Method and apparatus to manage digital bus traffic

A method comprising:

• determining a target in-flight packet count for a bus;
• and
• maintaining the target in-flight count by adjusting a number of in-flight packets per stream on the bus.

A method comprising:

• transmitting first packets on a first bus of a plurality of buses;
• and
• maintaining a number of the first packets in-flight on the first bus responsive to a number of the plurality of buses with active streams.

An apparatus comprising:

• a first circuit to transmit first packets on a bus, each packet of the first packets associated with a stream, the first circuit to maintain a number of in flight packets per stream according to a total number of streams on the bus.

An apparatus comprising:

• a bus bridge coupled to a memory by way of a bus, the bus bridge to transmit packets to the memory by way of the bus, each packet of the packets associated with a stream, the bus bridge to maintain a number of in-flight packets per stream according to a total number of streams on the bus.

An apparatus comprising:

• a plurality of buses coupled to a memory;
• and
• a bus bridge coupled to the memory by way of a first one of the plurality of buses, the bus bridge to maintain a number of in-flight packets on the first bus according to a number of the plurality of buses with active streams.
