The present disclosure discloses a method and apparatus for changing a resource state, a terminal, and a storage medium, which belong to the field of smart home. A system for changing a resource state that includes a first collection resource, a first intermediate-level resource, and leaf node resources can be established. By making the first collection resource obtain link information of each leaf node resource whose resource state needs to be changed, a request that includes a default interface of the leaf node resource may be generated for the leaf node resource, such that a state of the leaf node resource can be changed accurately by the system. Therefore, the present disclosure enables the control request issued by a client to be recognized and executed by each leaf node resource, thereby increasing reliability and stability of system control.

A maintenance recommendation for containerized services can find a time to perform maintenance on a particular service based on resource usage patterns such that the maintenance will have a reduced impact on dependent services. The dependent services can be determined for the particular service based on network interactions between the services.

The present disclosure discloses a method and network device for providing tiered network access based on user actions. Specifically, a network device can identify a social action performed by a user, where the social action is performed while the user is logged into a social network application. Furthermore, the network device can select a network access level of a plurality of network access levels based on the social action. Accordingly, the network device grants a client device corresponding to the user access to a network based on the selected network access level. Note that the network access level is selected from the plurality of network access levels based on a plurality of social actions performed by the user.

Some embodiments provide a method for a software-defined wide area network (SD-WAN) connecting first and second sites, with the first site including an edge node and the second site including multiple forwarding hub nodes. At the edge node of the first site, the method receives a packet of a particular flow including a flow attribute. The method uses the flow attribute to identify a hub-selection rule from multiple hub-selection rules, each hub-selection rule identifying at least one forwarding hub node at the second site for receiving one or more flows from the first site, and at least one hub-selection rule identifying at least one forwarding hub node that is not identified by another hub-selection rule. The method uses the identified hub-selection rule to identify a forwarding hub node for the particular flow. The method then sends the packet from the edge node at the first site to the identified forwarding hub node at the second site.

Methods, systems, and computer programs are presented for a switching server. One switching server includes a server, a switch module coupled to the server, and a switch controller coupled to the server and to the switch module. The server includes a processor executing an operating system that includes a network driver, and the network driver includes a first network device operating system (ndOS) program. Further, the switch module includes a switch fabric and input/output ports. The switch controller includes a processor and non-volatile storage, where the processor is configured to execute a second ndOS program. The first and second ndOS programs implement a global networking policy for a plurality of devices executing ndOS programs, the global networking policy including a definition for switching incoming packets through the plurality of devices executing the ndOS programs.

Techniques for utilizing virtual edge switches of cloud computing networks to send, receive, and store in respective virtual memory, associations between virtual resource and virtual edge switches for better convergence in virtual application centric infrastructure networks. Each virtual memory acts as a virtual endpoint database and contains a number of records indicating associations between each virtual endpoint and the virtual edge switch attached to the virtual endpoint. Each virtual edge switch is hosted by a physical server and is configured to forward communications received from separate physical servers in the cloud computing network to the virtual endpoints attached to the virtual edge switch. The advertisement messages are configured to be sent upon a new virtual resource or a migrated virtual resource spinning-up on a physical server. The advertisement message may be configured to store additional network routing information associated with the virtual machine hosting the virtual endpoint.

Systems, methods, and non-transitory computer-readable media can receive information about an application design plan. The application design plan can be associated with at least one deployment criterion. One or more available infrastructure resources can be identified based on the information about the application design plan. A plurality of deployment options can be determined based on the one or more available infrastructure resources. The plurality of deployment options can be determined to be compliant with the at least one deployment criterion. The plurality of deployment options can be ranked to produce an ordered set of deployment options.

A software-defined network-based method and system for implementing a content distribution network. An application function, control function, and network entity resource of a CDN are added respectively to an application layer, control layer, and data forwarding layer of an SDN. When a request for a CDN application is received, the SDN application layer generates resource requirement and service scheduling information based on the request, and transmits a reservation request for a resource required by the CDN application to an SDN control layer. The SDN control layer allocates a resource required by the CDN application to combine network load balancing and path policies and to generate a content routing table for data transmission, generating and transmitting L2 and L3 forwarding tables to the SDN data forwarding layer. When it receives content distribution and content delivery requests, the SDN data forwarding layer executes a CDN service-related operation based on the forwarding tables.

A system and method for implementing a CDN based on SDN are provided. The method includes: a complete service logic function of the CDN is added on an application layer of the SDN, and an application unit sends a resource requirement request and service orchestration request to an orchestration unit when receiving a CDN application request; the orchestration unit performs service orchestration in combination with related information of the SDN, sends a reservation request to a control unit to obtain a required resource, and then determines content distribution and content delivery paths in combination with network load balancing and routing condition; an L2 and L3 forwarding table is created and transmitted to a data forwarding unit according to related forwarding policy of an SDN control plane; and the application unit executes a related operation according to a content distribution or media access request, and the data forwarding unit forwards data.
