Various embodiments are directed to receiving, at a receiving device, a packet from a node in a first network. determining a version identifier for the packet, encoding the version identifier into the packet, and transmitting the packet containing the encoded version identifier to a load balancing device in a second network. The version identifier may be encoded into a destination port field of the packet. The receiving device may be a perimeter network address translation device. The packet is received at the load balancing device, where the version identifier is extracted and a hash of source address information is performed. The version and hash are used to select a back-end device in the second network. The packet is transmitted to the selected back-end device.

A medium access control circuit includes a processor, N hardware queues, and an interface circuit, where the N hardware queues are divided into a plurality of hardware queue groups. Where the first hardware queue group corresponds to a network property of the data frame based on a first mapping relationship, the first hardware queue corresponds to a service type of the data frame based on a second mapping relationship, the first mapping relationship includes mappings from network properties to hardware queue groups, and the second mapping relationship includes mappings from a plurality of service types to a plurality of hardware queues in the hardware queue group corresponding to the network property of the data frame; and then, the interface circuit sends the data frame from the N hardware queues through a radio channel.

The present disclosure relates to a device and method for providing a terminal with information of a server in a communication system and, more specifically, to a device and method for providing a terminal with information of an application server in a mobile communication system. According to an embodiment of the present disclosure, a terminal may receive, from a 5G system according to a location of the terminal, an address of a DNS server to access, and receive, from a 5GS, regional information or zone information (hereinafter, referred to as an edge computing service zone ID (ESZI)) which can be used when a query is transmitted to the DNS server. When transmitting a DNS query to the corresponding DNS server, the terminal may include the ESZI in the DNS query and transmit same, and the DNS server having received the DNS query may search for an edge application server operating in an edge computing environment suitable for (or close to) a current location of the terminal, determine an address of the edge application server, and respond to the terminal. Accordingly, the terminal may access an edge application server that is closest to or most suitable for the current location of the terminal, and use an edge computing service.

A MAP-T system that shares an IPv4 address with one or more other MAP-T systems identifies low latency (LL) traffic for an upstream and a downstream perspective by enhancing NAT of ports using MAP-T rules. The MAP-T rules provide a range of transport ports with a transport slice providing for a subdivision of the transports into a subnet range so as to isolate certain ports for mapping LL traffic. An access point device and a cable modem of the MAP-T system are configured so as to appropriately transform any received traffic so as to properly direct the traffic.

A cable communications network provides an alternative communications path between a user equipment device and a data network to a cellular path for a communications session with a desired level of Quality of Service. A cable modem termination system, coupled to a wireless core network, e.g., a 5G core network, interacts with the wireless core network to attempt to establish a PDU session for a UE with a desired QoS level. The core sends a QoS service request message to the CMTS including a requested level of QoS, an IP address and port number for the session. The CMTS and cable modem, corresponding to the UE, negotiate and decide if the request desired QoS level can be supported over the cable between the CMTS and the cable mode for the session.

A network device for use with a client device and a cable modem termination system (“CMTS”), the client device being configured to run applications requiring data traffic of a first and second quality of service (“QoS”). The CMTS is configured to provide a first service flow and a second service flow to the network device. The network device provides a local area network (“LAN”) for connection to the client device and a network address translation (“NAT”). The NAT is configured to map the network device IP address to the client device IP address; divide the source ports into a first range and a low latency range; assign the respective data traffic of the applications to at least one port within the first range and to at least one port within the low latency range; and modify the low latency range of source ports based on a change in data traffic.
