Cisco Systems

Software Engineering R&D Intern

• Performance improvement of PPPoE Client Emulation on ASR1k Series Aggregation router: Fine-tuned the PPPoE emulation module, which helps in generating PPPoE control packets at the much faster rate that eventually improves the Calls per second(CPS) at higher number of sessions. Made use of Image Profiling Tool called Flamegraph to identify the execution times of datapath functions
• Hosting TRex application as a container on ISR4k router for sending PPPoE encapsulated packets: Hosted a realistic Traffic Generator (TRex) inside a container over ISR4k router, which can be used to send the PPPoE sessions traffic through TRex inside the container on ISR4k router, thus acting as a virtual Traffic Generator, instead of relying on third party expensive traffic generators like Spirent & Ixia, as being used by Cisco for generating traffic over router
• TRex On UCS Box: Incorporated & successfully tested the role of virtual realistic Traffic Generator App (TRex) on the Cisco’s Unified Computing System (UCS) & monitored the link speed through GUI App of TRex on UCS as Client & ASR1k as Server
