Enhanced reliability routing protocol

A method of enhanced reliability routing within a system comprising one or more networks including several nodes connected together by communication means, said system having a transmission network access (TNA) charged with transmitting on a physical medium, data to a next network interconnection node (NIN), said system using a link-state routing protocol for constructing a global topology of the nodes within the system, wherein said method of enhanced reliability routing determines a logical topology of network interconnection nodes (NINs) by the following steps:

• discovering a neighbourhood using a Module NIN_TOPO_01 as a Neighbourhood Discovery Module by virtue of intrinsic functions of the one or more networks;
• smoothing a neighbourhood using a Smoothing Module:
• NIN13 TOPO_02 using information provided by the TNA to improve stability of the link-state routing protocol;
• distributing the neighbourhood to the NINs using a Distribution Module NIN_TOPO_03;
• relaying of the information associated with a node including neighbours, links and their characteristics denoted as Sig_Neighbourhoods by a subset of the NIN nodes being a relay of Sig_Neighbourhoods using a Relay Module NIN_TOPO_04;
• enhancing hop by hop a reliability of a transmission of the Sig_Neighbourhoods between the various nodes using an Enhancement Module NIN_TOPO_05;
• transmitting the Sig_Neighbourhoods in a point-to-multipoint mode using a Transmission Module NIN_TOPO_06;
• announcing oriented characteristics of logical links in the logical topology solely by source routers of the logical links using an Announcement Module NIN_TOPO_07;
• marking of signalling data so as to manage non-sequencing in reception associated with the transmitting using a Marking Module NIN_TOPO_08;
• and
• calculating the global topology using a Calculation Module NIN_TOPO_09.
