How Converting Unicast into Multicast Can Optimize Your Network

Posted · Add Comment


*This is the first of a four-part series highlighting the various features of Syn-Apps’ patented Paging Relay.

Paging Relay Product Spotlight

Syn-Apps’ Paging Relay is a small, patented PoE network appliance that provides customers with a number of communication solutions. It enables connectivity to analog endpoints, contact closure devices, alarm panels and more. The device can also be used to configure remote site failover, broadcast background music, play music on hold, and alert staff of incoming calls after business hours with the night ringer functionality.

One key feature of the Paging Relay is its ability to significantly reduce bandwidth consumption by converting incoming unicast audio streams into multicast to destination sites across the WAN.

Feature of the Week – Unicast to Multicast Conversion

What is unicast?

Unicast is an industry-standard transmission method of sending data to a single network destination identified by a unique IP address.

What is multicast?

Multicast sends one data stream to multiple endpoints and optimizes network performance by controlling network traffic and reducing the bandwidth load on network devices.

How Can Syn-Apps’ Paging Relay Help?

By converting a single unicast stream into multicast before delivering a notification, the Paging Relay decreases network bandwidth and provides clear, crisp audio announcements to designated endpoints — like IP phones, IP speakers, or traditional PA systems.

Above: One Unicast stream is sent from the server to the Paging Relay. The Relay converts the stream to Multicast and sends individual streams to the endpoints.

Ask yourself this: Could your organization benefit from taking additional measures to optimize your network – such as reducing bandwidth consumption or broadcasting intelligible audio notifications?
