    2. Packet Design - 2004 1 Packet Design, Inc.

    3. Packet Design - 2004 2 Today’s Network Problems Over half of performance & downtime events are directly related to routing problems [source: University of Michigan] Over 50% of these routing problems are “Logical” failures The critical point of failure is the network’s routing protocol. Logical failures such as misconfigurations, protocol errors & software bugs contribute over 25% of network problems [source: University of Michigan] Logical Routing Problems are hard to find and repair On average the MTTR of these events exceed 30 minutes [source: University of Michigan] For large enterprises 30 minutes = $3 Million [Roland Berger 2001] Savings of at least $1M annually for Market data distribution [Iverson Financial] Solution can reduce the MTTR to seconds Can provide early warning BEFORE problems lead to downtime Only solution to provide Root-Cause visibility in IP Networks IP availability – not network gear availability – is the primary measure of Service Level Agreements!

    7. Packet Design - 2004 6 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

    9. Packet Design - 2004 8 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

    10. Packet Design - 2004 9 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 customer’s 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 (doesn’t miss events between polling cycles) Captures 100% of events for detailed root cause analysis

    11. Packet Design - 2004 10 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
