  1. Accelerate & optimize Any APP Rick Suehring, Regional Sales Manager rsuehring@silver-peak.com

  2. “The network dictates the end user experience” Gartner group 2014

  3. Wan vs. lan Latency, Packet Loss, Out-of-Order Packets, Congestion

  4. Why is a wan not like a lan? LAN WAN LATENCY LATENCY 20-300ms ~1ms LOSS LOSS MPLS 0.1% - 2% METRO ETHERNET 0.1% - 2% IP VPN 1.0% - 8.0% None CONGESTION CONGESTION $/Port = High $/Port = low

  5. LAN LIKE Quality comes at a high cost Private lines, dark fiber • Latency • Loss • Congestion

  6. Lower Cost links makes a wan feel like a … wan MPLS, IP-VPN, Metro ethernet • Latency • Loss • Congestion

  7. Latency – slows communications across wan LAN WAN Transmit Transmit Ack Ack Latency 1ms Total 4ms Latency 100ms Total 400ms

  8. Latency effect on throughput Calculating Throughput Receive Window Size ≤ Throughput Round Trip Time The equation never asks for the bandwidth size! Mbps Performance of an application across the WAN is always dependent on the latency. Latency

  9. what about the storage guys? Gigabytes Per Hour Latency between locations has everything to do with how much traffic can be replicated. Latency

  10. Packet loss • Caused by carrier congestion and SLA • When packets are lost TCP window sized reduce by ½ • Lost packets must be retransmitted Request Retransmit 1 4 5 2 3 Packet Lost

  11. We did the math for you! • Effective throughput with loss Mbps % Loss From: NetForecast, “Improving Effective WAN Throughput for Large Data Flows, by Peter Sevcik and Rebecca Wetzel, Nov 2008 (http://bit.ly/12aL3gt)

  12. Out-of-order packets • Caused by packets taking different routes • Out-of-Order packets cause retransmission • TCP window reduced to ensure reliability 1 4 2 3 Detect Out-of-Order Request Retransmit

  13. WHAT DO YOU REALLY GET? • Latency, Packet Loss & Out-of-Order Packets • Packet retransmission slows down TCP connections and degrades UDP What you pay for What you actually experience

  14. CONGESTION EVERY APPLICATION crosses the wan Collaboration Disaster Recovery Server Centralization • Storage Replication • Remote Backup • Failover to Cloud • Email • SharePoint • File Servers • AD, DNS • Internet • VoIP • Video Conferencing • Screen Sharing • VDI • Printing

  15. The silver peak approach OPTIMIZE AND CONDITION THE WAN

  16. The solution Apply 1 or all 3 techniques LATENCY NETWORK ACCELERATION EXTEND DISTANCE Mitigate protocol latency and chattiness NETWORK INTEGRITY LOSS • FIX CONGESTION / PACKET LOSS • • Traffic Shaping/Quality of Service (QoS) • • Forward Error Correction (FEC) • Packet Order Correction (POC) CONGESTION TM NETWORK MEMORY INCREASE BANDWIDTH Real-Time deduplication of all IP traffic

  17. Overcome latency Without Network Acceleration With Network Acceleration Total time: 100 ms Total time: 500 ms Transmit Transmit Ack Ack • *Latency is determined by: • Speed of light • Route taken • Congestion in network Latency 100 ms* Latency 100 ms*

  18. eliminate packet loss • Parity dynamically adjusted based on amount of loss • Lost packets rebuilt at the receiving Silver Peak • Receiver unaware packet loss has occurred • No window size decrease Lost Packet Rebuilt from Parity 1 4 5 2 3 Packet Lost P

  19. correcting out-of-order packets • Packets are tagged as they leave the Silver Peak • Out-of-Order packets are reordered at the receiving side • Receiving client unaware that out-of-order packets have occurred • No window size decrease 1 1 4 4 2 2 3 3 Detect Out-of-Order Reorder

  20. Clearing congestion Layer 3 Byte level deduplication 1. Byte Fingerprint & Store 3. Byte Fingerprint & Store Not Cached 2. Compress + Transmit 4. Uncompress & Deliver 1. Byte Fingerprint Match 3. Get Local Data from Cache Cached 2. Send Retrieve Instructions 4. Deliver

  21. The silver peak approach Optimize Anything

  22. WANOP background Gen 1 • Packet Shaping • QOS Gen 2 • Designed for TCP only • Optimize a select set of applications Gen 3 • Optimize all protocols • Optimize any application • Correct for WAN problems

  23. Application acceleration Legacy wan optimization, Gen 1 and Gen2 Bulk TCP Real-Time TCP Bulk UDP Real-Time UDP Proprietary/ Encapsulated File CIFS, NFS, FTP, AFS Web HTTP/S, SharePoint Email Exchange, Notes, SMTP Data Replication SnapMirror, Celerra, HNAS, EqualLogic, etc. Remote Backup VDI MSFT RDP, Citrix ICA SQL Queries MS, Oracle, Sybase, etc. Data Replication SRDF,RecoverPoint, HUR, Compellent, etc. Video Streaming DNS File, NFS Aspera VMware Replication VoIP Video conferencing Streaming data VDI PCoIP VMware Lync IP – IP GRE RTP RDP IP v6 in IPv4 FCIP VPLEX Cisco OTV UDP – Layer 4 (Transport) TCP – Layer 4 (Transport) IP – Layer 3 (Network)

  24. Network Acceleration & optimization Generation 3 – Optimize anything Bulk TCP Real-Time TCP Bulk UDP Real-Time UDP Proprietary/ Encapsulated File CIFS, NFS, FTP, AFS Web HTTP/S, SharePoint Email Exchange, Notes, SMTP Data Replication SnapMirror, Celerra, HNAS, EqualLogic, etc. Remote Backup VDI MSFT RDP, Citrix ICA SQL Queries MS, Oracle, Sybase, etc. Data Replication SRDF,RecoverPoint, HUR, Compellent, etc. Video Streaming DNS File, NFS Aspera VMware Replication VoIP Video conferencing Streaming data VDI PCoIP VMware Lync IP – IP GRE RTP RDP IP v6 in IPv4 FCIP VPLEX Cisco OTV UDP – Layer 4 (Transport) TCP – Layer 4 (Transport) IP – Layer 3 (Network)

  25. What does it really mean? LAYER 4-7 • Only optimize specific set applications • Coordinate software upgrades with WANOP appliance version to avoid breaking applications and optimization • Unsupported applications can break LAYER 3 • Set & forget - Optimize ANY & ALL traffic • Fix network health issues, accelerates & deduplicates • Optimization is 100% independent of the application or version

  26. Thank you
