Abstract
Packets are colored and stored in a shared packet buffer without assigning fixed page allocations per port. The packet buffer is divided into three areas—an unrestricted area, an enforced area, and a headroom area. Regardless of the fullness level, when a packet is received it will be stored in the packet buffer. If the fullness level is in the unrestricted area, no flow control messages are generated. If the fullness level is in the enforced region, a probabilistic flow control generation process is used determine if a flow control messages will be generated. If the fullness level is in the headroom area, flow control is automatically generated. Quanta timers are used to control regeneration of flow control messages.
