A relay apparatus is provided to specify, in a plurality of recording areas in an information table, a target recording area being a recording area which records a transmission source data-item included in a frame and indicating as transmission source a device having a lowest frequency of communication via the relay apparatus, in response to receiving an unrecorded frame via a port of a plurality of ports under a fully recorded state of the plurality of recording areas. The unrecorded frame is a frame including a transmission source data-item that is not recorded in any of the plurality of recording areas. The fully recorded state of the plurality of recording areas is a state where the transmission source data-item and the port data-item are recorded fully in each of all the plurality of recording areas included in the information table.

Embodiments of this application provide a data processing method and apparatus. The method includes: parsing, by a user plane data processing network element, a received packet and determining first service type information of a data flow to which the packet belongs; obtaining, by the user plane data processing network element, second service type information of the data flow from a data analysis network element; and processing, by the user plane data processing network element, the data flow based on the first service type information and the second service type information. With the data processing method and apparatus disclosed herein, accuracy in identifying a service type of transmitted data can be improved.

A receiving node receives a virtual LDP initialization (vInit) message from a first node, where the vInit message comprises a request to establish a vLDP session between a requesting node and a target node. If the receiving node does not own a destination address of the vInit message, the receiving node is determined to be a relay node. The relay node inserts a relay label into the vInit message, where the relay label is an outgoing label that the relay node uses to reach the first node, and forwards the vInit message toward the destination address. If the receiving node owns the destination address, the receiving node is determined to be the target node, which extracts a stack of relay labels from the vInit message. The relay labels are used to define a return path to the requesting node for messages transmitted over the vLDP session.

Embodiments are directed to receiving an original packet at a service function; determining, for a reverse packet, a reverse service path identifier for a previous hop on a service function chain; determining, for the reverse packet, a service index for the reverse service path identifier; and transmitting the reverse packet to the previous hop on the service function chain.

A distribution of a content selection being distributed throughout a wireless mesh network may be tracked. A wireless device in the wireless mesh network enables the content selection to be exchanged. Wireless devices then exchange the content, and a network topology is recorded in response. Finally, the network topology is reported to a reporting agent.

Systems, methods, and software described herein provide enhancements for deploying communication networks in clusters of satellite devices. In one example, a first set of satellite devices is configured to orbit in a first orbital configuration, and a second set of satellite devices is configured to orbit in a second orbital configuration. A communication network is formed among the satellite devices and is configured to selectively exchange communications among satellite devices in the first orbital configuration and satellite devices the second orbital configuration based at least in part on an operational status of the communication network.

A node (100) is configured for use in a communication network. The node (100) is configured to obtain a message with a source address and a destination address. The node (100) is also configured to determine whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route (16) from the destination address to the source address has been established. The node (100) is also configured to selectively transmit the message on a backward route (18) that is the reverse of the forward route (16), depending on the determining.
