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.
