Abstract
A Digital Subscriber Line Access Multiplexer (DSLAM) includes a Digital Subscriber Line interface unit for processing Physical Layer and Data Link Layer of the Digital Subscriber Line (DSL); at least two virtual DSLAM units adapted to simulate DSLAM to process a packet from the DSL interface unit; and a backhaul interface unit adapted to receive a packet processed by the DSLAM unit, and to send a packet from an access edge node or carrier equipment to the virtual DSLAM unit for processing. The disclosure further provides an Optical Network Unit, an Optical Line Terminal and a Base Station.
Claims22
A Digital Subscriber Line Access Multiplexer (DSLAM) comprising:
- at least two logic-independent virtual DSLAM units adapted to process a packet based on a respective pre-configured protocol;
- a Digital Subscriber Line interface unit connected with one or more Customer Premises Equipments (CPEs) via a Digital Subscriber Line (DSL) for processing Physical Layer and Data Link Layer of the DSL, and for sending a packet from the one or more CPEs to the corresponding virtual DSLAM unit;
- and
- a backhaul interface unit connected with one or more access edge nodes or carrier equipments via an Aggregation Network, for sending a packet processed by the virtual DSLAM unit to the access edge node or the carrier equipment corresponding to the virtual DSLAM unit.
An Optical Network Unit (ONU) comprising:
- at least two logic-independent virtual ONUs adapted to process a packet based on a respective pre-configured protocol;
- a user interface unit connected with one or more Customer Premises Equipments (CPEs) via a Digital Subscriber Line (DSL), an Ethernet Line or a Power Line Communication Line, for processing Physical Layer and Data Link Layer of the DSL, the Ethernet Line or the Power Line Communication Line, and for sending a packet from the one or more CPEs to the corresponding virtual ONU;
- and
- an Optical Distribution Node interface unit connected with one or more Optical Line Terminals (OLTs) via an Optical Distribution Node (ODN), for sending a packet processed by the virtual ONU to the OLT corresponding to the virtual ONU.
An Optical Line Terminal (OLT) comprising:
- at least two logic-independent virtual OLT units adapted to process a packet based on a respective pre-configured protocol;
- an Optical Distribution Node interface unit connected with one or more Optical Network Units (ONUs) or Optical Network Terminals (ONTs) via an Optical Distribution Node (ODN) for processing Physical Layer and Data Link Layer of a Passive Optical Network (PON), and for sending a packet from the one or more ONU/ONTs to the corresponding virtual OLT unit;
- and
- a backhaul interface unit connected with one or more access edge nodes or carrier equipments via an Aggregation Network, for sending a packet processed by the virtual OLT unit to the access edge node or the carrier equipment corresponding to the virtual OLT unit.
A Base Station (BS) comprising:
- at least two logic-independent virtual BS units adapted to process a packet based on a respective pre-configured protocol;
- an air interface unit connected with one or more Customer Premises Equipments (CPEs) or wireless terminals via a wireless air interface, for processing a wireless Physical Layer and a Data Link Layer, and for sending a packet from the one or more CPEs or wireless terminals to the corresponding virtual BS unit;
- and
- a backhaul interface unit connected with one or more access edge nodes or carrier equipments via an Aggregation Network, for sending a packet processed by the virtual BS unit to the access edge node or the carrier equipment corresponding to the virtual BS unit.
An Optical Access Network (OAN) comprising a Customer Premises Equipment (CPE), an edge node or carrier equipment, an Optical Network Unit (ONU), and an Optical Line Terminal (OLT);
- in particular, the ONU comprises:
- at least two logic-independent virtual ONUs adapted to process a packet based on a respective pre-configured protocol;
- a user interface unit connected with one or more Customer Premises Equipments (CPEs) via a Digital Subscriber Line (DSL), an Ethernet Line or a Power Line Communication Line, for processing Physical Layer and Data Link Layer of the DSL, the Ethernet Line or the Power Line Communication Line, and for sending a packet from the one or more CPEs to the corresponding virtual ONU;
- and
- a first Optical Distribution Node interface unit connected with one or more Optical Line Terminals (OLTs) via an Optical Distribution Node (ODN) for sending a packet processed by the virtual ONU to the OLT corresponding to the virtual ONU.
