How SD-WAN Makes UC Apps Dance The Leader in Failsafe SD-WANs May 17, 2018 @AtchisonFrazer 1 Top 10 Coolest SDN Technologies
Cloud is Changing Enterprise IT Traditional WAN solutions + WAN Opt no longer cut it doesn t do cloud, locks you into a carrier, and is incredibly expensive bits literally 50x 400x more expensive vs aggregated bits WAN Optimization offers less benefit over high bandwidth, unpredictable connections SoHo Branch ISP ISP ISP ISP ISP Data Center Regional/HQ The migration of enterprise applications to the cloud rendering traditional WAN architectures obsolete 2
SD-WANs Offer Tremendous Promise Common elements across many SD-WAN implementations Flexible, secure virtual WAN overlay Leverage links Support for multiple WAN links Lower costs (than -only WAN) Centralized controller / orchestration / policy control ZTP deployment; simpler ongoing management Branch office simplification capabilities Cloud connectivity Choice of physical and/or virtual appliances scale Policy VAN Ink Reliability management aggregation WAN Costs VAN Reliability Reliability Private Cloud Ink Unpredictable Virtual WAN overlay End-to-end QoS aggregation WAN scale Volp Policy Carrier - VAN High availability agnostic scale visibility management Reliability Control & Security End-to-end QoS VAN Virtual WAN overlay End-to-end QoS Control Policy control scale Carrier - Analytics scale Centralized controller Reliability WAN Optimization Ink aggregation Policy management SD - WAN agnostic Carrier - QoE agnostic Cloud scale Reliability Secure High availability Centralized controller Migration End-to-end QoS VolP Failsafe High availability scale Private Cloud QoE Branch scale High availability VAN Cloud Connectivity Carrier - agnostic simplification Cloud Migration No forklift upgrades VAN Virtual WAN overlay Hybrid cloud Hybrid WAN QoE Unidirectional measurement Application Identification Virtual WAN overlay Cloud Migration End-to-end QoS VAN End-to-end QoS SaaS QoE Cloud Migration Cloud Migration QoE Hybrid cloud Data Center SoHo Location Branch Office TALARI Servers Core Cloud Data Center SaaS 3

Talari Failsafe SD-WAN Technology Continuous, unidirectional measurement... The Keys... enabling per-packet forwarding decisions and sub-second response to adapt to network events Other Key Tech Intelligent Link Aggregation Use all bandwidth across disparate links, even for a single flow Packet Replication Platinum-quality real-time support Inbound Multisource QoS Sustain 90%+ link utilization without negatively impacting QoE Centralized orchestration/analytics Ease of management, with unprecedented WAN visibility Scales to large WANs Easy to scale if you don t deliver failsafe; not easy at all when you do 9
Failsafe Reliability: It Starts with Measurement Continuous, unidirectional measurement of all [m x n + p]* paths between any two locations Loss Jitter Latency Bandwidth Utilization ISP A ISP B ISP C ISP D Loss Jitter Latency Bandwidth Utilization Up-to-the-instant complete knowledge of the state of the WAN 10 m = # of links at first site n = # links at second site p = # of distinct Classes of Service available
Sub-second Response to Network Issues Per-packet forwarding decisions and fast reaction based on network state now Talari Reliable Protocol (TRP) ensures packets reliably get to where they need to go Lost TCP packets quickly retransmitted Packets delivered in-order to receiving host Traffic moved to different path, sub-second, if high loss or excessive latency detected Bad paths not used until their loss/latency gets better WAN always looks zero loss (with occasional high jitter) to all TCP apps, maximizing performance ISP A ISP B ISP C ISP D Optimize the multi-layer network fabric for all applications Don t map applications to WAN connections; apply app policies and let the SD-WAN deliver 11
Intelligent Link Aggregation Send traffic through conduit (aggregation of paths) to get it to the other end as quickly as possible Use all bandwidth even for a single TCP flow Each packet queued for path that will get it to WAN destination most quickly given current path latencies Per-packet load balancing all the bandwidth efficiency advantages, without the historical downsides Conduits take advantage of all links, even ones with widely differing bandwidths and latencies ISP A ISP B ISP C ISP D Combines session, path and WAN link intelligence to best use all available bandwidth 12
Packet Replication Platinum Quality of Experience (QoE) support Optionally replicate flows on two best paths for platinum results Ordinary TRP sub-second response already provides excellent QoE Replication minimizes jitter; essentially eliminates packet loss Receiving node discards duplicates ISP A ISP B ISP C ISP D Use Cases VoIP VDI (virtual desktop infrastructure) Videoconferencing (if enough available bandwidth) Trade cheap bandwidth for best, most predictable performance 13
Inbound Multisource QoS End-to-end QoS across the WAN via last mile congestion avoidance and bandwidth control Data Center Data Center Inbound Congestion Avoidance Branch Office SaaS/ Cloud SaaS ISSUE TCP by design overfills last mile pipe when receiving flows from different locations A problem when branch is accessing data/applications from multiple sources ANSWER Talari TRP naturally adapts quickly when stuff happens in the middle of the WAN Additional end-to-end QoS techniques, with sophisticated inbound congestion avoidance and corresponding last mile bandwidth reservation and control BENEFITS Avoid self-inflicted last mile inbound link congestion Enjoy 90%+ sustained link utilization without negatively impacting QoE Critical for supporting real-time apps, multi-data center/saas WANs over links 14
