    Abstract: In one embodiment, a method includes identifying, by a network component, a first segment identifier (SID) within a SID list. The first SID includes a first SID block and a first micro SID (uSID). The method also includes initializing, by the network component, a packing list of a uSID carrier with the first uSID of the first SID and initializing, by the network component, a packing block of the uSID carrier with the first SID block of the first SID. The method further includes initializing, by the network component, a remaining packing capacity of the packing list with a carrier capacity of the first SID and initializing, by the network component, an empty compressed SID list.

    Abstract: The present disclosure relates to methods and systems for inserting micro segments into a data packet. The methods may include the steps of receiving a packet with a destination address corresponding to a Micro Segment Identifier (uSID) carrier having one or more existing micro segments followed by one or more empty micro segment positions, receiving information relating to one or more new micro segments to be inserted into the uSID carrier, the one or more new micro segments associated with a new bit length, calculating a remaining bit length of the uSID carrier, the remaining bit length associated with the one or more empty micro segment positions in the uSID carrier, wherein, if the remaining bit length is greater than or equal to the new bit length, updating the uSID carrier by inserting the new micro segments, and forwarding the packet to destinations associated with the updated uSID carrier.

    Abstract: The present disclosure includes methods, systems, and non-transitory computer-readable media for validating data in a data structure used for forwarding packets by a network device comprising sending a data packet probe identifying a destination and including a segment ID, wherein the segment ID maps to a first interpretation by a receiving router to perform an action on the data packet probe to rewrite a portion of a destination address in a header of the data packet probe, and to redirect the data packet probe to the network device that initiated the data packet probe.

    Abstract: In one embodiment, a method includes receiving a packet comprising a destination address in a destination address field of the packet, where the destination address including at least a first global identifier and a second global identifier, determining that the first global identifier corresponds to the first network apparatus, determining that a local identifier in the destination address is associated with the first global identifier, identifying one or more instructions associated with the local identifier, performing one or more functions instructed by the one or more instructions, updating the destination address in the destination field of the packet to an updated destination address, determining a forwarding rule associated with the packet, and forwarding the packet with the updated destination address based on the forwarding rule.
