- Deep Packet Inspection , implemented and maintained application detection and policy control, Individual applications can be dropped, rate limited and time-based policy can be set.
- Custom Application classification and sending start and stop events for a particular application.
- Client Isolation , within VLAN’s clients don’t talk to each other except gateway. Many modes of isolation have been implemented, dynamically learning gateway and statically adding mac address, this feature extended to clients connected behind the wired side.
- L2GRE , tunnel redundancy state machine has been implemented to have a failover concentrator.
- Dual L2GRE Support , AP can have two l2gre tunnels to each unique concentrator simultaneously, could be one ipv4 and pv6 tunnel or any IP combination.
- Support GRE over UDP and propriety CambiumGRE to use GRE tunnel behind the NAT.
- Auto VLAN , responsible for implementing AP code, authenticates the AP to switch and pushes the VLANs configured on AP to switch port automatically.
- Added PPPOE feature, by which Access Point can connect to ISP and get authenticated from it.
- Added NAT logging feature for Chinese customers as they not using a syslog server.
- Added VLAN grouping feature for big organizations like Universities, where they accommodate large numbers of clients on a single WLAN . This feature assigns clients with VLAN from vlan pool, derived from using round-robin algorithm.
- Guest Access VLAN dependency , this involves removing VLAN dependency to redirect the wireless Client VLAN traffic to AP till guess access authentication happens.
- Lead Engineer in automation and development for integrated network setup deployment for cambium products cnpilot, cnpilotxirrus access points and wireless controller
- Feature experience - DHCP, DNS, VLAN, CAPTIVE PORTAL, GRE tunnel, MESH networks, TCP/IP.
- Developed QA efforts with next generation python framework 'Pytest' to setup wireless and wired infrastructure with real clients.
- Integrated CI/CD pipeline with Jenkins to control the build release by testing and publishing the enhanced reports.
- Built automation team and leading them in successfully delivering the product to customer and clients.
