摘要： A system, device, and method for bandwidth management in an optical communication system uses an optical service agent to provide bandwidth management services on behalf of a user. The optical service agent may monitor bandwidth utilization on a connection, control bandwidth utilization on a connection, obtain additional bandwidth for a connection, relinquish excess bandwidth for a connection, and allocate bandwidth among multiple connections, to name but a few. The optical service agent may interact with an optical communication network and/or various peer users in order to obtain and reserve communication services.

摘要： A system, device, and method for managing service level agreements in an optical communication system uses an optical service agent to manage a service level agreement (SLA) for a user. The optical service agent can perform both real-time and off-line analysis for the user, and can interact with various network elements (including the core optical communication network) to handle billing, penalty, and other issues associated with a SLA breach. Among other things, the optical service agent may monitor and analyze a connection in real-time for determining SLA compliance, gather and maintain statistical information relating to a connection, analyze the statistical information off-line for determining SLA compliance, patterns, and trends, interact with a service provider to enforce penalty provisions in the SLA, interact with a service provider to negotiate a credit for services not provided by the service provider in accordance with the SLA, interact with a service provider to negotiate “replacement” services for a breach of the SLA, interact with various network elements to rectify a breach of the SLA, interact with the service provider to dynamically modify the SLA based upon changing user requirements, and interface with a billing/accounting system to provide SLA-related information.

摘要： A system and apparatus for dropping and adding optical data streams in an optical communication network uses a photonic switching fabric for dropping but not adding optical data streams, and uses a combiner external to this photonic switching fabric for combining passed optical data streams from the photonic switching fabric together with added optical data streams. The added optical data streams are not limited to the wavelengths of the dropped optical data streams. The photonic switching fabric may be a Micro Electro Mechanical System (MEMS) that uses single-sided mirrors configurable to drop but not add optical data streams.

摘要： A method of improving modal bandwidth in computer networks using multimode optical fiber and single mode sources is disclosed in which the optical signal from a center of the optical fiber is prevented from reaching the detector. This is accomplished according to a number of different techniques including the use of opaque spots on the fiber media/fiber couplers or the use of dark-cored fiber couplers. These configurations prevent pulse splitting that occurs in single mode source/multimode fiber systems by preventing light from the multimode fiber's center from interfering with the detector. When this is achieved, the detector is insulated from the effects of pulse splitting, supporting increased data rates by increasing the modal bandwidth.

摘要： Input values are data encoded for improved signal characteristics (e.g., limited maximum run length and limited cumulative DC-offset) so as to form "data codewords, " and then a number of the data codewords, collectively referred to as a block, are error protection encoded, preferably using a conventional linear and sytematic forward error control ("FEC") code, to yield an FEC code block. Preferably, an FEC code block is formed by generating a number of check bits or FEC bits equal to the number of data codewords in the block, and then concatenating one FEC bit and its binary complement with each data codeword, so that one FEC bit and its complement is interposed between each successive codeword.

摘要： A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interface directly with the optical communication network.

摘要： An optical switch router performs both optical switching and traditional routing. The optical switch router includes optical interfaces for coupling to one or more incoming optical fibers and to one or more outgoing optical fibers, and also includes a number of traditional router ports. Individual incoming optical data streams received over the incoming optical fiber(s) can be selectively passed through to one or more of the outgoing optical fibers or “dropped” from the optical communication path for traditional routing. Routed traffic, which can be received over the router ports or from the “dropped” optical data streams, can be forwarded over optical data streams that are “added” to the outgoing optical fiber(s). The “added” optical data streams may be added to the outgoing optical fiber(s) at any unused wavelengths, including, but not limited to, the wavelengths of the “dropped” optical data streams.

摘要： A system, device, and method for managing alternate site switching in an optical communication system recovers from failures/degradations that are uncorrected by the core optical communication network. When an uncorrected failure/degradation is detected, communications for a protected end-system are switched from a primary end-system to a backup end-system. The backup end-system may be selected a priori, for example, during connection establishment, in order to reduce switching time once a decision has been made to switch communications from the primary end-system to the backup end-system. Provisions are made for completing the alternate site switching within a specified amount of time. Load balancing may be used to further reduce switching time from the primary end-system to the backup end-system. This alternate site switching augments the various protection mechanisms provided by the core optical communication network in order to provide end-to-end protection for the optical communication path.

摘要： A method for improving modal bandwidth in computer networks using multimode optical fiber and laser sources is disclosed in which an annular beam is generate by the laser source, thus preventing center fiber transmission modes from reaching the detector. This prevents or lessens a pulse-splitting effect at the detector. The annular beam is generated preferably by configuring a vertical cavity surface emitting laser to have a center totally-reflecting block of 5-7 microns to generate a substantially dark-centered beam.
