The main factor contributing to the need for more bandwidth is E-mail. All of us send each other too many file attachments, such as huge spreadsheets, written documents, or PowerPoint presentations. Web browsing ranks second as a bandwidth hog. Pouring asphalt for new streets is just one part of the solution to traffic congestion. Total gridlock may still ensue if you fail to manage the traffic with stoplights, yield signs, timed traffic signals, and other control measures.
Organizational size affects the choice of techniques.
Midsize companies, by a large margin, will use policy-based management, while larger companies favor quality of service. One way around bandwidth bottlenecks is to seek outside help. Outsourcing, in this case, generally means turning to a carrier-provided service for something like bandwidth on demand. When you run out of your own bandwidth, just call your supplier. Companies with more nodes and higher annual revenue are more likely to use these types of services than those with fewer nodes or lower revenue.
