Abstract: Bandwidth is allocated by leveraging a bursty characteristic of data transmission signals to efficiently utilize network resources. Network performance is observed over a time period to identify patterns of data transmission rates as different signals are processed. To compensate for the fact that different jobs/tasks peak at different times, the total bandwidth limit may be increased by a scaling factor. The scaling factor is calculated using information obtained by observing network performance during the time period. The scaling factor is used to increase the total bandwidth available for all jobs/tasks executing during the time period without exceeding any bandwidth limits. The data transmission rate of each job/task may then be adjusted to utilize the newly available bandwidth.
