Accuracy
of state information does matter

Performance
loss due to inaccurate state information can be as

high
as 10%

Initially
exploration: some of the state information is really old
|
|
|
|
(in
excess of 20 seconds) and therefore very inaccurate
|
|
|
– |
In
particular under high traffic load: control messages sometimes get lost
