Collaborate with customers and cross-functional teams to translate the user requirements and use cases into appropriate network solutions and associated deliverables.
Define and develop criteria for evaluating and selecting Wireless Platforms/Solutions.
Execute the test plan and publish a comparison report among participating OEMs.
Integration of OEM platforms with Client Prod Tooling stack for Fault, Configuration, Accounting, Performance & Security (FCAPS).
Wireless platforms release management
o Create a comprehensive list of use cases/scenarios to be tested.
o Review reports provided by manufacturers, including release notes, dependencies, caveats, and affected bugs, and update guidance accordingly.
o Track new features on OEM Roadmap.
o Track critical open issues and fixes with OEM TAC.
o Track open security vulnerabilities and fixes.
o Define an upgrade cadence and rollout plan for production. Coordinate the upgrades in validation lab (ie. Validation Chambers and WLCs) and prod rollout.
o Setup/write automated Wi-Fi tests for Continuous Integration(CI) and release validation (bug scrub).
o Provide support and guidance to wireless network operations team for troubleshooting (Client and Network side) critical issues and L3 escalations.
o Participate in the development and improvement of processes, metrics, tools, alerting, and scripts to optimize network performance and ensure reliable operations. This includes identifying opportunities for automation and solutions that enhance monitoring capabilities, streamline processes, and reduce human error.
o Proactively contribute to and maintain technical/training documentation. - Network Design and Planning: Developing detailed network architecture plans incorporating IPv4 and IPv6 addressing schemes to accommodate current and future network requirements, to meet organizational needs and future growth. Using protocols such as BGP/MP-BGP, EVPN VXLAN and OSPF for efficient and scalable network routing.
- Installation and Configuration: Navigating difficult issues in supporting existing deployment teams involving a strong technical, strategic and collaborative approach. Setting up network devices with advanced protocols features BGP/MP-BGP, EVPN VXLAN. DHCP, supporting both IPv4 and DHCPv6 for IPv6. Configuring DNS for resolving domain names to both IPv4 and IPv6 addresses. Implementing stateful and stateless firewalls to control incoming and outgoing network traffic based on predetermined security rules.
- Assessment and Planning: Conducting a thorough analysis of the existing networks. Developing a detailed migration plan, including timelines, resource allocation, and risk assessment. Creating comprehensive documentation for both the legacy and new networks. Configuring new hardware and software according to the design specifications. Performing rigorous testing to ensure functionality, performance, and compatibility. Executing the migration plan with minimal disruption to ongoing operations. Coordinating with cross-functional teams to manage dependencies and resolve issues promptly.
- Maintenance and Support: Using SNMP/NetFlow/sFlow/ICMP/syslog for monitoring and managing network performance. Regularly updating firewall rules and configurations to protect against emerging threats. Monitoring the old and new network to ensure stability and 3 performance. Providing pre and post-migration support for old and new network architectures. Troubleshooting to address any complex issues that arise.
- Security Management: Implementing security protocols such as IPSec for secure network communications in both IPv4 and IPv6 environments. Employing RADIPi servers for centralized authentication.
- Work with multiple Client teams to perform setup, configuration, and testing in lab and pre-field environments of networking solutions in support of validation and acceptance testing phases.
