Hi Ben, Jesse, Here is an updated series of patches for adding IPFIX support. Following your comments on my previous series of patches, I made the following changes:
- Renamed the OpenFlow sampling action into "sample". - Extended the OpenFlow action to include the observation domain ID and observation point ID, the sampling probability, and an ID of the set of collectors to send IPFIX packets to. - Added a root "FlowSampleCollectorSet" table into OVSDB to associate a list of IPFIX collector addresses with a unique ID (to be used in sample actions). This table currently only refers to the "IPFIX" table, but could be extended to also refer to the "sFlow" table if anyone requests it, to have both IPFIX and sFlow per-flow statistical sampling. - Added a "sampling" column into the "IPFIX" table, with the same meaning as the "sampling" column in the "sFlow" table: if a Bridge is linked to a row with a non-zero "sampling" value, all packets on all ports of a bridge are sampled with that probability. With those changes, those patches add support for both per-bridge and per-flow statistical sampling to IPFIX collectors, and the possibility to add support for per-flow sampling to sFlow collectors later, as requested by Jesse.
