The bandwidth ceilings are bandwidth diagonals placed below the idealized peak bandwidth diagonal. Their existence is due to the lack of some kind of memory related architectural optimization, such as cache coherence , or software optimization, such as poor exposure of concurrency (that in turn limit bandwidth usage).
The consumed bandwidth in bit/s, corresponds to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path.The consumed bandwidth can be affected by technologies such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth ...
It is thus similar to overhead in organizations. Computer system overhead shows up as slower processing, less memory, less storage capacity, less network bandwidth, or bigger latency than would be expected from reading the system specifications. [1] It is a special case of engineering overhead. Overhead can be a deciding factor in software ...
For discussions of this type, the terms 'throughput' and 'bandwidth' are often used interchangeably. The Time Window is the period over which the throughput is measured. The choice of an appropriate time window will often dominate calculations of throughput, and whether latency is taken into account or not will determine whether the latency ...
The bisection bandwidth of a network topology is the minimum bandwidth available between any two such partitions. [1] Given a graph G {\displaystyle G} with vertices V {\displaystyle V} , edges E {\displaystyle E} , and edge weights w {\displaystyle w} , the bisection bandwidth of G {\displaystyle G} is
In the latter case, inline appliances are preferred. These would generally 'sit' between the LAN and the LAN's exit point, generally the WAN or Internet router, and all packets leaving and entering the network would go through them. In most cases the appliance would operate as a bridge on the network so that it is undetectable by users.

For example, the 8 node butterfly network can be split into two by cutting 4 links that crisscross across the middle. Thus bisection bandwidth of this particular system is 4. It is a representative measure of the bandwidth bottleneck which restricts overall communication. Diameter: The worst case latency (between two nodes) possible in the ...
