Abstract
Some embodiments provide a method for a hardware forwarding element. The method receives a packet to add to a buffer. The packet is assigned a packet class. The method determines an amount of buffer space available for the assigned packet class. Different packet classes have different amounts of buffer space available in the buffer. When the available buffer space for the assigned packet class is large enough for the received packet, the method adds the packet to the buffer.
