Managing a Widely Distributed Network

639 views

Published on

Your network is your business, so downtime and performance degradations are mission-critical problems, affecting productivity, revenue, and relationships with customers and partners. Combine this with a widely distributed workforce and the accompanying widely distributed network infrastructure of most modern companies, and the challenges of real-time network management and troubleshooting seem overwhelming. However, by building distributed, intelligent network analysis that includes your remote offices, vital information for management and troubleshooting is always at your fingertips.

WildPackets is leading the charge with its Omni Distributed Analysis Platform. Join this webinar to see how WildPackets provides visibility across your entire network, from data centers to remote offices, providing highly distributed network analysis and troubleshooting with a single, distributed cost-effective solution.

  3. 3. © WildPackets, Inc.#wp_NetworkAnalysis 3 Agenda • Goals and Challenges • Monitoring Application Performance • Network Analysis Architecture in a Distributed World • Using Network Analysis for Application Performance Monitoring • Industry-leading WildPackets Solution
  4. 4. www.wildpackets.com© WildPackets, Inc. Distributed Network Monitoring Goals and Challenges
  5. 5. © WildPackets, Inc.#wp_NetworkAnalysis 5 By the Numbers • 64% of organizations reported that managing network performance has become more complex over last 12 months • Organizations are losing on average $72,000 per minute of unplanned network downtime • 48% of organizations reported that, on average, they spend more than 60 minutes on repairing performance issues - per incident

  8. 8. © WildPackets, Inc.#wp_NetworkAnalysis 8 Key Challenges for Network Performance Management 29% 29% 35% 36% 41% 46% Inability to identify potential performance issues when designing the network Difficulty determining next steps to take when a problem is detected Oversubscribed network monitoring tools Lack of visibility into the business impact of network performance Lack of visibility into application performance Inability to identify root cause of performance problems in a timely manner
  9. 9. © WildPackets, Inc.#wp_NetworkAnalysis 9 Summary and Key Takeaways • Network is becoming more of a strategic asset • Traditional tools are not as effective in managing high speed networks • Proactive management of network performance results in measurable business benefits • Organizations are looking to improve their ability for managing performance of VoIP and other real-time applications • Quality of user experience is becoming a key metric for monitoring network performance
  10. 10. www.wildpackets.com© WildPackets, Inc. Monitoring Application Performance
  11. 11. © WildPackets, Inc.#wp_NetworkAnalysis 11 It’s All About The User Application Response Time – The time it takes an application to respond to a specific user request, measured from the user’s perspective 3 Performance Levels of User Satisfaction
  12. 12. © WildPackets, Inc.#wp_NetworkAnalysis 12 A Bit More Precisely … Application Response Time = Network Response Time + Transaction Response Time
  13. 13. © WildPackets, Inc.#wp_NetworkAnalysis 13 Network Response Time • Network Response Time (R): Time between a user’s action and the network’s response to that action • Payload: Information content in bytes • Bandwidth: Minimal link speed between client and server • AppTurns: Number of interactions needed between the client and server to provide a response to the user • Round Trip Response Time (RTT): Propagation time for data between the client and server Network Response Time (R) ~ (payload/bandwidth) + [AppTurns*RTT] Adapted from Peter Sevcik and Rebecca Wetzel of NetForecast
  14. 14. © WildPackets, Inc.#wp_NetworkAnalysis 14 Other Network Response Time Considerations • NRT is dynamic, never a constant • DNS response time is a common source of performance issues • Proxy servers – TCP connection is not end-to-end to the server • Multi-tier designs – network latency between each tier
  15. 15. © WildPackets, Inc.#wp_NetworkAnalysis 15 Transaction Response Time • Server Response Time (SRT): Processing time required by the server • Client Response Time (CRT): Processing time required by the client Transaction Response Time (TRT) ~ Server Response Time (SRT) + Client Response Time (CRT) Adapted from Peter Sevcik and Rebecca Wetzel of NetForecast
  16. 16. © WildPackets, Inc.#wp_NetworkAnalysis 16 Transaction Response Time Factors • Server Latency: Time for the server to process a request - memory, disk system, CPU, and usage dependent • Application Latency: Time for the application itself to process the request – mostly software design dependent • Database Latency: Database design factors that contribute to overall processing time – eg. fragmentation, indexing, etc. • Browser/Workstation Latency: The client side of the equation • Protocol Usage: Some protocols outperform others
  17. 17. © WildPackets, Inc.#wp_NetworkAnalysis 17 It’s All About The User Application Response Time ~ (payload/bandwidth) + [AppTurns*RTT] + SRT + CRT 3 Performance Levels of User Satisfaction

