摘要： Systems and methods are disclosed herein that relate to reporting a multicast Medium Access Control (MAC) address used by a particular Protocol Data Unit (PDU) session in a cellular communications system. In some embodiments, a method performed in a core network of a cellular communications system comprises, at a User Plane Function (UPF), obtaining multicast MAC address information comprising a multicast MAC address to be used on a particular PDU session and information that identifies either or both of a User Equipment (UE) associated with the particular PDU session and the particular PDU session and reporting, to a Session Management Function (SMF), use of the multicast MAC address on the particular PDU session. The method further comprises, at the SMF, receiving the report from the UPF, and using the multicast MAC address to perform one or more operational tasks.

摘要： Transmission of guaranteed and non-guaranteed data packets on redundant links A node (110) of a data network classifies the data packets into multiple different classes. Further, the node (110) replicates the data packets according to a number of redundant links (LINK 1, LINK 2) configured for transmission of the data packets to obtain, for each of the redundant links (LINK 1, LINK 2), a redundant version of the data packets. For a first one of the classes, the node (110) marks all redundant versions of the data packets with a first indication that the data packet is a guaranteed data packet which is subject to a guarantee that the data packet is not dropped and not delayed by more than a certain delay limit. For a second one of the classes, the node (110) marks at least one of the redundant versions of the data packets with a second indication that the data packet is a guaranteed data packet which is subject to the guarantee and marks at least one other of the redundant versions of the data packets of with a third indication that the data packet is a non-guaranteed data packet which is not subject to the guarantee.

摘要： A method is provided for use at a first node of a network. The first node (B) has an input path for receiving Ethernet frames destined for a second node of the network. The first node (B) also has a first output (working) path for forwarding the received Ethernet frames towards the second node. A failure along the first output (working) path is detected at the first node. Following such failure detection, the received Ethernet frames are caused, at the first node, to be re-routed along a second output (backup) path, different to the first output (working) path, towards the second node. The re-routing is performed by using (e.g. referring to and/or changing) respective indications (VLAN1) applied to the Ethernet frames to distinguish those Ethernet frames to be forwarded along the first output (working) path from those Ethernet frames to be forwarded along the second output (backup) path.

摘要： A network node of a telecommunications network controlled by a link-state protocol includes a network interface which receives a message that contains information on a change in topology of the network. The node includes a processing unit that blocks forwarding of traffic to at least one neighbor node of the network at the network interface, agrees on the change in topology with the neighbor node; and unblocks the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology in a memory. A transient loop prevention method of a network node of a network having a plurality of a network nodes controlled by a link-state protocol includes the steps of receiving a message at a network interface which contains information on a change in topology of the network. There is the step of blocking forwarding of traffic to each neighbor node of the network at the network interface by a processing unit. There is the step of agreeing by the processing unit on the change in topology with the neighbor node. There is the step of unblocking the forwarding of traffic when the neighbor node has information about the topology which is the same as the information about the topology stored in a memory.

摘要： The invention discloses a method (200, 300, 400) for traffic control in a cellular telephony system (100) comprising a number of cells, each cell comprising at least one Radio Base Station, RBS, (170). The system (100) comprises at least one Radio Network Controller, RNC, (110 130 150), for the control of a number of Radio Base stations. The traffic between an RBS and an RNC comprises a number of flows. The invention is intended for the control of flows from the Radio Base Stations to their RNC. The method uses one control function for each flow from each of said Radio Base Stations, and also comprises a congestion detection function (220) which detects the presence or absence of congestion in the traffic from an RBS to an RNC, and which, upon detection of congestion reduces the bit rate of the congested traffic, and in the absence of congestion, increases the bit rate of the previously congested traffic.

摘要： A method performed by a network node of a communications network for enabling internet protocol, IP, based deterministic networking. The method comprises receiving a routing request from a software-defined networking (SDN) controller, particularly wherein the SDN controller is associated with a deterministic network (DetNet); determining whether the routing request conflicts with the routing of the communications network; and responsive to determining whether the routing request conflicts with the routing of the communications network, transmitting a response to the SDN controller indicating acceptance or denial of the routing request. The network node may be a Deterministic Networking Application Function (DetNet AF).

摘要： A method for packet or frame replication and elimination in a network, includes obtaining by a gate controller downstream information indicating which application instance in an application cluster is downstream active needing to send a stream of packets or frames in a downstream direction through the network. The method further includes, based on the downstream information, controlling by the gate controller a gate within a gate cluster that is associated with the downstream active application instance to be open state which operates to forward the stream of packets or frames in the downstream direction from the downstream active application instance to an associated packet or frame replication entity for replication and transmission via at least two disjoint paths through the network.

摘要： A method performed by a node (111), for handling one or more member streams (122, 123) split from a stream of frames. The node (111) supports at least replication function (133) and one elimination function (131), to process the one or more member streams (122, 123). The node (111) operates in a communications network (100). The node (111) assigns (401) an indication to a frame of one or more frames comprised in a first member stream (121) outgoing from the at least one elimination function (131). The indication is the same in every frame of the one or more frames. The indication identifies the first member stream (121) as an output member stream in the stream. The node (111) forwards (402) the first member stream (121) outgoing from the at least one elimination function (131), identified by the indication, to another function (132) supported by the node (111), or to another node (112).
