Systems and methods for dynamically allocating network bandwidth

An improved system for allocating bandwidth allows a network customer to dynamically modify bandwidth settings for their private networks. Applicable modified bandwidth settings may include port speed, committed access rate, and Ethernet flow. Port speed determines how much total data may pass through a node in a private network at one time, while committed access rate determines how much bandwidth the node will commit to a particular class of service. Ethernet flow governs the bandwidth allowed over a private line between two nodes. A bandwidth modification request is received by an input interface, which provides it to a processing server that schedules the modification request for committal. The processing server also changes customer billing information accordingly. Additionally, the user may specify a future time when the bandwidth modification request should be committed.
