Credit-based Flow Control FCVC - Basic Algorithm

Credit-based Flow Control FCVC - Basic Algorithm

• N23 Scheme (most efficient)
  • Each upstream node maintains a “credit” balance for each FCVC. The node will forward data only if this balance is positive
  • Downstream node returns credits to the upstream node by sending a credit cell for the VC after forwarding N2 cells - N2 is a design parameter
