Todays Network Problems

• Most network problems go beyond device and
  connectivity issues they are often
  layer-3/logical issues (59)
• Most layer-3 problems diagnosed by network
  engineers using CLI into one router at a time
• Traditional management tools manage from the
  outside looking in, they dont have visibility
  into the IP forwarding decisions
• Traditional management tools are based on
  periodic polling, and dont see the network in
  real-time or record relevant history

Todays View of IP Clouds
Network Managers have no idea what really goes on
inside the cloud

• Networks today are
• planned
• built
• provisioned
• managed
• as devices

Route Analytics Defined

• Route Analytics leverages routing protocols to
  analyze and monitor dynamic network behavior,
  enhancing current element and physical
  connectivity management to drive service
  assurance
• Resides on the network as a passive router
• Forwards no traffic, not a failure point
• Listens as the routers talk to each other via
  control plane
• No polling
• Uses advanced analysis to construct dynamic
  network topology
• Determines routing changes as the routers do
  reports failures as routers announce them
• Real-time, at the speed of the network
• Focuses diagnostics on relevant routes and
  devices for superior root cause analysis
• Solves heretofore elusive problems at the network
  or routing layer
• Extremely scalable, scaling as routers themselves
  do

Route Analytics Applied

• Real-time, unified view of network, regardless of
  protocol or topology
• Can build dynamic network view from a single
  physical vantage point
• No polling scalable minimal overhead
• Very accurate, with historical data
• Easy to deploy, non-intrusive

Route Analytics for BGP/MPLS VPNs

• Manages BGP/MPLS VPNs from Layer 3 perspective
• Leverages Multi-protocol BGP (MP-BGP)
• New VPN-specific analyses, reports, alerts
• Dynamically tracks all VPN routing information
  offers real-time, per customer views of
• VPN routing topology overlay
• Reachability between customers sites
• Potential privacy violations
• Site-to-site routing policies
• Complements existing VPN management tools while
  providing all the benefits of route analytics
  technology
• No overhead / easily scalable
• Unparalleled accuracy (doesnt miss events
  between polling cycles)
• Captures 100 of events for detailed root cause
  analysis

BGP Root-Cause Analysis

• Determines root cause(s) even when there are
  multiple, simultaneous failures
• Identifies underlying causes in an event stream
  from million event-per-second major peering
  losses to one event-per-day customer route flaps
• Works for any BGP topology from a simple
  enterprise single ISP peering up to a major ISP's
  entire BGP core mesh
