Publication number: 20230148392Abstract: This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities.Type: ApplicationFiled: December 30, 2022Publication date: May 11, 2023Inventors: Bin Yu, Wenjun Chang, Xingjian He, Wei Chen, Donghui Wang

Publication number: 20230138768Abstract: A network configuration method, an apparatus, and a computer-readable storage medium are provided, and belong to the field of communication technologies. The method includes: A first execution device sends a device discovery message to a management device. The device discovery message is a layer 2 packet and includes a first port identifier, where a port identified by the first port identifier is a port, in an up state, of the first execution device (301). The first execution device receives a first configuration message from the management device. The first configuration message is a layer 2 packet and includes a configuration parameter for a second execution device. The configuration parameter includes an internet protocol address of the second execution device, and the second execution device is connected to the port identified by the first port identifier (303). The first execution device sends the first configuration message through the port identified by the first port identifier (302).Type: ApplicationFiled: December 30, 2022Publication date: May 4, 2023Inventors: Bin Yu, Wenjun Chang, Zhihong Lin, Hanyu Wei

Patent number: 11133998Abstract: A method, an apparatus, and a system for measuring a network delay are disclosed. The method includes: acquiring delay measurement information obtained by measuring a service flow by at least one target logical port TLP, where the delay measurement information includes: timestamp information, a service flow identifier, and a TLP identifier; and transmitting the delay measurement information to a measurement control point MCP, so that the MCP determines details about a network delay according to the timestamp information, the service flow identifier, and the TLP identifier. Embodiments of the present application further provide an apparatus and a system for measuring a network delay. Embodiments of the present application achieve direct and accurate delay measurement of a service flow in scenarios of point to point transmission or point to multipoint transmission on the network, and reflect details about a real delay of the service flow.Type: GrantFiled: July 29, 2019Date of Patent: September 28, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Wei Fang, Hongming Liu, Wenjun Chang

Patent number: 9386762Abstract: Provided is a renal sarcomatoid cell line RCC09HYF, of which the deposit No. is CCTCC C201130, and the preparation method of the renal sarcomatoid cell line. The renal sarcomatoid cell line RCC09HYF can grow for a long period and be steadily passaged in vitro. By tumorigenic experiments using in-situ animal models in vitro it has been found that: the tumorigenesis is relatively fast inside animals and 3-4 weeks after tumor inoculation, the transplanted tumors fill the whole abdominal cavity, and dyscrasia appears in above 50% of nude mice; moreover, lung metastasis is present in a few individuals. The renal sarcomatoid cell line RCC09HYF can provide an effective and steady cell model for further study of the genesis and metastasis mechanism of renal sarcomatoid carcinoma in persons of Han nationality and for clinical prediction, diagnosis and treatment.Type: GrantFiled: July 19, 2012Date of Patent: July 12, 2016Assignee: SECOND MILITARY MEDICAL UNIVERSITYInventors: Xiaojie Tan, Yifang Han, Wei Guan, Wenjun Chang, Guangwen Cao
