The rate at which the pitcher throws baseballs is important to the catcher. The catcher can only catch 2 baseballs every ms, if 5 baseballs are thrown to the catcher every ms, the catcher will likely drop baseballs. In our analogy the catcher is the policer controlled by the local Metro Ethernet provider and the pitcher is the shaper at the CE WAN interface, which is either controlled by the end user or Lumen if you purchased managed equipment.
Follow these rules anytime a new circuit is installed or an existing circuit is upgraded:. The last line in bold shows the average rate over the full test, each line in the middle represents the rate at one-second intervals.
The column on the left shows the rate fluctuating around 7—10Mbps. These poor results and fluctuation are due to drops in a policer, this is because TCP will react to the packet loss and slow down as a result. The column on the right shows a more steady rate around 43—44Mbps. This is the result after adding 50Mbps traffic shaping which resolved the policer drops.
Missing or misconfigured traffic shaping can degrade any application voice, video, data, etc. Without traffic shaping. Client connecting to With traffic shaping. Portal help. Control Center.
Globalview DDoS Mitigation. Traffic shaping enables organizations to increase network performance by controlling the amount of data that flows into and out of the network. Traffic is categorized, queued, and directed according to network policies.
Essentially, traffic shaping regulates the network by slowing the transmission of packets classified as less important so that priority applications are delivered without delay.
By managing the bandwidth of the network, organizations can ensure the performance and quality of service of their key applications and business traffic. Where do I need traffic shaping? Does traffic shaping affect any of my other internet activity? Related Resources. Specifically, your external communications strategy and how… Read More. The traffic shaper wizard configures ALTQ and gives firewall administrators the ability to quickly configure QoS for common scenarios, and it allows custom rules for more complex tasks.
ALTQ is inefficient, however, so the maximum potential throughput of a firewall is lowered significantly when it is active. Limiters enforce hard bandwidth limits for a group or on a per-IP address or network basis.
Inside of those bandwidth limits, limiters can also manage traffic priorities. For administrators who are unfamiliar with traffic shaping, it is like a bouncer at an exclusive club.
