Abstract: A method and device for forwarding a packet are disclosed. When a first access device connected with a database server is to be configured with a mirror image rule, an SDN controller can transmit a mirror image rule adding message carrying the mirror image rule to the first access device. Where, the mirror image rule comprises an IP address of the database server, a MAC address of a database audit device connected with a second access device and a VXLAN tunnel between the first access device and the second access device. When receiving a database access packet whose destination IP address is an IP address of the database server, the first access device may replace a destination MAC address of a mirror packet for the database access packet with a MAC address of the database audit device according to the mirror image rule and forward the encapsulated VXLAN packet.

Abstract: Disclosed is a method of loading a signature rule and a network device thereof. According to an example of the method, the network device may first receive a signature rule library sent by a cloud server, wherein the signature rule library contains one or more signature rules, each of which is associated with corresponding device type configuration information. The network device may determine for each signature rule whether device type configuration information associated with the signature rule matches local device type configuration information of the network device. If the device type configuration information associated with the signature rule matches the local device type configuration information of the network device, the network device may load the signature rule.

Abstract: In this example, a method and an AP for positioning a terminal are provided. And wherein, when receiving a probe request sent by a terminal, the AP determines whether the terminal is a non-associated terminal or not according to acquired terminal status information. When determining the terminal as a non-associated terminal, the AP may measure round trip time (RTT) for the terminal. The AP may send the measurement result to a server, so that the server may position the terminal according to the measurement result.

Abstract: A router has a shape graph that is a compressed form of a trie that represents routing information for routing data packets in a network, and an update data structure that includes plural entries corresponding to nodes of the shape graph, the plural entries containing count values indicating respective numbers of nodes of the tie represented by the corresponding nodes of the shape graph. The router incrementally updates the shape graph as a portion of the routing information changes, where the incremental updating uses information in the update data structure.

Abstract: An adaptive ambulatory support includes a shock absorbing and pivoting tip assembly attached to the staff of a walking aid, such as a cane, crutch or walker. The shock absorbing and pivoting tip assembly includes a shock absorber sandwiched between a lower portion and an upper portion. The shock absorber may be a bendable spring or elastic material. The tip assembly enables the shaft of the walking aid to dynamically pivot without the loss of adherence of the lower portion to the floor surface and simultaneous provides the adaptive shock absorbing capability in any angle during ambulation.

Abstract: A portable unibody living facility is provided that includes a living unit attached to a trailer. The living unit may be connected to a host house via a connector through which electrical and plumbing connections may be made. The living unit is accessible and includes an accessible shower area, a bedroom area, and a hoist track system integrated into the ceiling and running from the bedroom area to the shower area.

Abstract: A control device may manage a switch device within a same software defined network (SDN) of the control device, manage a topology structure of an SDN corresponding to the SDN instance managed by the control device, and calculate flow paths based on the topology structure.

Abstract: A network access device may obtain user fingerprint information of a terminal. The network access device may transmit the user fingerprint information of the terminal to a portal server, before the terminal is authenticated, so that the portal server may push to the terminal an authentication page corresponding to the user fingerprint information of the terminal.

Abstract: According to an example, an Edge Virtual Bridging (EVB) station is configured with a VM, an ER and multiple physical network cards. The VM is configured with multiple virtual network cards and each virtual network card has one VSI. Each VSI is connected with one of the physical network cards via the ER. One of the physical network cards is configured as a primary physical network card, and another is configured as a secondary physical network card. A VSI corresponding to the primary physical network card is configured as a primary virtual interface, and a VSI corresponding to the secondary physical network card is configured as a secondary virtual interface. After determining the primary physical network card failed, the secondary physical network card is configured as a new primary physical network card, and the secondary virtual is configured as a new primary virtual interface.

Abstract: According to an example, after a primary port of a primary switch and a secondary port of a secondary switch are connected to each other and the primary port is configured to operate in a fabric mode, the primary switch may send a mode switch request packet to the secondary switch through the primary port. The secondary switch may change the secondary port from operating in an Ethernet mode to the fabric mode based on information contained in the mode switch request packet and may send a mode switch response packet to the primary switch.

Abstract: An access device receives a neighbor discovery protocol (NDP) packet sent from a user equipment (UE). The access device parses the NDP packet to obtain equipment information of the UE carried by the NDP packet. The access device transmits reporting message to a management server, wherein the reporting message carries the equipment information of the UE. Upon receiving a notification for identity authentication of the UE from the management server, the access device initiates an identity authentication invitation to the UE. The access device submits identity authentication information of the UE to the management server for authentication. The access device stores a first access control entry for the UE issued by the management server in its own data plane to control the UE's access to network resources after the identity authentication of the UE is permitted.

Abstract: According to an example, in a method and an apparatus for expanding member ports of a link aggregation group between clusters, each apparatus in a cluster receives a port joining link aggregation group message sent by a master control board on a master apparatus in the cluster.
