoperability against the Internet Engineering Task Force (IETF) Basic Requirements for IPv6 Customer Edge Routers and support the Internet Society (ISOC) World IPv6 Launch. The eight participating vendor companies tested a total of ten distinct home router implementations throughout the week using publicly routable IPv6 addresses. Participants included Broadcom, CHT-TL IPv6 Testing Lab, D-Link, NDM Systems, Motorola Mobility LLC, Netgear, Time Warner and ZyXEL.

Observations discussed in this paper include:
* DHCP Solicits Frequency
* Renumbering
* No Default Route
* Forwarding before Address Acquisition
* DHCPv6 IA_PD & IA_NA Interactions

Testing TRILL (TRansparent Interconnect for Lots of Links) Christina Dube

The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its second TRansparent Interconnect of Lots of Links (TRILL) Interoperability Test Event the week of November 26 – December 1, 2012 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 Hewlett-Packard Networking, Extreme Networks, Ixia and Spirent Communications.
