摘要： With respect to first to 11th DSL subscriber line termination units (112-1 to 112-11) each terminating subscriber lines for a plurality of channels on a board, there is provided an auxiliary DSL subscriber line termination unit (112-12) terminating the same number of subscriber lines on a board. Upon occurrence of failure corresponding to any of the channels, a redundant control panel (114) implements switching to a corresponding channel of the auxiliary DSL subscriber line termination unit. By this switching, a physical interface number of a packet is changed. However, it can be dealt with by conversion to the same logical interface number as before using a mapping table (212) under the control of a protection control section (215).

摘要： Some embodiments provide a method for forwarding multicast data messages at a forwarding element on a host computer. The method receives a multicast data message from a routing element executing on the host computer along with metadata appended to the multicast data message by the routing element. Based on a destination address of the multicast data message, the method identifies a set of recipient ports for a multicast group with which the multicast data message is associated. For each recipient port, the method uses the metadata appended to the multicast data message by the routing element to determine whether to deliver a copy of the multicast data message to the recipient port.

摘要： Techniques for managing the distribution of configuration information that supports the flow of packets in a cloud environment are described. In an example, a virtual network interface card (VNIC) hosted on a network virtualization device NVD receives a first packet from a compute instance associated with the VNIC. The VNIC determines that flow information to send the first packet on a virtual network is unavailable from a memory of the NVD. The VNIC sends, via the NVD, the first packet to a network interface service, where the network interface service maintains configuration information to send packets on the substrate network and is configured to send the first packet on the substrate network based on the configuration information. The NVD receives the flow information from the network interface service, where the flow information is a subset of the configuration information. The NVD stores the flow information in the memory.

摘要： The present disclosure discloses an FPGA device for implementing a network-on-chip transmission bandwidth expansion function, and relates to the technical field of FPGAs. When a predefined functional module with built-in hardcore IP nodes is integrated in an FPGA bare die, soft-core IP nodes are configured and formed by using logical resource modules in the FPGA bare die and are connected to the hardcore IP nodes to form an NOC network structure, so as to increase nodes and expand the transmission bandwidth of the predefined functional module. On the other hand, the soft-core IP nodes can be additionally connected to input and output signals in the predefined functional module and also can expand the transmission bandwidth of the predefined functional module.
