Bandwidth on demand (BOND) is a data communication method which provides additional capacity to accommodate traffic demands. It is mostly used in wide area networks (WANs) and dial-up lines, and helps in delivering flexible, customized connectivity for meeting the needs of the user's data demands. Most telephone companies as well network providers provide bandwidth on demand as part of their offering. Bandwidth on demand provides flexibility as well as scalability to data centers as well as for multi-cloud deployments. It is mostly used for short-term needs.
Bandwidth on demand is also known as dynamic bandwidth allocation.
Bandwidth on demand can reduce the cost associated with a network. It also helps a network to accommodate additional traffic demands. There is no need to overbuy bandwidth to meet usage spikes. Bandwidth on demand helps many enterprises in addressing network events such as conference calls, video conference calls, live video streaming and other similar data-consuming events. For retailers, it also helps in quickly turning up the capacity to handle seasonal spikes and sales events, especially in e-commerce.
For activating bandwidth on demand, users need to submit the request through a web portal/interface associated with the service provider or submit a service request via phone, email or some other method. Similar to bandwidth on demand, bandwidth on time of day exists, which is simply additional capacity at specific times of the day.
Bandwidth on demand has many advantages. It is economical as well as practical in many ways. Consumers can use a switched line and only pay for services that are needed rather than having an expensive dedicated line, which may go underused in many cases. It also helps in implementing network connections which are more efficient, secure and cost-effective. Bandwidth on demand supports scalability and flexibility needed for cloud applications. The technique also helps in maintaining the quality of service in the network.
