Service flow. A Service Flow (SF) is a MAC transport service that provides unidirectional transport of packets on the uplink or on the downlink. A service flow is identified by a 32-bit SFID (Service Flow IDentifier). The service flow defines the QoS parameters for the packets (PDUs) that are exchanged on the connection.

Re: On Demand - An error occurred during video playback

Congestion avoidance mechanisms, such as WRED, can be used to drop packets as the queues fill up in order to throttle back TCP-based applications. This deterministic dropping of traffic for class-based queues can reduce the possibility of congestion for all applications. These settings use DSCP markings to determine the priority of packets to be dropped before the queue becomes full.

Shaping and Policing

Policing involves checking the packet rate for a particular classification of flows to determine if it conforms to specified rate settings. The policer will check to see if there is excess traffic, and if excess traffic exists, it can drop the packets in order to conform to that specified rate.

The policer can also specify thresholds for exceeding as well as violating and can take actions that include marking down DSCP values rather than simply dropping packets. Markdown involves changing the DSCP value in the IP packet based on flow conditions, which changes the priority of the packets as they traverse the network.

Shaping involves delaying packets that exceed a software defined threshold. If more data is trying to be sent than the shaped threshold, packets are held in the buffer until a later time when they can be sent out. This has the effect of smoothing outbursts, but unlike policers, shaping will attempt to not drop packets in the process. Queuing polices can be assigned to the shaped buffer to prioritize applications as they leave the buffer. If there is congestion or a large amount of traffic, however, the buffer may overflow, causing dropped packets.
