摘要： A method and apparatus for encoding and decoding m-bit groups of digital data, where m is at least eight, into serial n bit groups such that each encoded serial n-bit group has sufficient data transitions therein to maintain the synchronization of a phase locked loop clock recovery circuit in a high speed serial link of a communication path. Further, this method and apparatus provides a duty cycle that is within an operational range of the ideal 50 percent, which reduces voltage drift of a.c. coupled high speed serial data links, or reduces thermal drift of optically coupled high speed serial data links.

摘要： A telecommunications switch which has a central switch fabric made up of multiple crossbars that can be used to switch either circuit switched or packet switch communications as long as appropriate input and output interfaces and controllers are provided. Thus, a large, high throughput telecommunications switch is provided where the expensive switch fabric core can remain the same and the interfaces and control cards changed as the relative demands for circuit switched communications and packet switched communications, such as ATM, evolve. Besides being flexible, this switch may also be fault tolerant.

摘要： A multi-stage network which achieves the same overall connectivity as known networks but where individual switching nodes have no input selectivity and no output selectivity. Each node is enabled or disabled to control communication therethrough in response to a single control signal. The functionality of a switching network is achieved by controlling which nodes are enabled rather than specifying connections of particular node inputs and outputs to be effected by the nodes. In a photonic network embodiment, each network node is implemented using a single symmetric self electro-optic effect device (S-SEED).

摘要： A growable packet switching arrangement where the distribution network blocking probability is substantially reduced because the network has both switch links and chute links, and the network nodes include both a switching element interconnecting successive stage switch links and a plurality of non-switching, chute connections interconnecting successive stage chute links. A network node can transfer a packet, being received on a switch link, to any selected one of the chute connections of that node for transmission on a chute link. The network nodes are relatively simple and inexpensive because they store only the first few bits needed to route an ATM cell. The blocking probability is further reduced when the number of chutes per node is increased. The number of chutes may be based, for example, on the number of switch link inputs per node.

摘要： A reduced-blocking system where a perfect shuffle equivalent network having a plurality of node stages successively interconnected by link stages, is advantageously combined with expansion before the node stages and/or concentration after the node stages in a manner allowing the design of a system with arbitrarily low or zero blocking probability. An illustrative photonic system implementation uses free-space optical apparatus to effect a low loss, crossover interconnection of two-dimensional arrays of switching nodes comprising, for example, symmetric self electro-optic effect devices (S-SEEDs). Several low loss beam conbination techniques are used to direct multiple arrays of beams to an S-SEED array, and to redirect a reflected output beam array to a subsequent node stage.

摘要： A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.

摘要： A new dimension for growth is presented for the generalized growable packet switch architecture. That dimension is time and by rolling routing requests around a distributed out-of-band controller ring, ATM cell traffic can be controlled and spread across two time intervals. The rolling of routing requests and the resulting time spreading of the cell traffic through the distribution network averages out bursts and localized hot spots, thereby reducing blocking and improving cell loss probabilities with only small increases in hardware cost and complexity.
