Global Internet Traffic and Mobile Share, 2017-2022

Note: Excludes Managed IP Traffic, Source: Cisco VNI, 2019

• Internet traffic: 29% CAGR• Mobility impacts cannot be ignored

Growth in global mobile revenue, ARPU, and capex: 2019–24

Source: Omdia, March 2020

• Mobile capex rising faster than revenue• Global ARPUs on the decline

5G Network Challenges : Transport Perspective


• Meeting ultra-low latency requirements (network + edge strategy)• Extending wireline connectivity to new cells sites (cell site densification)• Achieving RAN capacity requirements• Meeting network synchronization requirements• Maintaining 4G networks while also adding 5G networks • And doing all the above with minimal increase to capex!

Operators Look to Disaggregation at the IP Layer


Critical - won’t deploy 5G transport

without them 21%

Very important -white box

switches and routers will be

used extensively

44%

Marginally important -white box

switches and routers will be used in niche applications

32%

Not important at all - no

need for white box in our network

3%

Importance of White Box Switches/Routers in 5G

N=103Source: Heavy Reading

• The separation of networking equipment into functional components and allowing each component to be individually deployed:• Encompasses separation of software OS

from underlying hardware• Requires open APIs to enable SDN control

• Degrees of disaggregation exist• Not one size fits all in the market

• White Box is a specific subset of disaggregation that requires open spec hardware produced by contract manufacturers• White box has its own benefits and

challenges
