Patent ID: 8707137

Claim:
A system for employing different bit-error-rate (BER) protection techniques for a plurality of communication sessions carried simultaneously over a communication link based on a quality of service level required by each particular individual session, the system comprising: an intermediate-adaptive-protection transmitter that is associated with a transmitting node at one side of the communication link and comprising a plurality of paths and each path is associated with a BER protection technique, the intermediate-adaptive-protection transmitter being configured to intercept a stream of a plurality of frames, with each of the plurality of frames being associated with one of the plurality of communication sessions, associate a BER protection technique for each frame of the plurality of frames according to a quality of service (QoS) level required by each frame, and transmit the frames subjected to the associated BER protection technique toward the other side of the communication link; an intermediate-adaptive-protection receiver associated with a receiving node on the other side of the communication link, the intermediate-adaptive-protection transmitter being configured to transmit the frames subject to the associated BER protection technique by being further configured to: convert the received plurality of frames into a stream of adapted-bit-error-rate segments by performing the associated BER protection technique on each frame; and transfer a stream of adapted-bit-error-rate segments toward the intermediate-adaptive-protection receiver; the intermediate-adaptive-protection receiver being configured to receive the adapted-bit-error-rate segments, process the adapted-bit-error-rate segments to restore the stream of the intercepted plurality of frames of the plurality of communication sessions, and transfer the restored stream of plurality of frames toward the receiving node; and wherein the number of bytes of the stream of adapted-bit-error-rate segments that is transferred toward the intermediate-adaptive-protection receiver is divided equally between the paths.
