20090175166 | METHOD, APPARATUS AND SYSTEM FOR RING PROTECTION - A method, apparatus and system for Ethernet Ring Protection (ERP) are disclosed. The system includes: a node which detects a link fault blocks the port connected with the faulty link after the link on the ring is faulty, and sends a fault alarm message to adjacent nodes; and the adjacent nodes judge whether the state of the node changes from the normal state to the faulty state according to the received fault alarm message, and clear the forwarding table of the node if such is the case. | 07-09-2009 |
20090185482 | METHOD AND SYSTEM FOR PROTECTION SWITCHING DECISION - A method for protection switching decision includes: performing performance monitoring and failure detection on a first transmitting entity that transmits services; performing performance monitoring and failure detection on a second transmitting entity that does not transmit services; and making protection switching decision according to the performance monitoring and failure detection results of the first transmitting entity and second transmitting entity. A system for performance monitoring is also disclosed. In embodiments of the present invention, performance monitoring may be performed on the transmitting entity that does not transmit services, thus avoiding invalid switching of services and improving the quality of services. | 07-23-2009 |
20100278040 | PROTECTION METHOD, SYSTEM, AND DEVICE IN PACKET TRANSPORT NETWORK - A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path. | 11-04-2010 |
20110019538 | FAILURE RECOVERY METHOD IN NON REVERTIVE MODE OF ETHERNET RING NETWORK - Provided is a failure recovery method in a non-revertive mode of an Ethernet ring network. In an Ethernet ring network, link priorities between nodes or node priorities are determined based on media access control (MAC) addresses and the nodes having blocked ports are determined after failures are recovered from based on the priorities so that the blocked ports can be distributed. | 01-27-2011 |
20110038258 | METHOD AND SYSTEM FOR SERVICE PROTECTION - A method for service protection is disclosed, which is applied to a 1:n switching technique. The method includes the following steps. A source end sends a service to a work transmission entity, the work transmission entity performs performance monitoring through the transmitted service, a sink end receives the service from the work transmission entity; when a Signal Degrade (SD) fault occurs at the work transmission entity, the source end sends the service to the work transmission entity and a protection transmission entity simultaneously, and the sink end selects to receive the service from the protection transmission entity; the protection transmission entity performs the performance monitoring through the transmitted service; when the SD fault occurs at both the work transmission entity and the protection transmission entity, the sink end still receives the service from the protection transmission entity. A system for service protection is also disclosed. Technical solutions enable the service to get valid protection during the transmission process, and avoid frequent switching of the service, thereby improving the service quality. | 02-17-2011 |
20110292789 | METHOD, APPARATUS AND SYSTEM FOR RING PROTECTION - A method, apparatus and system for Ethernet Ring Protection (ERP) are disclosed. The method includes: detecting, by a node, a link fault on a ring; blocking, by the node, a port connected with the faulty link after detecting the link fault, and sending a fault alarm message to other nodes on the ring, wherein the fault alarm message contains a fault identifier; and judging, by a node which receives the fault alarm message, whether the fault identifier changes; if the fault identifier changes, the node which receives the fault alarm message storing the fault identifier contained in the fault alarm message and clearing a forwarding table of the node which receives the fault alarm message. | 12-01-2011 |
