Traffic data is divided into data streams corresponding to workloads, and the data streams are multiplexed onto slice segments based on a multiplexing requirement or rule. Each slice segment is a physical or virtual processing element in a wireless network supporting network slicing. In one example, the data streams are multiplexed onto the slice segments such that data streams having different utility definitions are assigned to different slice segments. In another example, the data streams are multiplexed onto the slice segments such that workloads in the same cluster partitioned in a T-dimensional vector space are assigned to different slice segments.

Method and apparatus for reducing network latency

It is possible to dynamically configure buffers in network devices by sending software defined network (SDN) instructions to a Control-to-Data-Plane Interface (CDPI) agents on the network devices. An SDN instruction may instruct a CDPI agent to configure a buffer in a network device to store a specific type of traffic flow in accordance with a traffic handling policy. In some embodiments, the SDN instruction instructs the CDPI Agent to directly configure a buffer by, for example, associating a virtual port with a new/existing buffer, binding a virtual port associated with the buffer to a switch, and/or installing a flow control rule in a flow table of the switch. In other embodiments, the SDN instruction may instruct the CDPI agent to reconfigure the buffer by transitioning the buffer to a different state.

Method and apparatus for programmable buffers in mobile networks

Interruptions in communication due to user equipment (UE) handovers (HO) are signaled from the mobile communication network to the traffic source. For ultra-low latency and reliable communication, the signaling of HO start and completion notifications prevents retransmissions of in-flight packets by the traffic source, eliminating additional delays and inefficiencies. Signaling can be implemented by a network element, by a network element in conjunction with a smart traffic handler between the network and the traffic source (e.g., applications) and by a UE having at least two different radio interfaces.

Disclosed within is a communication architecture for medium access control (MAC) layer virtualization, where the architecture is made up of: a physical MAC layer, a plurality of physical resource blocks (RBs) associated with the MAC layer, a plurality of virtual medium access control (vMAC) layers, where each vMAC layer corresponds to a separate service group, with each service group programming its own scheduling logic in each vMAC layer, and a plurality of virtual resource blocks (vRBs) associated with each vMAC layer, where the vRBs are filled with data packets according to the scheduling logic in each vMAC instance. The physical MAC layer virtualizes the RBs as vRBs and assigns them to each vMAC layer according to a service level agreement associated with each service group, and each vMAC maps traffic flows of subscribers associated with it onto the assigned vRBs.

Method and apparatus for virtualized scheduler

One or both end points of the communication and a network controller of a software defined network (SDN) agree on a definition of a traffic flow that varies as a function of time, where communicating end points vary one or more fields of the packet headers at the sender side before sending the flow packets to the network according to an agreed upon procedure with the network controller. The network controller dynamically updates the forwarding tables in forwarding elements such that whenever source node transitions into the next epoch, and thus alter the header fields, a corresponding forwarding rule is already installed onto the forwarding elements along the route of the packet towards the other end point of the communication, referred to as destination node.
