Experience Firmware Engineer
Spirent Communications
01.2005 - 05.2011
- Primary responsibility includes design, development and maintenance of features on TestCenter (Phoenix) product line which include multiple CPUs and embedded OS over a system
- All projects here are developed in C++
- Designed and developed soft watchdog (keep alive) to track the test unit running status
- Designed, developed and maintained the Generator daemon which is the core daemon used to generator traffic to measure performance of device
- This includes protocol, traffic scheduling algorithm and stream based protocol configurations
- The challenging part was to implement protocols to test other protocols with large scalability and precision
- Integrate firmware with new generation of TestCenter card with new architecture.
Firmware Engineer
Spirent Communications

- Primary responsibility includes design, development and maintenance of generating, analyzing and capture traffic to measure the performance of device on Terametric product line
- Designed and developed IPv6 protocol support, includes Neighbor Discovery and Router Discovery
- The major responsibility was creating durable database for large scale testing
- Written in C and Linux environment
- Designed and developed the IGMP V3 and MLD V1 and V2 protocol
- The feature was to simulate 20k clients per port for protocol testing on DUT
- The large scalability and thread safe would be important in this project
- Written in C and Linux environment.
Quality Assurance Software Engineer
Spirent Communications
01.1999 - 01.2001
- Created test framework and test script to validate the quality and performance of the feature and the system
- The test needs to have clear understanding on the Ethernet and TCP/IP protocol
- The script is written in Visual Basic and TCL
- Work along with the development engineers as white box test to confirm the feature to bring up new product line Terametrics
- The test is written in TCL and C.
