Non-Invasive Network Management (2001)
By Bruce F. Bahlmann, Alopa Networks
Broadband operators have extremely limited visibility into the health of Hybrid-Fiber Coax (HFC). Their limited visibility is due to several factors including the complexity of their transport medium, type of network, and sophistication of their back office. To navigate these factors, a more non-invasive approach to managing HFC is needed. This paper will present such an approach that is completely scalable, offers sophisticated location logic that enable one to quickly locate the most common types of HFC outages, utilizes a mere fraction of the bandwidth required by other network management efforts, and will fully integrate into existing top-level network management systems without additional stand alone status monitors.
