- Transforming Network Capacity Planning From an Art to a Science
- As recently as 2000, Cisco relied almost exclusively on Simple Network Management Protocol SNMP to monitor overall WAN bandwidth utilization. Measuring overall traffic, however, does little to characterize network traffic, which is essential to deciding if additional capacity is warranted. Without knowing what types of traffic are using the network,...

- Network Capacity Planning Saves Money, Improves Performance Across Cisco Systems
- Starting in 2000, bandwidth requirements at Cisco Systems began to double every 12 to 18 months, degrading performance on established circuits. Driving bandwidth consumption were voice over IP and video on demand, which share the network with more conventional business applications. Cisco developed a structured process for planning bandwidth requirements...

- Perform effective VoIP network capacity planning
- Network engineers, analysts and administrators characterize network capacity as the amount of traffic the network is designed to handle. When discussing voice over Internet Protocol VoIP, network capacity becomes more a measure of how many simultaneous calls the network can process. This concept of "peak load", the maximum assumed volume...

- On the Capacity of Mobile Ad Hoc Networks With Delay Constraints
- Previous work on ad hoc network capacity has focused primarily on source-destination throughput requirements for different models and transmission scenarios, with an emphasis on delay tolerant applications. In such problems, network capacity enhancement is achieved as a tradeoff with transmission delay. In this paper, the capacity of ad hoc networks...
