Challenges Faced by Enterprise Transport Networks
Enterprise customers are in urgent need of intelligent, simplified, and efficient new transport networks to
facilitate rapid digital transformation.
• Diversified services, complex network
structure, unable to quickly adapt to
new service requirements
• Chimney-style network stacking, high
TCO
• There are many types of devices, and
network expansion and upgrade are
difficult.
• The network scale increases
rapidly, but the manual O&M
efficiency is low and the cost is
high.
• Manual review, planning, and
configuration service
provisioning for 30 days
• Fault locating relies heavily on
manual operations, and
troubleshooting takes several
hours.
• CCTV provides Yan Jun
challenges for traditional SDH
network bandwidth.
• Data center disaster recovery
(DR): 100 Gbit/s bandwidth
• Bandwidth operation, lighting
up Dark fiber
Manual O&M
Rapid growth of bandwidth
requirements
Complex network redundancy SDH Network Evolution
• Traditional SDH 10GE rings
cannot meet new service
requirements, such as 100GE,
FC3200.
• Many SDH devices are close to
the end of life, resulting in high
maintenance costs.

• Platforms and line boards on the legacy network (old OSN
1800 V) and core nodes (9800 XBAR) do not need to be
replaced. Only gray interconnection and extended cross-
connect boards need to be expanded.
• Ethernet services can be accessed through EoO+ at any
node.
• E1 services can be accessed through 2M interface boards.
• Aggregation/core nodes (E6616 and E9624) support OSU
cross-connections.
