`Talari Difference
`
`Talari | SDWAN Innovator and Leader
`
`As companies search for a better way to WAN, it can be hard to differentiate one product from another. Link aggregation, load balancing, path control,
`traffic steering and failover solutions are offered in different forms from different vendors. When assessing these offerings, it’s important to understand
`what separates Talari from the crowd.
`
`Quality–based routing
`
`Other products include policybased routing, which allows an administrator to predetermine paths based on assumptions about bandwidth or latency. But
`the real network rarely conforms to predefined assumptions. Talari is the only technology that combines predetermined policies with up to the millisecond
`knowledge of the actual network performance, creating a thinking network to ensure application quality.
`
`What does this mean?
`
`It’s the difference between saying “put my VoIP traffic on my MPLS link because it ought to be better” and “treat my VoIP as high priority and do
`whatever you need to do to make sure that my calls are always clear, never drop, and are never crowded out by lower priority applications.”
`
`Oneway assessments of true quality
`
`Some companies purport to base path decision on quality, while only measuring latency via round trip ping. But latency is only one dimension of a complex
`quality assessment and round trip measurement ignores the fact that traffic can take different routes in each direction. And those directions can vary
`drastically in latency, bandwidth, and loss. Talari measure the loss, latency and jitter of every path in each direction to create a complete and nuanced
`network map. Using this information, path decisions can be made intelligently and with full knowledge and awareness.
`
`What does this mean?
`
`Applications with asymmetric traffic such as VDI can actually perform worse by being sent on a link that looks good when only round trip latency is
`considered. With Talari, users will experience responsive application performance without the lag that leads to complaints, session disconnects, and
`lost productivity.
`
`Intelligent load balancing
`
`Load balancing designed to make better use of available bandwidth is a key element in WAN design. But not all load balancing is created equal. The most
`simplistic load balancing assigns individual sessions to a path, often without regard to link characteristics and application requirements. More sophisticated
`ones balance by the packet. But both of these approaches will result in poor application quality in cases with dissimilar links. For example, in aggregating
`MPLS link with Cable, the latency and bandwidth between the two will vary widely and unpredictably and the corresponding application performance will as
`well. Packet load balancing without intelligence can result in out of order packets and high loss and the resulting retransmits can cause worse performance
`than no load balancing at all. Talari’s intelligent load balancing spreads a single session across multiple links only when the end result will be improved
`performance. It also adapts to changing conditions and moves packets off links as quality degrades or links fail without disrupting the session. And its loss
`mitigation and reorder control compensates for dissimilar link characteristics.
`
`What does this mean?
`
`With Talari, all available bandwidth is used, resulting in a reduction in congestion and a corresponding improvement in application performance,
`regardless of the type of underlying links and regardless of the application mix. Quality sensitive applications remain on high quality paths and bulk
`transfers complete faster by using aggregated link capacity without displacing high priority traffic.
`
`Packet duplication
`
`A feature unique to Talari’s solution is selective packet duplication. The packets from low bandwidth, latency sensitive applications such as VoIP can be
`duplicated across two or more links. This trades off bandwidth for predictable application performance and results in the highest possible application
`performance and quality.
`
`What does this mean?
`
`As bandwidth cost decreases, companies can use less expensive and abundant bandwidth and still be assured of excellent application quality for the
`highest priority applications. If high voice quality or peak ERP application performance is a business necessity, Talari’s WAN solution with packet
`duplication will help achieve it.

`Failover without session interruption
`
`Talari | SDWAN Innovator and Leader
`
`Failing over to a backup link when a primary WAN link fails is baseline functionality in many products. Even routing protocols can accomplish this in a
`simplistic way. The key issues are how long it takes, what happens to active sessions, what constitutes a failure, how traffic is prioritized in the resulting
`bandwidth constrained network and how session flapping is prevented when the link begins to recover. With Talari, the failure is detected within a fraction
`of a second and traffic is moved to the remaining live links without any interruption to active sessions. And with Talari it doesn’t require a full failure to
`initiate traffic changes – even high latency, packet loss, and jitter will result in Talari proactively steering packets around the problem. If the remaining links
`don’t have enough bandwidth, traffic is prioritized and cached according to company policies and prioritization so that mission critical applications continue
`to function. And with Talari, recovery avoids the flapping that often occurs when a link is reestablished.
`
`What does this mean?
`
`Users won’t notice outages. Business will continue without interruption. And corrective actions with a service provider can be undertaken after the fact
`and without it being a crisis.
