Systems and methods for efficient upstream multicast in passive optical networks. An upstream multicast source communicates an upstream multicast packet to the network. Subsequent downstream packet management achieved through use of source filters prevents a reflected copy of the original upstream multicast packets from being received by the upstream multicast source.

A method and a device for multicast packet processing are disclosed. The method includes: A first network device obtains a data packet; and the first network device generates a first multicast packet and a second multicast packet based on the data packet. The first multicast packet includes first iFIT information and a first multi-level flow identifier. The second multicast packet includes the first iFIT information and a second multi-level flow identifier. The first multi-level flow identifier and the second multi-level flow identifier are different, to identify different forwarding paths of the generated first multicast packet and second multicast packet respectively. In the method, in a point-to-multipoint multicast data flow transmission scenario, a plurality of multicast data flows can be identified, to perform iFIT detection on each of the plurality of data flows, so as to implement packet loss and delay detection, path restoration, and the like for the multicast data flows.

User traffic is processed in a virtualised network. First and second VNFs are initialised in the same network namespace as each other in user space in a host and have access to a shared memory region of the host. The first VNF processes user traffic and the second VNF provides a user plane service in relation to user traffic processed by the first VNF. The first VNF is used to establish a point-to-point, shared-memory interface between the first and second VNFs and is used to classify incoming user traffic. In response to the first VNF determining based on the classifying, that the incoming user traffic is to be subject to the user plane service, the first VNF is used to store the incoming user traffic in the shared memory region of the host to enable the second VNF to provide the user plane service in relation to the incoming trier traffic.

Policy based dual connectivity traffic steering is described herein. A master Long-Term Evolution (LTE) base station may operate in conjunction with a secondary New Radio (NR) base station to provide dual connectivity to user equipment (UE) operating in an environment. The LTE base station can steer traffic between the LTE base station and the NR base station based at least in part on policy information received at the LTE base station. The policy information can indicate, for a particular UE and for a particular Quality of Service (QoS) Class Identifier (QCI), whether the LTE base station can transfer a communication to the NR base station. Thus, traffic steering determinations can be based on the policy information, quality identifiers, device capability, signal strength(s), load level(s), and the like, thereby providing a flexible framework for steering wireless traffic in a dual connectivity environment.

Embodiments of the present disclosure relate to a method of controlling physical data rate for optimizing throughput of multicast transport channels in at least one multicast channel, wherein the allocation of the at least one multicast transport channel to the at least one multicast channel is controlled such that inter alia at least one of all multicast transport channels to be allocated currently is placed within one multicast channel during the common sub-frame allocation period according to a pre-defined ruling when all multicast transport channels to be allocated currently do not fit into the one multicast channel, wherein a remainder of all multicast transport channels to be allocated currently is buffered and scheduled to be transmitted in a following common sub-frame allocation period. Further, a system for controlling physical data rate for optimizing throughput of multicast transport channels is described.

MPDU transmission method and device for a multi-link system, MPDU reception method and device for a multi-link system, a storage medium, a transmitter and a receiver are provided. The MPDU transmission method includes: determining a frame sequence number space which includes a plurality of frame sequence numbers and is defined based on a triplet <U-ID_t, U-ID_r, TID>, wherein U-ID_t represents a unique identifier of a transmitter, and U-ID_r represents a unique identifier of a receiver; determining a transmission order of a plurality of MPDUs to be transmitted, wherein each of the plurality of MPDUs carries an MSDU; sequentially obtaining frame sequence numbers from the frame sequence number space based on the transmission order; and transmitting the plurality of MPDUs based on the transmission order. Disordered reception issues at the receiver in multi-link transmission may be solved.

A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

Disclosed are a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for event messaging over a network. A subscription interface receives data indicative of a subscription request for sessionized data. An allocation module allocates a sessionizer bank linked to the subscription request. A messaging interface module provisions identifiers linked to the respective processing engines of the sessionizer bank. The messaging interface module registers the allocated sessionizer bank as available to process event messages matching the subscription request by providing the provisioned identifiers. The messaging interface module receives event messages from a producer device linked by a collection server to a selected one of the processing engines of the sessionizer bank. The selected one of the processing engine processes the received event messages in accordance with session rule data linked to the subscription request to generate sessionized data.

A system and method for managing bandwidth of an upstream communications channel in a communications system.

A method for transmitting data stream packets within a wireless communication network, includes the following steps: at at least one node: computing, from the signatures Si of the streams Fi to which the node has subscribed and for each of these streams Fi, reserved resources RBres wherein there is no collision, and resources RBcomp potentially in competition, wherein collisions are possible, checking whether the current resource RB is reserved or whether it is in competition, if the current resource RBres is reserved, if the node is the packet transmission source or if the node has already correctly decoded the packet, transmitting the packet of the stream associated with the resource, if not, attempting to decode the packet of the stream and, if the decoding is correct, storing the decoded packet in memory, if the current resource RBcomp is in competition, applying a method for managing stream collisions on the resources where n>1.
