++.SH DESCRIPTION
++CAKE (Common Applications Kept Enhanced) is a shaping-capable queue discipline
++which uses both AQM and FQ. It combines COBALT, which is an AQM algorithm
++combining Codel and BLUE, a shaper which operates in deficit mode, and a variant
++of DRR++ for flow isolation. 8-way set-associative hashing is used to virtually
++eliminate hash collisions. Priority queuing is available through a simplified
++diffserv implementation. Overhead compensation for various encapsulation
++schemes is tightly integrated.
++
++All settings are optional; the default settings are chosen to be sensible in
++most common deployments. Most people will only need to set the
++.B bandwidth
++parameter to get useful results, but reading the
++.B Overhead Compensation
++and
++.B Round Trip Time
++sections is strongly encouraged.
++
++.SH SHAPER PARAMETERS
++CAKE uses a deficit-mode shaper, which does not exhibit the initial burst
++typical of token-bucket shapers. It will automatically burst precisely as much
++as required to maintain the configured throughput. As such, it is very
++straightforward to configure.
++.PP
++.B unlimited
++(default)
++.br
++ No limit on the bandwidth.
++.PP
++.B bandwidth
++RATE
++.br
++ Set the shaper bandwidth. See
++.BR tc(8)
++or examples below for details of the RATE value.
++.PP
++.B autorate_ingress
++.br
++ Automatic capacity estimation based on traffic arriving at this qdisc.
++This is most likely to be useful with cellular links, which tend to change
++quality randomly. A
++.B bandwidth
++parameter can be used in conjunction to specify an initial estimate. The shaper
++will periodically be set to a bandwidth slightly below the estimated rate. This
++estimator cannot estimate the bandwidth of links downstream of itself.
++
++.SH OVERHEAD COMPENSATION PARAMETERS
++The size of each packet on the wire may differ from that seen by Linux. The
++following parameters allow CAKE to compensate for this difference by internally
++considering each packet to be bigger than Linux informs it. To assist users who
++are not expert network engineers, keywords have been provided to represent a
++number of common link technologies.
++
++.SS Manual Overhead Specification
++.B overhead
++BYTES
++.br
++ Adds BYTES to the size of each packet. BYTES may be negative; values
++between -64 and 256 (inclusive) are accepted.
++.PP
++.B mpu
++BYTES
++.br
++ Rounds each packet (including overhead) up to a minimum length
++BYTES. BYTES may not be negative; values between 0 and 256 (inclusive)
++are accepted.
++.PP
++.B atm
++.br
++ Compensates for ATM cell framing, which is normally found on ADSL links.
++This is performed after the
++.B overhead
++parameter above. ATM uses fixed 53-byte cells, each of which can carry 48 bytes
++payload.
++.PP
++.B ptm
++.br
++ Compensates for PTM encoding, which is normally found on VDSL2 links and
++uses a 64b/65b encoding scheme. It is even more efficient to simply
++derate the specified shaper bandwidth by a factor of 64/65 or 0.984. See
++ITU G.992.3 Annex N and IEEE 802.3 Section 61.3 for details.
++.PP
++.B noatm
++.br
++ Disables ATM and PTM compensation.
++
++.SS Failsafe Overhead Keywords
++These two keywords are provided for quick-and-dirty setup. Use them if you
++can't be bothered to read the rest of this section.
++.PP
++.B raw
++(default)
++.br
++ Turns off all overhead compensation in CAKE. The packet size reported
++by Linux will be used directly.
++.PP
++ Other overhead keywords may be added after "raw". The effect of this is
++to make the overhead compensation operate relative to the reported packet size,
++not the underlying IP packet size.
++.PP
++.B conservative
++.br
++ Compensates for more overhead than is likely to occur on any
++widely-deployed link technology.
++.br
++ Equivalent to
++.B overhead 48 atm.
