In computer networks, cut-through architecture is a method used for packet switching system. In this system the data frame or packets begin to leave the switch almost as soon as they begin to enter the switch. Simply put, a cut through architecture does not store a data frame and then forward it. On the other hand, the other device holds the entire frame for a short period of time while the various fields of the frame are examined, this procedure makes the overall network throughput very slow or decreases it. This method is known as the store and forward method. In contrast, cut through architecture allows a switch to pass data very quickly and improves the overall throughput of the network, but cut through also allows error frames to be forwarded which is its main disadvantage. For example, a storage and forwarding device will input the frame, perform several checking operations such as cyclic checksum, detect the error, and perform some operations to check the error if the frames or packet are corrupted. However, a cut-through device is so fast that it starts forwarding the frame before the cyclic checksum and in that case the bad frame has also been transmitted, if the packet contains too many bad frames and is transmitted over the network, the integrity of the network is greatly affected. In many data centers, latency and jitter are the most important parameters. Even a small delay can have a negative impact on network performance. To reduce jitter and delay in a network, a cut through architecture is required. Director x stream and Ilinkagg x stream are the programs based on cut through architecture that provide the necessary low latency and predictable jitter that allows data center architects and designers to create the best solution that mee......half of the sheet......REFERENCES(Sharon Besser, 2011).
