Patent number: 12224939Abstract: This application discloses a service packet forwarding method and related apparatus. In the service packet forwarding method, when receiving a packet sent by any second virtual resource module connected to a first service function forwarder (SFF), the first SFF dynamically determines a forwarding path of the packet based on configuration information of a second virtual resource module for implementing a second service function, to achieve dynamic load balancing on the packet instead of relying on a service function chain ingress node to perform load balancing, so as to reduce pressure on the service function chain ingress node.Type: GrantFiled: April 28, 2022Date of Patent: February 11, 2025Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Fang Wang, Jianbin Xu, Tao Bai, Yongkang Zhang

Patent number: 10197793Abstract: A light modulator (e.g., for terahertz radiation) may be constructed using a prism in which light undergoes total internal reflection (TIR) at one surface. A tunable conductive layer is disposed on the TIR surface. The tunable conductive layer can have a conductivity that is dynamically controllable, e.g., by applying a voltage across the tunable conductive layer or by optically pumping the tunable conductive layer. The tunable conductive layer can absorb a portion of the reflected light beam, attenuating the beam, with the attenuation being a function of the electrical conductivity of the tunable conductive layer. The phase of the reflected light beam can also be altered as a function of electrical conductivity of the tunable conductive layer.Type: GrantFiled: May 8, 2017Date of Patent: February 5, 2019Assignee: The Chinese University of Hong KongInventors: Xudong Liu, Zefeng Chen, Edward Philip John Parrott, Benjamin Ung, Jianbin Xu, Emma MacPherson
