339 | * Network Service Type for option SO_NET_SERVICE_TYPE |
340 | * |
341 | * The vast majority of sockets should use Best Effort that is the default |
342 | * Network Service Type. Other Network Service Types have to be used only if |
343 | * the traffic actually matches the description of the Network Service Type. |
344 | * |
345 | * Network Service Types do not represent priorities but rather describe |
346 | * different categories of delay, jitter and loss parameters. |
347 | * Those parameters may influence protocols from layer 4 protocols like TCP |
348 | * to layer 2 protocols like Wi-Fi. The Network Service Type can determine |
349 | * how the traffic is queued and scheduled by the host networking stack and |
350 | * by other entities on the network like switches and routers. For example |
351 | * for Wi-Fi, the Network Service Type can select the marking of the |
352 | * layer 2 packet with the appropriate WMM Access Category. |
353 | * |
354 | * There is no point in attempting to game the system and use |
355 | * a Network Service Type that does not correspond to the actual |
356 | * traffic characteristic but one that seems to have a higher precedence. |
357 | * The reason is that for service classes that have lower tolerance |
358 | * for delay and jitter, the queues size is lower than for service |
359 | * classes that are more tolerant to delay and jitter. |
360 | * |
361 | * For example using a voice service type for bulk data transfer will lead |
362 | * to disastrous results as soon as congestion happens because the voice |
363 | * queue overflows and packets get dropped. This is not only bad for the bulk |
364 | * data transfer but it is also bad for VoIP apps that legitimately are using |
365 | * the voice service type. |
366 | * |
367 | * The characteristics of the Network Service Types are based on the service |
368 | * classes defined in RFC 4594 "Configuration Guidelines for DiffServ Service |
369 | * Classes" |
370 | * |
371 | * When system detects the outgoing interface belongs to a DiffServ domain |
372 | * that follows the recommendation of the IETF draft "Guidelines for DiffServ to |
373 | * IEEE 802.11 Mapping", the packet will marked at layer 3 with a DSCP value |
374 | * that corresponds to Network Service Type. |
375 | * |
376 | * NET_SERVICE_TYPE_BE |
377 | * "Best Effort", unclassified/standard. This is the default service |
378 | * class and cover the majority of the traffic. |
379 | * |
380 | * NET_SERVICE_TYPE_BK |
381 | * "Background", high delay tolerant, loss tolerant. elastic flow, |
382 | * variable size & long-lived. E.g: non-interactive network bulk transfer |
383 | * like synching or backup. |
384 | * |
385 | * NET_SERVICE_TYPE_RD |
386 | * "Responsive Data", a notch higher than "Best Effort", medium delay |
387 | * tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email, |
388 | * instant messaging, for which there is a sense of interactivity and |
389 | * urgency (user waiting for output). |

394 | * E.g. VPN tunnels. |

396 | * NET_SERVICE_TYPE_AV |
