摘要： The present disclosure provides radio frequency (RF)-based OTN systems and methods. This includes a framework to carry services over RF-based links without using SONET/SDH or asynchronous radio. In an exemplary embodiment, the present disclosure utilizes an OTN framework over RF. Additionally, the present disclosure can also apply to other non-OTN frameworks such as an extended Ethernet frame with forward error correction (FEC) over RF-based links. The present disclosure combines existing OTN FEC with a radio FEC or with an over-the-air FEC to reduce the OTN FEC. Additionally, the present disclosure utilizes unused overhead to communicate RF data rates between radios.

摘要： Apparatus and method that increases bandwidth and reliability of digital subscriber line (DSL) connections. The system involves provisioning multiple DSL lines, splitting traffic into cells, transmitting the cells independently of each other, and reassembling the cells at the destination. Sequence numbers may be used when reassembling the cells. Virtual circuits (VCs) may be constructed across the DSL lines. Accordingly, a failure in one DSL line merely reduces the bandwidth without disruption to the customer. In this manner, the customer can be inexpensively provided with increased bandwidth and reliability.

摘要： A method may include detecting a position of a first probe based on a placement of the first probe relative to a first zone on a surface of a device, obtaining a first target position for the first probe in the first zone, comparing the position of the first probe to the first target position, and generating a first haptic response to guide the first probe toward the first target position when the position of the first probe is outside a first predetermined tolerance relative to the first target position. The first haptic response may vary with the position of the first probe.

摘要： The present disclosure relates a network, a network element, a system, and a method providing an efficient allocation of protection capacity for network connections and/or services. These may be for services within a given Virtual Private Network (VPN) or Virtual Machine (VM) instance flow. Network ingress/egress ports are designed to be VM instance aware while transit ports may or may not be depending on network element capability or configuration. A centralized policy management and a distributed control plane are used to discover and allocate resources to and among the VPNs or VM instances. Algorithms for efficient allocation and release of protection capacity may be coordinated between the centralized policy management and the distributed control plane. Additional coupling of attributes such as latency may provide more sophisticated path selection algorithms including efficient sharing of protection capacity.

摘要： Systems and methods for self-healing Ethernet topologies which are compatible with PBT, which use standards-based protocols, which do not self-configure, and which use Ethernet OAM are provided. Interconnected nodes are configured with a primary and secondary path which is determined by VLANs, MPLS label, Provider Backbone Bridge Traffic Engineering (PBB-TE) VLAN ID (VID), Frame Relay (FR), Asynchronous Transfer Mode (ATM) Virtual Circuits (VCs), and the like. One or more head-end nodes are designated for terminating each path and for performing cross-connects between the primary and secondary paths. IEEE 802.1ag Continuity Check Messages (CCM) are transmitted by all nodes on both the primary and secondary routes. Responsive to a loss of a predetermined number of CCM messages, traffic is switched to the secondary route. In non-fault conditions, both the paths for the primary and secondary routes can carry traffic.

摘要： A system enhances automation of activating network service between a customer modem and a central office modem over a digital subscriber line (DSL) link. The central office modem couples the customer modem to a network for providing the network service. The system comprises a polling system coupled with the central office modems. The polling system polls inactive central office modems in order to detect the presence of an associated customer modem. A discovery application is coupled with the polling system and the central office modems for selectively enabling ones of the central office modems in accordance with a result of the polling system. If the polling system detects the presence of the customer modem, the associated central office modem is enabled for providing network service to a customer.
