Abstract
Provided is an apparatus for matching Gigabit Ethernet (GbE) signals to an Optical Transport Hierarchy (OTH). The apparatus real-time records a source address and input port information of GbE Ethernet frames in a memory, compares a destination address of the Ethernet frame which is a payload of a GFP frame with memory table information, searches an output port location of the GbE, and interreceives GbE frames and Generic Frame Procedure (GFP) frames by multiplexing/demultiplexing.
Claims13
An apparatus for matching Gigabit Ethernet (GbE) signals with an Optical Transport Hierarchy (OTH), the apparatus comprising:
- a plurality of Gigabit Media Independent Interface (GMII) receiving units which respectively check errors in each of a plurality of GbE signals;
- a plurality of frame buffer units which output Ethernet frames of signals output from the GMII receiving units;
- an address learning and multiplexing unit which controls recording of a source address and port information included in each of the Ethernet frames output from the frame buffer units and multiplexes and outputs the Ethernet frames;
- a memory recording the source address and port information;
- a Generic Frame Procedure (GFP) sending and matching unit which matches the multiplexed Ethernet frames output from the address learning and multiplexing unit with a GFP-F frame format;
- and
- an Optical Channel Data Unit (ODU) sending and matching unit which outputs GFP-F frames output from the GFP sending and matching unit to an OTH network.
An apparatus for matching GbE signals to an OTH, comprising:
- a memory recording a source address and port information of each of Ethernet frames;
- an ODU receiving and matching unit which receives signals from an OTH network;
- a Generic Frame Procedure (GFP) receiving and matching unit which matches GFP-F frames output from the ODU receiving and matching unit with the Ethernet frames;
- an address lookup and demultiplexing unit which compares a destination address of the Ethernet frame with the source address recorded in the memory, and outputs demultiplexed Ethernet frames in response to the port information;
- and
- a plurality of Gigabit Media Independent Interface (GMII) sending unit which converts each of the Ethernet frames output from the address lookup and demultiplexing unit to a GMII format and outputs the GMII data.
