network managing software

After marking network managing software, the next step is another classification process based on packet markings. At this point, packets might be discarded by a policer (for example, if they exceed an SLA) or a congestion-avoidance mechanism (for example, early dropping because buffers reached the maximum limit). Packets that are not discarded are subject to congestion management (queuing) to prioritize and protect various traffic types when congestion happens to the transmission link. Finally, these packets are scheduled for transmission on the egress link, where shaping might occur to control bursts and ensure that outgoing traffic conforms to any SLA that is in effect on the ingress of the next hop

Link-specific tools usually are required only at WAN edges and include mechanisms for network managing software compression or fragmentation to reduce delay and jitter
