Select Class-Of-Service™
| This module lets you prioritize individual applications and manage service level agreements for each traffic class, enabling you to ensure the most important traffic gets the highest priority settings. |
|
With CoS, the enterprise selects the priority each application receives. However, if this prioritization is improperly set, the network will not recognize the class and will forward the traffic at the lowest level of priority. Select Class-of-Service highlights these incorrectly configured settings or applications not prioritized by displaying an "unknown" category.
 This capability helps you quickly locate the improper setting and improve application performance. In addition, you can see how much bandwidth applications such as voice, video, Web, FTP and streaming are using for each class.
When rolling out an MPLS-based/private IP network, you must be able to prioritize individual applications with distinctive Class-of-Service (CoS) settings. For example, VoIP is extremely delay sensitive, so it receives the highest priority. On the other hand, e-mail or HTTP traffic is less critical, so it receives much lower priority. Select Class-of-Service helps you manage and fine-tune application performance as well as validate SLAs for each traffic class.
With private IP services, the service provider designates an amount of bandwidth or a threshold for each CoS setting. If the network becomes congested, or if utilization of any CoS goes above its threshold, prioritized traffic may be "policed" to best effort. Mission-critical or time-sensitive traffic may go from the highest to the lowest prioritization or even be discarded.
Select Class-of-Service lets you see the traffic in each class – and track utilization of all classes above and below threshold levels. Such timely data helps you fine-tune your CoS settings to assure the most important traffic gets the highest priority. You also can minimize the risk of exceeding thresholds and receive SLA measurements for each class setting.

Visual's technology was instrumental to the success of our multi-million dollar ERP initiative because it gave us the knowledge and confidence that our MPLS network was fully optimized for the roll out.
