SR-enabled network nodes capable of replicating and recombining data packets in a manner that enables reliable, low-latency communications. In an example embodiment, a replicator node transmits to a combinator node multiple copies of a payload over different respective network paths, with the SR headers of the corresponding packets each having a replication segment identifier or a respective SID stack that includes the replication segment identifier. The combinator node delivers/forwards to the corresponding application/destination only the first-to-arrive payload copy and discards any subsequent payload copies based on the replication segment identifier. Some embodiments may beneficially reduce latency and packet loss concurrently and consistently. For example, packet loss may be reduced due to the transmission of multiple copies of the same payload over multiple network paths. Effective latency may be reduced due to the selection of the first-to-arrive payload copy for delivery/forwarding.

Ultra reliable segment routing

A method for providing network access to a plurality of user entities through an access point, said access point comprising a LAN interface and a broadband network interface, the method comprising the following steps at a gateway device: establishing a second secure communication link with said access point; receiving an IP address allocation request from one of said plurality of user entities via said second secure communication link; accessing a AAA server to verify whether a successful authentication of said one of said plurality of user entities on the basis of data related to a mobile subscription associated with said one of said plurality of user entities has already taken place; and upon successful verification, completing an IP address allocation scheme with said one of said plurality of user entities and enabling relaying of data between said one of said plurality of user entities and a PDN; wherein said gateway device is adapted to aggregate a plurality of instances of second secure communication links from different access points towards said PDN.

A hybrid access gateway (HAG) apparatus for native bridged communication in a communication network may include an upstream interface configured for receiving downlink Open Systems Interconnection (OSI) layer 2 traffic in the communication network; at least one downstream cellular coupling interface configured to be communicatively coupled to a user equipment (UE) represented by an OSI layer 2 address via a cellular access network (e.g. a Radio Access Network or RAN) of the communication network; an inspection module configured for inspecting an OSI layer 2 header of the received traffic; and a direction module configured for, based on the inspected OSI layer 2 header, directing the received traffic to the user equipment via the at least one downstream cellular coupling interface.

The disclosure relates generally to supporting bonded services at non-anchor nodes. A non-anchor gateway device is configured to support service bonding for a user device and communication with an anchor node of the user device. The non-anchor gateway device is configured to associated a set of user device data plane connections of the user device to form a bonded session for the user device where the set of user device data plane sessions includes a first user device data plane connection associated with a first access network and a second user device data plane connection associated with a second access network. The non-anchor gateway device is configured to map user device traffic of the user device between the user device data plane connections of the bonded session and a user device data plane session between the gateway device and the anchor node for the user device.
