DIAGNOSTICS AND INSIGHT
NETWORKING
54 restricted by the ability of the network infrastructure to support SDN capabilities ; the software can manage different protocol implementations ( NETCONF or SNMP ) and bridge legacy and software-defined networks . This is essential for making network evolution manageable .
Nowhere is this more apparent than with optical network units ( ONUs ). Introducing a new third party ONU can take 3 to 6 months to get right because each ONU vendor has its own interpretation of OMCI standards and they don ’ t always get along .
In a SDAN , OLT and ONU software can be decoupled and management handled in the cloud . This means you can have multiple versions of OMCI running in parallel . And that means you can have all kinds of ONU talking to a single OLT – the management platform knows which OMCI stack to use . ONU selection becomes risk-free , saving time and money . relevant insights can be derived . In addition , different management applications typically keep data in a variety of highly proprietary and inaccessible database systems , preventing reusability and leading to data consistency issues .
In contrast , SDAN solutions centralise configuration , performance and diagnostic data from all network elements in a common data lake in the cloud . Instant access to all data at any time means much more complex and powerful analysis and diagnoses can
DIAGNOSTICS AND INSIGHT
In traditional networks , data is collected in batches and then transformed and processed multiple times across different applications before any
