• MSO are utilizing tools that allow for better:
• Hardware Utilization – Level Load your CMTS
• Manpower Effectiveness – Augment once
• Provide reports/data for more effective planning for the HSD Network –
Know what will happen when
• Automate the Mundane Tasks

Edge-Fiber Node Management Challenges
• Basic Practices
– NCP Creation is Based on Nodal Modem Counts (Auspice)
– Time Consuming, tedious, often obsolete before its implemented
– Fundamental flaw, node and port splits are based on
Modem counts and not actual usage

Edge-Fiber Node Management Challenges
• Problems With Today’s Basic Practices
– NCP Creation is Based on Nodal Modem Counts (Auspice)
– Users/modems do not operate on the basic law of averages but rather at best case resembles a Log Normal Distribution or, most likely behave more in line with a Power Law probability distribution pattern
– Time Consuming, tedious, often obsolete before its implemented
– When splitting nodes there is no way to determine nodal contribution to port utilization
– Prone to human error, large spreadsheets lots of room for mistakes
– Fundamental flaw, node and port splits are based on
Modem counts and not actual usage

Port Utilization vs. Modem Counts
• DS Port # 2 (bar 3) illustrates that DS Port Utilization is not necessarily proportional to Modem Counts.
•
Comparing DS Ports #0 (bar 1) and #1 (bar 2) illustrates that growth and the magnitude of weekly variations in DS Port Utilization are also not necessarily proportional to Modem Counts.
• This data is straight from the NCP and Weekly Capacity Utilization Reports.

Expertise for end-to-end success
• Improve Customer Satisfaction
• Less often augmentations less down time for your customers
• Better balanced CMTS and edge elements results in less over-utilized ports offering better throughput to your customers
• Reduce Engineering/Field Cycles
• Turnaround of NCP Designs in 1-2 days from 3-5 days
• Extending the time between augmentations
• Targeting Hardware Utilization
• More efficiently engineered CMTS and edge systems.
• Develop NCPs that more equally distribute utilization across all ports, lowering the number of underutilized resources/ports
• Supports field standardization
