cdxQosCtrlUpReservedBW The current total reserved bandwidth in bits per second of
this upstream interface. It is the sum of all MTAs' minimum
guaranteed bandwidth in bits per second currently supported
on this upstream.
cdxQosCtrlUpMaxVirtualBW The maximum virtual bandwidth capacity of this upstream
interface if the admission control is enabled. It is the raw
bandwidth in bits per second times the percentage. If the
admission control is disabled, then this object will contain the
value zero.
cdxQosIfRateLimitAlgm To ensure fairness, the CMTS will throttle the rate for
bandwidth request (upstream)/packet sent (downstream) at
which CMTS issues grants (upstream) or allow packet to be
send (downstream) such that the 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 assigned one token bucket with chosen
algorithm.
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.
wtExPacketDiscard(4): Weighted excess packet discard
algorithm.
shaping(5): token bucket algorithm with shaping.
Upstream supports the following:
• No rate limiting (1)
• Bursty 1 second token bucket algorithm(2)
• Average token usage (CAR-like) algorithm(3)
• Token bucket algorithm with shaping(5)-default for
upstream.
Downstream supports the following:
• No rate limiting (1)
• Bursty 1 second token bucket algorithm(2)-default for
downstream
• Average token usage (CAR-like) algorithm(3)
• Weighted excess packet discard algorithm(4)
