IEEE 802.1Qcd-2015 pdf free download – IEEE Standard for Local and metropolitan area networks— Bridges and Bridged Networks— Amendment 28: Per-Stream Filtering and Policing.
5. Conformance
5.4 VLAN Bridge component requirements
5.4.1 VLAN Bridge component options
Insert new subclause 5.4.1.8 as shown, renumbering as necessary:
5.4.1.8 Per-stream filtering and policing (PSFP) requirements
A VLAN Bridge component implementation that conforms to the provisions of this standard for PSFP shall:
a) Support PSFP as specified in 8.6.5.1 and 8.6.6.1.
b) Support the state machines for stream gate control as specified in 8.6.10.
c) Support the management entities for PSFP as specified in 12.31.
5.13 MAC Bridge component requirements
5.13.1 MAC Bridge component options
Insert new subclause 5.13.1.1 as shown, renumbering as necessary:
5.13.1.1 Per-stream filtering and policing (PSFP) requirements
A MAC Bridge component implementation that conforms to the provisions of this standard for PSFP shall:
a) Support PSFP as specified in 8.6.5.1 and 8.6.6.1.
b) Support the state machines for stream gate control as specified in 8.6.10.
c) Support the management entities for PSFP as specified in 12.31.
Insert the following new subclause at the end of Clause 5, renumbering as necessary:
5.27 End-station requirements — PSFP
An end-station implementation that conforms to the provisions of this standard for PSFP shall:
a) Support PSFP as specified in 8.6.5.1 and 8.6.6.1.
b) Support the state machines for stream gate control as specified in 8.6.10.
c) Support the management entities for PSFP as specified in 12.31.
8. Principles of bridge operation
8.6 The Forwarding Process
Replace Figure 8-11 with the following figure. The effect of this replacement is to change “Ingress (8.6.2)” to “Ingress filtering (8.6.2)” and “Egress (8.6.4)” to “Egress filtering (8.6.4)” to match the subclause headings.
8.6.5 Flow classification and metering
Insert new list item e) immediately following list item d), and change the sentence immediately following new item e), renumbering following list items, as shown:
e) connection_identifier
Item c), specifying a VID value, is not applicable to VLAN-unaware MAC Relays. Item e), specifying a connection_identifier, is only applicable to bridges that support PSFP.
Insert new subclause 8.6.5.1, Figure 8-12, and Table 8-5 as shown, renumbering subsequent figures and tables as necessary:
8.6.5.1 Per-stream filtering and policing
A Bridge or an end station may support PSFP capabilities that allow filtering and policing decisions, and subsequent frame queuing decisions (8.6.6.1), to be made on a per-stream basis for received frames.
Support of PSFP requires implementation of the Stream identification function specified in Clause 6 of IEEE Std 802.1CB, as the stream_handle provided by this function is used in the policing and queuing
decisions taken by PSFP.IEEE 802.1Qcd pdf download.
