For ISPs like RENU, ensuring high availability is crucial to maintaining uninterrupted services. Here are some strategies for achieving network redundancy: Redundant Internet Links: Establish multiple internet links from different providers or routes. Implement BGP (Border Gateway Protocol) for dynamic routing to automatically switch traffic to the backup link if one goes down. Load Balancing:

Network security is a top concern for Tier 3 ISPs like RENU, as cyber threats can disrupt services and compromise data integrity. Here are some essential practices to enhance network security: Firewalls and Intrusion Detection/Prevention Systems: Deploy robust firewalls and intrusion detection/prevention systems to monitor and filter incoming and outgoing traffic. Regularly update rule sets

Ping Plotter This is a tool used by the RENU community to troubleshoot network issues. Once an institution is facing problems they are prompted to share their results with the NOC for interpretation. The big question is do you understand these graphs. This write-up covers the basic features of the graphs and their interpretation. You\’ve
Optical Bypass Switches A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active network device such as an intrusion prevention system (IPS), next-generation firewall, network switch etc. if the device loses power, experiences a software failure, or is taken off-line for updates or upgrades, traffic can no longer flow
