➢ Design, implementation and automation of l2 forwarding features➢ Design, implementation and automation of TCAM based ACLs based on different flexibleprofiles.

➢ Design, implementation and automation of policy model for various networking features in ACI fabric which includes the following:✓ Defining the logical model in XML which is accessible directly via REST API’s for programming the ACI fabric. ✓ Implementation of policy manager on APIC to validate the logical model and resolve the logical model into a simpler model and push it to the applicable leaf/spine switches as per the configuration in REST API’s, CLI or GUI.✓ Defining the concrete model in XML which is used for programming ASIC on leaf/spine switches based on the simpler logical model pushed to leaf/spine switches.Implementation of policy element code which creates and modifies objects based on concrete model and send notification to NxOs for programming ASIC on leaf/spine switches.✓ Implementation of faults in policy element by validating configuration for concrete objects which are pushed back to APIC.✓ Implementation of CLIs on APIC as an alternative way to program the ACI fabric via logical model.

➢ Design and implementation of Parser for the software simulator of the XPliant product family based on XPA (XPliant Packet Architecture). ➢ Design and implementation of Parser Configuration and Initialization Modules as part of software development kit (SDK).➢ Design and implementation of Parser Configuration data and user interface which generates input for Parser Configuration.➢ Participated in design and implementation of bridging module software development kit (SDK).
