+ * SO_TC_RV
+ * "Responsive Multimedia Audio/Video", low delay tolerant, low-medium

+ * E.g. AirPlay mirroring, screen sharing.
+ *
+ * SO_TC_VI
+ * "Interactive Video", low delay tolerant, low-medium loss tolerant,

+ * FaceTime video.
+ *
+ * SO_TC_VO

+ * SO_TC_CTL
+ * "Network Control", low delay tolerant, low loss tolerant, inelastic
