To address this issue, the cryptography community has been working on a new class of cryptosystems known as post-quantum cryptography (PQC), which are expected to withstand quantum attacks but can be less efficient (in particular, communication bandwidth wise) than its classical counterparts.

This means a system that is not merely available but is also engineered with extensive redundant measures to continue to work as its users expect. reliability situations, where continuity of service is essential, with redundant elements continuously in-service, such as with airplane engines. This ensures reliability.

Occasionally, customers report issues such as high latency or not achieving their subscribed bandwidth. To address these concerns, we certify the last-mile connection using iPerf3 for traffic and bandwidth analysis. Are GRE tunnels the best solution in this scenario, or would another tunneling or routing protocol be more effective?

If BFD identifies a failure in the bidirectional channel connecting two forwarding engines, which includes interfaces and data links, the member link is deleted from the forwarding table. Users can configure BFD across the primary port-channel interface to monitor LAG bandwidth utilization via a mini BFD session for each member.
