34// PriorityQueue (Class ID: #277 / 0x0115)
35// NOTE 1 - In [ITU-T G.984.4], this is called a priority queue-G.
36//
37// This ME specifies the priority queue used by a GEM port network CTP in the upstream direction.
38// The upstream priority queue ME is also related to a T-CONT ME. By default, this relationship is
39// fixed by the ONU hardware architecture, but some ONUs may also permit the relationship to be
40// configured through the OMCI, as indicated by the QoS configuration flexibility attribute of the
41// ONU2G ME.
42//
43// In the downstream direction, priority queues are associated with UNIs. Again, the association is
44// fixed by default, but some ONUs may permit the association to be configured through the OMCI.
45//
46// If an ONU as a whole contains priority queues, it instantiates these queues autonomously.
47// Priority queues may also be localized to pluggable circuit packs, in which case the ONU creates
48// and deletes them in accordance with circuit pack pre-provisioning and the equipped
49// configuration.
50//
51// The OLT can find all the queues by reading the priority queue ME instances. If the OLT tries to
52// retrieve a non-existent priority queue, the ONU denies the get action with an error indication.
53//
54// See also Appendix II.
55//
56// Priority queues can exist in the ONU core and circuit packs serving both UNI and ANI functions.
57// Therefore, they can be indirectly created and destroyed through cardholder provisioning actions.
58//
59// In the upstream direction, the weight attribute permits the configuring of an optional traffic
60// scheduler. Several attributes support back pressure operation, whereby a back-pressure signal is
61// sent backwards and causes the attached terminal to temporarily suspend sending data.
62//
63// In the downstream direction, strict priority discipline among the queues serving a given UNI is
64// the default, with priorities established through the related port attribute. If two or more non-
65// empty queues have the same priority, capacity is allocated among them in proportion to their
66// weights. Note that the details of the downstream model differ from those of the upstream model.
67//
68// The yellow packet drop thresholds specify the drop probability for a packet that has been marked
69// yellow (drop eligible) by a traffic descriptor or by external equipment such as a residential
70// gateway (RG). If the current average queue occupancy is less than the minimum threshold, the
71// yellow packet drop probability is zero. If the current average queue occupancy is greater than
72// or equal to the maximum threshold, the yellow packet drop probability is one. The yellow drop
73// probability increases linearly between 0 and max_p as the current average queue occupancy
74// increases from the minimum to the maximum threshold.
75//
76// The same model can be configured for green packets, those regarded as being within the traffic
77// contract.
78//
79// Drop precedence colour marking indicates the method by which a packet is marked as drop eligible
80// (yellow). For discard eligibility indicator (DEI) and priority code point (PCP) marking, a drop
81// eligible indicator is equivalent to yellow colour; otherwise, the colour is green. For
82// differentiated services code point (DSCP) assured forwarding (AF) marking, the lowest drop
83// precedence is equivalent to green; otherwise, the colour is yellow.
84//
85// Relationships
86// One or more instances of this ME are associated with the ONU-G ME to model upstream priority
87// queues if the traffic management option attribute in the ONU-G ME is 0 or 2.//// One or more instances of this ME are associated with a PPTP UNI ME as downstream priority
88// queues. Downstream priority queues may or may not be provided for a virtual Ethernet interface
89// point (VEIP).
90//
91// Attributes
92// Managed Entity Id
93// This attribute uniquely identifies each instance of this ME. The MSB represents the direction
94// (1: upstream, 0:-downstream). The 15 LSBs represent a queue ID. The queue ID is numbered in
95// ascending order by the ONU itself. It is strongly encouraged that the queue ID be formulated to
96// simplify finding related queues. One way to do this is to number the queues such that the
97// related port attributes are in ascending order (for the downstream and upstream queues
98// separately). The range of downstream queue ids is 0 to 0x7FFF and the range of upstream queue
99// ids is 0x8000 to 0xFFFF. (R) (mandatory) (2-bytes)
100//
101// Queue Configuration Option
102// This attribute identifies the buffer partitioning policy. The value 1 means that several queues
103// share one buffer of maximum queue size, while the value 0 means that each queue has an
104// individual buffer of maximum queue size. (R) (mandatory) (1-byte)
105//
106// Maximum Queue Size
107// This attribute specifies the maximum size of the queue, in bytes, scaled by the priority queue
108// scale factor attribute of the ONU2G. (R) (mandatory) (2 bytes)
109//
110// NOTE 2 - In this and the other similar attributes of the priority queue ME, some legacy
111// implementations may take the queue scale factor from the GEM block length attribute of the ANI-G
112// ME. This option is discouraged in new implementations.
113//
114// Allocated Queue Size
115// This attribute identifies the allocated size of this queue, in bytes, scaled by the priority
116// queue scale factor attribute of the ONU2G. (R, W) (mandatory) (2 bytes)
117//
118// Discard_Block Counter Reset Interval
119// Discard-block counter reset interval: This attribute represents the interval in milliseconds at
120// which the counter resets itself. (R,-W) (optional) (2-bytes)
121//
122// Threshold Value For Discarded Blocks Due To Buffer Overflow
123// This attribute specifies the threshold for the number of bytes (scaled by the priority queue
124// scale factor attribute of the ONU2G) discarded on this queue due to buffer overflow. Its value
125// controls the declaration of the block loss alarm. (R, W) (optional) (2-bytes)
126//
127// Related Port
128// This attribute represents the slot, port/T-CONT and priority information associated with the
129// instance of priority queue ME. This attribute comprises 4-bytes.
