217 * SO_TC_BK_SYS
218 * "Background System-Initiated", high delay tolerant, high loss
219 * tolerant, elastic flow, variable size & long-lived. E.g: system-
220 * initiated iCloud synching or Time Capsule backup, for which there
221 * is no progress feedbacks.
222 *
223 * SO_TC_BK
224 * "Background", user-initiated, high delay tolerant, high loss tolerant,
225 * elastic flow, variable size. E.g. user-initiated iCloud synching or
226 * Time Capsule backup; or traffics of background applications, for which
227 * there is some progress feedbacks.
228 *
229 * SO_TC_BE
230 * "Best Effort", unclassified/standard. This is the default service
231 * class; pretty much a mix of everything.
232 *
233 * SO_TC_RD
234 * "Responsive Data", a notch higher than "Best Effort", medium delay
235 * tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email,
236 * instant messaging, for which there is a sense of interactivity and
237 * urgency (user waiting for output).
238 *
239 * SO_TC_OAM
240 * "Operations, Administration, and Management", medium delay tolerant,
241 * low-medium loss tolerant, elastic & inelastic flows, variable size.
242 * E.g. VPN tunnels.
243 *
244 * SO_TC_AV
245 * "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium
246 * loss tolerant, elastic flow, constant packet interval, variable rate &
247 * size. E.g. AirPlay playback (both video and audio).
248 *
249 * SO_TC_RV
250 * "Responsive Multimedia Audio/Video", low delay tolerant, low-medium
251 * loss tolerant, elastic flow, variable packet interval, rate and size.
252 * E.g. AirPlay mirroring, screen sharing.
253 *
254 * SO_TC_VI
255 * "Interactive Video", low delay tolerant, low-medium loss tolerant,
256 * elastic flow, constant packet interval, variable rate & size. E.g.
257 * FaceTime video.
258 *
259 * SO_TC_VO
260 * "Interactive Voice", low delay tolerant, low loss tolerant, inelastic
261 * flow, constant packet rate, somewhat fixed size. E.g. VoIP including
262 * FaceTime audio.
263 *
264 * SO_TC_CTL
265 * "Network Control", low delay tolerant, low loss tolerant, inelastic
266 * flow, rate is bursty but short, variable size. E.g. DNS queries;
267 * certain types of locally-originated ICMP, ICMPv6; IGMP/MLD join/leave,
268 * ARP.
