We have Overflow-Count, Overflow-Threshold and Underflow-Count, Underflow-Threshold to expedite the process of PCC adjusting the bandwidth instead of waiting for Adjustment-Interval when an abrupt change in bandwidth usage occurs. Similarly, we have Report-Flow-Threshold value for a PCC to report for PCE adjusting bandwidth model instead of waiting for Report-Interval. Can we know if there is rationale behind having different method for PCC controlling bandwidth adjustment and PCE controlling bandwidth adjustment for this case? Why not have the similar mechanism for it ? [Dhruv]: Are you asking why we don’t have a “Report-Flow-Count” (similar to Underflow and overflow-count)? Hmm, I guess “Report-Flow-Count” can be added, it is a good suggestion. This would indicate how many times consecutively, the percentage or absolute difference between the current bandwidth sample and the current bandwidth reservation should be greater than or equal to the report-flow-threshold value, for all the bandwidth samples collected so far to be reported to the PCE immediately. [Dhruv2]: Report-Flow-Count is added in Bandwidth-Usage-Report-Flow-Threshold sub-TLV and Bandwidth-Usage-Report-Flow-Threshold-Percent sub-TLV Report-Flow-Count: This value is used to decide when the bandwidth usage collected so far should be reported when there is a sudden change in bandwidth usage. This value indicates how many times consecutively, the percentage or absolute difference between the current bandwidth sample and the current bandwidth reservation is greater than or equal to the Report-Flow-Threshold value, all the bandwidth samples collected so far are reported to the PCE immediately. https://tools.ietf.org/html/draft-dhody-pce-stateful-pce-auto-bandwidth-07#section-5.3.4 2. Once auto-bandwidth adjustment is enabled for an LSP, Couldn’t find any way to disable auto adjustment feature for an LSP. It would be good to have a means to disable adjustment without bringing the LSP down. Also, changing auto-bandwidth adjustment mode from PCC to PCE or vice versa without LSP down. [Dhruv]: I think this could be useful, will discuss with my co-authors and add mechanism for this in future revision. [Dhruv2]: I have added support for this �C The TLV is encoded in all PCEP messages for the LSP till the auto bandwidth adjustment feature is enabled, the absence of the TLV indicate the PCEP speaker wish to disable the feature. https://tools.ietf.org/html/draft-dhody-pce-stateful-pce-auto-bandwidth-07#section-5.2 The TLV is encoded in all PCEP messages for the LSP till the bandwidth usage reporting feature is enabled, the absence of the TLV indicate the PCEP speaker wish to disable this feature. https://tools.ietf.org/html/draft-dhody-pce-stateful-pce-auto-bandwidth-07#section-5.3 Thanks for your comments and review!
