Systems and methods for SRv6 micro segment insertion

A method, comprising:

• 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, shifting right the one or more existing micro segments by a number of bits corresponding to the new bit length of the one or more new micro segments, and updating the uSID carrier by inserting the one or more new micro segments into the uSID carrier;
• and
• forwarding the packet to one or more destinations associated with the updated uSID carrier.

One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:

• 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, shifting right the one or more existing micro segments by a number of bits corresponding to the new bit length of the one or more new micro segments, and updating the uSID carrier by inserting the one or more new micro segments into the uSID carrier;
• and
• forwarding the packet to one or more destinations associated with the updated uSID carrier.
