SkySwitch n-Share Architecture

The SkySwitch platform uses always-available n-Share clusters co-located in geographically diverse data centers.

Most high-availability or n+1 redundancy schemes rely on a primary and failover node. In contrast, the n-Share system is Always Available.  That means that we provide identical service across multiple locations in real-time. With seamless and transparent failover between nodes, service disruptions are avoided because customer connections are automatically transferred to any nodes available.

So, a voicemail can be left on a Dallas feature server, and retrieved on the New York server immediately, even if the Dallas server is no longer available. It also means that feature options (such as call-forwarding or other * codes) take effect across all servers immediately.

As network traffic grows, SkySwitch adds capacity by deploying additional n-Share nodes. Newly added nodes are added to the n-Share mesh and automatically become available to share call processing tasks across all nodes dynamically and with zero downtime.  This means that we can expand to accommodate Reseller growth with zero impact on the availability of services to end users.

Where other high-availability schemes require the use of active and standby servers (with the standby servers left idle in readiness for a problem) n-Share creates efficiencies by dynamically distributing load across all available servers. This means that load can be dynamically shared across all connected nodes based on geographic distance from the user. Especially in cases where media-anchoring is required, this optimizes quality of service by ensuring voice and video payload will take the shortest path between the sender and receiver.

Mobile workers are now using SIP mobility clients (such as the PBX Fone mobile client) running over 3G and 4G wireless networks, where network conditions are often unpredictable. As a result, the ability to maximize quality of service in a scalable and reliable way is becoming more important than ever.  On that front, SkySwitch has you covered.


The SkySwitch Device Provisioning Server simplifies the management of SIP end-user devices by significantly accelerating device registration and deployment.  With built-in support for all major device vendors, it delivers unparalleled ease of management  to Resellers and zero-touch device configuration and customization for end users.
