Title (EN) METHOD FOR TRANSMITTING LCAS PROTOCOL VIA AN OPTICAL COMMUNICATION LINE
(FR) PROCEDE DE TRANSMISSION DE PROTOCOLE LCAS VIA UNE LIGNE DE COMMUNICATION OPTIQUE
Abstract:
(EN) A technique for exchanging LCAS control information between a first network element and a second network element interconnected by a bi-directional optical communication line, while conveying substantially unidirectional data traffic in the form of a virtual concatenated group (VCG) binary stream transmitted in a first direction via the bi-directional optical communication line, the technique comprising: - in the first direction, transmitting the LCAS control information via the bi-directional optical communication line in the VCG binary stream, by placing the information in one or more overhead bytes conventionally specified for the VCG binary stream, - in a second (opposite) direction, transmitting the LCAS control information in an existing binary stream non-related to the above-mentioned unidirectional data traffic; the existing binary stream should pass via a communication trail connecting the first network element and the second network element but not obligatory coinciding with the above-mentioned line; the discussed information should be placed in one or more overhead bytes of the existing binary stream.
(FR) L'invention concerne une technique d'échange d'informations de commande LCAS entre un premier élément de réseau et un second élément de réseau interconnectés par une ligne de communication optique bidirectionnelle, tout en transportant un trafic de données sensiblement unidirectionnel sous forme de flux binaire de groupe concaténé virtuel (VCG) transmis dans une première direction via la ligne de communication optique bidirectionnel, la technique consistant: - dans la première direction, à transmettre des informations de commande LCAS via la ligne de communication optique bidirectionnelle dans le flux binaire VCG, par placement des informations dans des octets de surdébit habituellement spécifiés pour le flux binaire VCG, - dans une seconde direction (opposée), à transmettre des informations de commande LCAS dans un flux binaire existant non associé au trafic de données unidirectionnel mentionné ci-dessus; le flux binaire existant devrait passer à travers un rail de communication reliant le premier élément de réseau et le second élément de réseau, mais ne coïncide pas obligatoirement avec la ligne susmentionnée; les informations traitées devraient être placées dans un ou plusieurs octets de surdébit du flux binaire existant.
