How to Avoid Network Bottlenecks

22

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

Bottleneck

TRAFFIC IN

TRAFFIC OUT

«In to the Perfect Network»

TRAFFIC IN = TRAFFIC OUT

25

BottleneckOversubscription

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
