SD-WAN, SDN, NFV

With SD-WAN, we understand the importance of tracking issues and staying on top of carrier-related items, including any sort of routing issues that could be occurring. With most SD-WAN solutions currently utilizing dual WAN at minimum, we realize that many of the “self-healing” aspects of SD-WAN can be compromised when links go down—making it incredibly important that, as a NOC support provider, we’re quickly able to identify what that issue is and accelerate resolution.

Are we dealing with a BGP peering issue? Are we dealing with a fiber cut? Are we dealing with something going on within a carrier's network that we need to pursue with them to restore that redundancy and the system's operation? We also have the ability to support a variety of overlay items within this space, such as the quality-of-service features that SD-WAN brings, as well as logical connectivity and complex configuration items.

We also provide NFV support—standard network functions that have now been virtualized—to our service providers in much the same way we support a standard physical switch or router. Most of these are supported by golden images. They're running VMs on a server, within a client’s premises, in the cloud, or on white boxes that have VMs running on them that customers can purchase—governed by an orchestrator of some sort.

Central software or applications are typically used to facilitate the management of these VN apps and SD-WAN solutions or their counterparts. We utilize these platforms for management as well as for troubleshooting to quickly investigate and identify, for example, which VMs may be currently down. Perhaps the VM is up and there's an issue within the software that's running on it and affecting the switches. Perhaps a router is having issues. Whether it’s port mappings, bridges, or virtual switches that take place from the server to VM component of that, we have a wide breadth of support capabilities.
