Time is a factor permanently present in our lives. It can be stressful, but it’s an efficient way to organize and control different aspects. The idea of chaos sometimes sounds exciting, but being realistic, it’s not viable when it’s about keeping a network running smoothly. That’s why TTL exists!
TTL, or time-to-live, is a mechanism to define the period of time for data to keep living, meaning being valid, stored, or to keep traveling on computers or networks. Once the TTL value defined by the administrators to those data expires, they get discarded.
