摘要： A method and member device for forwarding service messages in an Intelligent Resilient Framework (IRF) system and an IRF system. In the method, each member device in the IRF system is allocated to at least two virtual devices, and at least one stack link for each virtual device is configured in order to connect interface boards among different member devices. When it is determined according to a forwarding entry of an interface board in a first member device receiving a service message that the service message is to be transmitted to a second member device, the service message is forwarded via the at least one stack link configured for the virtual device of that interface board.

摘要： A method for controlling flow and a chassis switch in a stack system are provided. The stack system includes multiple chassis, each of the multiple chassis includes a main control board and an interface board, traffic flow and control flow in each of the multiple chassis are independent of each other when each of the multiple chassis operates normally. In the method, when a main control board in a chassis in the stack system is unavailable, control flow to be transferred to a destination interface board is switched to a traffic flow channel corresponding to the destination interface board from a control flow channel, and the control flow is transmitted to the destination interface board through the traffic flow channel.

摘要： In an example, after receiving a first multicast packet from an underlay network, a virtual switch (vSwitch) determines a first virtual machine (VM) corresponding to a first underlay network multicast group identity and a first overlay network multicast group identity in the first multicast packet by using a category-1 entry, performs VXLAN decapsulation on the first multicast packet and sends the decapsulated first multicast packet to the first VM. After receiving a second multicast packet from a second VM, the vSwitch determines a second underlay network multicast group identity corresponding to a tenant ID of a tenant to which the second VM belongs and a second overlay network multicast group identity in the second multicast packet by using a category-2 entry, performs VXLAN encapsulation on the second multicast packet using the second underlay network multicast group identity, and forwards the encapsulated second multicast packet to the underlay network.
摘要翻译：在一个示例中，在从底层网络接收到第一多播分组之后，虚拟交换机（vSwitch）在第一多播中确定与第一下层网络多播组标识相对应的第一虚拟机（VM）和第一覆盖网络多播组标识通过使用类别1条目来对第一组播数据包执行VXLAN解封装，并将解封装的第一个组播数据包发送到第一个虚拟机。在从第二VM接收到第二组播数据包之后，vSwitch通过使用第二组播数据包，确定与第二虚拟机所属租户的租户ID相对应的第二下层网络组播组标识，以及第二组播组标识中的第二覆盖网络组播组标识一个2类入口，使用第二个底层网络组播组标识在第二个组播数据包上执行VXLAN封装，并将封装的第二组播数据包转发到底层网络。
