  • Patent number: 11005683
    Abstract: Some embodiments provide a novel method for managing hardware forwarding elements (MHFEs) that facilitate the creation of multiple logical networks on a set of shared physical forwarding elements. The method uses a set of logical controllers that generate data that defines a set of logical networks, and a set physical controllers to distribute the generated data to the hardware forwarding elements. In some embodiments, each MHFE can serve as either a master MHFE or a slave MHFE for one set of computing end nodes (e.g., VMs, containers, etc.) in a logical network. To ensure proper routing of data packets to the computing end nodes, each MHFE sends to its physical controller an inventory (e.g., a table, a list, etc.) of the set of computing end nodes for which it serves as the master MHFE or the slave MHFE. Each physical controller forwards the inventory for each logical network to the logical controller for the logical network.

  • Patent number: 10993086
    Abstract: The present disclosure provides a method, a system, and an apparatus for transmitting group communication service data. In the present disclosure, the LTE uses a multimedia broadcast and multicast service (MBMS) to transmit group communication system enabler (GCSE) service data, a multi-cell/multicast coordination entity (MCE) knows whether a multimedia broadcast single frequency network (MBSFN) transmission mode or a single cell multicast transmission mode is used to transmit the GCSE service data. Whether the MBSFN transmission mode or the single cell multicast transmission mode is used to transmit the GCSE service data is determined based on UE capability information and UE location information. When the single cell multicast transmission mode is used, the MCE instructs an eNodeB (eNB) to use the single cell multicast transmission mode to transmit the GCSE service data.
