摘要： A provider equipment having a backhaul resiliency module operable to determine multiple, alternative communication paths in a backhaul portion of a telecommunication network and then compare the different, alternative communication paths, based on their respective backhaul component reuse, to identify one or more resilient communication paths as options for a particular backhaul communication. The provider equipment can then select a preferred resilient communication path for either an uplink or a downlink of the backhaul network. Each of the alternative communication paths can correspond to a unique combination of Carrier Ethernet nodes and links that connect pairs of provider equipment devices located on opposing sides of a Carrier Ethernet, such as on a RAN side, an MSO side, or another Network side of the telecommunication network).

摘要： Techniques for allocating network resources of a communications network are described. A network resource scheduler allocates communication bursts to telecommunications devices in a manner so as to conserve power of the mobile telecommunication devices. The network resource scheduler may allocate communication bursts such that at least one of the mobile telecommunication devices may enter sleep mode during a current communications block and be awoken prior to a subsequent communications block.

摘要： Methods and computing systems for tunneling in a carrier transport network are described. An Internet Protocol (IP) packet having a destination IP address of a destination cellular site of a cellular cluster is received. A frame is formed with the IP packet placed into a payload portion of the frame. An outer Virtual Local Area Network (VLAN) tag that identifies a network of the cellular cluster to a first carrier network is added to the frame, and an inner VLAN tag that identifies the network of the cellular cluster to a second carrier is added. The first carrier network and the second carrier network are coupled via at least one network-to-network interface. The frame, including the IP packet, is forwarded to a provider edge switch of the first carrier network.

摘要： A mobile carrier may selectively offload backhaul data traffic between cell sites and the core network to existing alternative relay networks to increase available backhaul bandwidth to meet higher data traffic demands without adding additional network infrastructure. Data traffic may be offloaded from a cellular network to the alternative relay network based on at least one of a bandwidth capacity of the alternative relay network, a bandwidth availability of the alternative relay network, or a data class of the data. The amount of data that is offloaded to the alternative relay network may then be adjusted based on a blocking probability that is calculated for the alterative relay network.

摘要： In a network, communications between nodes in the network can be routed along different communication pathways. The network can include subnetworks provided and administered by third parties, and can include virtual private networks (VPNs), so the different pathways can be or include VPN tunnels that pass through different subnetworks of the communications network. A central controller can monitor performance of the pathways, including those not in primary use, and dynamically adjust routing of communications traffic between the nodes by directing communication traffic to specific pathways or tunnels. The controller can direct different types of traffic (eg. data, voice) to particular pathways, and can direct traffic to different pathways based on direction of traffic flow (for example, uplink along one pathway and downlink along another pathway). Application Programming Interfaces (APIs) can be provided to enable the controller to request changes to pathways by sending configuring information for routers in those pathways.

摘要： For a cluster of cellular communication sites, the power consumption and data load of each site is measured over multiple time periods to determine an energy factor indicating the degree by which the power consumption of each site increases with increasing data load. The energy factors are then analyzed to determine coverage area sizes for the communications sites that will serve a given area while taking advantage of more efficient site to reduce overall power consumption of the cluster of sites. Transmission power levels are then adjusted at the sites to achieve these coverage area sizes.

摘要： Methods and computing systems for allocating an information rate to a particular traffic type of a plurality of traffic types of egress traffic is described. A state of the particular traffic type for a particular time slot of a current time period is determined. This includes determining the information rate such that a loss probability threshold is not exceeded, based on historical data of the particular traffic type. The historical data includes a plurality of observed throughput rates of the particular traffic type during a plurality of previous time periods at which the particular traffic type experienced the state of the particular traffic type. The information rate (e.g., a committed information rate) is allocated to the particular traffic type for the particular time slot.

摘要： Disclosed herein are techniques for measuring inter-domain handoff performance between network devices in different network domains. A peer- based handoff performance measurement process may include generating test data to be transmitted from a first edge device of a first network domain over an interface to a second edge device of a second network domain, the test data having an identifier (ID) to indicate that the test data is to be used for measuring handoff performance over the interface. The first edge device may add a start time to the test data indicating a start of a measurement instance using the test data, transmit the test data to the second edge device over the interface, receive the test data with a receive time added by the second edge device, and store at least the start time and the receive time as handoff performance data.
