391 | * Network Service Type. Other Network Service Types have to be used only if |
392 | * the traffic actually matches the description of the Network Service Type. |
393 | * |
394 | * Network Service Types do not represent priorities but rather describe |
395 | * different categories of delay, jitter and loss parameters. |
396 | * Those parameters may influence protocols from layer 4 protocols like TCP |
397 | * to layer 2 protocols like Wi-Fi. The Network Service Type can determine |
398 | * how the traffic is queued and scheduled by the host networking stack and |
399 | * by other entities on the network like switches and routers. For example |
400 | * for Wi-Fi, the Network Service Type can select the marking of the |
401 | * layer 2 packet with the appropriate WMM Access Category. |
402 | * |
403 | * There is no point in attempting to game the system and use |
404 | * a Network Service Type that does not correspond to the actual |
405 | * traffic characteristic but one that seems to have a higher precedence. |
406 | * The reason is that for service classes that have lower tolerance |
407 | * for delay and jitter, the queues size is lower than for service |
408 | * classes that are more tolerant to delay and jitter. |
409 | * |
410 | * For example using a voice service type for bulk data transfer will lead |
411 | * to disastrous results as soon as congestion happens because the voice |
412 | * queue overflows and packets get dropped. This is not only bad for the bulk |
413 | * data transfer but it is also bad for VoIP apps that legitimately are using |
414 | * the voice service type. |
415 | * |
416 | * The characteristics of the Network Service Types are based on the service |
417 | * classes defined in RFC 4594 "Configuration Guidelines for DiffServ Service |
418 | * Classes" |
419 | * |
420 | * When system detects the outgoing interface belongs to a DiffServ domain |
421 | * that follows the recommendation of the IETF draft "Guidelines for DiffServ to |
422 | * IEEE 802.11 Mapping", the packet will marked at layer 3 with a DSCP value |
423 | * that corresponds to Network Service Type. |
424 | * |
425 | * NET_SERVICE_TYPE_BE |
426 | * "Best Effort", unclassified/standard. This is the default service |
427 | * class and cover the majority of the traffic. |
428 | * |
429 | * NET_SERVICE_TYPE_BK |
430 | * "Background", high delay tolerant, loss tolerant. elastic flow, |
431 | * variable size & long-lived. E.g: non-interactive network bulk transfer |
432 | * like synching or backup. |
433 | * |
434 | * NET_SERVICE_TYPE_RD |
435 | * "Responsive Data", a notch higher than "Best Effort", medium delay |
436 | * tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email, |
437 | * instant messaging, for which there is a sense of interactivity and |
438 | * urgency (user waiting for output). |
439 | * |
440 | * NET_SERVICE_TYPE_OAM |
441 | * "Operations, Administration, and Management", medium delay tolerant, |
442 | * low-medium loss tolerant, elastic & inelastic flows, variable size. |
443 | * E.g. VPN tunnels. |
444 | * |
445 | * NET_SERVICE_TYPE_AV |
446 | * "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium |
447 | * loss tolerant, elastic flow, constant packet interval, variable rate |
448 | * and size. E.g. video and audio playback with buffering. |
449 | * |
450 | * NET_SERVICE_TYPE_RV |
451 | * "Responsive Multimedia Audio/Video", low delay tolerant, low-medium |
452 | * loss tolerant, elastic flow, variable packet interval, rate and size. |
453 | * E.g. screen sharing. |
454 | * |
455 | * NET_SERVICE_TYPE_VI |
456 | * "Interactive Video", low delay tolerant, low-medium loss tolerant, |
457 | * elastic flow, constant packet interval, variable rate & size. E.g. |
458 | * video telephony. |
459 | * |
460 | * NET_SERVICE_TYPE_SIG |
461 | * "Signaling", low delay tolerant, low loss tolerant, inelastic flow, |
462 | * jitter tolerant, rate is bursty but short, variable size. E.g. SIP. |
463 | * |
464 | * NET_SERVICE_TYPE_VO |
465 | * "Interactive Voice", very low delay tolerant, very low loss tolerant, |
466 | * inelastic flow, constant packet rate, somewhat fixed size. |
467 | * E.g. VoIP. |
