Lee -- System Building |
Led or Participated in
the following system building:
- IPv6 Edge Router prototype with wireless and optical interfaces.
- ONMP (Optical Network Management Protocol): An all-optical
network management system for the Lambda Router networks.
- LIP (Lambda Interworking Protocol): An interworking protocol
for Lambda Products: Lambda Router, Unite, and Xtreme.
- ITIS (Interoperability Testing Intelligent System): A software
system for automatic test generation for integrated systems interoperability
testing. The main objective of the technique is to obtain complete
test sets yet without redundancy. The software system incorporates
efficient algorithms for test generation. It contains a Graphic
User Interface (GUI) for inputting system specification modules
and for downloading and displaying generated test sequences. It
has been applied to VoIP user end, H.223, and Q.931 interoperability
testing.
- SOCRATES: A software system for IP router testing. It checks
the correct construction of routing tables, router packet forwarding
behaviors, and router database information consistency with the
network topologies in real time. It is based on probabilistic
algorithms with a high fault coverage. It contains a Graphic User
Interface (GUI) for monitoring the test execution.
- ROMA (Router Operation Management Agent): A software system
for IP router testing with the same functions as SOCRATES except
that it tests an IP router on-line, that is, it is connected to
the Internet and is in operation.
- PYTHIA: A software system for automatic generation of test
cases for systems modeled by state machines. The main objective
of the technique is to achieve desired coverage criteria with
a minimal number of tests. The tools incorporates a set of algorithms
that address different types of system models and coverage criteria.
It contains a Graphic User Interface (GUI) for inputting system
specification modules and for downloading and displaying generated
test sequences. It has been used successfully for the test generation
for various Lucent products.
- Feature testing of AT&T-Lucent PHS - a Wireless, 5ESS based
ISDN Personal Handyphone System - a product sold to Japan (4Q95).
Developed and implemented efficient algorithms for the test generation
and built software tools. Test sequences generated were used for
testing the product.
- Automatic Test Generation for DIAMOND. Diamond Access System
provides telephony service via the TL1 operations interfaces,
a major project under development at Lucent. There was a large
number of devices, called objects, to be tested and a manual testing
was proved to be time consuming, expensive, and unreliable; furthermore,
given the project schedule, it would be impossible to conduct
a thorough test manually. We developed software tools, including
a GUI, for automatic test generation that was being used by DIAMOND.
We also provide tests for robustness testing and system validation/verification.
- FBI finger print classification project. Developed and implemented
a segmentation technique to process the digitized finger prints
for upper level classifications.
- Feature testing of INAP 5ESS (AT&T/Lucent No.5 Electronic
Switching System). Developed and implemented an efficient procedure
for INAP testing, and built software tools for the test sequence
generation.
- POSTMAN: It was a general software tool for test generation
for systems modeled by finite state machines and was widely used
within Lucent.
- Test sequence generation for ATM Protocols - ABR and PNNI.
Model ATM protocols and generate tests for Standards through ATM
Forum, joint project with National Institute of Standards and
Technology.
- NCR bar code processing. Developed and implemented a new method
for bar code processing based on sparse samples.
