Work history
- Defined the technical direction:
Layer-2.5,
MPLS-based Ethernet
and
application-aware services
- Produced most of the product and feature
requirements, and coordinated technical issues between engineering
and sales teams
- Acted as the technology conscience for senior
engineering staff
- Worked with key customers and partners
directly
- Contributed technical proposals in various
standard bodies when time allows
- 2002 2004 (24 months), Principle
Engineer, Project Lead, Core Networking Division,
Ciena Corporation
- 2001 - 2002 (18 months), Member of
Technical Staff, Routing Group,
Juniper Networks
- Designed and developed a number of MPLS
scalability and redundancy features. Some of the deployed features
were
RSVP refresh reduction
(JUNOS 5.1), MPLS fast switch-over (JUNOS 5.3), and
RSVP-TE fast reroute
(JUNOS 5.4).
- Invented and designed the original
lsp-ping
(because its draft would include both of my first and last
names).
- Worked on the
PacketStar project on
traffic engineering and COPS
- Researched on scalable reservation signaling
mechanisms and UNIX operation systems (kernels).
- Researched on data networking: signaling
protocols (RSVP, SIP), QoS (IntServ,
DiffServ), network
policies (COPS)
and IP switching.
- Developed RSVP and DiffServ from scratch for
IBM router products.
- 1991-1995, Staff Engineer, Project Lead,
IBM
- Designed and developed the entire stack of
Frame Relay UNI/NNI, SMDS UNI and ATM PVC/DXI.
- Led a development team to help the deployment
of Frame Relay services to IGN.
- Built routers for
NSFNET and
IBM Global Network (IGN):
the last owner of T960 T1 and Ethernet that had powered NSFNET,
ANS and IGN.
