摘要： The present disclosure relates to a traffic routing method and a traffic routing device. A member device of a stacking system receives traffic destined for a destination node. If there is at least one valid Equal-cost multi-path (ECMP) associated with an address of the destination node in a forwarding table, the member device routes the received traffic to the destination node through the at least one valid ECMP path. Otherwise, the member device selects at least one other member device of the stacking system for routing the received traffic, updates an ECMP path associated with the address of the destination node in the forwarding table to a stacking link connecting the member device with the selected at least one member device, and transmits the received traffic to the selected at least one member device.

摘要： When a User Edge Device (UED) receives a unicast packet from a user side, the UED searches in a Media Access Control (MAC) table. When a matching entry in the MAC table is found, the UED forwards the unicast packet locally. When no matching entry in the MAC table is found, the UED transmits the unicast packet to a Network Edge Device (NED). When the UED receives a broadcast packet from the user side, the UED broadcasts the broadcast packet within a same Virtual Local Area Network (VLAN) of a local site and forwards to the NED.

摘要： A control plane of a logical network device creates a service link aggregation group and adds one port from each member network device to the service link aggregation group. The logical network device includes member network devices and each port connects the logical network device to the same neighbor device. When a port of the logical network device receives a message with an unknown source address, the control plane determines if the receiving port is in any service link aggregation group. After determining the receiving port is in the service link aggregation group, the control plane configures a data plane of the logical network device with mappings between the address and the ports in the service link aggregation group.

摘要： The present disclosure describes data transmission in a packet transport network (PTN). A multiple stack device facilitates data transmission between a first edge device of a first PTN technology and a second edge device of a second PTN technology. After receiving a first packet of the first PTN technology from the first edge device, the multiple stack device identifies a first connection with the first edge device according to information of the first packet and identifies a second connection with the second edge device from the first connection based on a relationship between the first connection and the second connection. The first packet is de-encapsulated and re-encapsulated into a second packet of the second PTN technology according to the second connection. The second packet is then forwarded to the second edge device via the second connection.

摘要： The present disclosure describes traffic forwarding in a network where Virtual Local Area Networks (VLANs) are deployed over geographically dispersed sites. The network comprises a first edge device (ED) at a first site and a second ED at a second site. In one example, the first ED receives traffic from a host device within the first site. The received traffic is to be forwarded to the second ED via a virtual link established between the first ED and second ED. The first ED determines whether a bandwidth required by the received traffic exceeds a bandwidth threshold negotiated between the first ED and second ED for the first ED to forward traffic to the second ED via the virtual link. If the negotiated bandwidth threshold is not exceeded, the received traffic is forwarded to the second ED via the virtual link. Otherwise, traffic with high priority is selected from the received traffic and forwarded to the second ED via the virtual link.
摘要翻译：本公开描述了在虚拟局域网（VLAN）部署在地理上分散的站点上的网络中的流量转发。网络包括在第一站点处的第一边缘设备（ED）和第二站点处的第二ED。在一个示例中，第一ED从第一站点内的主机设备接收流量。所接收的业务将经由在第一ED和第二ED之间建立的虚拟链路被转发到第二ED。第一ED确定所接收的流量所需的带宽是否超过第一ED和第二ED之间协商的带宽阈值，用于第一ED通过虚拟链路将业务转发到第二ED。如果未超过协商的带宽阈值，则所接收的流量经由虚拟链路被转发到第二ED。否则，从接收到的流量中选择具有高优先级的业务，并通过虚拟链路转发到第二ED。
