Traffic packet duplication

You can enable traffic packet duplication to prevent loss when transmitting traffic packets through the following transport services:

If traffic packet duplication is enabled for a transport service, the source CPE device duplicates traffic packets and sends them through all connections. The destination CPE device receives the traffic packets and drops superfluous traffic packets. If a traffic packet sent trough a connection becomes lost, the destination CPE device can receive that traffic packet through a different connection. Duplicating traffic packets can be used for applications that are in high demand, such as ATMs and POS terminals.

To enable traffic packet duplication, select Broadcast in the Balancing mode drop-down list when creating or editing a transport service.

For example, the figure below shows a CPE device with the gateway role in a data center; this CPE device uses two connections to send traffic packets to a standard CPE device at a remote location. The standard CPE device at the remote location then relays the traffic packets to end users. Both CPE devices are added to a transport service that has traffic packet duplication enabled, which means that traffic packets are duplicated and transmitted simultaneously through two connections.
