* "Background System-Initiated", high delay tolerant, high loss

* initiated iCloud synching or Time Capsule backup, for which there
* is no progress feedbacks.
*
* SO_TC_BK
* "Background", user-initiated, high delay tolerant, high loss tolerant,
* elastic flow, variable size. E.g. user-initiated iCloud synching or
* Time Capsule backup; or traffics of background applications, for which
* there is some progress feedbacks.
*
* SO_TC_BE
* "Best Effort", unclassified/standard. This is the default service
* class; pretty much a mix of everything.
*
* SO_TC_RD
* "Responsive Data", a notch higher than "Best Effort", medium delay
* tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email,
* instant messaging, for which there is a sense of interactivity and
* urgency (user waiting for output).
*
* SO_TC_OAM
* "Operations, Administration, and Management", medium delay tolerant,
* low-medium loss tolerant, elastic & inelastic flows, variable size.
* E.g. VPN tunnels.
*
* SO_TC_AV
* "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium
* loss tolerant, elastic flow, constant packet interval, variable rate &
* size. E.g. AirPlay playback (both video and audio).
*
* SO_TC_RV
* "Responsive Multimedia Audio/Video", low delay tolerant, low-medium
* loss tolerant, elastic flow, variable packet interval, rate and size.
* E.g. AirPlay mirroring, screen sharing.
*
* SO_TC_VI
* "Interactive Video", low delay tolerant, low-medium loss tolerant,
* elastic flow, constant packet interval, variable rate & size. E.g.
* FaceTime video.
*
* SO_TC_VO
* "Interactive Voice", low delay tolerant, low loss tolerant, inelastic
* flow, constant packet rate, somewhat fixed size. E.g. VoIP including
* FaceTime audio.
*
* SO_TC_CTL
* "Network Control", low delay tolerant, low loss tolerant, inelastic
* flow, rate is bursty but short, variable size. E.g. DNS queries;
* certain types of locally-originated ICMP, ICMPv6; IGMP/MLD join/leave,
* ARP.
