Junos Traffic Vision, a licensed traffic sampling app for MX Series 3D Universal Edge Routers, is available. It provides detailed information on network traffic flows, which is useful for many operations and planning activities. Junos Traffic Vision monitors packets while they are being processed by the router and captures information such as source and destination addresses, packet count information, and packet and byte count information. These details are gathered and exported in a standards-based format to allow Juniper and third-party tools to analyze and present them. This includes usage-based accounting, traffic profiling and traffic engineering. Junos Traffic Vision is a high-performance, scale implementation that can be used inline or on service cards. It can be used alongside lawful intercept filtering or port mirroring without affecting performance.
