According to an aspect, an existing end-to-end bearer data path of communication between a wireless device and an endpoint in a core network is modified. The wireless device receives parametric information identifying respective service capabilities of network nodes in the core network that are available for forming alternate end-to-end bearer data paths of communication between the wireless device and the endpoint. The parametric information is used to determine that a more favorable end-to-end bearer data path of communication between the wireless device and the endpoint is available. The more favorable end-to-end bearer data path has a more favorable service capability in the core network as compared to the existing end-to-end bearer data path. The wireless device requests a path modification from the existing end-to-end bearer data path to the more favorable end-to-end bearer data path.

A broadband network gateway (BNG) controller is described that includes a network subscriber database (NSDB) and one or more core applications. The NSDB is configured to store vBNG instance information for one or more subscriber devices. The vBNG instance information specifies vBNG instances operable by one or more edge routers. The vBNG instances are configured to receive requests to access service provider services from the one or more subscriber devices and to selectively authenticate the one or more subscriber devices for network services based on authentication information included in the requests to access services provider services. The one or more core applications include a network instance and configuration manager (NICM). The NICM is configured to modify the vBNG instance information at the NSDB to include an additional vBNG instance and to output, to an edge router, an instruction to generate the additional vBNG instance at the edge router.

A network interface controller (NIC) capable of efficient packet forwarding is provided. The NIC can be equipped with a host interface, a packet generation logic block, and a forwarding logic block. During operation, the packet generation logic block can obtain, via the host interface, a message from the host device and for a remote device. The packet generation logic block may generate a plurality of packets for the remote device from the message. The forwarding logic block can then send a first subset of packets of the plurality of packets based on ordered delivery. If a first condition is met, the forwarding logic block can send a second subset of packets of the plurality of packets based on unordered delivery. Furthermore, if a second condition is met, the forwarding logic block can send a third subset of packets of the plurality of packets based on ordered delivery.

A computer implemented system is provided for improving performance of transmission in real-time or near real-time applications from at least one transmitter unit to at least one receiver unit. The system includes an intelligent data connection manager utility that generates or accesses performance data for two or more data connections associated with the two or more communication networks, and based on the current performance data determining current network transmission characteristics associated the two or more data connections, and bonds the two or more data connections based on: a predetermined system latency requirement; and dynamically allocating different functions associated with data transmission between the two or more data connections based on their respective current network transmission characteristics. The data connection manager utility then manages dynamically the transmission of relatively large data sets across the two or more bonded or aggregated data connections in a way that meets the system latency requirement and improves performance in regards to other network performance criteria (including data transfer rate, errors, and/or packet loss). Related computer implemented methods are also provided.

Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.

Examples described herein relate to a network interface device that includes circuitry to: adjust a rate of packet transmissions by Explicit Congestion Notification (ECN)-based congestion control based on phase of operation and congestion metrics comprising queue depth at one or more intermediate switches. In some examples, the circuitry is to adjust the rate of packet transmissions by multiplicative decrease or increase based on a number of inflight bytes. In some examples, the circuitry is to adjust the rate of packet transmissions by additive decrease or increase based on congestion metric from the one or more intermediate switches at one or more intermediate switches.

The present disclosure relates to End-to-End (E2E) Quality of Service (QoS) monitoring for strict E2E performance requirements in 5G networks including Network Slices (NSs) or Network Sub Slices (NSSs). The present disclosure provides a a control plane entity for obtaining NS Instance (NSI) data for analytics from a management plane entity, and a management plane entity to provide NSI data to a control plane entity. The control plane entity is configured to request NSI topology information from the management plane entity, obtain at least one first set of Key Performance Indicators (KPIs) or at least one set of measurements, and generate the data for analytics based on the requested NSI topology information and at least one of the obtained first set of KPIs or the obtained one at least one set of measurements.

An information processing apparatus includes a transmission module to transmit data quantity information and data frame sequences at a first transmission rate and a reception module to receive the information and data frames and to transmit a reception buffer free capacity value. The transmission module includes a unit to set the data quantity information according to the reception buffer free capacity value and a transmission unit to transmit a sequence of data frames after the data quantity information for the sequence has been transmitted. The reception module includes a buffer to store the data frame sequences from the transmission module and a unit to calculate an expected free capacity for the buffer with the transmitted data frames stored therein. The expected free capacity is calculated using the data quantity information and is transmitted as the reception buffer free capacity value at a second transmission rate.

A method for establishing a temporal label switched path (T-LSP) implemented in a node in a network. The method includes receiving a path request including a time interval and a set of constraints; obtaining traffic engineering information from a first database; computing, by the node, a path satisfying the time interval and the set of constraints based on the traffic engineering information obtained; storing the time interval and the set of constraints in a second database; and instructing an ingress node of the temporal LSP to signal the temporal LSP in the network along the path computed at a start of the time interval identified in the path request and to tear down the temporal LSP at an end of the time interval identified in the path request.

A method comprises storing, at the source node, data frames into a buffer for transmission to the recipient node over a host-to-host protocol connection; measuring, at the source node, a connection quality of the host-to-host protocol connection; adjusting, at the source node, one or more target parameters of the transmission on the basis of the measured connection quality; transmitting, by the source node, data frames from the buffer to the recipient node on the basis of a Last-In, First-Out (LIFO) method and the adjusted one or more target parameters.
