Miercom Check endorses Cisco SD-WAN’s Higher Availability and Best Route optimization capabilities.
To experience a resilient network, it is very important maintain higher availability not merely in control plane, but at the info plane for visitors to flow smoothly also, without any disruptions. In case of unavailability of manage plane, which governs and manages the info plane traffic, the complete WAN infrastructure and subsequent web site traffic can decrease, causing massive outages. The SD-WAN remedy ought to be intelligent enough never to only ensure continuous information plane operation, but additionally to supply an optimized route for the application form traffic for enhanced consumer experience.
Cisco SD-WAN provides faster hyperlink convergence, whenever the principal link fails, ensuring there’s zero downtime on the specific traffic flowing over the network. After the IPsec Tunnels are usually ready to go, data plane traffic doesn’t have any dependency on the manage plane. This means, that even though the online connectivity from the edge gadgets to regulate plane is down, visitors between your IPsec established websites will stay up and running.
It has been tested and verified by Miercom, wherein following scenarios were recreated:
In both full cases, before decreasing the control connection, Miercom verified that IPSec Online connectivity is and operating up. Post verification, once the control hyperlinks down were shut, it had been observed that traffic stream had not been impacted, and IPSec tunnels remained up and operational. It had been noticed that Cisco SD-WAN didn’t require any guide intervention for failover in both scenarios.
Aside from providing link degree resiliency for maintaining continuous circulation of data visitors, Cisco SD-WAN also provides best route optimization based on the SLAs defined within the application policies. It’s been examined and verified that when the primary link falls or if the SLA parameters such as for example latency, delay, jitter are usually compromised compared to what has already been described in the routing plans, the application form traffic automatically failover to the secondary hyperlink then.
In comparison to this kind of resilient SD-WAN architecture by Cisco, our competitor didn’t provide higher availability and disruption-free information flow. The comparable scenarios had been recreated and examined on our competitor’s solution. It’s been observed that there surely is 10 seconds of visitors disruption during failover tests approximately, causing mission critical apps such as for example financial or banking program to proceed offline for an excellent amount of time.
Furthermore, from overall architecture viewpoint, our competitor provides dependency upon cloud hosted controller and you can find fixed ports within their edge devices make it possible for such connection. Therefore, if the particular ports are removed for disconnecting the controller conversation, the edge devices may also move offline disrupting the complete network.
By evaluating the performance and efficiency for both solutions, Miercom figured Cisco SD-WAN provides extremely scalable system architecture, which enables car failover of visitors circuits, as so when require arise. This makes certain that end users aren’t impacted because of any disruptions due to hyperlink flapping or degraded circuit efficiency. Cisco SD-WAN always means that the application traffic will be routed through the very best optimized path, offering best user experience.
