A network device may select a first user plane function for establishing, with a user equipment, a protocol data unit session with a single flow and may receive an application function trigger associated with a first new flow for a first application of the user equipment. The network device may select a second user plane function for the first new flow and may create a first traffic filter for the first new flow. The network device may cause the first traffic filter to be provided to the user equipment so that first application traffic is routed, based on the first traffic filter, to the second user plane function and a first multi-access edge computing device associated with the second user plane function.

In a slice-based network, switches can be programmed to perform routing functions based on a slice identifier. The switch can receive a packet and determine a slice identifier for the packet based on packet header information. The switch can use the slice identifier to determine a next hop. Using the slice identifier with a multi-path table, the switch can select an egress interface for sending the packet to the next hop. The multi-path table can ensure that traffic for a slice stays on the same interface link to the next hop, even when a link aggregation group (“LAG”) is used for creation of a virtual channel across multiple interfaces or ports.

There is provided a system including a platform controller for managing artificial intelligence services, wherein the system includes a processor coupled with a memory, having stored thereon instructions. The instructions, when executed by the processor, configure the platform controller to receive an artificial intelligence (AI) service registration request from an AI controller controlling the AI service, the AI service registration request including information indicative of locations of the AI service and transmit an AI service registration response to the AI controller, the AI service registration response including routing information at least in part specifying how to reach a coordinator associated with the AI service, the coordinator corresponding to a location of the AI service and transmit a notification indicative of availability of the AI service to a device. When a request for access to the AI service is received from the device, the platform controller is configured to transmit a response to the device, wherein the response is indicative of whether the request is accepted.

Apparatuses, methods, and systems are disclosed for data packet routing in a remote unit. An apparatus includes a processor that receives a data packet to be transmitted and determines packet routing information for the data packet, the packet routing information comprising at least one of: network slice information, a continuity type, and a data network name for the data packet. The processor also determines whether the packet routing information matches a network connection and sends the data packet over a matching network connection, in response to determining that the packet routing information matches a network connection. In some embodiments, the apparatus includes a transceiver that communicates with a mobile communication network using at least one network connection of a first connection type associated with network slice information, a continuity type, and a DNN.

Provided is an incident effect range estimation device which estimates the range of the effect of an incident and shortens incident handling time. This incident effect range estimation device is provided with an incident origin log acquisition unit which acquires log information for the incident-originating device which is related to the occurrence of the incident, a communication destination log acquisition unit which acquires, on the basis of the log information for the incident-originating device, log information for a communication destination device which is the communication destination of the incident-originating device, and an effect range estimation unit which estimates the range of the effect of the incident on the basis of the communication destination device. The range of the effect of the incident can thereby be estimated automatically, and thus incident handling time can be shortened significantly.

A service function chaining (SFC)-based packet forwarding method, an apparatus, and a system, where the packet forwarding method includes receiving, by a first service function forwarding node, a packet forwarding rule from a control node, where the packet forwarding rule indicating a mapping relationship between a match item of traffic characteristic information of a packet and route prefix information, receiving, by the first service function forwarding node, a first packet, where a header of the first packet carries traffic characteristic information of the first packet, determining, by the first service function forwarding node based on the packet forwarding rule, target route prefix information corresponding to the traffic characteristic information of the first packet, determining, by the first service function forwarding node, target next-hop information based on the target route prefix information, and forwarding the first packet based on the target next-hop information.

The target switching device is configured to combine, based on the routing information, data reported by the plurality of computing nodes, and then send combined data to each computing node. The specified node is configured to send the routing information to each computing node, and each computing node may report data to the target switching device based on the routing information.

This disclosure generally relate to a method and system for network policy simulation in a distributed computing system. The present technology relates techniques that enable simulation of a new network policy with regard to its effects on the network data flow. By enabling a simulation data flow that is parallel and independent from the regular data flow, the present technology can provide optimized network security management with improved efficiency.

A method for evaluation of UE route selection policy (URSP) rules is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offloaded to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. Then, the UE selects a route selection descriptor including a preferred access type from a list of RSDs of the non-default URSP rule. After that, the UE matches or establishes a Protocol Data Unit (PDU) session for the application by ignoring the preferred access type or using the preferred access type.

Various techniques for dynamic path selection and data flow forwarding are disclosed. For example, various systems, processes, and computer program products for dynamic path selection and data flow forwarding are disclosed for providing dynamic path selection and data flow forwarding that can facilitate preserving/enforcing symmetry in data flows as disclosed with respect to various embodiments.
