NTA Features Include:

• Identifies network-wide top talkers and top applications so that you always know who and what are using the most bandwidth
• Provides QoS performance views to determine if the network is best configured to meet company goals and to easily view network traffic segmented by Class of Service methods, such as Type of Service or DSCP
• Supports NetFlow v5, NetFlow v9, J-Flow, and sFlow v5 data
• Performs port application grouping to facilitate investigation of application-specific performance issues
• Enables creation of personalized views by filtering NetFlow information by specific parameters, such as domain traffic generated during standard office hours (8am to 5pm) from a specific IP address
• Offers fully integrated NetFlow resources within Orion views

Orion NetFlow Traffic Analyzer provides a new level of visibility into network traffic behavior and trends. By leveraging Cisco’s NetFlow protocol to extract data from routers, NetFlow Traffic Analyzer provides an in-depth view into which users and applications are consuming the most bandwidth.

NetFlow Traffic Analyzer converts that data into charts and tables providing network engineers with a easy way to identify and isolate the cause and source of network problems, as well as provide historical performance information to help plan for future growth. Pie charts show the distribution of bandwidth across different types of traffic (e.g., HTTP, FTP, VoIP) and across different users. Line charts show the usage patterns over time. NetFlow Traffic Analyzer can also identify the source of external traffic inbound to the corporate network.

NetFlow Traffic Analyzer solves every-day networking concerns for networking engineers such as:

• What applications are consuming network bandwidth?
• Which users are generating the most traffic?
• What IP addresses are my top talkers?
• Should I upgrade my WAN bandwidth? Why?
• What is the historical trend of bandwidth of my WAN
  and LAN links?
• When my network is running hot, what’s going on?

New to version 3.6:

• Improved Performance and Usability
• Enable Top Talker Optimization to boost collection performance up to 10x and reduce system resource and disk usage
• View CBQoS data in interface detail views without having to enable NetFlow on source interfaces
• Find settings more easily with new NTA admin area reorganization
• Customizable Rate-based Charts
• Choose between rate (Kbps), percent interface speed, percent of total traffic, or total transferred per time unit (same as today)
• Choose between stack charts or line charts
• Advanced Application Mapping
• Use IP address(es) or ranges in combination with port(s) to define an application
• Parse web traffic into discrete applications (e.g. YouTube versus Salesforce.com)
• New and Improved IP Address Groups
• Create IP address groups that include multiple ranges and IP addresses
• Analyze how network traffic is behaving geographically