++
++.SS ADSL Overhead Keywords
++Most ADSL modems have a way to check which framing scheme is in use. Often this
++is also specified in the settings document provided by the ISP. The keywords in
++this section are intended to correspond with these sources of information. All
++of them implicitly set the
++.B atm
++flag.
++.PP
++.B pppoa-vcmux
++.br
++ Equivalent to
++.B overhead 10 atm
++.PP
++.B pppoa-llc
++.br
++ Equivalent to
++.B overhead 14 atm
++.PP
++.B pppoe-vcmux
++.br
++ Equivalent to
++.B overhead 32 atm
++.PP
++.B pppoe-llcsnap
++.br
++ Equivalent to
++.B overhead 40 atm
++.PP
++.B bridged-vcmux
++.br
++ Equivalent to
++.B overhead 24 atm
++.PP
++.B bridged-llcsnap
++.br
++ Equivalent to
++.B overhead 32 atm
++.PP
++.B ipoa-vcmux
++.br
++ Equivalent to
++.B overhead 8 atm
++.PP
++.B ipoa-llcsnap
++.br
++ Equivalent to
++.B overhead 16 atm
++.PP
++See also the Ethernet Correction Factors section below.
++
++.SS VDSL2 Overhead Keywords
++ATM was dropped from VDSL2 in favour of PTM, which is a much more
++straightforward framing scheme. Some ISPs retained PPPoE for compatibility with
++their existing back-end systems.
++.PP
++.B pppoe-ptm
++.br
++ Equivalent to
++.B overhead 30 ptm
++
++.br
++ PPPoE: 2B PPP + 6B PPPoE +
++.br
++ ETHERNET: 6B dest MAC + 6B src MAC + 2B ethertype + 4B Frame Check Sequence +
++.br
++ PTM: 1B Start of Frame (S) + 1B End of Frame (Ck) + 2B TC-CRC (PTM-FCS)
++.br
++.PP
++.B bridged-ptm
++.br
++ Equivalent to
++.B overhead 22 ptm
++.br
++ ETHERNET: 6B dest MAC + 6B src MAC + 2B ethertype + 4B Frame Check Sequence +
++.br
++ PTM: 1B Start of Frame (S) + 1B End of Frame (Ck) + 2B TC-CRC (PTM-FCS)
++.br
++.PP
++See also the Ethernet Correction Factors section below.
++
++.SS DOCSIS Cable Overhead Keyword
++DOCSIS is the universal standard for providing Internet service over cable-TV
++infrastructure.
++
++In this case, the actual on-wire overhead is less important than the packet size
++the head-end equipment uses for shaping and metering. This is specified to be
++an Ethernet frame including the CRC (aka FCS).
++.PP
++.B docsis
++.br
++ Equivalent to
++.B overhead 18 mpu 64 noatm
++
++.SS Ethernet Overhead Keywords
++.PP
++.B ethernet
++.br
++ Accounts for Ethernet's preamble, inter-frame gap, and Frame Check
++Sequence. Use this keyword when the bottleneck being shaped for is an
++actual Ethernet cable.
++.br
++ Equivalent to
++.B overhead 38 mpu 84 noatm
++.PP
++.B ether-vlan
++.br
++ Adds 4 bytes to the overhead compensation, accounting for an IEEE 802.1Q
++VLAN header appended to the Ethernet frame header. NB: Some ISPs use one or
++even two of these within PPPoE; this keyword may be repeated as necessary to
++express this.
++
++.SH ROUND TRIP TIME PARAMETERS
++Active Queue Management (AQM) consists of embedding congestion signals in the
++packet flow, which receivers use to instruct senders to slow down when the queue
++is persistently occupied. CAKE uses ECN signalling when available, and packet
++drops otherwise, according to a combination of the Codel and BLUE AQM algorithms
++called COBALT.
++
++Very short latencies require a very rapid AQM response to adequately control
++latency. However, such a rapid response tends to impair throughput when the
++actual RTT is relatively long. CAKE allows specifying the RTT it assumes for
++tuning various parameters. Actual RTTs within an order of magnitude of this
++will generally work well for both throughput and latency management.
