Network Diagnose & Troubleshoot

Dual Algorithm
- Reliable (unicast updates every 60sec)
- Unreliable (unicast updates every 5sec)

K values for Metric Calculations:
K1 = 1 == Bandwidth in kbits
K2 = 0 == Bandwidth in kbits
K3 = 1 == Delay in microseconds
K4 = 0 == Load ===>more load more traffic ===> lower is preffered
K5 = 0 == Reliabilty ===>deals with no. of errors ==> less errors more reliabilty

MTU is a tie-breaker but does not take part in Metric Calculations


Successor Node:
Neighbor connected to Subject Node having lowest neighbor-path metric.

Feasible Node:(Node having the met feasible condition)
In case of multiple paths towards the destination route, the neighboring node having a path-metric lower than the lowest metric in towards destination is considered as feasible node
