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.

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 3600s. -+ -+.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. -+ -+.SH EXAMPLES -+# tc qdisc delete root dev eth0 -+.br -+# tc qdisc add root dev eth0 cake bandwidth 9500Kbit pppoe-ptm ether-vlan -+.br -+# tc -s qdisc show dev eth0 -+.br -+qdisc cake 8007: root refcnt 6 bandwidth 9500Kbit diffserv3 triple-isolate rtt 100.0ms ptm overhead 34 via-ethernet total_overhead 34 hard_header_len 14 -+ Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) -+ backlog 0b 0p requeues 0 -+ memory used: 0b of 4Mb -+ capacity estimate: 9500Kbit -+.br -+ Bulk Best Effort Voice -+.br -+ thresh 593744bit 9500Kbit 2375Kbit -+.br -+ target 30.6ms 5.0ms 7.6ms -+.br -+ interval 125.6ms 100.0ms 102.6ms -+.br -+ pk_delay 0us 0us 0us -+.br -+ av_delay 0us 0us 0us -+.br -+ sp_delay 0us 0us 0us -+.br -+ pkts 0 0 0 -+.br -+ bytes 0 0 0 -+.br -+ way_inds 0 0 0 -+.br -+ way_miss 0 0 0 -+.br -+ way_cols 0 0 0 -+.br -+ drops 0 0 0 -+.br -+ marks 0 0 0 -+.br -+ ack_drop 0 0 0 -+.br -+ sp_flows 0 0 0 -+.br -+ bk_flows 0 0 0 -+.br -+ un_flows 0 0 0 -+.br -+ max_len 0 0 0 -+.br -+ -+After some use: -+.br -+# tc -s qdisc show dev eth0 -+ -+qdisc cake 8007: root refcnt 6 bandwidth 9500Kbit diffserv3 triple-isolate rtt 100.0ms ptm overhead 34 via-ethernet total_overhead 34 hard_header_len 14 -+ Sent 110769306 bytes 313857 pkt (dropped 18, overlimits 741791 requeues 0) -+ backlog 0b 0p requeues 0 -+ memory used: 110488b of 4Mb -+ capacity estimate: 9500Kbit -+.br -+ Bulk Best Effort Voice -+.br -+ thresh 593744bit 9500Kbit 2375Kbit -+.br -+ target 30.6ms 5.0ms 7.6ms -+.br -+ interval 125.6ms 100.0ms 102.6ms -+.br -+ pk_delay 16.0ms 545us 15us -+.br -+ av_delay 2.4ms 161us 3us -+.br -+ sp_delay 59us 1us 1us -+.br -+ pkts 32866 195815 85194 -+.br -+ bytes 8132614 69517496 33122156 -+.br -+ way_inds 0 29208 0 -+.br -+ way_miss 7 173 17 -+.br -+ way_cols 0 0 0 -+.br -+ drops 10 7 1 -+.br -+ marks 217 692 300 -+.br -+ ack_drop 0 0 0 -+.br -+ sp_flows 0 0 0 -+.br -+ bk_flows 0 0 1 -+.br -+ un_flows 0 0 0 -+.br -+ max_len 3028 3012 3028 -+.br -+ -+.SH SEE ALSO -+.BR tc (8), -+.BR tc-codel (8), -+.BR tc-fq_codel (8), -+.BR tc-red (8) -+ -+.SH AUTHORS -+Cake's principal author is Jonathan Morton, with contributions from -+Tony Ambardar, Kevin Darbyshire-Bryant, Toke Høiland-Jørgensen, -+Sebastian Moeller, Ryan Mounce, Dean Scarff, Nils Andreas Svee, and Dave Täht. -+ -+This manual page was written by Loganaden Velvindron.
