Abstract: A method for communicating a data packet, the method includes receiving a data packet that supports a packet wash operation. The method determines whether the data packet can be forwarded along a network path towards a destination node without any modification. If the data packet cannot be forwarded along the network path towards the destination node without modification, the method determines whether conditions are met for performing the packet wash operation on the data packet. If the conditions are met, the packet wash operation is performed to generate a washed data packet. The packet wash operation generates the washed data packet by modifying a size of a payload of the data packet based on a packet wash specification that associates attributes to a plurality of data payload portions of the payload of the data packet. The washed data packet is forwarded along the network path towards the destination node.

Abstract: A mechanism operating in a border router is disclosed. The mechanism includes receiving an upstream packet over a limited domain network (LDN). The upstream packet comprises a source address including a LDN suffix. The source address is translated into Internet Protocol version six (IPv6) format by applying a function to translate the LDN suffix into an IPv6 suffix. The upstream packet is forwarded over an IPv6 network based on the source address in IPv6 format.

Abstract: The present technology discloses data communication in a network. A node in the network receives an internet protocol (IP) data packet. The IP data packet has a header and a payload. The node performs actions on the IP data packet based on specifications in the header of the IP data packet. The node then forwards the IP data packet based on the specifications in the header of the IP data packet to a next hop node in the network.

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.
