20080259808 | METHOD FOR DETECTING AN AVAILABLE/UNAVAILABLE STATE OF PACKET TRANSPORT NETWORK - A method for detecting an available/unavailable state of a packet transport network, includes the steps of: in the packet transport network, detecting a severely errored second (SES) using performance parameters of the packet transport network, and detecting an available/unavailable time with the SES as a reference, and thus providing a method of determining if the packet transport network enters and exits the available/unavailable state. In this way, the detection of the available time of the packet transport network is achieved, and it is ensured that performance parameters of the packet transport network are measured when the packet transport network is in an available state, while the measurement of the performance parameters of the packet transport network is stopped when the packet transport network is in an unavailable state. Thus, the OAM mechanism of the packet transport network can be improved, and the defects in the performance management of the packet transport network can be eliminated. | 10-23-2008 |
20090168646 | METHOD, APPARATUS AND SYSTEM FOR AVOIDING LOOP IN ETHERNET RING - A method for avoiding loop in an Ethernet ring includes, preventing, by transmit nodes constituting a ring, themselves from using the data frame transmission capabilities of ports on a link affected by a failure, when the ring failure has been detected by a transmit node constituting a ring; obtaining, by a master node of the ring, the ring failure, and performing a protection switching operation; flushing, by transmit nodes, their own forwarding tables, and forwarding a frame according to the flushed forwarding tables. If the failure in the ring has been removed, the master node shifts to a normal state and transmit nodes restore their data frame transmission capabilities of ports on a link ever affected by a failure. A system and an apparatus for avoiding data loop in an Ethernet ring are also disclosed. | 07-02-2009 |
20100039939 | METHOD AND SYSTEM FOR OBTAINING PATH INFORMATION, PATH COMPUTATION ELEMENT - A method and a system for obtaining path information as well as a PCE are disclosed herein. All the PCEs from the source PCE to the confluent PCE compute the shortest path from the source node to the egress border node of the domain covered by the respective PCE one by one, and send the computation result to the next-hop PCE until the confluent PCE. Meanwhile, all the PCEs from the destination PCE to the confluent PCE compute the shortest path from the destination node to the ingress border node of the domain covered by the respective PCE one by one, and send the computation result to the previous-hop PCE until the confluent PCE. After receiving computation results from the previous-hop PCE and the next-hop PCE, the confluent PCE computes the shortest path between the source node and the destination node, and sends the shortest path to the source PCE. | 02-18-2010 |
20120066368 | METHOD AND APPARATUS FOR ABSTRACTING LOGICAL TOPOLOGY INFORMATION OF PEER-TO-PEER NETWORK - The present invention provides a method and an apparatus for abstracting logical topology information of a Peer-to-Peer (P2P) network. The method includes: obtaining a set of Points of Presence (POPs) of peer clients in the P2P network; using a relevant algorithm of a routing protocol to calculate a best path between any two POPs in the set of POPs and a weight value of the best path; and collecting calculation results of the best path and the weight value that are obtained on each POP to obtain a set of abstract logical topology records of the P2P network. The embodiments of the present invention provide a universal and efficient method for abstracting logical topology information, which greatly reduces network topology information that needs to be transmitted, mitigates a risk of exposing lower-layer network topology information, and transmits the network topology information to a P2P application server securely and concisely. | 03-15-2012 |

20140160935 | METHOD, APPARATUS AND SYSTEM FOR PACKET REASSEMBLY AND REORDERING - A method for packet reassembly and reordering, comprising: receiving a cell sent by a source port, wherein the cell carries a Source Identification (SID), a packet sequence number and a cell sequence number; preprocessing the received cell according to the SID to determine whether the cell shall be inserted into a packet reassembly database; ordering cells in the packet reassembly database according to the packet sequence number to obtain a correctly ordered packet; if the correctly ordered packet is a complete packet, ordering the cells of the correctly ordered packet according to the cell sequence number to obtain correctly ordered cells; and performing a packet reassembly for the correctly ordered cells. Correspondingly, a network device and a communication system are provided. | 06-12-2014 |
20150029988 | METHOD, DEVICE AND SYSTEM FOR UPLINK RESOURCE ALLOCATION - The present disclosure discloses a method, a device and a system for uplink resource allocation, relating to a wireless communication field and used for further reducing interference of service transmission between cell uplinks. The method for uplink resource allocation includes: a first base station determines uplink almost blank subframe (UL ABS) subframe(s) unused currently of a user equipment (UE) served by the first base station; and the first base station sends information of the determined UL ABS subframe(s) unused currently of the UE served by the first base station to a second base station, so that the second base station acquires available UL ABS subframe(s) and takes the available UL ABS subframe(s) as uplink subframe resource(s) of the second base station. The present disclosure is applied to a resource allocation scenario. | 01-29-2015 |
20150033326 | System and Method for Unlocking Screen - Disclosed are a method for unlocking a screen and a system for installing a screen. It is determined whether to unlock the screen by calculating an angle between a starting position and a current position of a touch point on the screen with the unlocking reference point as a vertex of the angle. With a technical solution of the disclosure, no path or destination position for screen unlocking is defined, with more casual operation, enhanced user experience, and simpler setting, thereby facilitating usage. Moreover, unlocking by mistake can also be prevented by the setting. | 01-29-2015 |
