ABSTRACT:
A system for scheduling data for transmission in a communication network includes a credit distributor and a transmit selector. The communication network includes a plurality of children. The transmit selector is communicatively coupled to the credit distributor. The credit distributor operates to grant credits to at least one of eligible children and children having a negative credit count. Each credit is redeemable for data transmission. The credit distributor further operates to affect fairness between children with ratios of granted credits, maintain a credit balance representing a total amount of undistributed credits available, and deduct the granted credits from the credit balance. The transmit selector operates to select at least one eligible and enabled child for dequeuing, bias selection of the eligible and enabled child to an eligible and enabled child with positive credits, and add credits to the credit balance corresponding to an amount of data selected for dequeuing.
