Will VoLTE (Voice over LTE) Degrade Your Network Performance?
According to PCMagazine, "VoLTE is the future, and most global carriers will be going there over the next two years...
It will be a carrier requirement.."
As VoLTE and other real-time mobile services are broadly adopted, the average packet size will drop and packet rates will
increase in mobile networks. Higher packet rates require more processing capability from core network equipment. This
additional processing load could fundamentally shift the planning assumptions that many operators have used for forecasting
network capacity requirements. Unplanned capacity expansion can strain operator profitability.
Stoke recently completed two mobile traffic analyses that examine the trend towards smaller packet sizes, its drivers, and
the importance of packets rates in capacity planning and vendor evaluation.
Why do Small Packet Sizes matter in your network planning?
As average packet sizes fall and packet arrival rates increase, throughput can decrease dramatically on network elements.
When VoLTE and other real-time, small packet applications are added to your network, throughput on many network elements
can decline as much as 50%. Augmenting capacity by adding additional network equipment escalates capital and operating costs.
Operators need to know the processing and throughput capabilities for a range of packet sizes in the network.
Do you know your network equipment's packet processing limits?
Network planning based on throughput alone is not enough to ward off unplanned expansion. Adding Packets per Second (PPS) to
LTE network equipment evaluation can enable operators to define the equipment's packet processing and forwarding limits for
encrypted packets. By identifying the maximum PPS, operators can better scale network equipment and prepare for unpredictable
