Confidential

Responsibilities:

• As a lead engineer, worked on gathering requirements from Confidential .
• Designed framework for integrating RDK components like Media Framework, Media Streamer and Media Player into the emulator.
• Developed an application (RMF Player) using RDK Media Framework components( Sources and Sinks) for emulating 4 modes of operation (Headed Gateway, Headless Gateway, Media Client with Confidential and Media Client without Confidential )

Confidential

Responsibilities:

• Implemented Multi Channel HDLC feature.
• Implemented IPv6 header Replace, IP header Swap and UDP port Swap features.
• Implementation of ECMP filter feature for equal distribution of data traffic.
• Winpath related field issue support and analysis involved in the contribution.

Confidential

Responsibilities:

• Developed ECmP Filter to distribute traffic uniformly between multipath destination endpoints.
• MAC Swap Feature implementation for a specific packet with expected VLAN, the packet is captured and VLAN header is replaced and MAC address is swapped.
