Publication number: 20170195282Abstract: Embodiments of the present application disclose an address processing method. An address allocation device allocates, according to an address allocation request of a service node, a target address block in an idle state in a global address pool to the service node, and sets the target address block to an occupied state. The service node updates a local address pool according to the allocated target address block, and performs address allocation or release for user equipment based on the updated local address pool. When a preset recycling trigger condition is met, the address allocation device obtains recycling information reported by the service node, determines, according to the recycling information, an address block that is in the global address pool and corresponding to the recycling address block.Type: ApplicationFiled: March 20, 2017Publication date: July 6, 2017Inventor: Xindong Teng

Patent number: 9514209Abstract: Embodiments of the present invention provide a data processing method and a data processing device. If to-be-compressed data includes a data fragment that is the same as a first half of a variable block in a duplicate database and is different from a second half of the variable block, a new variable block with granularity smaller than that of the matching variable block can be generated, and the new variable block is added to the duplicate database. The granularity of the new variable block is smaller, which increases the probability of subsequent to-be-compressed data matching the updated duplicate database, thereby improving compression efficiency.Type: GrantFiled: February 21, 2014Date of Patent: December 6, 2016Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Xindong Teng
