DESCRIPTION
"To ensure fairness, at the upstream, the HE will throttle
the rate of bandwidth grants, such that the flow never
gets more than its provisioned peak rate in bps.
Similarly at the downstream, HE controls the packets
sent such that flow never gets more than its provisioned
peak rate in bps.
There are two directions for every Service Id (Sid) traffic:
downstream and upstream. Each direction is called a service
flow here and is assigned one token bucket with chosen
algorithm.
The enumerations for the rate limiting algorithm are:
noRateLimit(1): The rate limiting is disabled. No rate
limiting.
oneSecBurst(2): Bursty 1 second token bucket algorithm.
carLike(3) : Average token usage (CAR-like) algorithm
wgtExPacketDiscard(4) : Weighted excess packet discard
algorithm.
shaping(5): token bucket algorithm with shaping
Upstream supports all the above except
wgtExtPacketDiscard(4).
Downstream supports all the above rate-limiting algorithms.
Token bucket algorithm with shaping is the
default algorithm for upstream.
Bursty 1 second token bucket algorithm is the
default algorithm for downstream.
Each algorithm is described as below:
No rate limiting:
The rate limiting process is disabled and no checking
against the maximum bandwidth allowed.
Bursty 1 second token bucket rate limiting algorithm:
In this algorithm, at the start of every 1 second interval,
a service flow's token usage is reset to 0, and every time
the modem for that service flow sends a request (upstream) /
packet (downstream) the upstream/downstream bandwidth
token usage is incremented by the size of the
request/packet sent. As long as the service flow's bandwidth
token usage is less than the maximum bandwidth in bits
per second (peak rate limit) its QoS service class
allows, the request/packets will not be restricted.
Once the service flow has sent more than its peak rate in the
one second interval, it is prevented from sending more
data by rejecting request (upstream) or dropping
packets (downstream). This is expected to slow down
the higher layer sources. The token usage counter gets
reset to 0 after the 1 second interval has elapsed. The
modem for that service flow is free to send more data up to the
peak rate limit in the new 1 second interval that follows.
Average token usage (Cisco CAR like) algorithm:
This algorithm maintains a continuous average of the
burst token usage of a service flow. There is no sudden
refilling of tokens every 1 second interval. Every time a
request/packet is to be handled, the scheduler tries to see
how much time has elapsed since last transmission, and
computes the number of tokens accumulated by this service flow
at its QoS class peak rate. If burst usage of the service flow
is less than tokens accumulated, the burst usage is reset to 0
and request/packet is forwarded. If the service flow has
accumulated fewer tokens than its burst usage, the burst usage
shows an outstanding balance usage after decrementing by the
tokens accumulated. In such cases, the request/packet is still
forwarded, provided the service flow's outstanding usage does
not exceed peak rate limit of its QoS class. If outstanding
burst usage exceeds the peak rate of the class, the service
flow is given some token credit up to a certain maximum credit
limit and the request/packet is forwarded. The request/packet
is dropped when outstanding usage exceeds peak rate and maximum
credit has been used up by this service flow. This algorithm
tracks long term average bandwidth usage of the service flow
and controls this average usage at the peak rate limit.
Weighted excess packet discard algorithm:
This rate limiting algorithm is only available as an option
for downstream rate limiting. The algorithm is to maintain an
weighted exponential moving average of the loss rate of a
service flow over time. The loss rate, expressed in packets,
represents the number of packets that can be sent from this
service flow in a one second interval before a packet will
be dropped. At every one second interval, the loss rate gets
updated using the ratio between the flow peak rate (in bps)
in its QoS profile and the service flow actual usage (in bps).
If the service flow begins to send more than its peak rate
continuously, the number of packets it can send in an one
second interval before experiencing a drop will slowly keep
reducing until SU for that service flow slows down
as indicated by actual usage less or equal to the peak rate.
Token bucket algorithm with shaping:
If there is no QoS class peak rate limit, forward the
request/packet without delay. If there is a QoS peak rate
limit, every time a request/packet is to be handled, the
scheduler determines the number of bandwidth tokens that this
service flow has accumulated over the elapsed time at its
QoS class peak rate and increments the tokens counter of the
service flow accordingly. The scheduler limits the token
count to the maximum transmit burst (token bucket depth).
If token count is greater than the number of tokens required
to handle current request/packet, decrement token count by
size of request/packet and forwards the request/packet
without delay. If token count is less than the size of
request/packet, compute the shaping delay time after
which the deficit number of tokens would be available. If
shaping delay time is less than the maximum shaping delay,
decrement tokens count by size of request/packet and
forward this request/packet with the shaping delay in the
shaping delay queue. When the delay time expires, the
request/packet is forwarded. If shaping delay time is
greater than the maximum shaping delay that the subsequent
shaper can handle, the request/packet is dropped. Users can
use cwdxQosIfRateLimitShpMaxDelay to configure the maximum
shaping delay and cwdxQosIfRateLimitShpGranularity to
configure the shaping granularity."

DESCRIPTION
"Weight for exponential moving average of loss rate,
when using weighted excess packet discard algorithm.
The higher values of the weight make the algorithm
more sensitive to the recent bandwidth usage by the Sid.
The default value is 1. Whenever the rate limiting
algorithm is changed to weighted excess packet discard
algorithm, this value will be reset to the default 1.
If the rate limiting algorithm is not weighted excess
packet discard algorithm, the value will be always the
default value 1. You will not be able to set it to
anything other than 1 when it is not weighted excess
packet discard algorithm."