  25. 25. © WildPackets, Inc.#wp_NetworkAnalysis 25 The Challenges • Store every single packet with no packet loss • Provide critical network health statistics in real-time • Generate comprehensive analytics for in-depth post- capture analysis and data retrieval • Ensure packet access for deep packet inspection and complete troubleshooting • And do it all FAST like the network itself Importance: Packet-based PM tools remain only truly effective approach to definitive monitoring and definitive troubleshooting – Jim Frey, Enterprise Management Associates, Inc.

  27. 27. © WildPackets, Inc.#wp_NetworkAnalysis 27 10G Network Data Capture
  28. 28. © WildPackets, Inc.#wp_NetworkAnalysis 28 10G Network Data Storage • 1Gbps steady-state traffic assuming no storage overhead: 7.68 GB/min 460 GB/hr 11 TB/day 2.9 days in a 32TB appliance • 10Gbps: 76.8GB/min 4.6 TB/hr 110 TB/day 7.0 hours in a 32TB appliance
  29. 29. © WildPackets, Inc.#wp_NetworkAnalysis 29 Different Approaches, Different Results • Client side ‒ Closest to what the user sees ‒ Difficult to troubleshoot delays ‒ Requires monitoring equipment at all remote sites + centralized monitoring – expensive • Server-side ‒ RTT harder to determine ‒ Consolidation of monitoring equipment ‒ Better able to assess server response time
  30. 30. © WildPackets, Inc.#wp_NetworkAnalysis 30 Multi-Segment Analysis (MSA) Compare simultaneous data from end to end ‒ A single point only tells you flow health ‒ Multiple points measure link quality
  31. 31. © WildPackets, Inc.#wp_NetworkAnalysis 31 The WildPackets Solution • Intelligent, dynamic load-balancing, filtering and time-stamping of highly-utilized network traffic ‒ To capture and store every single packet ‒ To eliminate capturing unnecessary traffic ‒ To provide high precision time-stamping for accurate latency measurement and time synchronization • Gather high-level, flow-based statistics ‒ To monitor the network health ‒ To narrow down post-capture analysis criteria • Make packets readily and quickly available ‒ To provide in-depth troubleshooting and deep packet inspection • Aggregate and display the load-balanced traffic in a single view ‒ To make it trivial for the user to monitor, analyze, and troubleshoot demanding networks
  32. 32. www.wildpackets.com© WildPackets, Inc. Using Network Analysis for Application Performance Monitoring
  33. 33. © WildPackets, Inc.#wp_NetworkAnalysis 33 The Network Or The Application? Possible Issues on the Network Possible Issues with the Application
  34. 34. © WildPackets, Inc.#wp_NetworkAnalysis 34 Expert Analysis Leads The Way Network may be at fault System or Application is at fault
  35. 35. © WildPackets, Inc.#wp_NetworkAnalysis 35 What To Look For • Primary events are anything related to “slow” ‒ Depending on what events we see, we will know who is at fault • Typical application events: ‒ HTTP slow response time ‒ Oracle slow response time ‒ Inefficient client • Typical network events: ‒ TCP SLOW segment recovery ‒ Slow retransmissions ‒ Slow acknowledgements ‒ Low throughput
  36. 36. © WildPackets, Inc.#wp_NetworkAnalysis 36 Visual Expert Provides Proof Two requests for data, two quick TCP Acks, but then a long delay before the server sends the requested data Requests and Acks Then the Data gets returned much later ACK fast = Network fast Data slow = System slow
