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.

RSP: Development of an 802.11 MAC Richard L. Lynch

In the growing world of ubiquitous networking, people often take for granted that interoperability exists between their network devices and the networks they are connecting to. Consortium vendors and international standards bodies are formed to establish standards on how devices should behave if they wish to communicate with each other. However, verifying conformance to these standards is no trivial task. The RSP was developed to add to the Wireless LAN Consortium's testing capabilities. The RSP has the capability of reacting to wireless traffic in a manner that tests a device's handling of uncommon, but very important conditions. The RSP Consists of an 802.11 MAC'less card from Intersil, interfaced to an Altera programmable logic device, which in turn communicates with a PC through a USB microcontroller.

Design and Implementation of a SCSI Target for SANs Ashish A. Palekar

The Small Computer Systems Interface (SCSI) has been used to transmit data between applications (Initiators) and storage devices (Targets). One of the major limitations of SCSI has been the length of the SCSI bus. With the evolution of Storage Area Networks (SANs), several protocols have been proposed to extend the length of the SCSI bus e.g., Fibre Channel, SCSI Encapsulation Protocol (SEP), and Internet SCSI (iSCSI). The evaluation of these technologies requires the use of an Initiator and a Target that implement the said protocols. A large portion of what such Initiators or Targets need to do from a SCSI perspective can be isolated into a logical code unit referred to as a mid-level. While there exists in the Linux kernel a generic SCSI Initiator mid-level that drivers written for various Initiators can interface with, no corresponding facility exists for the Target side. This thesis involves the development of a Generic SCSI Target midlevel for Linux along with implementing front-end drivers for Fibre Channel, SEP and iSCSI that can utilize the said Target mid-level. Other uses for the Target Emulator are as a bridge between two protocols and as an interface for SAN Management.

QOS Over ADSL Praveen Reguraman

Today's digital economy, dominated and driven by the growing commercial outlook of the Internet, has stimulated the demand for broadband networking as well as Quality of Service (QoS) architectures to achieve application performance and user satisfaction. Asymmetric Digital Subscriber Line (ADSL) is gaining prominence as a cost-effective broadband access solution for high speed Internet access, being widely deployed nationwide. The promise and potential to handle applications like Video on Demand over ADSL has set the stage to engineer and evaluate QoS in ADSL systems. As a first step in this direction, the various issues applicable to QoS over ADSL are discussed and a test setup was developed to evaluate the QoS metrics with respect to the physical layer characteristics of ADSL systems. The results of the preliminary set of experiments and the insight gained from these will be presented along with recommendations for future work.

Design, Implementation, and Evaluation of a Fibre Chanel 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.
