Methods and apparatus for early delivery of data link layer packets

Methods and apparatus for non-sequential packet transfer. Prior art multi-processor devices implement a complete network communications stack at each processor. The disclosed embodiments provide techniques for delivering network layer (L3) and/or transport layer (L4) data payloads in the order of receipt, rather than according to the data link layer (L2) order. The described techniques enable e.g., earlier packet delivery. Such design topologies can operate within a substantially smaller memory footprint compared to prior art solutions. As a related benefit, applications that are unaffected by data link layer corruptions can receive data immediately (rather than waiting for the re-transmission of an unrelated L4 data flow) and thus the overall network latency can be greatly reduced and user experience can be improved.
