Enforcing strict shortest path forwarding using strict segment identifiers
First Claim
Patent Images
1. A method comprising:
- receiving an advertisement at a node, whereinthe advertisement comprises a segment identifier (SID);
determining whether the SID is a strict SID, whereinthe strict SID requires that a strict shortest path is used for a segment corresponding to the strict SID; and
in response to determining that the SID is a strict SID, generating information that identifies a portion of a strict shortest path corresponding to the strict SID.

Abstract
Various systems and methods for using strict path forwarding. For example, one method involves receiving an advertisement at a node. The advertisement includes a segment identifier (SID). In response to receiving the advertisement, the node determines whether the SID is a strict SID or not. If the SID is a strict SID, the node generates information, such as forwarding information, that indicates how to forward packets along a strict shortest path corresponding to the strict SID.

11. A system comprising:
-
a first node configured to perform receiving an advertisement, wherein the advertisement comprises a segment identifier (SID); determining whether the SID is a strict SID, wherein the strict SID requires that a strict shortest path is used for a segment corresponding to the strict SID; and in response to determining that the SID is a strict SID, generating information that identifies a portion of a strict shortest path corresponding to the strict SID. - View Dependent Claims (12, 13, 14, 15)
