PCC delegation of auto-bandwidth and TE++

A TE++ LSP includes a set of paths that are configured as a specific container statement and individual LSP statements, called sub-LSPs, which all have equal bandwidth. For TE++ LSPs, a normalization process resizes the LSP when either of the following two triggers occurs:

• A periodic timer occurs.
• Bandwidth thresholds are met.

These triggers elicit one of the following responses:

• No change is required.
• LSP splitting - add another LSP and distribute bandwidth across all the LSPs.
• LSP merging - delete an LSP and distribute bandwidth across all the LSPs.

For a TE++ LSP, the NorthStar Controller displays a single LSP with a set of paths. The LSP name is based on the matching prefix name of all members. The correlation between TE LSPs is based on association, and the LSP is deleted when there are no remaining TE LSPs.
