About SureStream
(continued)
Figure 5-2: Shows a typical configuration running SureStream on a single IP port
The configuration example above shows a typical SureStream configuration using two
SureStream component streams. This example uses the Internet with standard xDSL access
services. Diverse streaming on the internet has the effect, that the access routers treat each
SureStream component stream individually by passing it randomly on different paths to the
destination IP address.
On the receiving end, the Enhanced Re-Sequencer generates from all component streams
the single packet stream on a first-in-first-out packet basis. All duplicated/redundant packets
will be dropped. The number of component streams is not limited by the SureStream tech-
nology.
SureStream is a powerful algorithm that protects an IP link against packet losses and Loss of
Connection errors. The latter protection can be achieved only if the Codec device uses dual
IP ports for streaming out the component streams.
On a single IP port device, like the Stream-In and Stream-Out, SureStream cannot pro-
tect the IP link against Loss of Connection errors.
