What is Communication Streaming Architecture (CSA)?

What does CSA stand for?

Communication Streaming Architecture (CSA) is a verbal excHange Interface evolved by way of Intel that links the reminiscence Controller hub (MCH) on the Chipset to the Network conTroller. The Device is an individualized connection that does not use the Peripheral factor Interconnect (PCI) Bus at the enter/Output (I/O) controller hub. The CSA offloads Network Traffic from the PCI bus and reduces bottlenecks through Freeing up Bandwidth for other I/O techniques.

The CSA turned into simplest used for the Intel Chipset that was synthetic in 2003. It changed into Discontinued a year later and replaced with the aid of the PCI Express.

What Does Communication Streaming Architecture Mean?

By going around the PCI bus, the CSA notably reduces the quantity of bottlenecks, which may be a problem for PCI architectures. A bottleneck is while the transmission of facts is delayed, impaired or absolutely stopped. The CSA reduces bottlenecks by way of offloading network traffic from the PCI bus, which frees the bandwidth for further I/O operations. In addition, other devices just like the USB or Optical Disk drives which include DVD-ROM which are linked to the I/O Controller hub (ICH) can use freed bandwidth.

The CSA had two key benefits:

• Lower Latencies: Read/Write Memory Procedures had fewer delays due to the fact inFormation turned into sent straight from the commUnity interface to the random get entry to memory (RAM).
• Decrease in Data Crisscrossing: The quantity of traverses is reduce in half due to the CSA’s direct direction, thereby lowering additional Latency in network transmission.

Because of its continually high Switch Charges, the CSA was regularly used with Gigabit Ethernet and was usually favored over PCI playing cards. However, the PCI Express provided a whole lot better statistics switch charges, Rendering CSA out of date.
