    Abstract: Systems, methods, and computer-readable media for the secure creation of application containers for 5G slices. A MEC application in a MEC layer of a 5G network can be associated with a specific network slice of the 5G network. A backhaul routing policy for the MEC application can be defined based on the association of the MEC application with the specific network slice of the 5G network. Further, a SID for the MEC application that associates the MEC application with a segment routing tunnel through a backhaul of the 5G network can be generated. A MEC layer access policy for the MEC application can be defined based on the SID for the MEC application. As follows, access to the MEC application through the 5G network can be controlled based on both the backhaul routing policy for the MEC application and the MEC layer access policy for the application.

    Abstract: Embodiments of this application provide a bit-forwarding ingress router, a bit-forwarding router, and an OAM test method, and pertain to the field of multicast networks. A first BFR receives an OAM request packet from a BFIR; the first BFR determines, according to the OAM request packet, that a destination BFR corresponding to the OAM request packet is the first BFR; and the first BFR obtains a first OAM response packet according to an ID of the BFIR, and sends the first OAM response packet to the BFIR. According to the method and the apparatus that are provided in the embodiments of this application, a problem that a BFIR cannot diagnose or handle a transmission fault when the fault occurs during transmission of a multicast packet can be resolved, which helps implement connectivity testing by using an OAM packet and enables testing of multiple BFERs.

    Abstract: A method and apparatus of a network element that processes network data using a transformed packet classification list in a network element is described. A network element receives a packet classification list and transforms a first set of the plurality of range sets corresponding to a first one of the two or more types of packet characteristics into a first set of range labels. In addition, the network element transforms a second set of the plurality of range sets corresponding to a second one of the two or more types of packet characteristics into a second set of range labels. The network element may create a set of combination labels. The network element further processes network data by performing a first lookup to derive a first combination packet label, performing a second lookup of at least the first combination packet label, and applying a rule resulting from the second lookup to the network data.

    Abstract: A processing device can receive a request directed to an application such as a service and parse the request to determine a version identifier based on the content of the request. The processing device can acquire a version label corresponding to at least one instance of the application from among multiple instances of the application and match the version label and the version identifier, providing automatic detection and routing of a request to an instance of an application with the correct version. The computing device can store version labels and routing rules for each instance among the multiple instances of the application deployed in the network prior to receiving requests, or determine version labels and routing when a request is received.

    Abstract: A method, computer-readable medium, and apparatus for supporting services for customer traffic using edge clouds are disclosed. For example, a processing system may receive an indication of a set of customer devices of a customer of a network provider and an indication of a service of an edge cloud to be applied to customer traffic of the customer devices, support configuration of a network of the network provider to support a customer segment for the customer including configuration of a gateway of the network and a switch of the network that is associated with the edge cloud, support configuration of a virtual network between the switch and an edge cloud element supporting the service, and support configuration of the switch to support an association of the customer segment and the virtual network for supporting routing of the customer traffic to the service via the virtual network.
