Flow meters are also classified by ISDX, and implemented using service policers (Service Dual Leacky Buckets, SDLB). Leacky buckets are linked together in a leak chain of a leak group. Leak groups a preconfigured to serve buckets within a certain rate interval. Stream gates are time-based policers used by PSFP. Frames are dropped based on the gate state (OPEN/ CLOSE), whose state will be altered based on the Gate Control List (GCL) and current PTP time. Apart from time-based policing, stream gates can alter egress queue selection for the frames that pass through the Gate. This is done through Internal Priority Selector (IPS). Stream gates are mapped from stream filters. Support for tc actions gate and police, have been added to the VCAP IS0 set of supported actions. Examples: // tc filter with gate action $ tc filter add dev eth1 ingress chain 1100000 prio 1 handle 1001 protocol \ 802.1q flower skip_sw vlan_id 100 action gate base-time 0 sched-entry open \ 700000 7 8m sched-entry close 300000 action goto chain 1200000 // tc filter with police action $ tc filter add dev eth1 ingress chain 1100000 prio 1 handle 1002 protocol \ 802.1q flower skip_sw vlan_id 100 action police rate 1gbit burst 8096 \ conform-exceed drop action goto chain 1200000 ================================================================================ Patches ================================================================================ Patch #1: Adds new register needed for PSFP. Patch #2: Adds resource pools to control PSFP needed chip resources. Patch #3: Adds support for SDLB's needed for flow-meters. Patch #4: Adds support for service policers. Patch #5: Adds support for PSFP flow-meters, using service policers. Patch #6: Adds a new function to calculate basetime, required by flow-meters. Patch #7: Adds support for PSFP stream gates. Patch #8: Adds support for PSFP stream filters. Patch #9: Adds a function to initialize flow-meters, stream gates and stream filters. Patch #10: Adds the required flower code to configure PSFP using the tc command.
