Technical Lead

Technologies: VPWS, VPLS, LAG, QoS, OSPF, BGP, MPLS, LDP/RSVP, ISSU Improvement

Responsibilities:

• Telstra wanted to modify the QoS profile attached to different services on the fly with minimal traffic impact
• Confidential provided solution by implementing a new feature with a team of 5
• QoS feature testing involving (Strict & Weighted QoS) carried out for this requirement by covering all the required services like L2 local circuits, L2 pwe3 circuits, VPLS Bridging Interfaces, LAG Bridging Interfaces, L2 pwe3 circuit bundles
• Unearthed ~ 20 bugs during the test cycle and delivered quality software during the development release
