Method for allocating a point-to-point channel to a user module of an optical communication network, corresponding computer program product, storage medium and device

A method for allocating a point-to-point channel to a user module of an optical communication network, said network comprising user modules and optical terminations, and supporting point-to-multipoint channels and a plurality of point-to-point channels, one same point-to-point channel being assigned to one single optical termination, said method being implemented by an optical termination of said plurality, called available optical termination, and comprises:

• emitting a predetermined availability signal over the point-to-point channel assigned to said available optical termination, called available point-to-point channel, towards the user modules, wherein the predetermined availability signal comprises information belonging to the group consisting of:
• information representative of a reference number associated to the available point-to-point channel;
• information representative of a wavelength associated to the available point-to-point channel:
• information representative of a frequency associated to the available point-to-point channel;
• information representative of a modulation rate associated to the available point-to-point channel;
• and
• queuing a query for using the available point-to-point channel, originating from a user module, called requester user module.

A non-transitory computer-readable medium comprising program code instructions stored thereon which when executed by a processor configure the processor to implement a method for allocating a point-to-point channel to a user module of an optical communication network, said network comprising user modules and optical terminations, and supporting point-to-multipoint channels and a plurality of point-to-point channels, one same point-to-point channel being assigned to one single optical termination, said method being implemented for a user module called requester user module, and comprising:

• detecting a predetermined availability signal conveyed by a point-to-point channel of said plurality of point-to-point channels, and allocating the point-to-point channel over which said predetermined availability signal is conveyed, called available point-to-point channel, to said requester user module, wherein the detecting comprises verifying, on each point-to-point channel of said plurality of point-to-point channels, whether the predetermined availability signal is detected, and wherein the allocating comprises:
• in the case of a positive verification for one single point-to-point channel of said plurality, allocating said single point-to-point channel to said requester user module;
• in the case of a positive verification for a set of point-to-point channels of said plurality, allocating the point-to-point channel to said requester user module selected amongst said set of point-to-point channels, as function of a predetermined communication quality criterion.

A device for allocating a point-to-point channel to a user module of an optical communication network, said network comprising user modules and optical terminations, and supporting point-to-multipoint channels and a plurality of point-to-point channels, one same point-to-point channel being assigned to one single optical termination, said device comprising, for a user module called requester user module:

• a processor;
