Abstract
For transmitting packets over radio communication links wherein flows of packets are delivered containing protected packets and unprotected packets, the status of propagation of the packets is verified in order to detect the presence of a faulty condition. If no faulty condition is detected, protected packet are transmitted over a first radio link wherein the transmission occupies a first portion of available bandwidth on the first radio link, and unprotected packets are transmitted on at least part of the remainder of the available bandwidth of the first radio link and at least part of available bandwidth the second radio link. If a faulty condition is detected, a protected packet is transmitted over the first radio link wherein the transmission occupies a first portion of available bandwidth on the first radio link, a duplicate of the protected packet is transmitted over the second radio link wherein said transmission occupies a second portion of available bandwidth on the second radio link, and unprotected packets are transmitted on at least part of the remainder of the available bandwidth of the first radio link and at least part of the remainder of the available bandwidth of t…
