NBAR2 Protocol Pack 6.0.0 is the first protocol pack that contains the Enhanced Web Classification feature that supports multi-transaction export of URLs. For more information on this feature, see Classifying Network Traffic Using NBAR.
The NBAR2 Protocol Pack 6.0.0 introduces the support for detecting PCoIP (vm ware-view) granularly, to provide per session and per packet QoS. This feature has been developed in collaboration with Teradici, the developer of the PCoIP protocol. Using this feature, different types of traffic can be assigned to different QoS queues with specific priorities. This ensures that the higher priority traffic gets better treatment, there by improving the quality of experience. For more information on this feature, see the Application Visibility and Control for PCoIP white paper.
Network Based Application Recognition (NBAR) Protocol Pack 6.0.0 is supported on Cisco ASR 1000 Series Aggregation Services Routers.
