摘要： An access point (AP) for an indoor antenna distributed deployment environment provides an access service for a wireless terminal. The AP includes N radio frequency (RF) processing units and NWM RF switches (RFSs). Each RFS includes a public port and at least two branch ports. The at least two branch ports respectively connect with at least two antennas deployed in different indoor areas via RF feeders. The RF processing unit includes M RF chains. Each RF chain is connected to a public port of an RFS. The RF processing unit is to transmit a packet to the wireless terminal, based on a predetermined antenna combination for the wireless terminal.

摘要： A first edge node in a first site network receives an Internet Protocol (IP) address resolving request packet from a device in the first site network. The first edge node replaces a source Media Access Control (MAC) address of an Ethernet frame header and a sender MAC address in a packet body of the IP address resolving request packet with the MAC address of the first edge node. The first edge node forwards the IP address resolving request packet to a second site network via a tunnel linking the first site network and the second site network.

摘要： An access point (AP), deployed at a user network side, identifies a type of a packet received from a wireless client at the user network sid and performs a tunnel encapsulation on the packet if the packet is a Dynamic Host Configuration Protocol (DHCP) request packet to generate a tunnel encapsulated DHCP request packet. The AP sends the tunnel encapsulated DHCP request packet to an access controller (AC) deployed at a cloud platform side. The AP performs a tunnel de-capsulation on a DHCP response packet returned from the AC to generate a tunnel de-capsulated DHCP response packet, and sends the tunnel de-capsulated DHCP response packet to the wireless client. The tunnel de-capsulated DHCP response packet is loaded with address information allocated by the AC.

摘要： In a method for forwarding a packet, a physical forwarding unit receives a data packet, may find a first subnet route based on a destination IP address of the data packet, and forwards the data packet to a virtual forwarding unit via an output interface of the first subnet route. The virtual forwarding unit receives the data packet may find a first host route based on the destination IP address of the data packet, and forwards the data packet based on the first host route.

摘要： Before restarting an IS-IS protocol process, the first device sends an IIH packet with a RR flag set and a hold time field being a first predetermined value to a second device. The first predetermined value is greater than a normal value of a hold time kept in the second device for the first device, and the first device establishes an adjacency with the second device. After receiving an IIH packet with a RA flag replied by the second device, the first device restarts the IS-IS protocol process and starts to execute a GR process. The IIH packet with the RA flag set is replied by the second device after the second device updates the hold time kept in the second device for the first device according to the first predetermined value.

摘要： A method for transmitting a packet is disclosed. An intermediate device in a network may acquire, after receiving a service packet of a target service from a server in the network, a guaranteed bandwidth of the target service corresponding to service information of the target service according to the service information carried in the service packet. Then the intermediate device may transmit the service packet of the target service according to the guaranteed bandwidth.

摘要： A CB device receives a first packet sent from another device through a stacking port. In response to determining, based on source port information carried in the first packet, that the first packet entered the stacking system from a PE device and the first packet is a non-unicast packet, the switch module performs mirroring processing to the first packet to obtain a mirrored packet, and transmits the first packet and the mirrored packet to a packet buffering module of the CB device. In response to determining that a second packet from the packet buffering module entered the stacking system from the PE device and the second packet is the non-unicast packet, the second packet is forbidden from being forwarded through a first-level stacking port of the CB device.

摘要： According to an example, when transmitting MAC forwarding table items to other BEB devices in an SPBM network for synchronization, a BEB device aggregates a plurality of MAC forwarding table items in a MAC forwarding table belonging to a same MAC segment into an aggregated MAC forwarding item, and transmits the aggregated MAC forwarding table item to the other BEB devices.

摘要： A forwarding path link table packet is generated, the forwarding path link table packet comprises forwarding information of each SDN switch on a forwarding path; and the forwarding path link table packet is delivered to any one of SDN switches on the forwarding path, to enable the forwarding path link table packet to be delivered among SDN switches on the forwarding path, so as to cause each SDN switch that receives the forwarding path link table packet to generate a forwarding flow table entry of the SDN switch according to the forwarding information of the SDN switch in the forwarding path link table packet, and forward the forwarding path link table packet on the forwarding path.

摘要： A SDN controller receives a packet sent by a VTEP to be forwarded at the layer-3. The SDN controller may determine at least one VXLAN gateway that could reach the destination node of the packet and which is located in the same VXLAN with a source node of the packet, as a forwarding gateway. After forwarding gateway is determined, the SDN controller may distribute a flow entry to the VTEP, which may help VTEP to forward the packets sent from the source node to the destination node to the determined forwarding gateway.
