A new network architecture for future optical networks : coarse optical circuit switching by default, rerouting over circuits for adaptation
As Internet traffic continues to grow unabated at an exponential rate, it is unclear whether the existing packet-routing network architecture based on electronic routers will continue to scale at the necessary pace. On the other hand, optical fiber and switching elements have demonstrated an abundance of capacity that appears to be unmatched by electronic routers. In particular, the simplicity ...
متن کاملAn Analytical Model of Fully-Adaptive Wormhole-Routed k-Ary n-Cubes in the Presence of Hot Spot Traffic
Several analytical models of fully-adaptive routing have recently been proposed for wormhole-routed k-ary ncubes under the uniform traffic pattern. However, there has been hardly any model reported yet that deals with other important non-uniform traffic patterns, such as hot spots. As a result, most studies have resorted to simulation when evaluating the performance merits of adaptive routing. ...
متن کاملInvestigating QoS Support for Traffic Mixes with the MediaWorm Router
With the increasing use of clusters in real-time applications, it has become essential to design high performance networks with quality of service (QoS) guarantees. In this paper, we explore the feasibility of providing QoS in wormhole switched routers, which are otherwise well known for designing high performance interconnects. In particular, we are interested in supporting multimedia video st...
متن کاملAn accurate performance model of shared buffer ATM switches under hot spot traffic
Asynchronous transfer mode (ATM) switches based on shared buffering are known to have better performance and buffer utilization than input or output queued switches. Shared buffer switches do not suffer from head of line blocking which is a problem in simple input buffering. Shared buffer switches have previously been studied under uniform and unbalanced traffic patterns. However, due to the co...
متن کاملImprovement of Packet Loss Probability by Complementer in Dilated Banyan Switch under Hot-Spot Traffic
Packet contention is one of the fundamental problems that must be overcome in designing packet switches. In banyan network, which has multistage interconnection structure of many small switch elements, we must be concerned with output port conflicts and internal collisions. Dilated banyan network which provides multiple path for internal link can reduce packet loss due to internal collisions in...
