Continuous, Real-time Traffic Monitoring and Discovery
Before traffic management policies can be applied, the network administrator must first understand how the network is being used. QoSWorks provides real-time monitoring of over 1400 applications, creating a window into all of the voice, video and data traffic traversing the network. User-friendly charts and reports make it easy to see how much bandwidth each user and application is consuming. This gives administrators clear direction on how to initially set and later adjust policies to best protect application performance QosWorks also discovers and statefully classifies traffic at multiple layers within the OSI 7-layer model. For example in an H.323 call, the control part of the VoIP (RTCP) traffic is classified separately from the media portion (RTP) so that different policies can be applied to the two different streams. Similar procedures can also be applied to SIP calls. This comprehensive traffic monitoring system further allows the IT manager to:- Detect and can gain control over unforeseen applications
- Introduce new applications without degrading performance of existing applications
- Identify and contain harmful applications
- Resolve potential traffic congestion, before it happens.
- Monitor network traffic patterns to enable intelligent policy decisions
- Avoid DoS attacks
A Scalable, Policy-based Solution
Once traffic patterns are understood, the IT manager can easily distribute policies across large and distributed network topologies. Policy templates can be created to meet the needs of different locations (e.g., remote office vs. branch office) and or service profiles. The same template can then be added to new locations or globally updated as new applications (e.g., VoIP) are introduced. In addition, policies can change on the fly. For example, if a user needs more bandwidth to support a conference call between 4PM and 5 PM on Tuesday, the network manager can set the policy ahead of time. It will then be automatically applied at the correct time. It is important to note that the right techniques must be applied in the right combination for each application. QoSWorks combines all of the traffic management techniques described below under a seamless architecture that automatically chooses the best techniques to optimise performance for a particular traffic type.Other Products in this category:
