Performance evaluation of the MOQ switch recently proposed by us is discussed in this paper. In the MOQ switch both the switch fabric and buffers can operate at the same speed as input and output ports. This solution does not need any speedup in the switch fabric as well as any matching algorithms between inputs and outputs. The description and the first(More)
In this paper the new packet switch architecture with multiple output queuing (MOQ) is proposed. In this architecture the nonblocking switch fabric, which has the capacity of N ×N2 , and output buffers arranged into N separate queues for each output, are applied. Each of N queues in one output port stores packets directed to this output only from one input.(More)
The CBC stands for the Central-stage Buffered Clos-network. This kind of switching fabric was proposed and theoretically evaluated by F. Wang and M. Hamdi. In this paper new packet dispatching schemes for the CBC switches are proposed and evaluated. We study three such schemes, called RGNA (Request – Grant with No Association), RGAM (Request Grant with(More)
Rapid expansion of the Internet and increasing demand for multimedia services fosters an immediate need for the development of new high-capacity networks capable of supporting these growing bandwidth requirements. The development of broadband transport networks resulted in the need for next generation switches/routers with high-speed interfaces and large(More)
In this paper new packet dispatching schemes for efficient support of the uniform as well as the nonuniform traffic distribution patterns in Memory-Space-Memory (MSM) Closnetwork switches are presented. Three such schemes, called Static Dispatching-First Choice (SD-FC), Static Dispatching-Optimal Choice (SD-OC) and Input Module (IM)-Output Module (OM)(More)
The multi-plane banyan-type switching fabric is a very promising architecture for building nonblocking optical switches. To avoid blocking states many copies of planes, i.e. log2N switching fabrics are connected in parallel, so we call this structure multi-plane. In this paper, repackably nonblocking multi-plane banyan-type switching fabrics are considered.(More)
