摘要： A future-proof network comprising multiple independent core media and universal edge nodes is disclosed. The edge nodes are equipped to evaluate the performance of each of the core media. Network-fabric decoupling and, more importantly protocol decoupling, permit graceful retirement of inferior core media and growth of superior core media.

摘要： In a communication network comprising nodes and links between the nodes, a controller node disseminates routing information including nodal routing tables. A nodal routing table for a given node comprises alternate routes from the given node to other nodes in the network. A controller of the network receives traffic information from nodes and, based on the received traffic information, determines a set of adaptive routing information corresponding to each said node and transmits each set of adaptive routing information to the respective node. Determining the set of adaptive routing information is performed according to a courteous routing scheme. The routing scheme is labeled as “courteous” because, in a contention state, a node-pair that would suffer the least by directing a part of its traffic away from a preferred path yields to node pairs that suffer more by redirecting their traffic. Courteous routing increases the payload throughput and decreases real-time processing effort. A node, having received the set of adaptive routing information, initializes a set of vacancy vectors. The vacancy vectors are used while allocating incoming connection requests to routes. While a connection is allocated to a route, the available capacity of the allocated route, as reported in the vacancy vector, is reduced by the load of the allocated connection.

摘要： A wide-coverage, high-capacity, switching network is modeled after a classical space-time-space switch. In the switching network, each of the space stages comprises geographically distributed optical space switches and the time stage comprises a plurality of geographically distributed high-capacity electronic switching nodes. User-access concentrators, each supporting numerous users, access the network through ports of the distributed optical space switches. A user-access concentrator is a simple device which need only have a single access channel to access the network, although two or more access channels may be used. Such a user-access concentrator can communicate with a large number of other user-access concentrators by time-multiplexing the access channel.

摘要： An optical shell node is provided with an ability to perform time switching on signals received from subtending edge nodes and channel switching on signals received from other shell nodes and destined for the subtending edge nodes. The signals received from the subtending edge nodes may be aggregated into signals that are channel switched by optical core nodes or by other shell nodes toward destination edge nodes. A resultant network formed of these shell nodes along with channel-switching core nodes and subtending-upon-shell-node edge nodes is capable of expansion beyond a continental scale, can support large numbers of edge nodes and has a higher bit rate capacity than known optical network structures.

摘要： A network comprising a large number of electronic edge nodes interconnected through bufferless optical switch planes so that a signal from any edge node to any other edge node traverses only one switch plane scales to a capacity of hundreds of petabits per second while providing global geographic coverage. Each edge node is time-locked to each optical switch plane to which it connects to enable loss-free time-sharing of the network core despite the absence of buffers in the core. In an alternate implementation, a relatively small number of electronic switch units may be employed in a predominantly-optical core. In addition to scalability and high performance, the simple structure of the network significantly simplifies addressing and routing.

摘要： A method and a network for a universal transfer mode (UTM) of transferring data packets at a regulated bit rate are disclosed. The method defines a protocol that uses an adaptive packet header to simplify packet routing and increase transfer speed. The protocol supports a plurality of data formats. The network includes a plurality of modules that provide interfaces to various data sources. The modules are interconnected by an optic core with adequate inter-module links. The adaptive packet header is used for both signaling and payload transfer. The header is parsed to determine its function. Rate regulation is accomplished using each module control element and egress port controllers to regulate packet transfer. The protocol enables the modules to behave as a single distributed switch capable of multi-terabit transfer rates. The advantage is a high speed distributed switch capable of serving as a transfer backbone for substantially any telecommunications service.

摘要： A method of interleaving time-critical data packets and delay-tolerant data packets on a shared channel emanating from a control port of a switching node permits a strict time requirement for transmission of time-critical data packets to be met. A control circuit of the switching node stores a local time, an indication of a time required to transfer a delay-tolerant data packet waiting to be transferred, a comparator and a selector to control transfer of the time-critical and delay tolerant data packets.

摘要： An optical channel switch comprising independent optical space switches interconnects electronic data-switch modules to form a high-capacity wide-coverage network. The optical channel switch connects incoming wavelength-division-multiplexed (WDM) links each originating from a data-switch module to outgoing WDM links each terminating in a data-switch module. The optical space switches are of equal dimension, each having the same number of dual ports (input-output ports). The channels of incoming WDM links are assigned to the input ports of the space switches and the output ports of the space switches are assigned to channels of the outgoing WDM links in a manner which permits a switched path from any data-switch module to any other data-switch module even when the number of data-switch modules substantially exceeds the number of dual ports per space switch. A method of reconfiguring the channel switch in response to varying traffic demand is also disclosed.

摘要： A method is described for segmenting a data stream comprising variable-size packets, a data stream being defined by its source node, sink node, assigned network route, and other attributes. The segments are of equal size and the method concatenates the packets in successive segments in a manner that attempts to minimize segmentation waste without undue delay. The method facilitates the construction of efficient networks that scale to very high capacities while respecting service-quality specifications. Apparatus for implementing the method are also described.
