Basic Calculation of the Telecommunication Network Availability and Reliability

Basic Calculation of the Telecommunication Network Availability and Reliability

Note: this calculator was made in relation to me as a telecommunications engineer and is not related to my formula (Haryadi Index or Harmony in Gradation)

In this calculator there are two calculations, which are: (1) Telecommunication Network Availability, and (2) Internet Network Reliability

1.Telecommunication Network Availability

The calculation is done by referring to the formula: Availability = (1 – (total down time/periode of measurement)) * 100%,
Where: Down Time = Time to repair + Testing time + Waiting, Movement & Coordination time

2.Internet Network Realibility

The calculation is done by referring to the formula: a.OEC (effective operational capacity) = the data transfer in Gbyte/ average capacity in Gbyte = the data transfer / (average capacity in Gbps*period of measurement); b.Handling overhead = H / (1-H) where H = the ratio of the number of transmission units, bits, or characters used to specify handling in the ith exchange unit sampled and the corresponding total number of transmission units, bits, or characters in the ith information exchange unit;
c.Encoding Overhead = EO = total bits for encoding purposes / total bits in a message after encoding; d.Throughput Efficiency = 1 / {(1+the probability that a transmission unit will be retransmitted)*(1+the probability that an information exchange unit will have to be retransmitted)};
f.Transaction Time =([injected data *(1+handling overhead)*(1+Encoding overhead)])/((average transmission speed*Throughput Efficiency)).
