An aggregate port selection is received from user to bundle at least two individual data ports of the network device for single channel data transfer. The lowest common denominators of physical capabilities (speed and duplex) of selected ports on the network device is determined through an operating system. Downgraded physical capabilities of at least one of the at least two data ports are committed to match lowest common denominators of the at least two data ports. Data exchanges are conducted over the at least two ports of the network device according to LACP.

This application provides a packet processing method and a device. In this application, a control identifier field is added to a packet, and the control identifier field indicates whether forwarding of the packet is allowed when a resource corresponding to a slice identifier fails to be matched. The control identifier field and a slice identifier of a network slice are carried in the packet, so that the slice identifier and the control identifier field are transmitted on a network together. When a receive end fails to match the resource corresponding to the slice identifier, the receive end can discard the packet based on the control identifier field, instead of forwarding the packet by using routing information.

Example communication methods and communications apparatuses are provided to verify a user equipment route selection policy (URSP) used by a terminal apparatus. One example communication method includes obtaining information about a first application of at least one packet data unit (PDU) session, where the information about the first application is determined based on a first URSP, and then sending the information about the first application to a second network element, where the information about the first application is used to verify whether information about a second application of the at least one PDU session matches the information about the first application, and the information about the second application is information about an application to which a data packet in the at least one PDU session belongs.

A method, performed by an access and mobility management function (AMF), of providing information for a vehicle-to-everything (V2X) service is provided. The method includes receiving, from a user equipment (UE), a registration request message including information indicating that the UE is a V2X terminal, selecting, based on the registration request message, a policy control function (PCF) supporting the V2X service, receiving V2X policy information from the selected PCF, and providing the V2X policy information to a base station.

A network device has an input configured to receive a message relating to a given device attempting to forward one or more packets across a computer network. The message has given device information relating to the given device. In addition, the routing device also has a selector, operatively coupled with the input, configured to select (after receiving the given data) a given group routing policy from a plurality of group routing policies. Preferably, the selector is configured to select the given group routing policy as a function of the given device information. The routing device also has an output operatively coupled with the selector. The output is configured to cause routing of device communication across the network using link-layer routes specified by the given group routing policy.

The disclosure relates to a 5.sup.th generation (5G) or 6.sup.th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a first network entity in a wireless communication network is provided. The method includes transmitting, to a second network entity, a first message including data to be used in a plurality of networks included in a virtual network (VN) group, a VN identifier (ID), group data, and receiving, from the second network entity in response to the first message, a second message including the data to be used in the plurality of networks, the VN ID, the group data, information indicating a processing result related to the first message.

A customizable router manages traffic between application programming interfaces (APIs) of microservice applications (apps) that make up various features of a website. Various datastores may also be used to store information, such as information related to certain products, pricing, users, etc. In order for the website to function properly, the microservice apps communicate with one another and with the datastores. The customizable router is used to manage and route traffic between the microservice apps and/or datastores. The customizable router may, for example, route a universal resource indicator (URI) request for a webpage of a website to particular versions or revisions of a microservice app based on rules established for the customizable router. For example, a certain percentage of traffic may be routed to a first version of a microservice app, while a different percentage of traffic may be routed to a second version of the microservice app.

In one embodiment, a method includes receiving energy efficiency data from a plurality of nodes within a network. The method also includes determining an energy efficiency node quotient for each of the plurality of nodes within the network to generate a plurality of energy efficiency node quotients and determining an energy efficiency path quotient for each of a plurality of paths within the network to generate a plurality of energy efficiency path quotients. The method further includes determining one or more policies associated with the plurality of paths and selecting a path from the plurality of paths based at least on the plurality of energy efficient path quotients and the one or more policies.

Embodiments of this application disclose a service resource preconfiguration method and device, and a system. The method includes establishing a first working path, sending a first path message from a first node to a second node, the first path message including an instruction to the second node to preconfigure a second channel resource; and preconfiguring the second channel resource based on the first path message. Fast automatic service recovery can be implemented, and fault recovery performance can be improved.

Example network devices, systems, and methods are disclosed. In an example, a network device includes memory configured to store information associated with one or more service level agreements (SLAs) for applications in a software-defined wide area network (SD-WAN) and an application-based multipath routing (AMR) module including processing circuitry. The AMR module is configured to identify, based on criteria, one or more of the applications for AMR, wherein each criterion of the criteria is associated with a corresponding property of an application. The AMR module is configured to determine a breach of one of the SLAs on each WAN link associated with a first application of the identified one or more applications. The AMR module is configured to apply, in response to determining the breach, AMR for the first application.
