10 Mar 2020TL;DR: In this article, an optical transmitter (800) is operative to generate, from a plurality of encoded client bits (808, 810), a set of symbols (814) exhibiting non-uniform visitation probabilities in at least one dimension, to encode the set of symbol across a number of frequency division multiplexing 'FDM' subcarriers using a permutation function (811), and to transmit an optical signal (864) comprising the plurality of FDM sub-carriers across which the sets of symbols is encoded.
Abstract: An optical transmitter (800) is operative to generate, from a plurality of encoded client bits (808, 810), a set of symbols (814) exhibiting non-uniform visitation probabilities in at least one dimension, to encode the set of symbols across a plurality of frequency division multiplexing 'FDM' subcarriers using a permutation function (811), and to transmit an optical signal (864) comprising the plurality of FDM subcarriers across which the set of symbols is encoded. An optical receiver (900) is operative to decode a set of symbol estimates (916) from a plurality of FDM subcarriers using an inverse permutation function (911), the symbol estimates comprising estimates of symbols exhibiting non-uniform visitation probabilities in at least one dimension, and to recover client bits (902) from the set of symbol estimates.

02 Feb 2004TL;DR: In this article, a flexible bandwidth advertisement method that can reduce the number of routing updates that are sent in a network is presented. But it does not address the problem of bandwidth adaption.
Abstract: An embodiment of the invention provides a flexible bandwidth advertisement method that can reduce the number of routing updates that are sent in a network. In an embodiment of the invention, a method of reducing available bandwidth updates in a link in a communication system is provided. The method includes setting a range of threshold values. An actual available bandwidth in the link is then changed. If the actual available bandwidth changes from a first value within the range of threshold values to a second value within the range of threshold values, then a transmission of an available bandwidth update on the link is then prevented.

28 Jan 2000TL;DR: In this paper, a method for operating a redundant optical communication network has at least two network transmission paths, assigns first and second protection protocols to switched signals and secondary signals respectively, adds and drops the switches and the secondary signals on the at least 2N transmission paths.
Abstract: A method for operating a redundant optical communication network has at least two network transmission paths, assigns first and second protection protocols to switched signals and secondary signals respectively, adds and drops the switched signals and secondary signals on the at least two network transmission paths, makes the switched signals and the secondary signals to counter-propagate along the at least two network transmission paths, therefore, the redundant optical communication network can support different data types and different protection mechanisms. An optical communication network configured by the method of the present invention includes at least two network transmission paths, a first and a second processing means for processing switched signals and secondary signals in accordance a first protection protocol and a second protection protocol respectively, a primary and a secondary add/drop mechanisms for selectively adding and dropping the switched signals and secondary signals to counter-propagate along said at least transmission paths. The network can support different data types and different protection mechanisms.

08 Oct 2002TL;DR: In this paper, the available priority bandwidth for the requested priority exceeds the requested bandwidth, and the switch creates a provisional connectional which is committed to an actual connection in a subsequent connect phase.
Abstract: A method and system for allocating bandwidth in an optical communication system. During a set-up phase, a set-up message including requesting a connection is generated and includes a requested priority and requested bandwidth. When a switch receives the set-up message, the switch determines whether the available priority bandwidth for the requested priority exceeds the requested bandwidth. If the available priority bandwidth for the requested priority exceeds the requested bandwidth, the switch creates a provisional connectional which is committed to an actual connection in a subsequent connect phase. If the available priority bandwidth for the requested priority does not exceed the requested bandwidth, then the switch rejects the connection to provide a fast release.

TL;DR: A content caching system enables an NDN network to place content closer to each end user(s) and to provide an explicit path for the target end users to that content for better performance just in advance of users' anticipated request(s).
Abstract: A content caching system enables an NDN network to place content closer to each end user(s) and to provide an explicit path for the target end user(s) to that content for better performance just in advance of users' anticipated request(s). The apparatus includes NDN routers and SDN controller employing a content commander, at least a content placement agent and at least one content analysis agent.
