A fishing hook has a shank portion with a hook at one end, and a hairpin loop portion formed on an opposite end of the shank portion. The hairpin loop portion extending downwardly from the opposite end of the shank portion. The hairpin loop portion has a width or diameter that is less than a width or diameter of the shank portion. The hairpin loop portion has an end extending at an angle away from the shank. The hairpin loop portion has a longitudinal axis coplanar with a longitudinal axis of the shank portion. The shank portion and the hairpin loop portion define a line-receiving slot.

An optical add/drop multiplexer incorporates an integrated receiver module and an integrated transmitter which are interfaced to an intervening electrical network to provide an add/drop/pass-through functionality. The receiver module incorporates a wavelength demultiplexer which is in turn combined with optical/electrical converters PIN photodiodes, and amplifiers on a per wavelength basis to output a plurality of parallel electrical signals in response to a common optical input. The transmitter module combines an integrated plurality of drive circuits and lasers for converting a plurality of parallel input electrical signals to a plurality of optical signals, on a per wavelength basis, which in turn are coupled via an optical wavelength multiplexer to a common output optical fiber. The interconnected electrical network, ring mesh or tree, can provide a reconfigurable electrical add/drop interface to other portions of the network.

The present invention provides for a method for reserving spare bandwidth for a link in a communication network including a plurality of links. The method provides for monitoring the volume of traffic routed through each link of the communication network. A single link failure for each link is then simulated and the volume of traffic which would be rerouted through each link for maintaining communication and the volume of traffic removed from each link are determined for each simulated single link failure. The difference between the volume of traffic which would need to be rerouted through each link and the corresponding volume of traffic removed from each link is then computed, and a maximum difference value is determined for each link for all simulated single link failures. An amount of spare bandwidth equivalent to the determined maximum difference is then reserved for each link.

A content delivery network aggregator system is disclosed. A user requesting content from a content provider has his or her DNS request forwarded to a CDN selector. The CDN selector intelligently selects an optimal CDN from amongst a number of partner CDNs to provide the requested content. The CDN selector selects one of the plurality of content delivery networks for providing content to a user based upon an analysis of a plurality of performance variables for each of the plurality of content delivery networks.

An interconnect element incorporates a plurality of smaller, substantially identical, interconnect modules. Multiple identical elements can in turn be combined to form larger interconnect networks. Signal paths in the elements can be implemented with optical fibers or electrical conductors.

A method and system for designing a bi-connected ring-based network is provided, which designs from scratch or converts an existing network to a dual-homed ring-based network. The network covers the locations capable of being bi-connected with one or more cycles/rings. The traffic demand is then routed via the cycles, in such a way so as to minimize the amount of network traffic management equipment required.

The present invention provides for a method for reserving spare bandwidth for a link in a communication network including a plurality of links. The method provides for monitoring the volume of traffic routed through each link of the communication network. A single link failure for each link is then simulated and one volume of traffic which would be rerouted through each link for maintaining communication and the volume of traffic removed from each link are determined for each simulated single link failure. The difference between the volume of traffic which would need to be rerouted through each link and the corresponding volume of traffic removed from each link is then computed, and a maximum difference value is determined for each link for all simulated single link failures. An amount of spare bandwidth equivalent to the determined maximum difference is then reserved for each link.

A switch core is set forth that comprises a plurality of duplex switches that are interconnected with a interconnection fabric to implement, for example, strictly non-blocking operation of the switch core for reciprocal traffic. In one embodiment, an N-way reciprocal switch is implemented. The N-way reciprocal switch comprises a plurality of duplex switches numbering N of at least a 1&#xd7;(N&#x2212;1) switch type (e.g., the duplex switches have at least N&#x2212;1 ports available for connection to implement the interconnection fabric). The interconnection fabric interconnects the plurality of duplex switches so that each duplex switch is connected to every other duplex switch used in the interconnection fabric by a single connection. A similar an architecture using switches numbering N of at least a 1&#xd7;N switch type are also set forth. Still further, a plurality of duplex switches are used to implement an (n,m)-way switch that, in turn, can be used to construct a recursive LM-way switch core and/or recursively expand an existing Clos switch core.

A communication system () comprises a first network () including a source () arranged to transmit data and a second network () including a destination () arranged to receive the data. Interruptions in communication between the source and destination are reduced by providing a first primary node () and a first secondary node () in the first network (), and a second primary node () and a second secondary node () in the second network (). First and second sets of primary routes (and) and secondary routes (and) are provided within the first and second networks to facilitate delivery of data to various nodes.
