Minimizing Differences In Segment Identifiers For Segment Routing - A simplified explanation of the abstract

This abstract first appeared for US patent application 17967398 titled 'Minimizing Differences In Segment Identifiers For Segment Routing

Simplified Explanation

The abstract describes a method implemented by a node in a segment routing network domain. The method involves receiving a packet from another network domain, obtaining compressed segment identifiers (SIDs), generating a segment routing header (SRH) with various sub-fields, adding the SRH to the packet, and forwarding the packet to another node in the segment routing network domain.

  • The method involves receiving a packet from another network domain.
  • The method includes obtaining compressed segment identifiers (SIDs).
  • The method generates a segment routing header (SRH) with a flag field, a tag field, and a segment list.
  • The SRH is added to the packet.
  • The packet with the SRH is forwarded to another node in the segment routing network domain.

Potential Applications

  • This technology can be applied in segment routing networks to efficiently route packets between different network domains.
  • It can be used in large-scale networks where efficient packet forwarding and routing is crucial.

Problems Solved

  • The method solves the problem of efficiently routing packets through a segment routing network domain.
  • It addresses the challenge of handling segment identifiers (SIDs) and compressing them for more efficient packet forwarding.

Benefits

  • The method allows for more efficient routing of packets in segment routing networks.
  • It reduces the overhead associated with handling segment identifiers (SIDs) by compressing them.
  • The technology improves the overall performance and scalability of segment routing networks.


Original Abstract Submitted

A method implemented by a first node in a segment routing (SR) network domain includes receiving, from a second node of another network domain, a packet that is to pass through the SR network domain in accordance with segment identifiers (SIDs). The method also includes obtaining compressed SIDs corresponding to some of the SIDs. The method includes generating a segment routing header (SRH) having a flag field with a first sub-field, a tag field with a second sub-field and a third sub-field, and a segment list. The method finally includes adding the SRH to the packet, and forwarding the packet with the SRH to a third node in the SR network domain.
