A Provider Network Controller (PNC) addresses the challenges in building services across Next Generation Network (NGN) architectures and creates an abstraction layer as a bridge, or glue, between the network transport and applications running over it. The PNC is a multi-layer, multi-vendor dynamic control plane that implements service activation and Layer 0-2 management tools for multiple transport technologies including Carrier Ethernet, Provider Backbone Transport (PBT), Multi-protocol Label Switching (MPLS), Transport MPLS (T-MPLS), optical and integrated networking platforms. Decoupling transport controls and services from the network equipment simplifies service creation and provides options for carriers to choose best-in-class equipment that leverages the PNC to enable rapid creation and management of transports and services. The PNC provides Service-Oriented Architecture (SOA) interfaces to abstract transport objects expressly designed to support both wholesale and retail services, and supports service offerings with varied bandwidth and Quality of Service (QoS) requirements, thus achieving enterprise Ethernet economics.

Systems and methods for dynamically controlling vergence and focus for a see-through head-mounted display (ST-HMD) used as part of an augmented reality (AR) system are disclosed. The ST-HMD (40) allows a user (30) to view left and right images (150L, 150R) through corresponding left and right eyepieces (104L, 104R) so that a single virtual object (150V) based on the right and left images as seen at a real object such as a screen (20). When the user moves relative to the real object, however, the vergence changes and the virtual object does not appear in focus at the real object. Changes in the vergence are compensated by tracking the user's head position with a tracking unit (350) and providing the tracking data to a controller (180). Based on the tracking data and the interpupilary distance (IPD) of the user, the controller calculates the offset (H) needed to be imparted to the images formed in the eyepieces to maintain the vergence of the virtual object at the real object even when the user's position changes relative to the real object.

Available bandwidth utilization during transfer of large files over a TCP / IP network is improved by load balancing data streams and dynamically controlling the number of data streams utilized. A determination is made of the optimum number of data streams for a particular data file transfer in the early stage of transmission. An initial number of data streams, which is one unless otherwise specified or determined, is used to transmit one or more file segments, each on a different data stream, immediately followed by a second initial number of data streams, which is at least two greater than the initial number of data streams, is used to transmit another portion of the large data file. During each transmission, individual and aggregate transmission bandwidths are determined. Responsive to a determination that the latest aggregate transmission bandwidth is significantly different from the previous aggregate transmission bandwidth, the number of data streams is modified.

The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read / write accesses (I / Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I / O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I / O streams is used to apply controls to guarantee quality of service to all I / O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I / O stream is created that will always be applied to that I / O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I / O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.