}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The maximum shaping delay in milliseconds. That is, the maximum
amount of time for which the HE will allow buffering of any
rate exceeded flow. If the max buffering delay is large,
then grants/packets of the flow will be buffered for a
longer period of time even though the flow is rate exceeded.
This means fewer chances of drops for such rate exceeded
flow. However, too large a max shaping delay can result in
quick drainage of packet buffers at the HE, since several
packets will be in the shaping (delay) queue waiting for
their proper transmission time. Another important point to
note is that delaying a flow's packets (especially TCP
flows) for extended periods of time may be counter-
productive, since the higher protocol layers may assume
a packet loss after a certain amount of time.
The maximum shaping delay is only applied to rate limit
algorithm: Token bucket algorithm with shaping. If the rate
limit algorithm is not Token bucket algorithm with shaping,
the value is always na(1) which is not applicable. In this
case, you will be allowed to set the value to na(1) only.
If the token count is less than the size of request/packet, HE
computes the shaping delay time after which the deficit number of
tokens would be available. If the shaping delay time is greater
than the maximum shaping delay, the request/packet will be
dropped.
The enumerations for cwdxQosIfRateLimitShpMaxDelay are:
na(1): maximum shaping delay is not applied to the current
rate limit algorithm
msec128(2): maximum shaping delay is 128 milliseconds
msec256(3): maximum shaping delay is 256 milliseconds
msec512(4): maximum shaping delay is 512 milliseconds
msec1024(5): maximum shaping delay is 1024 milliseconds
At the downstream, cwdxQosIfRateLimitShpMaxDelay
is configurable and the default value is msec128(2).
Whenever the downstream rate limit algorithm is changed
to Token bucket algorithm with shaping from other rate
limit algorithm, the value will be reset to the default
value.
At the upstream, cwdxQosIfRateLimitShpMaxDelay is not
configurable and it is read-only value."

MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The width in milliseconds of each element in shaping
delay queue, that is, the shaping granularity.
The shaping granularity is only applied to rate limit
algorithm: Token bucket algorithm with shaping. It
controls how accurately the algorithm quantizes the shaping
delay for a rate exceeded flow. If granularity is large, several
shaping delay values will all be quantized to the same element
in the queue resulting in less accurate rate shaping for the flows
in bits/sec. On the other hand, choosing too small granularity
causes more memory to be used for the shaper block, and also
can cost a bit more in runtime overhead.
If the rate limit algorithm is not Token bucket algorithm with
shaping, the value is always na(1) which is not applicable.
Setting to any thing other than na(1) will be rejected.
The enumerations for shaping granularity are:
na(1): shaping granularity is not applied to the current
rate limit algorithm
msec1(2): shaping granularity in 1 milliseconds
msec2(3): shaping granularity in 2 milliseconds
msec4(4): shaping granularity in 4 milliseconds
msec8(5): shaping granularity in 8 milliseconds
msec16(6): shaping granularity in 16 milliseconds
At the downstream, this object is configurable and the
default value is msec4(4). Whenever the downstream rate limit
algorithm is changed to Token bucket algorithm with shaping
from other rate limit algorithm, the value will be reset to the
default value. When the algorithm is Token bucket algorithm
with shaping and set to same algorithm again the value will
not be reset to default value.
At the upstream, this object is not configurable and
it is read-only value."

SYNTAX CwdxHeSuChOverEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"An HE operation entry to instruct a Subscriber-unit to move
to a new downstream and/or upstream channel.
There can be more than one entry per Subscriber-unit,
so there is a time stamp for each entry to show the time
when this operation is initiated.
A management station wishing to create an entry should
first generate a pseudo-random serial number to be used
as the index to this sparse table. The station should
then create the associated instance of the row status
object. It must also, either in the same or in successive
PDUs, create the associated instance of the command and
parameter objects. It should also modify the default values
for any of the parameter objects if the defaults are not
appropriate.
Once the appropriate instances of all the command
objects have been created, either by an explicit SNMP
set request or by default, the row status should be set
to active to initiate the operation. Note that this entire
procedure may be initiated via a single set request which
specifies a row status of createAndGo as well as specifies
valid values for the non-defaulted parameter objects.
Once an operation has been activated, it cannot be stopped.
That is, it will run until either the HE has generated
downstream frequency and/or upstream channel override fields
in the RNG-RSP message sent to a Subscriber-unit or time out.
In either case, the operation is completed. During this
time the row cannot be destroyed.
Once the operation is completed, the real result of the
operation to the Subscriber-unit cannot be known from this table.
The result of the Subscriber-unit's downstream frequency and the
upstream channel id can be checked from other MIB tables.
For example, cwdIfHeServiceTable from
CISCO-WIRELESS-DOCS-IF-MIB can be used to check
whether the Subscriber-unit's downstream frequency
and upstream channel id are changed. Please note that even
though HE has generated downstream frequency and/or
upstream channel override fields in the RNG-RSP message sent
to a SUs if the SU cannot lock at the instructed downstream
frequency or no upstream channel id could be used, it may
reconnect back to the original downstream frequency and
upstream channel id.
Once the operation completes, the management station should
retrieve the values of the cwdxHeSuChOverState
objects of interest, and should then delete the entry.
In order to prevent old entries from clogging the table,
entries will be aged out, but an entry will never be deleted
within 15 minutes of completing."

DESCRIPTION
"This object is the bit mask (8 bit wide) for
tos-overwrite feature. The
cwdxQosProfTosOverwriteValue is written where the
mark bits are set to 1.
Tos-overwrite allows the HE to mark egress IP packets
(from the HE) with a specific TOS value. This relieves
the subscriber unit from marking upstream packets with
a specific TOS and is most useful when a subscriber
unit is supplied by a third party vendor who may not
have the option of applying a TOS to an IP packet.
Each packet received from an SU that matches this QoS
profile will be tagged with the TOS-overwrite value
at the cwdxQosProfTosOverwriteMask and sent to the
network."
