|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.

|Design, Implementation, and Evaluation of a Fibre Channel Driver for IP on Linux||Vineet M. Abraham||
Fibre Channel, which is used for high-speed data transfers, supports several higher layer protocols including Small Computer System Interface (SCSI) and Internet Protocol (IP). Until now, SCSI has been the only widely used protocol over Fibre Channel. IP over Fibre Channel had not been successful mainly due to inadequate specification in the standards. Currently IP specifications have reached a stage where interoperable implementations are possible. Although some support does exist for SCSI on Linux, there is no support for IP on Linux. This thesis aims at designing, developing, testing and evaluating a Fibre Channel driver for IP on Linux.

|Ensuring Interoperability for Open Networking Systems||Christina Dube, Daniel Gray and David Woolf||
Open Networking has created new opportunities and new challenges for Data Center designers and implementers. Many customers are used to deploying monolithic solutions from a single integrator. When implementing Open Networking solutions from multiple providers, a few key questions arise: Will it all work? Are there common interfaces I can use to monitoring and control the hardware? How do Data Center designers and implementers ensure that the components they’ve chosen will be interoperable? Will the Open Networking Solution work as well as or better than a traditional monolithic solution?
