22. How to Avoid Network
Bottlenecks

23. 23
Bottleneck
Bottleneck refers to a phenomenon where
the performance or capacity of an entire
system is limited by a single or small
number of components or resources.
TRAFFIC IN
TRAFFIC OUT

24. 24
Bottleneck
TRAFFIC IN
TRAFFIC OUT
«In to the Perfect Network»
TRAFFIC IN = TRAFFIC OUT

25. 25
Bottleneck
Oversubscription
The worst-case achievable bandwidth over the theoretical bandwidth
Calculation
oversubscription ratio = downlink capacity / uplink capacity,
Example: 48 Gigabit Ethernet ports and 2 10G uplinks lead to 48/20 = 2.4:1
Factors to consider
Traffic flow direction
Network layer
Link failure

Oversubscription
Calculation
oversubscription ratio = downlink capacity / uplink capacity,
Server Room -> Core
oversubscription ratio = 14 x 10Gb / 2 x 10Gb = 7
Switch Access -> Core
oversubscription ratio = 50 x 1Gb / 2 x 10Gb = 2.5
