Bandwidth unidirectional

When evaluating parallel network performance, it is important to ascertain whether reported bandwidth data refer to unidirectional or bidirectional bandwidths. Most communication networks provide bidirectional communication channels, which are able to transmit messages in both directions... 

Latency a, inverse bandwidth p, and bandwidth for Gigabit Ethernet (GigE) and InfiniBand (using IPoIB) interconnects on a Linux cluster. Data were determined using the program shown in Figure 5.2, and the reported bandwidths are unidirectional... 

The major function of the ATM layer is to provide fast multiplexing and routing for data transfer based on the header information. The ATM layer is divided into two sublayers virtual path and virtual channel. A VC is a generic term used to describe a unidirectional communication capability for the transport of ATM cells. The VC identifies an end-to-end connection that can be set via either provisioning (permanent VC) or near real-time call setup (switched VC). Either way the bandwidth capacity of that connection is determined in real-time depending on traffic to be transported over that connection. 

Traffic regulation is made via Virtual Links (VL), which are defined as objects to establish a logical unidirectional connection from one source end system to one or more destination end systems crossing one or more AFDX switches. Each VL has a dedicated maximum bandwidth that is characterized by two parameters ...
