- Design, implement, and manage the Mobile Packet Backbone Network (MPBN), ensuring its scalability, security, and optimal performance.
- Configure and maintain routers, switches, and network elements involved in the mobile packet core infrastructure.
- Ensure high availability and reliability of mobile backhaul services, managing traffic routing, load balancing, and capacity planning for mobile data services.
- Perform detailed network performance monitoring, including traffic analysis and fault detection, to ensure the MPBN operates with minimal downtime and maximum efficiency.
- Configure and optimize network protocols (e.g., OSPF, BGP, MPLS, VPN).
- Troubleshoot and resolve network issues related to IP routing, MPLS, QoS (Quality of Service), VPNs, and other critical network functions.
- Collaborate with cross-functional teams (e.g., core network, transport, and access teams) to integrate and optimize new technologies within the MPBN.
- Implement and maintain network security best practices for the backbone network, ensuring data integrity, confidentiality, and access control.
- Coordinate with vendors and other external parties for hardware/software upgrades, patch management, and configuration changes to maintain the health of the MPBN.
- Participate in the planning and deployment of new features, services, and technologies within the MPBN.
- Create and maintain detailed network documentation, including network designs, topology maps, IP address plans, and configuration guidelines.
- Provide on-call support and troubleshooting for MPBN issues as required.
