Home workers can leverageadditional bandwidth and IT gains visibility into theentire network. Critical workers such as power users,execs and call center reps have redundancy andresiliency. Adding network redundancy greatly4reduces the risk of outages as a single link, evenwith Service Level Agreements (SLAs), can stillexperience congestion and outages.Improve real-time traffic performance for voice andvideo that is sensitive to congested networks, latencyand jitter can stop robotic voice, audio dropouts, poorvideo and dropped calls.

Citrix SD-WAN providesconsistent WAN administration across major clouds andspeeds up site rollouts while lowering transport costs.Accelerate journey to SASEThe shift to SaaS and cloud necessitates directinternet access as backhauling is inefficient andresults in a degraded user experience. Networkand security integration at the edge protects theuser experience while preventing threats fromentering through the network.

De-duplication and caching reduce traffic across theWAN. Compression reduces band width consumption and increasesdata throughput.TCP optimization reduces overhead.Traffic ForwardingPacket-based trafficforwardingData is delivered on a per packet basis. Packet-based forwardingreorders packets to mitigate changing WAN conditions in order tobest steer traffic.Maximize BandwidthUsageVirtual WANMaximize bandwidth usage (even for a single TCP session over2 or more WAN links). To ensure high application performancefor bandwidth intensive applications such as backups and large filetransfers, multiple links are used simultaneously for a single session.If the bandwidth required for one session exceeds the availablebandwidth on the best link, all the available bandwidth on the bestlink will be bonded with the second-best quality link.This lets highbandwidth applications have as much bandwidth as they need toperform optimally.Dual-ended QoSDual-ended QoSDual-ended QoS measures latency, packet loss and jitter at both thesending end and destination. Administrators configure QoS globallyfrom a single source and senders only send at the peers advertisedreceive rate. Unidirectional local measurements are shared with peerdevices in the network. All sites get their fair share of bandwidthpreventing oversubscription and wasted utilization.
Citrix SD-WAN Data entQoS (Detection, avoidance,remediation)A fourth measurement of QoS is congestion. Tunnels betweenappliances allow for proactive management of the traffic. Thesending appliance tags each packet with information about thetime sent and its order in the packet. The receiving appliance readsthese tags and uses the data to measure transit time, congestion,jitter, packet loss, and other information about the performanceand health of the path in each direction. The appliances share thisinformation with the controller, which uses queuing theory andpredictive behavioral statistical modeling to create a “map” of allof the paths in the WAN. The map is continuously updated withinformation from recent packets.Packet LossConcealmentQoSPacket DuplicationTCP OptimizationSelective Acknowledgment (SACK) is a strategy which corrects thisbehavior in the face of multiple dropped segments. With selectiveacknowledgments, the data receiver can inform the sender aboutall segments that have arrived successfully, so the sender needretransmit only the segments that have actually been lost.Note: Can be applied to UDP flows/data.Latency MitigationDPIDIAIntelligentpath selectionIntelligent detection of the most optimal low-latency routes isachieved by creating a VPN overlay. Additionally, extending thenetwork to the cloud with automated on-ramps and direct breakoutremoves the need to backhaul that traffic reducing the distance ithas to travel.Selective PacketDuplicationPacket DuplicationPacket duplication, or racing, ensures high application performance forreal-time applications such as voice by duplicating a session’s trafficacross multiple paths. This means that no packets are lost and, as thefirst of the duplicate pair to arrive is used, each packet takes the lowestlatency route. This allows for optimal application performance for justa small cost in bandwidth. It is ideal for improving media quality withsoftphones and Unified Communications apps. From an HDX perspective,a softphone/UC app can be “optimized” (the media engine runs on theuser device, offloading the Citrix server) or “unoptimized” (media isprocessed on the Citrix server and delivered over ICA). Packet racingcan be used in either case.HDX Session FairnessHDX Session FairnessSession fairness ensures that no single HDX user consumesmorethan a fair share of the available network bandwidth. Userscontinue to enjoy a responsive, interactive experience even whensomeone in the same office is transferring a huge file or printing alarge graphics-intensive document.Link FailoverLink FailoverSD-WAN will initially select the best path for each type ofapplication based on an algorithm that takes in to account
