Abstract
A Self-Describing Packet block (SDPB) is defined that allows concurrent processing of various fixed headers in a packet block defined to take advantage of multiple cores in a networking node forwarding path architecture. SPDB allows concurrent processing of various pieces of header data, metadata, and conditional commands carried in the same data packet by checking a serialization flag set upon creation of the data packet, without needing to serialize the processing or even parsing of the packet. When one or h more commands in one or more sub-blocks may be processed concurrently, the one or more commands are distributed to multiple processing resources for processing the commands in parallel. This architecture allows multiple unique functionalities each with their own separate outcome (execution of commands, doing service chaining, performing telemetry, allows virtualization and path steering) to be performed concurrently with simplified packet architecture without incurring additional encapsulation overhead.
