Optical Network and Node Using Timeslotted Reception

An optical network comprising:

• an optical core portion having a full mesh network configuration;
• and
• a plurality of nodes connected to the optical core portion, the plurality of nodes being divided into a plurality of groups, one group including up to m nodes,
• wherein each of the plurality of nodes
• is addressed by any node in a group to which a source node belongs only in a time slot associated with the group to which the source node belongs in a reception cycle period including a plurality of time slots,
• includes ASIC switches that switch and route an electrical signal corresponding to an optical signal received from the up to m nodes to a plurality of servers, and
• includes as the ASIC switches, a main switch that has switching capacity corresponding to average incoming traffic of the plurality of nodes, and operates in synchronization with the time slot, and
• an auxiliary switch that has switching capacity capable of processing traffic exceeding the average incoming traffic and operates regardless of the time slot.
