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 graphical environment.

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 next-generation SNMP-based network monitoring product. Completed collection modules for RMON and RMON-2 statistics, protocol and application-layer host groups. 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 and tables.

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 Software Switch

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 over ATM.

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 shooting.

Web Based Client Server Products

        Designed and developed Office Resources Management System implemented over company's Internet/ Intranet. This web based tool allows the users to access the application using their Internet browsers. The application reads the incoming data and dynamically creates HTML output, which is sent back to the user's browser. This Client Server application uses ODBC to connect to the Data Server.
