3. Network Design and Implementation Assistance
-Network Design Collaboration: Assist in the design, planning, and deployment of network solutions in collaboration with Network Architects or Senior Engineers.
-Implementation Support: Provide support in implementing network upgrades or new solutions, ensuring smooth integration and operation within existing infrastructure.
4. Network Optimization
-Performance Tuning: Monitor the network's health and performance and apply
appropriate tweaks or changes to optimize performance (e.g., configuring load balancing, adjusting QoS parameters).
-Bandwidth Management: Analyze bandwidth usage and optimize the network to ensure quality service for critical applications.
5. Security Management
-Network Security: Assist in managing network security tools (e.g., firewalls, intrusion detection/prevention systems) to ensure the network is protected from external and internal threats.
-Access Control: Implement and manage access control lists (ACLs), VPN configurations, and user access policies to ensure secure network usage.
6. Documentation and Reporting
-Documentation: Maintain accurate records of network configurations, network topologies, and changes made to the network.
-Reports: Generate performance, security, and incident reports for internal teams or clients to ensure proper follow-up and documentation.
7. Collaboration with Cross-functional Teams
-Vendor Liaison: Work closely with third-party vendors or service providers to resolve issues that may require external support or product replacements.
-Team Collaboration: Work with other IT teams (e.g., server, application, and security teams) to ensure seamless network operations in a multi-faceted IT environment.
8. Backup and Recovery
-Network Recovery: Assist in network disaster recovery planning, backup configurations, and provide support in case of a network failure or outage.
-Redundancy and Failover: Ensure that network redundancy (e.g., using HA pairs for switches or routers) and failover mechanisms are properly configured and tested.
9. Training and Knowledge Sharing
-Mentoring: Provide guidance and support to L1 engineers and junior staff, assisting with day-to-day troubleshooting and network operations.
-Continual Learning: Stay updated with the latest networking technologies, tools, and trends. Enhance personal knowledge and contribute to the team's knowledge base.
