A Map-Driven Change Management Process Enable efficient collaboration between IT divisions Successful network changes require multiple groups to work together. A map-driven approach can facilitate communications and enhance collaboration. Deep Application Flow Analysis NetBrain provides the industry's deepest application flow analysis. Given the source and destination addresses of an application, NetBrain can map out both live and historical paths with all dependencies illustrated on the map. Technologies supported include routing, switching, NAT, ACL, MPLS, PBR, etc. Qmap as a Collaboration Media Automate Network Changes 1. Design During the design phase, proposed changes can be documented inside a Qmap to describe impacted devices, and the scope of changes. 3. Implementation Once approved, the implementation team can leverage a Qmap to automatically deploy the network changes, directly from the map. 2. Review Using the free Qmap Reader, a design reviewer can open a single Qmap file with the proposed changes outlined inside. 4. Operations After changes are implemented, the impact of changes can be instantly analyzed using advanced historical analysis. Map between Two Endpoints NetBrain provides deep visualization into the traffic flow by analyzing traffic forwarding decisions at each hop, covering technologies from Layer-1 through layer-7. Deep Application Flow Analysis Result: Accurate data for each phase of the change process Extend Path Analysis Logic Engineers can modify and enhance NetBrain's built-in path analysis - via a visual programming environment - to cover new network technologies. 15 16

Analyze Application Traffic at the Port Level For modern networks, it's not enough to analyze application traffic at the IP level, because technologies like ACL, QoS, or NAT impact the flow. For example, a server may be accessible via a web browser (port 80/443) but telnet traffic (port 23) to the server might be denied. Analyze Traffic Flow across MPLS Technology Modern service provider networks often include MPLS at their core. Using NetBrain, traffic flow across both single and multiple MPLS domains can be analyzed side-by-side with traditional routing and switching technologies. Engineers no longer need to dive into IP, MAC, and MPLS tables manually. Analyze Access-lists NetBrain can analyze access-lists along the path and provide port-level traffic analysis of access-list traffic filtering. Traffic Path across VRF Lite NetBrain calculates the path across MPLS Lite based on LFIB (Label Forwarding Information Base) and maps between CE and PE devices Deep Application Flow Analysis Traffic Path across MPLS Cloud Enterprise networks often use MPLS clouds (MPLS forwarding provided by the service provider). NetBrain supports end-to-end traffic path discovery across the cloud. Deep Application Flow Analysis Decode NAT Translations NetBrain can decode NAT translations along the path and properly group traffic paths in the forward and return direction. 17 18

Policy-Based Routing and Load Balancing In addition to dynamic routing, some networks may leverage PBR (policy-based routing) to route application traffic based on additional metrics. NetBrain understands PBR logic and can map the path across PBR-enable network hops. Network Automation with Qapp Automation Beyond Scripting Designed to replace in-house scripts, NetBrain's Qapp technology makes it possible to customize the automation of any network analysis task. A Qapp is much easier to write than a script - and far more powerful. No Scripting Required Only select few engineers know how to run a custom script, let alone write one. Writing a Qapp is much easier. Policy-Based Routing (PBR) Deep Application Flow Analysis NetBrain will automatically display traffic forwarding which is impacted by PBR if any configured route-maps are detected. Load Balancing & Address Translation In server load balancing setup, a Virtual IP is provided as the target for inbound traffic. A load balancer will dynamically route traffic to one of the real servers based on pre-defined criteria. NetBrain can decode this logic visually. Visual Programming NetBrain's visual programming environment leverages an intuitive syntax. Anyone comfortable with the command-line interface can write a Qapp in as little as 5 minutes. Run a Qapp Sample Qapp Logic Network Automation with Qapp A Qapp doesn't output data to a batch prompt like most scripts - it outputs data to the map so its easy to interpret and visually accessible. All data is saved to the Qmap automatically. Sample Qapp - Output to the Map 19 20

Customized Map-Driven Automation Designed to combine the flexibility of scripting with the power and usability of an enterprise-grade software solution, a NetBrain Qapp is as easy to run as an app on a smartphone. Writing a Custom Qapp There's no complex syntax or steep learning curve for writing a Qapp. After just 15 minutes, of training engineers are usually ready to write their first Qapp. There are three main steps: Run Qapp from NetBrain UI After writing a custom Qapp, you can quickly add it to the NetBrain user interface - ready for any engineer to run. NetBrain already includes dozens of Qapps 'out of the box'. Select Qapp Step 1: Define Variables of Interest A sample of CLI command data is used to identify variables which indicate fields of interest. For example, an interface diagnosis Qapp may use 'show interface'. Define Qapp Variables Data Collection Over Time Step 2: Define Analysis Threshold Network Automation with Qapp Its easy to program a Qapp to run at any frequency. NetBrain will automatically collect and chart any type of data you're looking for. Automated Data Analysis Example Qapp Output To raise an alarm, users can indicate a threshold condition and associated warning message which is raised if a variable exceeds the threshold. Step 3: Define Data Positions on Map Define Alert Thresholds Network Automation with Qapp If any data point exceeds a pre-defined threshold, NetBrain can automatically generate an alert and send an email. A Qapp uses the map to display the desiered device and interface data. The positions of the data on the map are easily defined during Qapp definition. Example Qapp Data Define Data Positions 21 22