++
++At the 'lan' setting and below, the time constants are similar in magnitude to
++the jitter in the Linux kernel itself, so congestion might be signalled
++prematurely. The flows will then become sparse and total throughput reduced,
++leaving little or no back-pressure for the fairness logic to work against. Use
++the "metro" setting for local lans unless you have a custom kernel.
++.PP
++.B rtt
++TIME
++.br
++ Manually specify an RTT.
++.PP
++.B datacentre
++.br
++ For extremely high-performance 10GigE+ networks only. Equivalent to
++.B rtt 100us.
++.PP
++.B lan
++.br
++ For pure Ethernet (not Wi-Fi) networks, at home or in the office. Don't
++use this when shaping for an Internet access link. Equivalent to
++.B rtt 1ms.
++.PP
++.B metro
++.br
++ For traffic mostly within a single city. Equivalent to
++.B rtt 10ms.
++.PP
++.B regional
++.br
++ For traffic mostly within a European-sized country. Equivalent to
++.B rtt 30ms.
++.PP
++.B internet
++(default)
++.br
++ This is suitable for most Internet traffic. Equivalent to
++.B rtt 100ms.
++.PP
++.B oceanic
++.br
++ For Internet traffic with generally above-average latency, such as that
++suffered by Australasian residents. Equivalent to
++.B rtt 300ms.
++.PP
++.B satellite
++.br
++ For traffic via geostationary satellites. Equivalent to
++.B rtt 1000ms.
++.PP
++.B interplanetary
++.br
++ So named because Jupiter is about 1 light-hour from Earth. Use this to
++(almost) completely disable AQM actions. Equivalent to
++.B rtt 1000s.
++
++.SH FLOW ISOLATION PARAMETERS
++With flow isolation enabled, CAKE places packets from different flows into
++different queues, each of which carries its own AQM state. Packets from each
++queue are then delivered fairly, according to a DRR++ algorithm which minimises
++latency for "sparse" flows. CAKE uses a set-associative hashing algorithm to
++minimise flow collisions.
++
++These keywords specify whether fairness based on source address, destination
++address, individual flows, or any combination of those is desired.
++.PP
++.B flowblind
++.br
++ Disables flow isolation; all traffic passes through a single queue for
++each tin.
++.PP
++.B srchost
++.br
++ Flows are defined only by source address. Could be useful on the egress
++path of an ISP backhaul.
++.PP
++.B dsthost
++.br
++ Flows are defined only by destination address. Could be useful on the
++ingress path of an ISP backhaul.
++.PP
++.B hosts
++.br
++ Flows are defined by source-destination host pairs. This is host
++isolation, rather than flow isolation.
++.PP
++.B flows
++.br
++ Flows are defined by the entire 5-tuple of source address, destination
++address, transport protocol, source port and destination port. This is the type
++of flow isolation performed by SFQ and fq_codel.
++.PP
++.B dual-srchost
++.br
++ Flows are defined by the 5-tuple, and fairness is applied first over
++source addresses, then over individual flows. Good for use on egress traffic
++from a LAN to the internet, where it'll prevent any one LAN host from
++monopolising the uplink, regardless of the number of flows they use.
++.PP
++.B dual-dsthost
++.br
++ Flows are defined by the 5-tuple, and fairness is applied first over
++destination addresses, then over individual flows. Good for use on ingress
++traffic to a LAN from the internet, where it'll prevent any one LAN host from
++monopolising the downlink, regardless of the number of flows they use.
++.PP
++.B triple-isolate
++(default)
++.br
++ Flows are defined by the 5-tuple, and fairness is applied over source
++*and* destination addresses intelligently (ie. not merely by host-pairs), and
++also over individual flows. Use this if you're not certain whether to use
++dual-srchost or dual-dsthost; it'll do both jobs at once, preventing any one
++host on *either* side of the link from monopolising it with a large number of
++flows.
