A geographical identification forwarding method for area-oriented addressing. The geographic location information is used as a transmission identification, and the communication process based on the geographical identification is realized by constructing the SDN-based geographical identification transmission architecture. In this method, a geographical identification is used instead of a traditional IP identification for network transmission, which effectively alleviates the problem of narrow waist of IP single bearing in the current network. At the same time, through a flow table decomposition design, the flow table size of the switch is effectively controlled. The method provided by the present invention can be extended to a plurality of geographical identification areas to realize large-area real-time cross-domain transmission. The method is simple to operate, easy to realize and high in real-time; the method has a wide application range, and can be used to build new networks and improve network performance.

A control apparatus includes a setting unit configured to perform a setting for forwarding a packet destined for first software to a second computer on a switch on a communication path from a first computer to the second computer during a migration of the first software from the first computer to the second computer, the first computer being a computer in which the first software and second software configured to communicate with the first software run, and a deletion unit configured to delete the setting from the switch when the migration of the first software is completed. Thus, the control apparatus shortens the time during which the setting of data forwarding remains at the switch.

Embodiments of this application provide a communication method and a related device. In the method, a control plane (CP) sends a first message to a user plane steering function (USF). The first message includes end user information, and indicates the USF to schedule an end user based on the end user information. Then, the CP determines, based on an identifier of a target UP carried in a first request message sent by the USF, to schedule the end user to the target UP. Thus, a scheduling policy of the end user is determined via the USF. The CP further processes a connection between the end user and the target UP based on the identifier of the target UP.

The disclosure provides a method and a device for efficiently operating network slicing. According to the disclosure, a method of operating a first node configured to manage a network slice of a communication system includes: transmitting a service level agreement (SLA) range for each network slice subnet and a message requesting a resource according to the SLA range to a second node configured to manage the network slice subnet, receiving SLA arrangement flavor mapping relationship information in the network slice subnet unit from the second node, and identifying the SLA arrangement flavor mapping relationship in a network slice unit based on the received SLA arrangement flavor mapping relationship information in a network slice subnet unit.

The present application relates to egressing traffic from a public cloud network. An egress traffic manager configures routing at hosts and edge routers within the public cloud network. The egress traffic manager determines, for an edge router, a plurality of current border gateway protocol (BGP) sessions with external networks. The egress traffic manager configures a virtual router hosted on the edge router to route a portion of egress traffic to a selected one of the external networks via one of the BGP sessions. A host is configured to route the portion of egress traffic within the public cloud network to the edge router. An edge router configured to route, by the virtual router, the portion of egress traffic from the edge router to the selected one of the external networks.

A storage system includes a switch and a plurality of storage nodes. The switch is configured to receive a first request from a client. The first request includes an identifier of a storage partition. The switch queries an entry in a forwarding table based on the identifier to determine a target storage node in the plurality of storage nodes. The entry includes a mapping relationship between the identifier and the target storage node. The switch sends the first request to the target storage node. The target storage node is configured to receive the first request from the switch.
