摘要： An example method comprises: generating a first packet, wherein a source address in the first packet comprises a network segment, a host segment, and a slice segment that comprises a slice identifier; sending the first packet to a destination node, so that if the destination node, after receiving the first packet, determines according to the network segment and the host segment that the source address in the first packet belongs to a specified slice network segment, the destination node clears the slice segment in the source address, uses the source address whose slice segment has been cleared as a destination address of a second packet, and sends the second packet to the head node; receiving the second packet; and if the destination address is the same as a host address of the head node, delivering the second packet up to a control plane. Thus, the second packet can be correctly delivered up to the control plane.

摘要： 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.

摘要： Disclosed are a method and a device for controlling an EVPN route. According to an example of the method, when receiving an EVPN route from a second VTEP device, a first VTEP device checks whether the EVPN route carries a role attribute. When determining that the EVPN route carries a role attribute and the carried role attribute is a specified first role attribute value, the first VTEP device controls the distribution of the EVPN route according to a set route synchronization control strategy.

摘要： The present disclosure provides a path selection method and apparatus. The method comprises: receiving a traffic scheduling request, wherein the traffic scheduling request comprises a requirement for path selection, a source node, and a destination node; determining, for each dedicated line cloud comprising both a source virtual node connected with the source node and a destination virtual node connected with the destination node, a dedicated line corresponding to the dedicated line cloud as a traffic forwarding path when static attribute of a link between the source node and the respective source virtual node and a link between the destination node and the respective destination virtual node, and/or a dynamic attribute of a link between the respective source virtual node and the respective destination virtual node satisfy the requirement for path selection. The present disclosure can implement path selection based on bandwidth and quality in a point-to-multipoint network by a controller.

摘要： A network device includes a switch chip and a CPU, wherein the switch chip at least includes a CPU interface, and the CPU at least includes a media access controller and a Buffer. The network device further includes a conversion apparatus. The conversion apparatus receives a first packet uploaded by the switch chip to the CPU through the CPU interface, obtains a second packet by migrating a private information header in an Ethernet header of the first packet to a specified position of the first packet, calculates a Cyclic Redundancy Check, CRC, code of the second packet, obtains a third packet by replacing a CRC code already carried in the second packet with the calculated CRC code, and sends the third packet to the Buffer on the CPU for buffering, wherein the specified position is a position other than the Ethernet header in the first packet.

摘要： A NAT method, apparatus and device are provided. According to the method, a target IP address and its reference port are obtained from a NAT resource pool, the reference port being a port in a corresponding consecutive port range. A first five-tuple is generated based on the target IP address, the reference port and an original five-tuple of the packet, and a second five-tuple is obtained by masking first-class bits of the reference port of the first five-tuple. Based on a hash result of the second five-tuple, a target bit indicating a non-conflicting state is determined from a pre-constructed bitmap. The state indicated by the target bit is set to be a conflicting state, and a target five-tuple is generated based on the target bit. The target five-tuple and the original five-tuple are recorded in a session table, and the packet is NAT-processed based on the target five-tuple.
