Read the equation
Divides retransmitted units by the number of segments. The source must specify whether the numerator counts repeated attempts or distinct segments, since those conventions have different ranges.
Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
Read R_t as the quantity being defined or updated by this relation.
Forms a ratio or division. A zero denominator needs an explicit exclusion or handling rule.
Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.
Assumptions & limits
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.

Layer 4 — Transport Layer (N4)
Flow, reliability, retransmission.
1. Retransmission Rate:
R_t = \frac{N_{\text{reTx}}}{N_{\text{segments}}}
2. Flow Window:
W_t = f(C_3, L_3)
3. Cost:
\text{Cost}_4 = a_4 R_t + b_4 (1/W_t)
