- Capacity Allocation in Optical Networks Under Dynamic Lightpath Demands
- Efficient planning of optical networks requires an allocation of network capacity subject to certain economic or capacity constraints so that a forecasted network lightpath demand matrix or other performance objectives can be satisfied. Much research on optical networks has concentrated on static design, which aims to either minimize the maximal...

- How Cisco IT Uses NetFlow to Improve Network Capacity Planning
- Of all the issues faced by enterprise companies in managing their networks, capacity planning is one of the most important. More an art than a science until recently, network capacity planning is all about balancing the need to meet user performance expectations against the realities of capital budgeting. WAN bandwidth...

- Adaptive CSMA for Scalable Network Capacity in High-Density WLANs
- Demand for mobile computing devices is unlikely to ebb any time soon. As individuals and businesses continue to use more throughput-hungry applications, High-Density Wireless Local Area Networks (HD-WLANs) designers will need to devise ways to improve network capacity by maximizing special reuse of channels. Tests by Intel researchers show that...

- 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...

- 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...
