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.

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.
