Abstract: A method and apparatus for optimizing network delivery of fifth generation (5G) edge application services by weighting network latency along with a load, capacity, and preference of an application server to determine where to transmit a new flow of packets. By using the weighted approach, network traffic can be equalized among multiple instances (e.g., applications) with the same address.

Abstract: Described herein are methods and devices (e.g., routers) that add network services to a multiprotocol label switching (MPLS) network. A method can include a network device of the MPLS network receiving a packet, the network device of the MPLS network modifying the packet by adding multiple MPLS extension headers, wherein each of the multiple MPLS extension headers added to the packet is used to support a different one of multiple network services for the MPLS network, and the network device of the MPLS network forwarding the packet as modified to another network device of the MPLS network.

Abstract: A method performed by a network device for generating a distributed flow record. The method comprising determining whether information related to a packet flow associated with a packet should be recorded in a local flow record table (LFRT) of the network device based on a flow record bit in a packet header of the packet. When the information should be recorded, the method updates an existing flow entry for the packet flow in the LFRT, or creates the flow entry for the packet flow in the LFRT when there is available memory space. The method sets or maintains the flow record bit in the packet based on whether the information from the packet associated with the packet flow has been recorded as part of the distributed flow record by the network device.

Abstract: Described herein are methods and devices (e.g., routers) that add in-network services to a multiprotocol label switching (MPLS) network. A method can include a router of the MPLS network receiving a packet and modifying the packet by adding one or more MPLS extension headers, adding a header of the extension header(s), and adding an indication within an MPLS label stack that one or more MPLS extension headers have been added to the packet. The method can also include the router forwarding the packet as modified to another router of the MPLS network. In certain embodiments, an extension header label (EHL) within a label value field of a label stack entry indicates that one or more MPLS extension headers have been added to the packet. In other embodiments, a forward equivalent class (FEC) indicates that one or more MPLS extension headers follow the MPLS label stack.

Abstract: A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.