130//
131// In the upstream direction, the first 2-bytes are the ME ID of the associated T-CONT, the first
132// byte of which is a slot number, the second byte a T-CONT number. In the downstream direction,
133// the first byte is the slot number and the second byte is the port number of the queue's
134// destination port.
135//
136// The last 2-bytes represent the priority of this queue. The range of priority is 0 to 0x0FFF. The
137// value 0 indicates the highest priority and 0x0FFF indicates the lowest priority. The priority
138// field is meaningful if multiple priority queues are associated with a T-CONT or traffic
139// scheduler whose scheduling discipline is strict priority.
140//
141// (R, W) (mandatory) (4 bytes)
142//
143// NOTE 3 - If flexible port configuration is supported, the related port attribute is meaningful
144// only if the traffic scheduler pointer attribute value is null. Otherwise, the related port
145// attribute is ignored.
146//
147// NOTE 4 - The related port attribute is read-only, unless otherwise specified by the QoS
148// configuration flexibility attribute of the ONU2-G ME. If port flexibility is supported, the
149// second byte, the port or T-CONT number, may be changed. If priority flexibility is supported,
150// the third and fourth bytes may be changed. The OMCI set command must contain 4-bytes to match
151// the attribute size, but the ONU must ignore all bytes that are not specified to be flexible.
152//
153// If flexible configuration is not supported, the ONU should reject an attempt to set the related
154// port with a parameter error result-reason code.
155//
156// Traffic Scheduler Pointer
157// The ONU should reject an attempt to violate these conditions with a parameter error result-
158// reason code.
159//
160// This attribute points to the traffic scheduler ME instance that is associated with this priority
161// queue. This pointer is used when this priority queue is connected with a traffic scheduler. The
162// default value is a null pointer (0). (R, W) (mandatory) (2 bytes)
163//
164// NOTE 5 - When the QoS configuration flexibility attribute of the ONU2-G ME allows flexible
165// assignment of the traffic scheduler, the OLT may configure the traffic scheduler pointer to
166// refer to any traffic scheduler in the same slot.
167//
168// If traffic scheduler flexibility is not permitted by the QoS configuration flexibility
169// attribute, the OLT may use the traffic scheduler pointer attribute only by pointing to another
170// traffic scheduler ME that is associated with the same T-CONT as the priority queue itself.
171//
172// Weight
173// This attribute represents weight for WRR scheduling. At a given priority level, capacity is
174// distributed to non-empty queues in proportion to their weights. In the upstream direction, this
175// weight is meaningful if several priority queues are associated with a traffic scheduler or
176// T-CONT whose policy is WRR. In the downstream direction, this weight is used by a UNI in a WRR
177// fashion. Upon ME instantiation, the ONU sets this attribute to 1. (R,-W) (mandatory) (1-byte)
178//
179// Back Pressure Operation
180// This attribute enables (0) or disables (1) back pressure operation. Its default value is 0.
181// (R,-W) (mandatory) (2-bytes)
182//
183// Back Pressure Time
184// This attribute specifies the duration in microseconds of the backpressure signal. It can be used
185// as a pause time for an Ethernet UNI. Upon ME instantiation, the ONU sets this attribute to 0.
186// (R,-W) (mandatory) (4-bytes)
187//
188// Back Pressure Occur Queue Threshold
189// This attribute identifies the threshold queue occupancy, in bytes, scaled by the priority queue
190// scale factor attribute of the ONU2G, to start sending a back-pressure signal. (R, W) (mandatory)
191// (2-bytes)
192//
193// Back Pressure Clear Queue Threshold
194// This attribute identifies the threshold queue occupancy, in bytes, scaled by the priority queue
195// scale factor attribute of the ONU2G, to stop sending a back-pressure signal. (R, W) (mandatory)
196// (2-bytes)
197//
198// Packet Drop Queue Thresholds
199// This attribute is a composite of four 2-byte values, a minimum and a maximum threshold, measured
200// in bytes, scaled by the priority queue scale factor attribute of the ONU2-G, for green and
201// yellow packets. The first value is the minimum green threshold, the queue occupancy below which
202// all green packets are admitted to the queue. The second value is the maximum green threshold,
203// the queue occupancy at or above which all green packets are discarded. The third value is the
204// minimum yellow threshold, the queue occupancy below which all yellow packets are admitted to the
205// queue. The fourth value is the maximum yellow threshold, the queue occupancy at or above which
206// all yellow packets are discarded. The default is that all thresholds take the value of the
207// maximum queue size. (R,-W) (optional) (8-bytes)
208//
209// Packet Drop Max_P
210// This attribute is a composite of two 1-byte values, the probability of dropping a coloured
211// packet when the queue occupancy lies just below the maximum threshold for packets of that
212// colour. The first value is the green packet max_p, and the second value is the yellow packet
213// max_p. The probability, max_p, is determined by adding one to the unsigned value (0..255) of
214// this attribute and dividing the result by 256. The default for each value is 255. (R,-W)
215// (optional) (2-bytes)
216//
217// Queue Drop W_Q
218// This attribute determines the averaging coefficient, w_q, as described in [b-Floyd]. The
219// averaging coefficient, w_q, is equal to 2Queue_drop_w_q. For example, when queue drop_w_q has
220// the value 9, the averaging coefficient, w_q, is 1/512-= 0.001-9. The default value is 9. (R,-W)
221// (optional) (1-byte)
222//
223// Drop Precedence Colour Marking

225//
226// 7 DSCP AF class [IETF RFC 2597]
227//
228// (R,-W) (optional) (1-byte)
229//
230// This attribute specifies how drop precedence is marked on ingress packets to the priority queue.
231// The default value is 0.
