Bandwidth on demand

(also BOND, BOD)

Bandwidth on demand definition

Bandwidth on demand is a networking method that allows users to dynamically allocate network bandwidth. This differs from traditional networking setups, where bandwidth is allocated based on predefined capacities, leaving users with only a fixed amount at their disposal.

Bandwidth on demand advantages

Bandwidth on demand provides several advantages, including improved network efficiency and cost savings. For example, users can request additional bandwidth when video conferencing or transferring large files, but reduce usage when performing routine tasks to let their organization employ the unused bandwidth elsewhere. This is particularly valuable in cloud computing environments, where variable workloads are the norm.

Main types of bandwidth on demand services

  • Instant bandwidth on demand: The user requests additional bandwidth in response to an immediate need, such as an unplanned video conference. In this situation, users are subject to the available network capacity and may have to pay a premium during peak hours.
  • Scheduled bandwidth on demand: The user is allocated additional bandwidth at predetermined times — for example, when they need to perform a monthly backup or when they’re holding a weekly meeting. Because the bandwidth increase is set up in advance and often involves long-term contracts, users pay less and are not subject to the fluctuating state of the network.
  • Hybrid models: In hybrid bandwidth on demand models, users reserve some bandwidth increases at specific periods of time while retaining the ability to purchase additional bandwidth as needed. Typically, this involves a subscription with additional pay-as-you-go provisions.