++.PP
++.B nat
++.br
++ Instructs Cake to perform a NAT lookup before applying flow-isolation
++rules, to determine the true addresses and port numbers of the packet, to
++improve fairness between hosts "inside" the NAT. This has no practical effect
++in "flowblind" or "flows" modes, or if NAT is performed on a different host.
++.PP
++.B nonat
++(default)
++.br
++ Cake will not perform a NAT lookup. Flow isolation will be performed
++using the addresses and port numbers directly visible to the interface Cake is
++attached to.
++
++.SH PRIORITY QUEUE PARAMETERS
++CAKE can divide traffic into "tins" based on the Diffserv field. Each tin has
++its own independent set of flow-isolation queues, and is serviced based on a WRR
++algorithm. To avoid perverse Diffserv marking incentives, tin weights have a
++"priority sharing" value when bandwidth used by that tin is below a threshold,
++and a lower "bandwidth sharing" value when above. Bandwidth is compared against
++the threshold using the same algorithm as the deficit-mode shaper.
++
++Detailed customisation of tin parameters is not provided. The following presets
++perform all necessary tuning, relative to the current shaper bandwidth and RTT
++settings.
++.PP
++.B besteffort
++.br
++ Disables priority queuing by placing all traffic in one tin.
++.PP
++.B precedence
++.br
++ Enables legacy interpretation of TOS "Precedence" field. Use of this
++preset on the modern Internet is firmly discouraged.
++.PP
++.B diffserv-llt
++.br
++ Provides a "Latency-Loss Tradeoff" implementation with five tins:
++.br
++ Low Loss (TOS1, TOS2), 100% threshold, increased Codel target.
++.br
++ Best Effort (general), 100% threshold, normal Codel target & interval.
++.br
++ Low Latency (TOS4, TOS5, VA, EF), 100% threshold, reduced Codel interval.
++.br
++ Bulk (CS1), 6.25% threshold, normal Codel target & interval.
++.br
++ Net Control (CS6, CS7), 6.25% threshold, increased Codel target & interval.
++.PP
++.B diffserv4
++.br
++ Provides a general-purpose Diffserv implementation with four tins:
++.br
++ Bulk (CS1), 6.25% threshold, generally low priority.
++.br
++ Best Effort (general), 100% threshold.
++.br
++ Video (AF4x, AF3x, CS3, AF2x, CS2, TOS4, TOS1), 50% threshold.
++.br
++ Voice (CS7, CS6, EF, VA, CS5, CS4), 25% threshold.
++.PP
++.B diffserv3
++(default)
++.br
++ Provides a simple, general-purpose Diffserv implementation with three tins:
++.br
++ Bulk (CS1), 6.25% threshold, generally low priority.
++.br
++ Best Effort (general), 100% threshold.
++.br
++ Voice (CS7, CS6, EF, VA, TOS4), 25% threshold, reduced Codel interval.
++
++.SH OTHER PARAMETERS
++.B memlimit
++LIMIT
++.br
++ Limit the memory consumed by Cake to LIMIT bytes. Note that this does
++not translate directly to queue size (so do not size this based on bandwidth
++delay product considerations, but rather on worst case acceptable memory
++consumption), as there is some overhead in the data structures containing the
++packets, especially for small packets.
++
++ By default, the limit is calculated based on the bandwidth and RTT
++settings.
++
++.PP
++.B wash
++
++.br
++ Traffic entering your diffserv domain is frequently mis-marked in
++transit from the perspective of your network, and traffic exiting yours may be
++mis-marked from the perspective of the transiting provider.
++
++Apply the wash option to clear all extra diffserv (but not ECN bits), after
++priority queuing has taken place.
++
++If you are shaping inbound, and cannot trust the diffserv markings (as is the
++case for Comcast Cable, among others), it is best to use a single queue
++"besteffort" mode with wash.
