| 20100223399 | METHOD AND APPARATUS FOR PROCESSING TIMESTAMP USING SIGNATURE INFORMATION ON PHYSICAL LAYER - A method and apparatus for processing a timestamp using signature information on a physical layer is provided. The timestamp processing terminal uses a pseudo-random binary sequence to assign signature information to a message which is to be sent to another terminal, and verifies the signature information on a physical layer. The signature information is used to identify the message as a sync message. Accordingly, it is possible to precisely process the timestamp. | 09-02-2010 |
| 20100287402 | TIMESTAMPING APPARATUS AND METHOD - A timestamping apparatus and method are provided. The timestamping apparatus implements timestamping on a synchronization message at a physical layer when the synchronization message is transmitted to the physical layer. At an application layer of the timestamping apparatus, a bit stream including a start indicator bit informing a start of a pseudo random number sequence, the pseudo random number sequence, and an end indicator bit informing an end of the pseudo random number sequence is generated to check whether or not a message received from the physical layer is the synchronization message, and is inserted as signature information of the synchronization message. At the physical layer of the timestamping apparatus, the signature information included in the synchronization message is detected, and timestamping information is generated when the signature information is detected. | 11-11-2010 |
| 20110044162 | METHOD OF FLUSHING FILTERING DATABASE IN ETHERNET RING NETWORK - A method in which a node of an Ethernet ring network flushes a filtering database includes operating a timer for delaying flushing of the filtering database when a topology of the ring network is changed, and flushing the filtering database when the timer is terminated. A method in which a node of an Ethernet ring network flushes a filtering database includes flushing the filtering database after receiving a protection switching frame that requests flushing of the filtering database, and forwarding a data frame in a queue state at a node and then forwarding the protection switching frame to an adjacent node. A method in which a node of an Ethernet ring network flushes a filtering database includes flushing the filtering database after receiving a protection switching frame that requests flushing of the filtering database, and deleting a data frame in a queue state at the node. | 02-24-2011 |
