NETWORK COMMUNICATION REDUNDANCY METHOD

摘要

There is provided an improved redundancy method for a communication network. The invention is based on the insight that a hitless failover can be performed by at the receiving node using a single common indexed play-out buffer in which a selective reconstruction of the transported data stream utilizing individual pieces, i.e. frames or packages, of a data stream received over multiple links is performed.

1. A method for node to node communication comprising:
providing each packet of a data stream to be transferredwith a respective identifier;
transporting over at least two links replicated data of said data stream from a transmitting node to a receiving node;at said receiving node:
receiving and buffering packets from said at least two links for subsequent forwarding of said data stream;wherein said identifier corresponds to a relative position of a packet in said data stream, and wherein said step of buffering comprisesreconstructing using received packets from at least one of said at least two links a predetermined portion of said data stream in a common indexed buffer.
