- * Network Service Type for option SO_NET_SERVICE_TYPE
- *
- * The vast majority of sockets should use Best Effort that is the default
- * Network Service Type. Other Network Service Types have to be used only if
- * the traffic actually matches the description of the Network Service Type.
- *
- * Network Service Types do not represent priorities but rather describe
- * different categories of delay, jitter and loss parameters.
- * Those parameters may influence protocols from layer 4 protocols like TCP
- * to layer 2 protocols like Wi-Fi. The Network Service Type can determine
- * how the traffic is queued and scheduled by the host networking stack and
- * by other entities on the network like switches and routers. For example
- * for Wi-Fi, the Network Service Type can select the marking of the
- * layer 2 packet with the appropriate WMM Access Category.
- *
- * There is no point in attempting to game the system and use
- * a Network Service Type that does not correspond to the actual
- * traffic characteristic but one that seems to have a higher precedence.
- * The reason is that for service classes that have lower tolerance
- * for delay and jitter, the queues size is lower than for service
- * classes that are more tolerant to delay and jitter.
- *
- * For example using a voice service type for bulk data transfer will lead
- * to disastrous results as soon as congestion happens because the voice
- * queue overflows and packets get dropped. This is not only bad for the bulk
- * data transfer but it is also bad for VoIP apps that legitimately are using
- * the voice service type.
- *
- * The characteristics of the Network Service Types are based on the service
- * classes defined in RFC 4594 "Configuration Guidelines for DiffServ Service
- * Classes"
- *
- * When system detects the outgoing interface belongs to a DiffServ domain
- * that follows the recommendation of the IETF draft "Guidelines for DiffServ to
- * IEEE 802.11 Mapping", the packet will marked at layer 3 with a DSCP value
- * that corresponds to Network Service Type.
- *
- * NET_SERVICE_TYPE_BE
- * "Best Effort", unclassified/standard. This is the default service
- * class and cover the majority of the traffic.
- *
- * NET_SERVICE_TYPE_BK
- * "Background", high delay tolerant, loss tolerant. elastic flow,
- * variable size & long-lived. E.g: non-interactive network bulk transfer
- * like synching or backup.
- *
- * NET_SERVICE_TYPE_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).
- *
- * NET_SERVICE_TYPE_OAM
- * "Operations, Administration, and Management", medium delay tolerant,
- * low-medium loss tolerant, elastic & inelastic flows, variable size.
- * E.g. VPN tunnels.
- *
- * NET_SERVICE_TYPE_AV
- * "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium
- * loss tolerant, elastic flow, constant packet interval, variable rate
- * and size. E.g. video and audio playback with buffering.
- *
- * NET_SERVICE_TYPE_RV
- * "Responsive Multimedia Audio/Video", low delay tolerant, low-medium
- * loss tolerant, elastic flow, variable packet interval, rate and size.
- * E.g. screen sharing.
- *
- * NET_SERVICE_TYPE_VI
- * "Interactive Video", low delay tolerant, low-medium loss tolerant,
- * elastic flow, constant packet interval, variable rate & size. E.g.
- * video telephony.
- *
- * NET_SERVICE_TYPE_SIG
- * "Signaling", low delay tolerant, low loss tolerant, inelastic flow,
- * jitter tolerant, rate is bursty but short, variable size. E.g. SIP.
- *
- * NET_SERVICE_TYPE_VO
- * "Interactive Voice", very low delay tolerant, very low loss tolerant,
- * inelastic flow, constant packet rate, somewhat fixed size.
- * E.g. VoIP.
