The following figure shows the WAN bandwidth allocation model for the WAN-edge egress queuing policy with the default Queuing profile applied. An example of such changes is shown below for two applications. Cisco Wireless Controller 4. February 6, at May 13, at 6: You are commenting using your Twitter account. The protocol pack revision running on the actual router to which policy is deployed may not necessarily match with the version used by EasyQoS.

For example, the new BWR percentage for the Multimedia Streaming traffic class can be calculated as follows:. Each of these queues can use more than its percentage allocation, if more bandwidth is available—meaning if the one or more of the prtocol queues is not using its full allocation of remaining bandwidth percentage. This can be done through the following formula. Hi, This featured added in 7.

The service-policy definition references an existing policy-map definition. The previous class-map and policy-map definitions will not be deleted by EasyQoS. Hi Rasika, please help me to understand.
Once again reload the router. The protocol pack contains the signatures that match the web applications that we can shape. The Voice queue supports traffic with an EF per hop behavior.
For the ISR G2 and Series platforms, the default WRED thresholds for the Default queue are considered cisfo be too aggressive—meaning the minimum drop threshold is set lower than desired. Protocol packs are released with specific NBAR engine versions. This feature is only for customers with advanced knowledge of QoS.
Philip Straatsma Post author July 27, at WAN links that are not connected to service provider managed-service offerings requiring the support of sub-line rate speeds and the re-marking of traffic to meet the traffic-classes provided by the service provider.
The Realtime-Interactive traffic class supports traffic with a CS4 per hop behavior. Read the article https: Under each of these attribute-map definitions, EasyQoS sets the business-relevance attribute.
This is due to better knowledge of how the application is utilized on customer networks or due to changes in how applications are actually cieco on customer networks.

The network operator can use this flexibility in order to assign different bandwidth allocations for uplink ports vs. This includes included bi-directionality and consumers source IP addresses and ports as well as producers destination IP addresses and ports. Network operators have the ability to add Custom applications within the EasyQoS graphical user interface and nbag include these Custom applications within policies pushed by APIC-EM to router and switch platforms.
Therefore, only the top 32 applications from the NBAR2 taxonomy or URL-based Custom applications per traffic-class are mapped to each non-custom class-map entry.

An example of the application of the egress queuing policy is as follows: ISR G2 and Series platforms only. An example of the same application—but with a consumer—is shown below.
In the configuration example above, the traffic-class attribute of the cisco-collab-audio application has been changed from the default value of voip-telephony to a new value of multimedia-conferencing. Network operators have the ability to modify the business-relevance of applications within the EasyQoS graphical user interface and include these changes within policies pushed by APIC-EM to router and switch platforms.
Ethernet and ATM SPAs perform Layer 2 and Layer 3 packet classification, and they also decide on the internal priority of the packet—high priority or low priority.
Because queuing is done in software on ISR and ASR router platforms, the WAN-edge egress queuing policy implements a 12 cosco model—meaning a queue for each of the traffic-classes within the RFC based class QoS model shown in Figure 5 cico in this document. High-priority packets are sent on separate channels to the embedded services processor ESP than low-priority packets. The bandwidth allocations for the 12 traffic-classes for this example Portocol Profile for 1 Gbps interfaces are shown in column 3 of the following table.
