IGM - Integrated GNSS Master                                                                                     

Description:

Skill Set                        : C, C++, LINUX, IPv6, DHCPv6, Kernel Routing Tables, Ixia.

Responsibilities             : Development and Testing

Working for product called IGM (Integrated GNSS Master) & TP4100 (Time Provider) solution for Timing synchronization. This product is being used in telecommunication devices where timing precision is required in terms of Nano seconds, example base stations. Timing Synchronization is achieved by using protocol PTP as per IEEE-1588V2 standard from Satellite/Master Clock. My work involves mainly on developing the following features in above products:

• Enabling Management to support IPV6 in both VLAN& NON VLAN modes & Setting up   DHCPV6/DHCPV4 server for simulation in private network.
• Introduced nearly twenty CLI Commands and respective call backs to support IPV6 Configuration to the management interface.
• Backup & Restore
• ZTP Configuration
• Remote logging facility on IPV6 Interface
• Maintenance

2. IGMP - Multicast Routing in DPU                                                                          

Description:

Skill Set                        : C, C++, LINUX

Responsibilities             : Development and Testing

Igmp snooping process in DPU operates between CPE and NNI. DPU featuring IGMP snooping derive useful information by observing IGMP transactions. Based on the Subscriber Member Ship Join and Leave messages IGMP performs the data path establishment and removal operations with Network Processor. Igmp forwards the Group Specific Query/General Query to downstream to get the status of existing CPE's.  Igmp gets configuration information from the PMA and creates the data base for Subscriber Profiles,EVC, EVC MAP and interfaces.Igmp in turn maintains the stats of number of joins/leaves/General or group specific query information.

Handling Customer issues in various components like HostRM, StorageRM, Hags, ConfigRM and Topology service in RSCT.  Maintaining the customer issues and creating the awareness to the team. In solving the customer issues, developed memory leak tool for AIX to solve the memory leak issues and also used extensively dbx tool for debugging core dumps. Solving performance issues as well.

Skill Set                        : C/C++/AIX/Linux

Responsibilities             : Support

10. Call processing in ASN Gateway (WiMAX)                                                          

Description:

SSLC is a component in ASN Gateway. This component will maintain the mobile context details when  mobiles enter into the network.SSLC handles the functionalities like,Autheticating the mobile, paging, giving the lease to Ap when mobile gets bearer data, Updating the Mobile details’ when mobile has the new data, Handover procedure, and taking the lease from the AP.            

Once the mobile comes into the idle mode, SSLC will indicate the SSProxy to start monitoring data. This Component is developed in TAU G2 provided by the Telelogic.

Platform/Protocols        : TAU, C and Linux / Mobile IP

Responsibilities             : Development and Testing
