Today our DOCSIS networks are inherently insecure and many are unaware of this.  What do I mean by insecure?  No, not crying and sniffling in a corner.  They are open to theft of service, illegal intercept of the data transmitted, illegal wiretapping of phone calls, etc.  Even with Baseline Privacy Interface Specification (BPI+) DOCSIS is quite hackable as evidenced on a number of well-known hacking sites.

With recent news headlines reading “A U.S. House Intelligence Committee is launching an investigation against Chinese telecommunication equipment suppliers Huawei and ZTE to find whether the companies pose a security threat to the country“, it is becoming more imperative that we as an industry take a pro-active approach to securing our DOCSIS networks. How does this tie into Capacity Planning? If you build it - They will come to fill it.  Theft of service directly impacts capacity planning.


The goal of capacity planning is to identify the amount of resources required to meet service demands now and in the future. It is a proactive discipline with far-reaching impact, supporting:

  • Business alignment, helping to show the cost and business need for infrastructure upgrades;
  • Consolidation strategies, ensuring that consolidated system configurations will meet service levels,
  • Green initiatives, facilitating the optimization of power requirements;
  • Purchasing decisions, minimizing costs needed to maximize productivity;
  • Application development, predicting the impact on production systems of new or modified applications;
  • Disaster recovery plans, determining the optimal way to handle workloads after a catastrophe;
  • And more...The benefits are wide spread, and the effects are game-changing.  This is critical in keeping paying customers online and therefore satisfied.

Capacity Planning...Who Benefits?


  • Increase revenue through maximum availability, decreased downtime, improved response times, greater productivity, greater responsiveness to market dynamics, greater return on investment
  • Decrease costs  through higher capacity utilization, more efficient processes, just-in-time upgrades, greater cost control


  • Control infrastructure costs and stay within budget
  • Objectively verify the recommendations of your vendors
  • Make smart decisions by realizing cost vs. benefit tradeoffs for various configuration options
  • Negotiate service levels with business units knowing the resources required to meet them
  • Provide input to business plans regarding costs of supporting various services
  • Make informed purchasing choices based on business impact
  • Support business unit objectives with minimum risk[/list]
