TTLproblem
TTLproblem refers to a common issue encountered when dealing with Time To Live (TTL) values in networking and distributed systems. TTL is a mechanism that limits the lifespan of data in a computer network or a system. In the context of networking, TTL is a field in the IP header that determines the maximum number of hops a packet can take before it is discarded. If a packet's TTL reaches zero before reaching its destination, it is dropped, and an Internet Control Message Protocol (ICMP) "Time Exceeded" message is usually sent back to the source.
In distributed systems, TTL is often used for caching mechanisms. For instance, DNS records have a TTL
The "TTLproblem" can arise in several scenarios. In networking, it might manifest as packets not reaching their
