Abstract: Disclosed are a method and apparatus for sending a segment routing traffic engineering (SR-TE) policy, a method and apparatus for receiving an SR-TE policy, a network element, and a computer-readable storage medium. The method for sending an SR-TE policy includes creating an SR-TE policy instance by a first network element; and sending an SR-TE policy corresponding to the SR-TE policy instance to a second network element by the first network element, where the SR-TE policy carries path identifier information and primary/standby state information of a segment list so as to support fast reroute (FRR) of a segment list level.

Abstract: A concealed integrated device of corner laser radars comprising a cover plate, a fixed support, a lifting structure, an ejection structure, laser radars and a controller, wherein the cover plate is located on a fender of a vehicle body and matches an opening in the fender in terms of size; the fixed support, the lifting structure, the ejection structure, the laser radars and the controller are all located inside the fender; the lifting structure is arranged on the fixed support and is connected to the cover plate; the laser radars are arranged on the ejection structure; and the ejection structure is arranged on the fixed support.

Abstract: Disclosed is a data processing method and system, an encapsulation node, and a deencapsulation node. The data processing method comprises: obtaining at least two sets of data to be sent, wherein the data comprises prefix data and suffix data; obtaining public prefix data from the prefix data; obtaining a local index based on the public prefix data, and writing the local index and the public prefix data into a preset prefix table; writing the suffix data and the local index into a preset suffix table; and writing the data in the prefix table and the data in the suffix table into a preset data encapsulation table, and sending the data encapsulation table.

Abstract: Provided are an interior gateway protocol flooding optimization method and device, and a storage medium. The method for optimizing flooding of an internal gateway protocol comprises: flooding, by a first node, a first packet carrying link state data and first record information to at least one neighboring node, wherein the first record information comprises indication information of nodes that the link state data has passed through. In this embodiment, by carrying indication information of a node that link state data passes through, it is convenient for the node to reduce redundant sending of link state information according to the information, thereby accelerating convergence speed.

Abstract: There is provided a method of facilitating distributed data search in a federated cloud. The method includes generating, at a computing cloud of the federated cloud, a search tree structure for indexing a data set in the computing cloud; mapping a selected set of nodes of the search tree structure to respective peer nodes of a peer-to-peer tree structure spanning a plurality of servers in a plurality of computing clouds of the federated cloud, the peer-to-peer tree structure configured for routing a query for searching a data item in the federated cloud; and informing, for each selected node, the plurality of types of attribute conditions associated with the selected node to the corresponding mapped peer node such that the corresponding mapped peer node has associated therewith the plurality of types of attribute conditions.
