As a sampling, our staff has participated in the following
projects, implementing a wide variety of solutions:
Network Analysis and Monitoring Software
Enhanced software-only protocol analysis application
running under UNIX, Windows, WindowsCE platforms with
object-oriented protocol decode modules for TCP/IP, SNA,
OSI, IPX, AppleTalk, DECnet, Banyan stacks (data-link-level
to application-level), SNMP, VOIP, Wireless, Security
applications, Frame Relay, ATM, HDLC etc.. Implemented
an RMON MIB-compliant agent. Created tools for visualizing
multi-dimensional statistics of network traffic in a distributed
SNMP-manageable Telephone Switch
Ported an SNMP agent onto an embedded digital
telephone switch running under the VRTX operating system
. Designed a proprietary MIB for configuring and maintaining
switch resources. MIB dispatch functions and internal system
modules were implemented in C++.
Voice over Frame Relay
Implemented proprietary Voice over Frame Relay
protocol state machine
for embedded VxWorks environment.
Interoperability testing with
third-party equipment. Completed
product is shipping.
SNMP/RMON-based extensible data collection
Designed and implemented data collection module for
SNMP-based network monitoring product.
Completed collection modules
for RMON and RMON-2
statistics, protocol and application-layer host
Implementation is in C++ on Windows NT.
Similar application was developed for a switch using JAVA. It
also included displaying of data
in different types of charts
OSI on STREAMS
Implemented a US GOSIP-compliant OSI stack (datalink,
network, transport) as System V STREAMS pseudo-drivers.
A standard BSD socket and System V TLI library provided
the transport-level API.
Communications Drivers for an Intelligent
Signaling Protocols for ATM Switches
Implemented a new set of protocols using non
associative signaling on variety of switches including FORE
SX-200, GCNS and MINT (AT&T proprietary). Designed this
protocol to be hardware independent and to facilitate
transparent connections across heterogeneous switches.
Also developed video conferencing and video servicing
interface for demonstrating usefulness of signaling protocols
ISDN Layer 2 and Layer 3, Q.921 and Q.931
Designed and developed ISDN (Q931-user) layer 2 and
layer 3 on CTOS platform, which is a client-server-based
operating system. Developed tools for automated
conformance testing at the user end. Developed and
implemented system test scripts for Q931 using IDACOM
(now HP) PT-300 analyzer. Automated user-end scripts using
the conformance tester program developed. Also designed
MIB database for SNMP to work with layer 3 and layer 4.
IP over ATM
Created TCP/IP network over FORE switches which
allows IP traffic to go over ATM lines using SPANS signaling
and proprietary signaling. Release maintenance of TCP/IP
for 3B2 for AT&T.
Object Oriented GUI Tools for Network Management
and Monitoring Products
Network Implementation and Evaluation
Evaluation and Di-installation of LAN/WAN Networks,
including Routers and Bridges. First hand experience with
Bay Network's routers, using T1, using SNMP for querying
MIB database. Using Lan analyzers for protocol trouble
Web Based Client Server Products
Designed and developed
implemented over company's Internet/
Intranet. This web based tool allows the users to access the
using their Internet browsers. The application
reads the incoming data and dynamically creates HTML
which is sent back to the user's browser. This Client
Server application uses ODBC to connect to the Data Server.
