Claim:
1. A method for efficient multilayer optical networking, the method comprising: receiving, by a first monitoring unit, traffic packets from a first packet generating device, each one of said traffic packets including an embedded virtual LAN (VLAN) tag indicating a destination of a second packet generating device; analyzing, by said first monitoring unit during a period of time, bytes content of said received tagged traffic packets and reporting a result of said analysis to a controller unit; receiving, by said controller unit, a plurality of different subcarriers to be used for sending said received tagged traffic packets to a corresponding destination; adding, by a tag unit, an embedded secondary virtual LAN (S-VLAN) tag to said analyzed tagged traffic packets, identifying based upon said corresponding destination to which subcarrier and to which sliceable bandwidth variable transponder in an optical network each tagged traffic packet is to be sent, said adding being based on a mapping procedure executed by a rule generator unit indicating which field of the received tagged traffic packets is to be matched, said matching procedure at least matching a last bit of the received tagged traffic packets with a rule programmed into said rule generator unit; sending said S-VLAN tagged traffic packets to a switch, the switch forwarding said S-VLAN tagged traffic packets to a given port of said identified sliceable bandwidth variable transponder; and sending, by said identified sliceable bandwidth variable transponder, said received tagged traffic packets via said plurality of different sub-carriers to a corresponding destination, said plurality of different sub-carriers following a same or different path, wherein said mapping procedure includes a feedback mechanism performed by a second monitoring unit analyzing traffic of said identified subcarriers during a period of time.
