SLC´s adaptation of the ALS high performance serial link

The Keep It Simple Network (KISNet) is a very high speed, low overhead, primarily point-to-point network adapted from the LBL Advanced Light Source (ALS) control system. KISNet implements the ALS system in the SLAC Linear Collider (SLC) environment. Commercially available communication hardware and protocols do not meet the per-small-packet transmission time requirements of the initial application that motivated the development of KISNet. In the SLC environment, the communications system is used in a slightly different way than at ALS. The software is layered to enable insertion of future hardware as it becomes available. Several enhancements for the future of KISNet are under consideration.<>
