SUMMARY

Strong QA networking testing experience on switching, edge routing, and network management in

high performance carrier grade platforms. Extensive knowledge of IP network technologies in Layer 2 protocols

VLAN(802.1q), QinQ tunneling, STP/RSTP/MSTP, LACP and trunking, Layer 3 routing protocols like OSPF,

RIP, BGP, and Authentication protocols such as RADIUS server for AAA services in B RAS. Domain and host

protocols like DNS, DHCP, and VPN services using MPLS and IPSec/IKE, to tunnel IPv4/IPv6 traffic.

Automated test cases using PERL and test tools like IXIA N2X and Spirent to conduct functional, scaling,

loading, and performance tests. Experienced in testing emulated virtual devices in KVM in Linux server. Earned

QA award on defect identification, reproducing & solving.
