TECHNICAL DATA

SurePath

SurePath’s agent-based technology closely replicates real-world applications to more accurately visualize your network paths.

Is the problem on my network, or someone else’s?

ENA v18.0 delivers both agent-based and agentless SurePath. Agent-based SurePath uses proprietary enhanced tcptraceroute to send packets to an endpoint destination, whether that endpoint is in your network or beyond, and gives you extended functionality so you can ensure network paths behave as best fits your network. Discover the path nodes that are causing high latency, so you can troubleshoot user problems across both private and public networks.

Specify

Required and blacklisting functionality enable you to specify which nodes must and must not appear in a path, and receive alerts when these are not met.

Focus

Optionally remove queueing latency along each hop in the path, so you can see just the routing delay at each node – the information you want to see.

Fix

Retain end-to-end path latency for historical insight and troubleshooting. Compare problems from the past with the present.

See through the cloud

Ever more applications and services are moving to the cloud. SurePath’s agent-based technology lets you monitor and troubleshoot network performance issues beyond the edge of your local network, and monitor SaaS connections from your network.

Aggregated traceroute batches ensure accuracy of path mapping, showing all possible paths a packet could have taken from source to destination.

N

Maintain application performance

Application performance management solutions cannot tell you where the problem is, but SurePath can. Quickly identify whether the problem is on your network or someone else’s, and locate potential and actual bottlenecks by seeing exactly how an application path travels through your network and the wider internet. Visual aids help narrow down where the problem might exist.

Further increase the accuracy of your network management by validating the performance of paths before deploying a new application, and troubleshoot current and historical issues to improve future performance.

+

Support critical connections

Continual visibility of critical paths, such as B2B and internet connections, help you meet increasingly demanding SLAs. Proactively prevent path deviations and accelerate troubleshooting to reduce the impact of degraded performance on end users. Ensure performance and connectivity to specific nodes and destinations, and monitor the performance links to remote WAN sites and branches.

Keep network paths resilient

Validate your network connectivity disaster recovery plans and protect IT operations in a trackable, accurate manner, complete with audit documentation. Be alerted when your primary WAN circuit fails over to a backup circuit, or when traffic goes over routes they should not go over.

Manage the routes you want paths to take

Use Required and Blacklist functionality to specify the nodes that you do and don’t want to see in a path. Receive event notifications when nodes that should be present are absent, and when nodes appear that should not – these help you correlate path change with performance issues.

For example, if you see high latency on a particular path, you can blacklist a node so that if it appears in future then you can be notified and try to fix it.

Simple visualization

The ENA UI simply and effectively visualizes your network paths and their data, so you can see everything you need to see. Select a path to open its Path Discovery dashlet, which is split into 3 sections to provide you with easily accessible data about each path through your network.

Path summary information bar

This provides at-a-glance summary details about the path, including status, latency thresholds, source and destination of the SurePath agent, and batch information.

Visual depiction of the discovered path

A visual depiction of the selected discovered path, its nodes, and the links between them. You have full flexibility as to how you view this path.

  • Choose whether to render the path horizontally left to right, or vertically top to bottom.
  • Zoom in and out as you need.
  • The name, IP address, and round trip time latency (inclusive or exclusive of queueing delays) of each node are displayed.
  • Instantly identify the first node in the path with latency issues, blacklisted nodes, and nodes in the public network.
  • Keep the path clean by collapsing internet nodes and hiding unknown nodes, or display every node and see the path in its entirety.
  • Click on a node to see its latency history for further data to help your path management.
  • View the specified required and blacklisted nodes for this path.

Historical timeline of path discoveries

View a historical bar chart of path discoveries, displayed as latency vs time, with each bar representing a batch discovey cycle and colored according to latency issues. Click a bar to display that path discovery’s visual depiction with all the functionality described above. Required and blacklisted nodes are updated to reflect the parameters of the selected historical batch.
