    摘要： Wavelength assignment schemes that provide full-connectivity in RANs with fixed-tuned OADMs. In the first scheme, wavelengths are assigned to nodes according to Hadamard code, and in the second scheme, bands of contiguous wavelengths are assigned to nodes. Simulation results show that on the average, the Hadamard wavelength assignment schemes approach the performance of RANs with OADMs that add-drop all wavelengths, while saving 50% of the TDM terminals. The saving of TDM terminals by using wavelength tunable OADMs vary in different cases. Tunable OADMs are advantageous for lower traffic granularity and more interactions of a RAN with the outside network.

    摘要： In a communication system using multicasting, multicast packets are forwarded through a switch by destination ports after these ports receive the packets. A source node sends the multicast packet to a subset of nodes within the multicast group, which in turn, forward the multicast packet to other subsets of packets within the multicast group that have yet to receive the information. This is continued until all ports within the multicast group have received the information.

    摘要翻译： 在使用组播的通信系统中，在这些端口收到数据包后，组播数据包将通过交换机转发到目的端口。 源节点将组播数据包发送到组播组内的节点子集，然后又将组播数据包转发到组播组中尚未接收到该信息的其他子集。 这是持续的，直到多播组中的所有端口都收到信息。

    摘要： A system and method for a transparent WDM metro ring architecture in which optics enables simultaneous provisioning of dedicated wavelengths for high-end user terminals, while low-end user terminals share wavelengths on “virtual rings”. All wavelengths are sourced by the network and remotely modulated at customer “End Stations” by low cost semiconductor optical amplifiers, which also serve as transmission amplifiers. The transparent WDM metro ring architecture permits the communication of information and comprises a fiber optical feeder ring, at least one fiber optical distribution ring, a network node (NN), at least one access node (AN) said network node and said at least one access node connected via said fiber optical feeder ring and at least one end station (ES) connected via said fiber optical distribution ring to said at least one access node, wherein said user is attached to said at least one end station. A simple node that supports bi-directional propagation in transparent WDM metro architectures using “virtual rings” is also described. A method for communicating information over a WDM fiber optical ring network architecture in a metro access arena using one or more wavelengths, which can be shared by a plurality of user terminals, each user terminal coupled to an end station comprises the steps of sending downstream data packets, sending optical chalkboard packets consisting of ones and sending control signals.

    摘要： Apparatus for flexible sharing of bandwidth in switches with input buffering by dividing time into a plurality of frames of time slots, wherein each frame has a specified integer value of time slots. The apparatus includes modules where inputs sequentially select available outputs to which the inputs send packets in specified future time slots. The selection of outputs by the inputs is done using a pipeline technique and a schedule is calculated within multiple time slots.
