5G Network Challenges : Transport Perspective
6 Arrcus, Inc Confidential - Light Reading Webinar
• 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

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
