    摘要： Methods and apparatus to manage bypass paths in an Internet protocol (IP) network are disclosed. An example method disclosed herein includes receiving IP traffic at an aggregation router and measuring a bandwidth value of the IP traffic forwarded from the aggregation router to an IP router at a starting node. The example method also includes establishing a first non-routed bypass path between a switch at the starting node and a first switch at a first destination node when a measured traffic throughput value of the IP router at the starting node exceeds a first threshold value, and sending the IP traffic from the aggregation router via the bypass path.

    摘要： This is a method for use in architecting low cost networks using a thin optical transport layer. A long reach hot pluggable interface is inserted onto an electrical switch resulting in a standardization of the optical layer. Standardized parts like the long reach hot pluggable interfaces and standard control planes form the logic that connects components of the low cost optical layer. After the components are in place, provisioning is done at end points only. This ensures an automatic and fast turn-up capacity without the need to visit intermediate sites in the network.

    摘要： A network arrangement where traffic elements of network nodes are programmable. A traffic element comprises electrically controllable transceiver pool having one or more ports that are coupled to an electrically controllable optical director that has all-optical information communication paths. The transceiver pool has one or more customer connection points in addition to the one or more connection points that connect to the optical director, and is adapted to couple a signal from any of the customer connection points to the optical director, at a particular wavelength. The choices for the specific coupling within the optical director and of the wavelengths are specified by control signals that are applied to the transceiver pool and to the optical director.

    摘要： A method for cost-effective optical transmission with fast Raman tilt or other transient event control uses a combination of Erbium-doped fiber amplifiers (EDFAs) and Raman fiber amplifiers (RFAs), where EDFAs are used as the primary optical amplifiers to compensate the span loss while the RFA (advantageously a forward-pumped RFA) is used only in some specific spans with a feed-forward control circuit serving as a fast Raman tilt transient compensator, the RFA also serving as an optical amplifier. A long haul optical transmission system using feed-forward controlled RFA's periodically spaced along its length, for example, when add-drop multiplexing is used, makes full use of the economics of EDFAs and the fast tilt transient control capability of a RFA enabled by an adjustable speed feed-forward or feed-back control technique.
