Abacast Compared to Peer-to-Peer

Not like classic peer-to-peer Each user is in constant contact with the server for

real-time QoS monitoring Real-time redirection (no stale peer lists) Users do not know anything about each other Users do not store anything for each other Users are only distribute signal when actively

connected If the user needs their upstream bandwidth they

always have priority over Abacast distribution of the stream

Abacast technology has proven higher quality stream connections than standard unicast stream technology.

In side-by-side comparisons Abacast Enabled streams had fewer breaks, skips, or buffers than standard unicast streaming technology.

The result is that listeners and viewers stay connected to your streams longer and have better streaming experiences with fewer interruptions.
