摘要： Disclosed is a mechanism that provides the extensions of PCEP message and the objects to support PCECC with P2MP capability in downloading the labels for branch node of P2MP TE LSPs. In one implementation, the present invention provides an apparatus, a system, a node and a method that receives a PCLabelUpd message with all the extensions and the objects to support PCECC with P2MP capability, detects the object and identifies that the label download is for P2MP TE LSP and for this LSP, the apparatus/ the system/the node acts as a branch node, and thereby the apparatus/ the system/the node downloads all the labels specified in the object to data plane with respect to any existing branch node download mechanism for a P2MP TE LSP.

摘要： Embodiments of the present invention provide a data backup method, applied to a storage system. The storage system includes a first storage device, a second storage device, and a backup storage device, a first logical unit LUN is constructed in the first storage device, a second logical unit LUN is constructed in the second storage device, and the first LUN and the second LUN are set to be in an active-active relationship. The method includes: when initiating a backup for the first LUN, sending a request message for searching for data consistency points to the second storage device to which the second LUN belongs, where the request message includes an IO data status record of the first LUN, and the IO data status record is used to record an IO that is delivered to a disk in the first LUN; receiving information about data consistency points that is obtained by the second storage device based on the IO data status record of the first LUN and an IO data status record, of the second LUN, that is stored in the second storage device; and creating a snapshot for the first LUN based on the data consistency points, and providing differential data between the current snapshot and a previous snapshot, where the differential data is written to a backup image that is created for the current backup in the backup storage device. Therefore, stored backup data is reduced.

摘要： The present invention discloses a data transmission acceleration method and a related apparatus and system. The method includes: sending, by a sending node, data packets to a receiving node at a specific rate, where each data packet carries a random sequence number and a scrolling sequence number related to a packet sending sequence; and quickly determining, by the receiving node, a lost data packet according to double sequence numbers of a received data packet, and feeding back sequence number information of the lost data packet to the sending node, so as to instruct the sending node to retransmit the lost data packet. The solutions of the present invention can improve a network throughput rate/transmission rate in a network with a high delay and a high packet loss rate, and the high throughput rate/transmission rate does not dramatically change because of some network jitter.

摘要： Embodiments of the present invention provide a control channel resource transmission method, a user equipment, and a base station, which relate to the communications field and can determine an antenna port according to a corresponding parameter, thereby ensuring that a user equipment correctly demodulates and receives a control channel or a control channel element sent by a base station. The control channel resource transmission method includes: obtaining, by a user equipment, a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter; determining an antenna port according to the obtained configuration parameter; receiving, by using the antenna port, a control channel or a control channel element sent by the base station; and determining, by the base station, the antenna port according to the same configuration parameter as that of the user equipment, and sending, by using the antenna port, the control channel or the control channel element to the user equipment. The embodiments of the present invention are applicable to control channel resource transmission.

摘要： The present invention discloses a video decoding method and a video decoder. The method includes: parsing coding tree split information to obtain a current node; determining, based on a depth N of the current node, a region covered by a current quantization group; obtaining a quantization parameter QP delta of a current coding unit CU in the region covered by the current quantization group; and obtaining a reconstructed picture of the current CU based on the QP delta of the current CU. By using the present invention, decoding efficiency can be improved.
