| Model | Core Idea | How Alejandra’s Model Extends It | |-------|-----------|---------------------------------| | | Simple hop‑count; no timing. | Adds stochastic hop‑delay and renewal events , yielding a time‑domain survival distribution. | | Kleinrock’s Queue‑TTL (1975) | TTL decrements after each service completion in an M/M/1 queue. | Generalises to arbitrary service‑time distributions (G/G/1) and multiple hops . | | TTL‑based epidemic models (e.g., Daley–Kendall, 1965) | TTL as “time‑to‑forget” in rumor spread. | Introduces node‑specific processing rates and heterogeneous TTL decrements . | | TTL‑aware caching (e.g., LRU‑TTL) | TTL defines cache eviction. | Provides a theoretical TTL‑survival curve that can be plugged into cache‑hit‑rate formulas. | The name appears in related academic and social
The generator (Q) of the process is block‑triangular; for a pure‑decrement case (no renewal) it reduces to: | | Kleinrock’s Queue‑TTL (1975) | TTL decrements

In the case ((\mu_i=\mu,;\Delta_i=1)), this simplifies to a negative‑binomial‑type survival function:
